A new website without losing your Google rankings: the redesign and migration checklist

Why rankings disappear after a redesign, and how to stop it

Rankings drop after a redesign mainly because page addresses change without proper redirects, pages that were bringing in traffic get removed or rewritten, or the new site launches with settings that tell search engines to stay away. To avoid it, list every page that currently earns traffic before the redesign starts, map each old address to its new one, set up permanent server-side redirects, keep the content that ranks, and check the live site carefully in the first days and weeks after launch. Google's own guidance on site moves describes the same core steps.

The typical story is a site that looks great on launch day and loses search traffic within weeks. The design was not the problem. Nobody owned the search side of the project.

Before anyone starts designing: record what you have

The most important work happens before the new site exists. You cannot protect rankings you have not recorded. Export the list of pages that receive clicks from Google Search Console, along with the searches that bring those clicks. Crawl the current site to capture every address, title and description. Note which pages bring in calls and forms, not just visits.

Keep this record somewhere safe and separate from the old website, because once the old site is gone, the information goes with it. It becomes your checklist for the redirect map and your baseline for judging the launch.

• Top pages by clicks and the searches behind them, from Search Console
• A full crawl of every current page address, title and meta description
• Pages that produce calls, forms and bookings
• Pages that other websites link to
• Current tracking setup: analytics, call tracking, form tracking and ad conversion tags

The redirect map is the heart of the project

Google's site move documentation says it is important to map your old site's URLs to the URLs for the new site, and it recommends server-side permanent redirects from the old URLs to the new ones. Its page on redirects explains that 301 and 308 status codes mean a page has permanently moved, and that Google treats a permanent redirect as a signal that the target should be the version shown in results.

In practice, every old page that matters should point to the single new page that best replaces it: the old water heater page to the new water heater page, not to the homepage. Sending everything to the homepage throws away the relevance each page had built. Where a page truly has no replacement, decide deliberately what happens to it rather than leaving it to break.

Google also recommends keeping redirects for as long as possible, generally at least one year, and considering keeping them indefinitely for users. Redirects are cheap to keep and expensive to lose.

Content that should survive the redesign

Redesigns often come with a push to simplify: fewer pages, shorter text, bigger images. Some of that is good. But the pages that rank do so partly because of what they say. If the water heater page that brought in calls is replaced by a single line on a general services page, it will not keep its position, however good the new design looks.

Keep the pages that earn traffic, and keep their substance: the specific services, the areas you serve, the answers to common questions. Improve them if you can, but do not strip them. Carry over page titles and descriptions that were working, or rewrite them carefully. The visual identity can change completely while the content that search engines trust stays in place. A designer colleague has a useful guide on making your website and brand look like one company, which is often the real reason for a redesign; the search work simply has to travel alongside it.

Changing domains or platforms raises the stakes

A redesign on the same domain is the simpler case. Moving to a new domain name, merging two sites or changing platforms adds risk, because every address changes at once. For domain or subdomain changes, Google's site move guidance says to submit a Change of Address in Search Console for the old site, in addition to the redirects.

Google is candid about what to expect. Its documentation says that for medium-sized websites it can take a few weeks or more for Google to gradually start showing the new URLs, and rankings can fluctuate during that time. That is normal. What is not normal is a drop that keeps getting worse, which usually points to redirect or indexing problems that need fixing quickly.

Smaller changes that count as a migration too

Owners often think of a migration as a full rebuild or a new domain name. In practice, any change that alters page addresses carries the same risk, even when the site looks almost the same afterward. Renaming service pages, reorganizing the menu so pages move into new folders, merging several location pages into one, or moving a blog from the main site to a separate subdomain all change addresses that Google has already indexed.

The same is true of changes that happen behind the scenes. Switching hosting companies, moving from one website builder to another, or adding a new booking or e-commerce system can change addresses, remove pages or reset settings without anyone noticing. A business with offices in Dallas and Fort Worth that consolidates two separate websites into one is doing a full migration, whether or not it is called that.

The rule is simple: if any page address will change, the redirect map and the checks in this guide apply. If you are not sure whether addresses will change, ask your developer before the work starts, and ask for a list of old and new addresses before launch rather than after.

Launch day checks

Google recommends preparing the new site and testing it thoroughly before the move, and then testing the redirects once they are live. These are the checks worth running on the day a site goes live, in roughly this order. Most of them take minutes, and each one catches a mistake that can quietly cost a business real traffic.

• The setting that hid the test site from search engines has been removed from the live site
• Every address on the redirect map returns a permanent redirect to the right page
• Internal links on the new site point to the new addresses, not through redirects
• A new sitemap listing the new addresses is submitted in Search Console
• Analytics, call tracking, form tracking and ad conversion tags are firing
• The website link in your Google Business Profile still points to a working page
• Pages load quickly and work properly on a phone

The first eight weeks after launch

Watch Search Console closely for pages reported as not found and for drops in clicks to the pages on your original list. Check the most important searches yourself every week. Look at calls and forms, not only traffic, because a broken form or a missing tracking tag can look like an SEO problem when it is actually a website problem.

Fix problems as you find them rather than waiting for things to settle. A missing redirect found in week one costs very little; the same one found in month four has already cost months of leads. Update the links you control on other sites, such as directories and social profiles, so they point straight to the new addresses. If you are not sure whether a drop is normal fluctuation or a real problem, my guide on how to tell whether your SEO is working explains what to look at.

Who should own the search side of a redesign

Most website designers focus on how the site looks and works, which is exactly what you hired them for. Fewer handle redirect mapping, content preservation and post-launch monitoring as part of the job. Ask directly, before the project starts, who is responsible for each item on the checklists above, and get the answer in writing. If the answer is no one, that is the gap to fill.

Some owners handle it themselves with the checklists above, and for a small site that can work; my guide on whether to do SEO yourself or hire it out helps with that decision. For larger sites, platform changes or domain moves, I recommend bringing in someone who has done migrations before, at the planning stage rather than after launch. If you hire someone for that part, the questions in my guide on choosing an SEO agency and spotting red flags apply here too, especially the ones about who owns the website, the domain and the accounts once the project ends.

Planning a redesign? Start the conversation early

Our one-time website, technical and tracking work is quoted separately from our monthly programs, so a business in Dallas or anywhere else can bring us in for the search side of a redesign alone, whether that means planning before launch or diagnosing a drop after it.

The best time to talk is before the designer finalizes the new site structure, because that is when the redirect map and content plan are easiest to build in. A free thirty-minute strategy call is enough to look at your current site, your plans and the pages that matter most. If the redesign has already launched and traffic has dropped, call sooner rather than later; most of these problems can be fixed, and the earlier they are found, the less they cost.
