Does Website Migration Affect SEO?

Done well site migrations can be a boon for a site’s performance. In the past, one of my e-commerce clients noticed 200x traffic growth after SEO-assisted re-platforming migration. On the other side If migration happens without baking in SEO best practices it will risk the website's visibility and ranking across channels. Let me explain this using an example to make it easier for you


You run a Web Development Agency. You decided to update the " Progressive Web Apps Development service page" to “Single Page Application Development Services” i.e. need a change to URL & content. These new changes will result in losing rankings for discontinued pages, along with traffic, and audience. Also, create a poor experience for users accessing these discontinued web page from various sources i.e. internal web pages are external link sources. All these results in diminishing SEO authority the landing page has been established to date. This may not happen if you have taken assistance from an SEO specialist. Why because he/she would have suggested you implement redirection from the old URL to the new URL, this could diminish the impact the change had resulted.


So I would always recommend business webmasters implement Site migrations assisted by SEO specialists.

SEO Website Migration Strategies Webmasters Need to Consider When Refreshing their Websites?

Know when to start implementing website migration?

Website migrations happen when businesses decide to make either of these following changes i.e.,

  • Changing domain name

  • Rebranding

  • Upgrading from HTTP to HTTPS protocol

  • Merging multiple domains into one

  • Targeting an international audience or introducing a new language to locals

  • Replatforming or moving to a new CMS

  • Consolidating page content i.e. merging multiple pages

  • Changing subdomain to the directory or changing URL structure or hierarchy changes or navigation changes

Due to any of the above reasons, if when site owners decided to go for migration, they needed to create an Inventory of all indexable webpages, top-performing pages using XML sitemap, crawled data, and Analytics landing page data (consider 12-month traffic, performance data) as sources. Also, build a baseline report with keywords rankings, and SEO KPIs metrics to compare the performance of the website Pre & Post-launch.


Consider Including SEO through website migration.

SEO Led Migration Can help Businesses roll out website changes without losing hard-earned SEO value & traffic.


Finalize the New Website Webpage URLs & Build Redirection Map


After implementing all the recommendations on the new website provided by all stack holders, considering business requirements, and fulfilling the goal of Website migration, it's time to finalize URLs, navigation path, and hierarchy or taxonomy. Firstly, get all the required inputs i.e. target keywords for each webpage, confirmed URL best practices, etc. Then map each webpage with its target keyword following confirmed URL best practices to create a unique URL. Finally, we have all the final URLs of the new website which are approved by the site owner. Ensure none of the final URLs are non-indexable, blocked by robots.txt file, redirecting, broken, and canonicalized URLs.

Now it's time to build a redirection map. Firstly get all required information i.e. redirection limit or count, 301 or 302 types of redirection, Rule-based or one-to-one redirection prices, redirection method (HTTP method, JavaScript method, refresh, etc.).


After finalizing everything properly map each old URL to its relevant final new URL. If no relevant URL is found then redirect to its relevant parent category. Implement rule-based redirections for URLs

Finally, the low-quality or retired pages, orphan pages, and outdated content pages with less or 0 traffic are forced to write 404 error codes at the server level to slowly remove these legacy URLs from the search index. Along with indexable URLs, we also have existing redirect URLs. To amend the impact of legacy URL redirections replace destination URLs, with relevant new website URLs.


Configure Webmaster Tools, Analytics to Report New Website Changes and Retain the Old Web Analytics Data


After implementing keyword mapping, and redirection mapping, we need to let monitoring tools know our website's changes, to update website search data as required based on trends, insights, customer behavior, etc. We can either use Google Tag Manager/ Telium Tagging to update triggers or independently configure GSC, GA/GA4, Bing Webmaster, Facebook pixel, Adobe Analytics, and other search monitoring tools using the best implementation methods.


Finally, Map your Analytics to Properly Track User Engagements on your Website.


Properly implement web analytics mapping by implementing tracking configuration which provides critical information about how your visitors interact with you, contact you, and make purchases on your websites. For this reason, you must implement GA4 to map out all tracking codes, events, goal objectives, and reports—and make sure they’re all updated to align with the new site.

Here is your Website Migration Checklist (TBH) for implementing Migration as Seamless as Possible


Website Migrations FAQs


How long does it take for indexing and rankings to settle post Migrations?


This is termed "Migration Lag" which ideally should be 3 to 6 months. The SEO migration lag can be based on the extent of website changes made, website change and quality of migration execution. SEOs expect an SEO Dip after implementing migration, which means a drop in rankings, indexing issues etc, This is due to delays in re-crawling, re-indexing of the website by the search engine bots and re-evaluation of the website's relevance and authority by search engines after making amends. I typically advise my clients to monitor the site's performance during the migration lag period, making necessary adjustments and optimizations if needed. As search engines catch up with the changes, the website's rankings and visibility should stabilize and hopefully improve within 7 weeks to 3 months if the migration is well-executed and the new site meets the necessary SEO requirements. I also add that HTTP to HTTPS migration does not lead to any decrease in SEO traffic.


What approach would you recommend if the client wants to change the domain or design?


This answer should depend on why the reason for moving your website, based on my experiences I have suggested client go and follow the approach used for developing the new website from scratch for the new domain, allow it to crawl, make the changes needed for content and website and later build and implement redirection map pointing to relevant new web pages for old/legacy website. This helped one of the luxurious brands regain its rankings and traffic within 3 months after implementing domain change migrations.


What CMS platforms are more difficult or Easy to work with when doing Migrations?


Firstly I never worked for all content management systems and every CMS has limitations. Comparing the ease of use and customised, SEO friendly, available resources to support and security features I would suggest using Wix/WordPress for a website with fewer pages and Adobe Experience Manager or SAP Hybris for enterprise websites of health care, manufacturing business and Salesforce Commerce cloud for e-commerce websites. In the past, I have implemented Single page Applications, Javascript websites and enterprise websites using Salesforce, Adobe Experience Manager, SAP Hybris, Wix, WordPress, Shopify, Magento and Bigcommerce. I have noticed Adobe Experience Manager, Salesforce Hybris and Wix are wonderful CMSs that are easy to customize for meeting business requirements, implement SEO requirements and maintain the website assets etc.,


How Long do redirections are to be maintained to benefit SEO Value after site migrations?


If you are not willing to remove the redirections, it's okay to keep them for long enough. If you want to remove the redirections, i would ask to retain them at least for a year before deciding to remove them. I will always stick to it and recommend my clients to do it as well.
