To protect organic traffic during a website migration, record what the old site earns today, map every old URL that has traffic or links to its closest new URL with a permanent 301 redirect, test the new site on a blocked staging copy, remove those blocks on launch day, and check Google Search Console daily for the first month. The most common causes of lost traffic are redirects that are missing or wrong, staging blocks left in place after launch, and ranking pages dropped without anyone checking what they ranked for. Start with one question, because it decides how careful you need to be: will any of your page URLs change? If the answer is no, as with a move to a new hosting provider, the risk is low and most of this checklist is precaution. If the answer is yes, as with a redesign that renames pages, a move from WooCommerce to Shopify or a new domain, every step below matters. This guide is written for business owners and marketing teams in Coimbatore and across India who are about to redesign, replatform or rename their website, and for the developers working with them. If you have not yet chosen who will do the work, read the questions to ask before hiring a web development company first. A website migration is any change that alters where your pages live, how they are built or which domain they sit on, in a way that search engines have to relearn. The risk depends mostly on whether URLs change, because every changed URL needs a redirect and every redirect is a chance for something to break. Platform changes deserve a special note. Shopify uses fixed paths for products and collections, such as /products/ and /collections/, and its migration guide gives a page moving to /pages/shipping-policy as an example of how addresses change. The same guide warns that Shopify's link structure is likely to differ from your previous platform's and tells you to set up redirects for important pages before you move (Shopify Help Center). A WooCommerce store moving to Shopify will change almost every product URL, even if nothing else changes. If you are still deciding between the two, our comparison of Shopify vs WooCommerce for Indian businesses covers the trade-offs. A well-run migration usually costs a short, shallow dip. A badly run one can cost months. The best public data covers domain changes, the riskiest kind. Dan Taylor's study of 892 domain migrations, published by Search Engine Journal in January 2025, found the new domain took an average of 523 days to reach the old domain's organic traffic. 17% of the sites had not recovered after 1,000 days, while the fastest recovered in 19 days (Search Engine Journal). Two caveats matter. Traffic was estimated with third-party tools rather than Search Console, and the sample covers domain changes only, not redesigns on the same domain. Google's own timings are shorter. At Search Central Live in Barcelona on 2 October 2026, Gary Illyes put a typical site move at one to three months, and the slowest at six months to a year or more, according to a third-party recap of his talk (PPC Land). The same recap notes that a small site move can be done in a few weeks. What counts as normal? In a June 2026 Search Engine Journal guide, Sophie Brannon of StudioHawk describes a temporary dip of 10% to 30% as normal in her experience, and a drop of 50% or more as a damaging "migration hangover" (Search Engine Journal). Use those ranges as a rough guide, not a promise, because every site and every move is different. Some migrations are worth waiting for. The safest moment to move is when nothing else important is happening to your traffic. Avoid launching in your peak season. A Tiruppur apparel store should not switch platforms in the weeks before Diwali, and a school should not relaunch its website in admission season. If something breaks, it breaks when you can least afford it. Avoid moving in halves. Google's John Mueller has said that a partial move, where only the homepage moves to a new domain while other pages stay behind, is not seen as a full site move and stays messy until everything has moved (Search Engine Journal, December 2025). If you must move in stages, finish quickly. Avoid changing everything at once if you can help it. A new design, new URLs, new content and a new domain in a single launch make it almost impossible to tell what caused a drop. Where the business allows it, change the platform or domain first and the content later. Most migration problems are prevented, or caused, in the weeks before launch. Work through these nine steps in order. Export at least the last 12 months of Search Console performance data by page and by query, and Google Analytics 4 data on organic landing pages and conversions. Note your top 50 pages by clicks and by leads. This baseline is the only way to prove later what changed, and it disappears from view once the old URLs stop receiving traffic. Build one URL inventory from several sources, because no single source has them all: a full crawl of the site with a tool such as Screaming Frog, every page with clicks in Search Console, landing pages in GA4, the XML sitemap, and pages that other sites link to, from the Links report in Search Console. Include images and PDFs. Coimbatore manufacturers often have product brochures and spec sheets as PDFs that rank on their own and attract links from dealers. In a spreadsheet, put every old URL in one column and the most relevant new URL beside it. A product goes to the same product, a service page to the same service page, a deleted blog post to the closest surviving post or its category. Resist the shortcut of redirecting everything to the homepage. A visitor who clicked a result for a specific product and lands on your homepage usually leaves, and Google learns nothing useful about where that page went. For every page that earns clicks, carry across its title tag, main heading, body content and structured data, unless you have a clear reason to change them. Pages lose rankings when a redesign trims the text that answered the searcher's question. Keep your internal links too. Leadpages found, after moving 1,500 pages in 2026, that a slimmer navigation had quietly removed internal links that pages depended on (Leadpages). Our guide to internal linking for SEO explains why those links matter. Each platform has rules. On Shopify, redirects only work from URLs that no longer load a page, and a store can hold up to 100,000 redirects, or 20 million on Shopify Plus (Shopify Help Center). On WordPress, the permalink setting decides your URL pattern, so set it before you import content, not after. For a site built with a JavaScript framework, confirm that important content and links appear without waiting for scripts; our guide to JavaScript SEO covers the checks. Build the new site on a separate staging address, protected by a password or blocked from indexing. Write down exactly how it is blocked, because every block must be removed at launch. On WordPress, that includes the "Discourage search engines from indexing this site" box, which is easy to forget. Run your redirect map against the staging site and check three things for each old URL: it returns a 301 (or 308) permanent redirect, it reaches the right page, and it gets there in one step. Google treats 301 and 308 as a strong signal that the new URL should be indexed, and 302 and 307 as a weak one. Its crawlers follow up to 10 redirect hops (Google Search Central), but every extra hop is a chance for a chain to break, so point old URLs straight at their final destination. Add your GA4 tag and Google Tag Manager container to every new template, and set up conversions again: form submissions, calls, WhatsApp clicks and orders. Add a GA4 annotation for the launch date. Without this, a migration can look like a traffic drop when the only thing lost was the tracking code. Pick a low-traffic day when your developer and your marketing contact are both available for the following week. If you are also changing hosting, lower your DNS TTL to a few hours at least a week before the move, as Google recommends for site moves without URL changes (Google Search Central). Keep a rollback plan: the old site, backed up and ready to restore, if something serious breaks. On launch day, the order matters more than the speed. Work down this list and do not move on until each line is confirmed. A few details matter here. Google's Change of Address tool is only for moving from one domain to another; it is not for HTTP to HTTPS, www to non-www, or hosting changes, and its effect lasts 180 days (Google Search Console Help). A sitemap file can hold up to 50,000 URLs or 50MB uncompressed, so large stores may need several (Google Search Central). The first 90 days show whether the migration held. Check these things on this schedule, and fix problems on high-traffic pages first. The Crawl Stats report is underused. Glenn Gabe describes a domain change where 4% of Google's crawl requests to the old domain ended in 404 errors instead of redirecting, which pointed straight at the missing redirects (GSQi). In a clean move, almost every request to old URLs should end in a 301. Keep the old domain registered too. Google recommends paying for it for at least a year after a domain change, so nobody else can register it and misuse the traffic it still attracts (Google Search Console Help). Traffic drops after a migration for technical reasons, content reasons and reasons that have nothing to do with the migration at all. Sorting one from another stops you fixing the wrong thing. The technical causes are the easiest to find: missing or temporary redirects, redirect chains, noindex tags or robots.txt blocks left over from staging, canonical tags pointing at old URLs, and slower pages. Google treats redirects and canonical tags as strong signals and sitemaps as a weak one, and asks site owners not to use robots.txt to choose canonical URLs (Google Search Central). When those signals disagree, Google takes longer to settle on your new URLs. The content causes are quieter: pages merged or shortened, headings rewritten, and internal links removed from the menu. The page still exists, but it no longer answers the search it used to rank for. Then there are drops the migration did not cause. Leadpages saw clicks fall 45% year on year between April and July 2026 after its move, but found lost URLs explained only about 3% of the decline. The biggest single drop lined up with a Google core update in June, and AI answers now appeared above results on seven of its ten most important search terms (Leadpages). Their lesson is a useful rule: plot traffic weekly, put a date on each drop, and check it against Google's update history before you blame the migration. A dip that is shallow, spread across many pages and recovering week by week is usually Google recrawling. A drop that is deep, concentrated on specific pages and not improving after four weeks usually has a cause you can find. For a full diagnosis method, see our guide to recovering lost organic traffic, and if new pages are not appearing at all, read why Google is not indexing your website pages. The checklist is the same everywhere, but local businesses have a few extra places where old links live and a few seasons when a migration hurts more. Pump, motor, compressor and textile machinery makers often have product PDFs, dealer pages and export enquiry forms that rank and earn links from distributors. Include every PDF in the URL inventory and redirect each one to its new location. Update the website link on IndiaMART and in export directory listings on launch day, because those are often the pages buyers find first. A move from WooCommerce to Shopify changes almost every product and category URL, so the redirect map is the largest job in the project. Check that size and colour variants, collection filters and old sale pages all have a destination, and avoid launching close to Diwali or Pongal sales. Our comparison of Shopify vs a custom ecommerce website helps if the platform choice is still open. Patients often arrive through Google Maps rather than search results, so update the website link in each Google Business Profile, and check that the appointment booking widget and doctor profile pages move with their URLs intact. A booking form that silently stops sending enquiries costs more than any ranking change. Plan the move for a quiet month, well away from admission season and result days. Keep old admission, fee and course pages redirected for at least a full admission cycle, because parents bookmark them and search for them year after year. Old project pages often keep ranking long after a project sells out. Redirect each one to the developer's current project list or the closest live project rather than deleting it, and keep TNRERA registration details on every project page that moves. Technox Technologies is a web development company in Coimbatore with a dedicated SEO team, so redesigns, Shopify migrations and domain changes can be planned with search in mind from the first week rather than checked after launch. If you are planning a migration and want to know what your current site ranks for before anything changes, start with a free website audit. It gives you the baseline this checklist asks for. It can. A redesign that keeps the same URLs and content usually has little effect. A change that renames pages, switches platform or moves to a new domain can lose traffic if old URLs are not redirected to their new equivalents, or if staging blocks are left in place after launch. Record your current traffic, list every old URL, map each one to its closest new URL with a 301 redirect, keep the content and internal links that rank, test everything on a blocked staging site, remove the blocks at launch, submit a new sitemap, and check Search Console daily for the first month. Some short-term movement is normal; a deep drop that does not recover after a few weeks needs investigating. It depends on the size of the site and the type of move. According to a third-party recap of a talk by Google's Gary Illyes in October 2026, a typical site move takes one to three months to settle, and small moves can take a few weeks. In a 2025 study of 892 domain changes, the average recovery took 523 days, and 17% had not recovered after 1,000 days. Use 301 (or 308) redirects for anything that has moved permanently. Google treats them as a strong signal to index the new URL, while 302 and 307 redirects are treated as temporary and give only a weak signal. Google's site move guidance says to keep them as long as possible, generally at least a year, and its Change of Address help sets 180 days as the minimum for domain changes. In practice, keeping redirects in place permanently costs little and protects links from other sites that will never be updated. No. The Change of Address tool in Search Console is only for moving from one domain to another. For HTTP to HTTPS, www to non-www or a hosting change, redirects and an updated sitemap are enough. Usually not, if URLs stay the same and the new server is fast and reliable. Google notes that crawling often dips right after the move, then rises steadily over the next few days. Lower your DNS TTL a week ahead, keep the old host running until its traffic reaches zero, and watch for server errors, which make Google crawl more slowly. Only if you have to. Changing one thing at a time makes it much easier to see what caused any drop. If both must change together, the redirect map and a careful content check become even more important.What counts as a website migration, and how risky is yours?
