A <a href=\"https:\/\/austins.website\/consulting\/migrations\/\">website migration SEO<\/a> plan helps reduce that risk.<\/p>\n<p>The reason is simple. Search engines do not experience a website migration the same way your users or development team do.<\/p>\n<p>Google has already discovered URLs on your existing site, crawled their content, evaluated internal links and backlinks, processed canonical tags and structured data, and decided which pages belong in its index. When you change those signals, Google has to process the changes and determine what the new website means.<\/p>\n<p>That creates risk.<\/p>\n<p>A poorly planned website migration can result in broken links, 404 errors, redirect chains, lost backlinks, duplicate content, indexing issues, and falling keyword rankings. A well-planned migration gives search engine crawlers a clear path from the old website to the new one while preserving as much SEO value as possible.<\/p>\n<p>This SEO migration checklist breaks that process into three phases:<\/p>\n<ol>\n<li>Pre-migration: Benchmark, crawl, map, and test.<\/li>\n<li>Migration: Launch the new site and validate critical SEO signals.<\/li>\n<li>Post-migration: Monitor crawling, indexing, rankings, traffic, and conversions.<\/li>\n<\/ol>\n<p>The checklist applies whether you are completing a website redesign, moving to a new content management system (CMS), changing domains, consolidating subdomains, switching your URL structure, or performing another major site migration.<\/p>\n<p>The exact implementation will vary by migration type, but the objective remains the same:<\/p>\n<p><strong>Change what needs to change without unnecessarily changing the SEO signals that already work.<\/strong><\/p>\n<h2>Phase 1: Pre-Migration SEO Checklist<\/h2>\n<p>Most migration problems should be solved before launch.<\/p>\n<p>Once a new site is live, crawl errors and missing redirects can immediately affect users and search engine crawlers. Pre-migration work gives your SEO, development, content, and analytics teams time to find those problems without production traffic on the line.<\/p>\n<h3>1. Define the Scope of the Website Migration<\/h3>\n<p>Start by documenting exactly what is changing.<\/p>\n<p>A website migration can include:<\/p>\n<ul>\n<li>A domain migration<\/li>\n<li>HTTP to HTTPS migration<\/li>\n<li>A CMS change (for example, moving to or between WordPress installs)<\/li>\n<li>A hosting provider change<\/li>\n<li>A website redesign<\/li>\n<li>Changes to site architecture<\/li>\n<li>Changes to URL structure<\/li>\n<li>Subdomain consolidation or separation<\/li>\n<li>Rebranding<\/li>\n<li>Content consolidation<\/li>\n<li>Multiple changes occurring simultaneously<\/li>\n<\/ul>\n<p>Scope matters because risk compounds.<\/p>\n<p>Moving a site to a new CMS while changing the domain, site structure, page templates, content, and URLs gives search engines considerably more information to process than a design update that leaves the underlying URLs and content intact.<\/p>\n<p>Avoid combining unnecessary changes simply because a migration creates an opportunity to make them.<\/p>\n<p>If a URL already ranks, earns backlinks, receives organic traffic, and accurately describes its content, there should be a clear reason to change it.<\/p>\n<p>Document the required changes and separate them from changes that are merely nice to have.<\/p>\n<p>For complex projects, consider working with a provider that offers <a href=\"https:\/\/austins.website\/blog\/website-migration-services\/\">website migration services<\/a> so technical, content, and SEO requirements are coordinated before launch.<\/p>\n<h3>2. Establish Migration KPIs and Benchmarks<\/h3>\n<p>You cannot accurately measure the SEO impact of a migration without knowing how the existing site performs.<\/p>\n<p>Before development is complete, establish baseline KPIs for the existing website.<\/p>\n<p>At minimum, record:<\/p>\n<ul>\n<li>Organic traffic<\/li>\n<li>Organic conversions<\/li>\n<li>Conversion rates<\/li>\n<li>Bounce rates<\/li>\n<li>Keyword rankings<\/li>\n<li>Organic visibility<\/li>\n<li>Indexed pages<\/li>\n<li>Top landing pages<\/li>\n<li>Backlinks<\/li>\n<li>Core Web Vitals<\/li>\n<li>Page speed<\/li>\n<li>Crawl errors<\/li>\n<\/ul>\n<p>Pull historical data from Google Analytics and Google Search Console. Depending on your reporting stack, tools such as Semrush may provide additional keyword rankings and organic visibility benchmarks.<\/p>\n<p>Do not evaluate the migration using traffic alone.<\/p>\n<p>Seasonality, demand, paid campaigns, rebranding, economic conditions, and other marketing activity can affect sessions. Conversion rates and organic conversions help determine whether the new site is preserving business performance in addition to search engine rankings.<\/p>\n<p>If paid acquisition is part of the broader launch plan, coordinate SEO reporting with your <a href=\"https:\/\/pointsourcemarketing.com\/\" target=\"_blank\" rel=\"noopener\">performance marketing agency<\/a> so organic and paid changes are interpreted in context.<\/p>\n<p>Create an annotated launch date in your reporting so pre- and post-migration performance can be compared consistently.<\/p>\n<h3>3. Crawl the Existing Website<\/h3>\n<p>Before changing anything, create a record of the current website.<\/p>\n<p>Run a complete site crawl with a crawler such as Screaming Frog and export the results.<\/p>\n<p>Capture information including:<\/p>\n<ul>\n<li>Existing URLs<\/li>\n<li>Status code<\/li>\n<li>Page titles<\/li>\n<li>Meta descriptions<\/li>\n<li>H1s<\/li>\n<li>Canonical tags<\/li>\n<li>Indexability<\/li>\n<li>Internal links<\/li>\n<li>Redirects<\/li>\n<li>Images<\/li>\n<li>Structured data<\/li>\n<\/ul>\n<p>This crawl becomes a reference point after launch.<\/p>\n<p>Do not assume your XML sitemap contains every important URL. Sitemaps can be outdated or incomplete, and orphan pages may not appear in the normal site architecture.<\/p>\n<p>Combine crawl data with URLs found in Google Analytics, Google Search Console, your backlink profile, and your CMS.<\/p>\n<p>Your goal is to build the most complete possible inventory of URLs that currently have SEO or business value.<\/p>\n<h3>4. Identify Your Highest-Value URLs<\/h3>\n<p>Not every URL represents equal migration risk.<\/p>\n<p>A page receiving 20,000 organic visits per month and hundreds of backlinks requires more scrutiny than an obsolete page that has never generated traffic.<\/p>\n<p>Segment URLs based on signals such as:<\/p>\n<ul>\n<li>Organic traffic<\/li>\n<li>Conversions<\/li>\n<li>Keyword rankings<\/li>\n<li>Backlinks<\/li>\n<li>Revenue or lead generation<\/li>\n<li>Internal link prominence<\/li>\n<\/ul>\n<p>Pay particular attention to URLs that rank for commercially valuable queries or possess strong link equity.<\/p>\n<p>These URLs should receive priority during URL mapping, redirect testing, content review, and post-launch monitoring.<\/p>\n<p>A migration is not the time to discover that your highest-converting organic landing page disappeared three days ago.<\/p>\n<h3>5. Create a Complete Redirect Map<\/h3>\n<p>The redirect map is one of the most important parts of a website migration SEO checklist.<\/p>\n<p>For every URL that will change, determine its most appropriate destination on the new site.<\/p>\n<p>Your redirect map should contain at least:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Old URL<\/th>\n<th>New URL<\/th>\n<th>Action<\/th>\n<\/tr>\n<tr>\n<td>\/old-service\/<\/td>\n<td>\/services\/new-service\/<\/td>\n<td>301 redirect<\/td>\n<\/tr>\n<tr>\n<td>\/old-about\/<\/td>\n<td>\/about\/<\/td>\n<td>301 redirect<\/td>\n<\/tr>\n<tr>\n<td>\/obsolete-page\/<\/td>\n<td>Relevant replacement<\/td>\n<td>301 redirect or remove<\/td>\n<\/tr>\n<tr>\n<td>\/unchanged-page\/<\/td>\n<td>\/unchanged-page\/<\/td>\n<td>No redirect required<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>URL mapping should happen at the individual page level whenever practical.<\/p>\n<p>Avoid sending large groups of old URLs to the homepage simply because it is convenient. The destination should provide a useful and relevant replacement for the old page.<\/p>\n<p>Use permanent 301 redirects when a page has permanently moved.<\/p>\n<p>The redirect map should also account for URLs discovered through analytics, backlinks, old XML sitemaps, previous redirects, and crawl data.<\/p>\n<p>This is tedious work.<\/p>\n<p>It is also considerably less tedious than trying to diagnose a large organic traffic decline after launch.<\/p>\n<h3>6. Eliminate Redirect Chains Before Launch<\/h3>\n<p>A migration can accidentally stack new redirects on top of old ones.<\/p>\n<p>For example:<\/p>\n<p>URL A &rarr; URL B &rarr; URL C &rarr; URL D<\/p>\n<p>That redirect chain creates unnecessary requests for users and crawlers.<\/p>\n<p>Instead, update the redirect so the original URL points directly to the final destination:<\/p>\n<p>URL A &rarr; URL D<\/p>\n<p>Review existing redirects when building your redirect map and identify chains before the new rules are deployed.<\/p>\n<p>This is particularly important for sites that have been through multiple redesigns or migrations. A website that has existed for ten years may be carrying technical decisions from three CMS platforms ago.<\/p>\n<h3>7. Preserve High-Value Content and On-Page Signals<\/h3>\n<p>A redesign can unintentionally become a content migration.<\/p>\n<p>Pages get shorter because the new template has less room. Headings disappear. Internal links get removed. Title tags are rewritten. Useful copy gets replaced with generic brand language.<\/p>\n<p>Then everyone wonders why rankings changed.<\/p>\n<p>For important pages, compare the old and new versions before launch.<\/p>\n<p>Review:<\/p>\n<ul>\n<li>Primary content<\/li>\n<li>Headings<\/li>\n<li>Page titles<\/li>\n<li>Meta descriptions<\/li>\n<li>Internal links<\/li>\n<li>Images and alt attributes<\/li>\n<li>Structured data<\/li>\n<li>Canonical tags<\/li>\n<\/ul>\n<p>You do not need to freeze the old site permanently. The purpose of a redesign is often to improve content and user experience.<\/p>\n<p>But understand which SEO signals you are changing and why.<\/p>\n<p>If a page performs well in organic search, avoid stripping away relevant content simply to make the template look cleaner.<\/p>\n<h3>8. Review the New URL Structure<\/h3>\n<p>If URLs need to change, establish consistent rules before developers begin creating them.<\/p>\n<p>A good URL structure should be:<\/p>\n<ul>\n<li>Descriptive<\/li>\n<li>Consistent<\/li>\n<li>Easy to understand<\/li>\n<li>Stable<\/li>\n<li>Free of unnecessary parameters<\/li>\n<li>Aligned with the site&#8217;s information architecture<\/li>\n<\/ul>\n<p>Do not change URLs for cosmetic reasons alone.<\/p>\n<p>If \/seo-consulting\/ already performs well, changing it to \/services\/search\/seo-consulting-services\/ does not automatically make it more optimized.<\/p>\n<p>Every unnecessary URL change adds another redirect, another mapping requirement, and another opportunity for something to go wrong.<\/p>\n<h3>9. Audit Internal Links on the Staging Site<\/h3>\n<p>Internal links should point directly to final URLs rather than relying on redirects.<\/p>\n<p>For example, if:<\/p>\n<p>\/old-page\/ &rarr; \/new-page\/<\/p>\n<p>your navigation and body copy should link directly to \/new-page\/.<\/p>\n<p>Do not intentionally launch a new site full of internal links pointing through 301 redirects.<\/p>\n<p>Crawl the staging site and identify links pointing to:<\/p>\n<ul>\n<li>Old URLs<\/li>\n<li>Redirected URLs<\/li>\n<li>404 pages<\/li>\n<li>Development URLs<\/li>\n<li>Incorrect domains or subdomains<\/li>\n<\/ul>\n<p>Update internal links before launch whenever possible.<\/p>\n<p>This reduces unnecessary redirects and makes the new site architecture easier for crawlers to interpret.<\/p>\n<h3>10. Check Canonical Tags<\/h3>\n<p>Canonical tags tell search engines which URL should be treated as the preferred version of a page.<\/p>\n<p>Staging sites frequently inherit incorrect canonicals.<\/p>\n<p>Before launch, verify that canonical tags:<\/p>\n<ul>\n<li>Use the production domain<\/li>\n<li>Point to the correct preferred URLs<\/li>\n<li>Use the correct protocol<\/li>\n<li>Do not reference staging URLs<\/li>\n<li>Are consistent with redirects<\/li>\n<li>Do not accidentally canonicalize important pages elsewhere<\/li>\n<\/ul>\n<p>Canonical configuration becomes particularly important when URL parameters, duplicate content, ecommerce filtering, or similar page variants are involved.<\/p>\n<p>A technically functional website can still send completely contradictory indexing signals.<\/p>\n<h3>11. Validate Robots.txt and Noindex Directives<\/h3>\n<p>Staging environments should normally be protected from indexing.<\/p>\n<p>The problem occurs when those protections follow the website into production.<\/p>\n<p>Review robots.txt and page-level robots directives before launch.<\/p>\n<p>Confirm that the production site does not accidentally block search engine crawlers from important directories.<\/p>\n<p>Also look for any noindex tag that was applied during development and should not exist on production pages.<\/p>\n<p>This deserves its own launch checklist item because a single configuration mistake can create sitewide indexing issues.<\/p>\n<h3>12. Review the XML Sitemap<\/h3>\n<p>Generate an XML sitemap containing the canonical, indexable URLs you want search engines to discover.<\/p>\n<p>The XML sitemap should not contain:<\/p>\n<ul>\n<li>Redirecting URLs<\/li>\n<li>404 errors<\/li>\n<li>Noindexed pages<\/li>\n<li>Staging URLs<\/li>\n<li>Duplicate URLs<\/li>\n<li>Noncanonical URLs<\/li>\n<\/ul>\n<p>If the migration changes URLs substantially, prepare the new sitemap before launch so it can be validated and submitted through Google Search Console shortly after deployment.<\/p>\n<p>Large websites may require multiple XML sitemaps organized by page type or section.<\/p>\n<h3>13. Validate Structured Data<\/h3>\n<p>Templates can change structured data without anyone noticing.<\/p>\n<p>Test the staging site to ensure required structured data is still present and valid.<\/p>\n<p>Compare the old and new sites for relevant schema markup.<\/p>\n<p>Depending on the website, this may include structured data for organizations, products, articles, breadcrumbs, local businesses, or other supported entities.<\/p>\n<p>Do not assume a plugin or CMS migration will reproduce the old implementation correctly.<\/p>\n<h3>14. Test Core Web Vitals and Site Speed<\/h3>\n<p>A redesign should not ship with a major performance regression.<\/p>\n<p>Measure the staging site and compare it with the existing website.<\/p>\n<p>Pay particular attention to Core Web Vitals and the elements most likely to affect performance, including:<\/p>\n<ul>\n<li>Large images<\/li>\n<li>Video<\/li>\n<li>Web fonts<\/li>\n<li>JavaScript<\/li>\n<li>Third-party scripts<\/li>\n<li>Tag managers<\/li>\n<li>Consent platforms<\/li>\n<li>New page builders<\/li>\n<\/ul>\n<p>A staging environment will not always reproduce production performance exactly, but testing can expose obvious problems before users experience them.<\/p>\n<p>Site speed is also part of user experience. A beautiful redesign that takes significantly longer to load is not an unqualified improvement.<\/p>\n<h3>15. Verify Analytics and Conversion Tracking<\/h3>\n<p>Do not wait until after launch to discover your measurement disappeared.<\/p>\n<p>Confirm that the new website includes the required Google Analytics implementation and other approved measurement systems.<\/p>\n<p>Test important conversion actions, including:<\/p>\n<ul>\n<li>Form submissions<\/li>\n<li>Phone clicks<\/li>\n<li>Purchases<\/li>\n<li>Demo requests<\/li>\n<li>Account creation<\/li>\n<li>Other primary conversion events<\/li>\n<\/ul>\n<p>Confirm that tracking works across relevant templates and devices.<\/p>\n<p>Your migration KPIs become much less useful if the measurement system itself changes or breaks during launch.<\/p>\n<h3>16. Crawl and QA the Entire Staging Site<\/h3>\n<p>Complete a full SEO audit of the staging site before launch. If the migration involves substantial technical changes, a dedicated <a href=\"https:\/\/austins.website\/consulting\/technical-seo-audit\/\">technical SEO audit<\/a> can help identify issues before they reach production.<\/p>\n<p>The staging site crawl should look for:<\/p>\n<ul>\n<li>Broken links<\/li>\n<li>404 errors<\/li>\n<li>Incorrect status codes<\/li>\n<li>Missing title tags<\/li>\n<li>Missing metadata<\/li>\n<li>Duplicate content<\/li>\n<li>Incorrect canonical tags<\/li>\n<li>Indexing directives<\/li>\n<li>Crawl errors<\/li>\n<li>Redirects<\/li>\n<li>Incorrect internal links<\/li>\n<li>Missing structured data<\/li>\n<\/ul>\n<p>Compare the staging crawl with your existing-site crawl.<\/p>\n<p>This is where many migration mistakes become obvious.<\/p>\n<p>A site that had 2,000 indexed content pages before the migration probably deserves investigation if the new crawl suddenly contains 1,300 indexable URLs.<\/p>\n<h2>Phase 2: Migration and Launch Checklist<\/h2>\n<p>Launch day is not the time for improvisation.<\/p>\n<p>Your redirect map, crawl files, analytics benchmarks, staging QA, and rollback procedures should already exist.<\/p>\n<p>The migration itself should focus on implementing the approved plan and quickly validating that production behaves as expected.<\/p>\n<h3>17. Take a Final Crawl and Backup<\/h3>\n<p>Immediately before migration, create a final crawl of the old site.<\/p>\n<p>This gives you the most current reference for URLs, metadata, internal links, canonical configuration, and status codes.<\/p>\n<p>You should also confirm that the appropriate teams have a current backup and documented rollback process.<\/p>\n<p>SEO is only one part of migration risk. A failed deployment can create technical and operational problems far beyond organic search.<\/p>\n<h3>18. Deploy and Test 301 Redirects<\/h3>\n<p>Once the new website is live, immediately test the redirects from your approved redirect map.<\/p>\n<p>Do not spot-check three URLs and call it done.<\/p>\n<p>Test:<\/p>\n<ul>\n<li>High-traffic URLs<\/li>\n<li>URLs with backlinks<\/li>\n<li>Top-ranking pages<\/li>\n<li>Category and directory URLs<\/li>\n<li>Old redirected URLs<\/li>\n<li>URLs from previous site versions<\/li>\n<li>HTTP\/HTTPS variants where applicable<\/li>\n<li>www\/non-www variants where applicable<\/li>\n<\/ul>\n<p>Each old URL should return the intended status code and resolve to the correct final page.<\/p>\n<p>Look specifically for redirect chains, loops, irrelevant destinations, and unexpected 404 errors.<\/p>\n<h3>19. Remove Staging Restrictions<\/h3>\n<p>Verify that production can actually be crawled.<\/p>\n<p>Check robots.txt, authentication requirements, firewall rules, IP restrictions, and noindex directives.<\/p>\n<p>Then manually test several important production URLs.<\/p>\n<p>This sounds basic because it is basic.<\/p>\n<p>It is also one of the highest-impact mistakes a migration team can make.<\/p>\n<h3>20. Crawl the Production Website<\/h3>\n<p>Run a site crawl as soon as production is stable.<\/p>\n<p>Compare it with the approved staging crawl and your pre-migration crawl.<\/p>\n<p>Look for unexpected changes in:<\/p>\n<ul>\n<li>Indexable URL counts<\/li>\n<li>Status codes<\/li>\n<li>Canonical tags<\/li>\n<li>Page titles<\/li>\n<li>Meta descriptions<\/li>\n<li>Internal links<\/li>\n<li>Structured data<\/li>\n<li>Crawl depth<\/li>\n<\/ul>\n<p>Prioritize issues that affect crawling, indexing, redirects, or important landing pages.<\/p>\n<p>Cosmetic metadata improvements can wait. A blocked service directory cannot.<\/p>\n<h3>21. Update and Submit the XML Sitemap<\/h3>\n<p>Confirm that the production XML sitemap contains live production URLs and then submit it through Google Search Console.<\/p>\n<p>The sitemap gives Google a clean list of URLs you want it to crawl and index.<\/p>\n<p>For a domain migration, Google also provides a Change of Address tool in Search Console. Review the official <a href=\"https:\/\/support.google.com\/webmasters\/answer\/9370220?hl=en\" target=\"_blank\" rel=\"noopener\">Google Search Console Help documentation<\/a> before using it, and make sure redirects and the new sitemap are already in place.<\/p>\n<p>Continue monitoring the sitemap after submission for processing and indexing issues.<\/p>\n<p>If old URLs have changed, make sure your migration signals are consistent:<\/p>\n<p>Old URL &rarr; 301 &rarr; New URL<\/p>\n<p>Internal links &rarr; New URL<\/p>\n<p>Canonical tag &rarr; New URL<\/p>\n<p>XML sitemap &rarr; New URL<\/p>\n<p>The easier you make that relationship for crawlers to understand, the better.<\/p>\n<h3>22. Verify Google Search Console<\/h3>\n<p>Confirm that the correct Google Search Console properties are available to the people responsible for monitoring the migration.<\/p>\n<p>For a domain migration, make sure both old and new properties are configured appropriately.<\/p>\n<p>Use Search Console to monitor:<\/p>\n<ul>\n<li>Indexing<\/li>\n<li>Crawl activity<\/li>\n<li>Sitemap processing<\/li>\n<li>Search performance<\/li>\n<li>Page-level issues<\/li>\n<li>Core Web Vitals<\/li>\n<\/ul>\n<p>Do not treat Search Console as a launch-day-only tool. It becomes one of your primary diagnostic systems during the weeks following the migration.<\/p>\n<h3>23. Test Your Most Important User Journeys<\/h3>\n<p>SEO success is not simply maintaining keyword rankings.<\/p>\n<p>A page can retain its position and still generate fewer leads because the redesign made the form harder to use.<\/p>\n<p>Test important journeys from landing page through conversion.<\/p>\n<p>Review:<\/p>\n<ul>\n<li>Forms<\/li>\n<li>Calls to action<\/li>\n<li>Checkout processes<\/li>\n<li>Mobile usability<\/li>\n<li>Navigation<\/li>\n<li>Search<\/li>\n<li>Contact information<\/li>\n<li>Thank-you pages<\/li>\n<li>Conversion tracking<\/li>\n<\/ul>\n<p>Compare conversion rates with your pre-migration benchmarks once enough post-launch data is available.<\/p>\n<p>Search engine optimization should support business outcomes, not just produce pretty ranking charts.<\/p>\n<h2>Phase 3: Post-Migration SEO Checklist<\/h2>\n<p>The migration is not finished when the new site launches.<\/p>\n<p>Google still needs to crawl and index the changes, process redirects, reevaluate pages, and update search results.<\/p>\n<p>Post-migration monitoring is how you determine whether that process is working correctly.<\/p>\n<h3>24. Monitor Indexing<\/h3>\n<p>Track whether the new URLs are becoming indexed and whether obsolete URLs are disappearing as expected.<\/p>\n<p>Investigate unexpected patterns such as:<\/p>\n<ul>\n<li>Important pages remaining unindexed<\/li>\n<li>Large drops in indexed pages<\/li>\n<li>Staging URLs appearing in search<\/li>\n<li>Old URLs remaining indexed without appropriate redirects<\/li>\n<li>Canonical conflicts<\/li>\n<li>Pages excluded unexpectedly<\/li>\n<\/ul>\n<p>Not every difference indicates a problem. Google does not need to index every URL a CMS can generate.<\/p>\n<p>Focus on whether the pages that matter are crawlable, indexable, canonicalized correctly, and being discovered.<\/p>\n<h3>25. Monitor Organic Traffic and Keyword Rankings<\/h3>\n<p>Compare post-migration organic traffic and keyword rankings with your baseline.<\/p>\n<p>Prioritize page-level analysis over sitewide averages.<\/p>\n<p>If traffic drops, determine whether the decline is concentrated around:<\/p>\n<ul>\n<li>A directory<\/li>\n<li>A template<\/li>\n<li>A content type<\/li>\n<li>A group of changed URLs<\/li>\n<li>A specific keyword category<\/li>\n<\/ul>\n<p>That pattern can reveal the cause much faster than staring at the overall organic traffic chart.<\/p>\n<p>A ranking decline across pages using the same template, for example, may point to content or technical changes rather than redirects.<\/p>\n<h3>26. Monitor Crawl Errors and 404s<\/h3>\n<p>Watch for new crawl errors as search engines and users encounter old URLs.<\/p>\n<p>Some 404 errors are normal. Websites accumulate obsolete URLs over time, and not every deleted URL requires a redirect.<\/p>\n<p>Focus on 404s that:<\/p>\n<ul>\n<li>Previously received organic traffic<\/li>\n<li>Have backlinks<\/li>\n<li>Are still internally linked<\/li>\n<li>Have an obvious replacement<\/li>\n<li>Should have been included in the redirect map<\/li>\n<\/ul>\n<p>When appropriate, add a 301 redirect to the most relevant replacement.<\/p>\n<p>Do not redirect every 404 to the homepage.<\/p>\n<h3>27. Audit Backlinks and Reclaim Important Links<\/h3>\n<p>Backlinks pointing to an old URL can continue passing users through a properly implemented redirect, but updating valuable links to point directly to the new destination is still worthwhile.<\/p>\n<p>Review your backlink profile after migration and identify important links pointing to old URLs.<\/p>\n<p>Prioritize outreach when:<\/p>\n<ul>\n<li>A high-value backlink points to a broken page<\/li>\n<li>The redirect is incorrect<\/li>\n<li>The referring site can easily update its destination<\/li>\n<li>A domain migration has changed every URL<\/li>\n<\/ul>\n<p>For important owned profiles, directories, partner sites, and business listings, update the links directly.<\/p>\n<p>Good redirects help preserve link equity. Direct links remove the dependency on those redirects.<\/p>\n<h3>28. Update Internal Links You Missed<\/h3>\n<p>Your first production crawl will probably find something the staging audit missed.<\/p>\n<p>That is normal.<\/p>\n<p>Continue to update internal links pointing through redirects or to broken URLs.<\/p>\n<p>Pay particular attention to:<\/p>\n<ul>\n<li>Navigation<\/li>\n<li>Breadcrumbs<\/li>\n<li>Footer links<\/li>\n<li>Related-content modules<\/li>\n<li>Blog posts<\/li>\n<li>Hard-coded template links<\/li>\n<\/ul>\n<p>The objective is to make the production site&#8217;s internal link graph reflect the final site architecture.<\/p>\n<h3>29.

This can involve URL mapping, 301 redirects, internal links, canonical tags, XML sitemaps, robots.txt directives, structured data, and post-launch monitoring.<\/p>\n<p>The goal is not to prevent search engines from noticing that the website changed. The goal is to make those changes as clear and technically consistent as possible.<\/p>\n<h3>How do you migrate a website without losing SEO?<\/h3>\n<p>You cannot guarantee that keyword rankings or organic traffic will remain completely unchanged after a website migration.<\/p>\n<p>You can reduce unnecessary risk by documenting current performance, crawling the existing website, preserving valuable content, creating a page-level redirect map, implementing 301 redirects, updating internal links, validating canonical tags, checking robots.txt, submitting an accurate XML sitemap, and monitoring crawling and indexing after launch.<\/p>\n<p>The fewer unnecessary SEO signals you change simultaneously, the easier it generally is to diagnose problems.<\/p>\n<h3>How do I prepare for a site migration?<\/h3>\n<p>Start preparation before the new website is ready to launch.<\/p>\n<p>Crawl the existing site and combine those URLs with data from Google Analytics, Google Search Console, your CMS, XML sitemaps, and backlink tools. Identify your highest-value pages, create URL mapping for pages that will move, establish performance benchmarks, and thoroughly crawl the staging environment.<\/p>\n<p>Development, SEO, analytics, content, and other relevant teams should agree on the migration requirements before deployment.<\/p>\n<h3>What happens to my backlinks if my URLs change?<\/h3>\n<p>Existing backlinks continue pointing to the old URLs unless the referring websites update them.<\/p>\n<p>When an old page has an appropriate new equivalent, implement a permanent 301 redirect from the old URL to the new destination. This also prevents users clicking an old backlink from reaching a broken page.<\/p>\n<p>After migration, review your backlink profile and consider asking the owners of particularly valuable referring pages to update their links directly to the new URLs.<\/p>\n<h3>How long should I expect organic traffic to fluctuate after launch?<\/h3>\n<p>There is no universal recovery period for a site migration.<\/p>\n<p>Google must discover and process the changes, and the amount of time involved depends on factors such as the site&#8217;s size, crawl activity, migration complexity, number of changed URLs, internal linking, and technical implementation.<\/p>\n<p>Small fluctuations after launch do not automatically mean the migration failed. Significant or persistent declines, particularly when concentrated around specific templates or directories, should be investigated using crawl data, indexing reports, analytics, and ranking data.<\/p>\n<h3>Should URLs change during a website redesign?<\/h3>\n<p>Not unless there is a reason to change them.<\/p>\n<p>A website redesign does not inherently require a new URL structure.<\/p>\n<p>If existing URLs are descriptive, indexed, receiving organic traffic, earning backlinks, and performing well in search results, keeping them reduces migration complexity.<\/p>\n<p>Change URLs when doing so solves a real structural or technical problem, not simply because the website is getting a new design.<\/p>\n<h3>What should be included in an SEO migration checklist?<\/h3>\n<p>A website migration SEO checklist should cover the complete migration lifecycle.<\/p>\n<p>Before launch, it should include benchmarking, a site crawl, URL inventory, backlink analysis, URL mapping, a redirect map, internal links, canonical tags, robots.txt, XML sitemaps, structured data, metadata, Core Web Vitals, analytics, conversion tracking, and staging QA.<\/p>\n<p>During launch, it should cover redirect deployment, crawlability, production crawling, sitemap submission, Search Console verification, and conversion testing.<\/p>\n<p>After launch, the checklist should monitor indexed URLs, crawl errors, 404s, backlinks, keyword rankings, organic traffic, conversion rates, Core Web Vitals, and other migration KPIs until performance has stabilized.<\/p>\n<p>The technical details vary between migrations, but the principle is consistent: preserve valuable signals where possible and make every necessary change easy for users and search engines to understand.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Follow this SEO migration checklist to protect rankings and organic traffic before, during, and after a website redesign, CMS change, or domain migration.<\/p>\n","protected":false},"author":0,"featured_media":57,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"pagelayer_contact_templates":[],"_pagelayer_content":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-56","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/posts\/56","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/types\/post"}],"replies":[{"embeddable":true,"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/comments?post=56"}],"version-history":[{"count":0,"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/posts\/56\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/media\/57"}],"wp:attachment":[{"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/media?parent=56"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/categories?post=56"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/austins.website\/blog\/wp-json\/wp\/v2\/tags?post=56"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
