eCommerce replatforming is not a one-click affair at all, but if you have managed to transfer all the store entities and failed to consider the post-migration activities, you are almost certain to take a major hit in the overall performance of the e-store. Take time to go through the following checklist to prepare yourself from unexpected disasters in the form of broken SEO or corrupted data.
Perform post-migration audit
Even if you’ve gone through the migration procedure seamlessly and error-free, take time to check whether all of the data has been imported to the new platform correctly, and ensure demo migration results were successful. Make sure the domain name is active, and the navigational links are working as they should. When done, go to the frontend to see if the products are visible in catalogs, and onsite search is working. Look through links in menus, header, footer, and inside the pages. For a comprehensive review, consider using our Migration Preview Service, or download our Universal eCommerce Migration Checklist.
Take Care About SEO
When your eCommerce migration is done, SEO indicators should be the first thing to evaluate. To be more specific, take time to perform the following steps: 
Set 301 redirect
This step allows to direct customers and search engines to your new store and keep site positions. Make sure that “nofollow” and “index, follow” tags are on the expected pages. Don’t forget to search for 404 pages that aren’t supposed to be there. Verify the status of the internal links and ensure there are no broken ones. For detailed guidance on SEO preservation, check our SEO migration guide. Next, you should check the website for duplicate content, title tags, meta descriptions, header usage, image attributes, etc.
Look for 404
Consider creating the necessary ones from scratch (like About us page) if needed, and creating a custom 404 page for the pages you no longer need. This page should include a link to the main page of your new site, a link to the site map with all the pages of your store, navigational aids (drop-down menus, search engine boxes).
Generate sitemap
This step helps to inform search engines about pages to index. Almost all modern shopping carts can generate the sitemap automatically. For more advanced SEO strategies, consider integrating new SEO URL options. Resubmit your XML sitemap to Google Search Console to have your newly migrated site reindexed.

Monthly Update – March 2026
As we move further into 2026, a critical trend for any successfully migrated eCommerce store is the absolute necessity of mobile-first optimization. Google's mobile-first indexing has been a standard for years, and its impact on search rankings and user experience continues to grow. Ensuring your newly replatformed store offers a seamless, fast, and intuitive experience across all mobile devices is paramount. This includes responsive design, optimized image loading, streamlined checkout processes, and easily navigable menus. A poor mobile experience can drastically increase bounce rates and negatively affect conversions, undoing much of the benefit of a modern platform. Beyond mobile, embracing a truly omnichannel strategy is key. Customers interact with brands across multiple touchpoints—web, mobile app, social media, physical stores, and even voice assistants. Your post-migration focus should extend to integrating these channels, providing a consistent brand experience, and leveraging data from each interaction to personalize the customer journey. Tools for unified inventory management, CRM integration, and customer service across channels are no longer just "nice-to-haves" but essential components for sustained growth and competitive advantage in today's dynamic digital retail landscape. Prioritize a comprehensive review of your mobile performance and begin building out robust omnichannel capabilities to maximize your new platform's potential.
