Website migration: Step-by-step website transfer guide: a practical guide to website migration, with FAQ, chart, useful links and checklists for you
The website migration is the process by which a site changes essential elements of its presence: platform, domain, URL structure, server, protocol, design, information architecture or a combination of these. For an e-shop, however, the transition is not just a technical task involving developers. It directly affects the SEO, revenue, analytics data, shopping experience, brand credibility, and Google's ability to re-understand which products, categories, and pages deserve to appear in organic results.
Semrush's article on website migration checklist provides a clear basis: before making any changes, it is necessary to record the existing situation, crawl the site, benchmark the rankings, map the URLs, correct redirects, check indexability, update the sitemap and systematically monitor after the launch. For e-shop owners, these steps are not «details” SEO». It is the way to reduce the risk of losing the pages that bring in orders: categories with commercial intent, products with backlinks, landing pages from campaigns and articles that feed the funnel.
For better organic performance, the topic website migration it needs a clear structure, specific answers and practical check points. The following outline helps to quickly see which factors are most important to the reader and for evaluating the content.
Indicative TWO DOTS mapping for the structure of the topic
A site migration can involve moving from WooCommerce to Shopify, from a custom CMS to Magento or Shopify Plus, changing a domain after a rebranding, redesigning with a new URL structure, merging two e-shops into one, moving to a headless architecture, or changing from HTTP to HTTPS. In all of these cases, the common denominator is that Google has to reread, re-correlate, and re-evaluate the content. If the migration is done without an SEO migration plan, the effects usually appear within the first few days or weeks: a drop in organic traffic, loss of visibility in categories, 404 errors, incorrect canonical tags, duplicate content, problematic filters, lost structured data, and inability to measure conversions.
On a corporate website with 30 pages, migration can be controlled relatively easily. On an e-shop with thousands of products, dozens of categories, faceted navigation, filters, product variations, out-of-stock URLs, pagination and dynamic parameters, the environment is much more complex. Ecommerce migration requires you to know which pages generate revenue, which ones bring organic traffic, which ones have backlinks and which ones should not be migrated because they create crawl waste or thin content.
The first major risk is the loss of rankings. If a category that is on the first page of Google is moved to a new URL without a proper 301 redirect, the equity that was built through content, internal links and backlinks can be weakened. The second risk is the loss of conversion data. If tracking in GA4, Google Ads, Meta Ads or merchant feeds is not transferred correctly, the owner sees sales but does not know where they came from. The third risk is the user experience: checkout bugs, slow pages, non-functional filters and changes in product availability can reduce the conversion rate even if traffic remains stable.
The importance of rankings is clearly seen in Backlinko’s data on organic CTR. The first position in organic results receives an average of 27.6% of clicks, while the following positions have significantly lower performance. So, a drop from first to third or fourth position after a bad website migration is not just a «small fluctuation». It can translate into a noticeable decrease in orders.
The fourth risk concerns checkout and trust. According to the Baymard Institute, the average cart abandonment rate in e-commerce environments is 70.19%. This means that even before a migration, the majority of users abandon their cart. If technical obstacles, slow pages, or inconsistencies in pricing and availability are added after the migration, the e-shop can lose sales without being immediately noticed by the users. SEO reports.
A proper website migration checklist starts weeks before launch and continues for quite some time after. The basic principle is simple: don’t change anything that you haven’t measured first. For the e-shop owner, this means that before giving the final «yes» to the migration, there must be clear data on organic traffic, rankings, revenue per landing page, backlinks, top categories, crawl errors, and the technical status of the site.
Step 1: Define the type of migration and goals. A domain migration is one thing, a platform change is another, and a complete redesign with a new information architecture is another. List what is changing: domain, URLs, templates, CMS, server, languages, checkout, filters, internal linking, structured data, blog, hreflang, pagination, and product feeds. The goal shouldn’t just be to «get the new site up and running,» but to maintain or improve the SEO performance, speed, measurement and conversion rate.
Step 2: Do a full technical SEO audit on the existing site. Use a crawler to extract all indexable URLs, status codes, titles, meta descriptions, canonical tags, headings, internal links, images, structured data and hreflang where available. Combine the data with Google Search Console, GA4, backlink tools and export from the e-commerce platform. The logic is to separate the pages that have real value: high traffic categories, products with sales, URLs with backlinks, blog posts that bring assisted conversions and landing pages that support paid campaigns.
Step 3: Create URL mapping. URL mapping is the heart of e-shop migration. Each old URL should have a clear destination: a corresponding new URL, a closest related category, an alternative product, or, if there is no reason to keep it, an appropriate status. For commercial URLs, 301 redirects are critical. Avoid redirect chains, mass redirects of all old pages to the original, and redirect loops. For discontinued products, consider whether they should lead to an equivalent product, a parent category, or an updated page with related suggestions.
Step 4: Set up a staging environment that is not indexable. Staging should be password protected or IP restricted and properly blocked from search engines. Here you check templates, canonical tags, robots.txt, XML sitemap, pagination, filters, breadcrumbs, product schema, category copy, internal links and mobile rendering. Be careful: a wrong robots.txt on the live site can cut off Google's access to your most important pages. Similarly, wrong canonicals to staging URLs can create serious indexation problems.
Step 5: Measure Core Web Vitals and Speed Before Transitioning. Redesigns often add heavy scripts, sliders, tracking pixels, apps, and third-party tools that weigh on performance. For e-shops, speed affects both SEO and conversions. Google data shows that as loading time on mobile increases, the likelihood of abandonment increases. Therefore, before approving the launch, the new site should be compared to the old one on real pages: homepage, category, product, cart, and checkout.
If you are planning a website migration for a professional site or e-shop, TWO DOTS can connect the transition with a complete SEO strategy, correct website construction and safe e-shop construction, so that switching platforms doesn't cost organic visibility or sales.
Before you hit the migrate button, create a migration control sheet with owners, deadlines, and status of each task. Confirm that all important URLs have been mapped, that 301 redirects have been tested in staging or pre-production, that the XML sitemap only includes canonical indexable URLs, and that robots.txt doesn’t block critical resources like CSS, JavaScript, or product paths. Also, check that category pages have unique titles, meta descriptions, and useful content, as category copy that was worked on for SEO is often lost in migration.
On launch day, avoid Fridays and high-traffic periods such as Black Friday, sales or large seasonal campaigns. The transition should be done in a time window where the team can review, fix and monitor without pressure. Immediately after go-live, crawl the new site and check status codes, redirects, canonical tags, noindex, sitemap, robots.txt and basic templates. Manually test the purchase flow: product search, filters, variant selection, add to cart, coupon, checkout, payment, confirmation email.
