How Do You Migrate a Website Without Losing the Rankings You Have Earned?

The new website launched on a Monday, and at the leadership meeting everyone agreed it finally reflected the size of the company. It had a different design, a different platform and a cleaner menu, with new addresses for every product. The question of what happened to the old addresses never came up, because the old site had already been shut down.

Three weeks later, the sales manager noticed that requests coming from Google had dropped to a fraction of the usual volume. The product pages that brought in the most quotes returned a 404 error to anyone arriving from search, and the links that distributors and industry associations had pointed at the company led to pages that no longer existed. Google began removing the old addresses from its results, and the new ones had not yet taken their place.

Rebuilding the redirect map took weeks of work, and recovering the rankings took months. During that time, buyers searching for those products found the competition first.

A website migrates without losing rankings when every old address permanently redirects to its new equivalent and the content, titles and data Google valued are preserved. All of it is planned before launch.

A migration without a plan erases in one day the history your website built over years

Migrating a website means changing something Google uses to identify its pages. It can be the platform, the URL structure, the domain, the move from HTTP to HTTPS, the merger of two sites or the addition of a second language. A redesign usually includes one of these changes, even when the project was presented as a change of image.

The address of each page: the key Google uses to store its history

Google ranks pages, and each page is identified by its address. That address carries the links other sites have given it, the searches it appears for and the behavior of the people who visit it. When the address changes without notice, the search engine finds a new page with no history and an old page that has disappeared. A permanent redirect is the notice that connects the two and tells Google to transfer what was earned.

That is why the cost of a poorly executed migration is measured in visits and requests. The pages that sell the most are usually the ones with the most history, and they are the first to lose it.

Four mistakes that sink organic traffic after launch

In the migrations we review, the traffic drop usually comes down to one of these four mistakes.

New addresses without redirects: a 404 error as the welcome

This is the most frequent mistake we find and the most expensive one. Anyone arriving from a search result, a bookmarked link or a distributor's website finds an error page and goes back to the search engine to pick another result. Google, for its part, ends up removing those addresses from its results without transferring their history to any new page.

Temporary redirects, redirect chains and redirects to the home page

Some redirects work for the visitor and leave the search engine in doubt. A 301 redirect signals a permanent change; a 302 signals a temporary one, so Google may keep the old address in its results. Chains, where one address leads to another and that one to a third, slow down crawling and raise the risk that a link in the chain fails. Sending every old address to the home page looks like a practical shortcut, and Google treats those addresses as missing pages because the destination has little to do with what the visitor was looking for.

Content cut in the redesign: the pages that ranked disappear

A new design often brings shorter copy, merged product pages and sections removed because "nobody read them." Many of those pages were exactly the ones answering specific searches: the page for a discontinued model that people still look up, a technical guide or an FAQ section. Replacing page titles and main headings with campaign slogans has the same effect, because Google loses the words it associated with each page.

Blocks carried over from the staging site

During development, the staging site is blocked so Google ignores it, with a rule in the robots.txt file or a noindex tag on every page. If that block carries over to the live site, the search engine stops crawling the entire site. The opposite also happens: an open staging site gets indexed and competes with the official site through duplicate content.

All four mistakes have something in common: simple checks before launch prevent them, and fixing them afterward takes weeks of work and months of waiting.

How to keep your rankings: the five-stage migration plan

An inventory of what already works

The plan starts with the complete list of URLs on the current site. It comes from the sitemap, from a crawler that goes through every page and from Google Search Console reports. Each address gets its data: organic visits, the searches that bring traffic, the requests it generates and the external links it receives. In the same stage, you record the current position for the searches that matter most to your business, which will serve as the baseline.

Redirect map: one old address, one new page

The map is a two-column table: the old address and its equivalent on the new site. Every page that stays redirects to its new version with a 301 redirect. Pages that are removed redirect to the closest page in content, such as the category of a discontinued product. Only pages with no visits, no links and no equivalent can return a 410 code, which tells Google the page was retired on purpose.

Content, titles and structured data that move over intact

Pages with history keep their main copy, title, meta description and headings, or improve them without losing the words that already ranked. Image alt text also moves over, along with the structured data that helps Google understand products and FAQs, the canonical tags and, on a bilingual site, the hreflang tags that connect each page to its version in the other language.

Testing on the staging site before opening it

Before launch, a crawler goes through the complete list of old addresses and confirms that each one responds with a single 301 redirect to a page that exists. The same review checks mobile speed, forms, indexing tags and the new sitemap. The staging site stays password-protected for the duration of the test.

Launch and monitoring over the following weeks

On launch day, the redirects go live, the staging blocks are removed and the new sitemap is submitted in Search Console. If the domain changed, Google's change of address tool is also used. Over the following weeks, the team reviews 404 errors, pages excluded from the index and the position of key searches against the baseline. Google recommends keeping redirects active for at least a year, and it makes sense to keep them as long as links still point to the old addresses.

For your sales team, this plan means the pages that bring in quotes today keep bringing them in the day after launch.

What to ask for in writing before you approve the migration

Before you approve the launch of your new website, ask your vendor to answer these questions:

• Who builds the URL inventory, and with which data sources?

• Will you receive the redirect map to review before launch?

• Which tests are run on the staging site, and who approves them?

• Who monitors errors and rankings after launch, and for how long?

• Do you keep access to Search Console, analytics and your domain's DNS?

If any answer stays vague, the risk of the migration falls on your traffic.

At Artisma, the Enterprise package includes the migration and the redirects from your previous website, and both the Essential and Enterprise packages include setup in Google Search Console. Every website ships with baseline SEO (titles, sitemap and metadata), in Spanish and English, tested on mobile, tablet and desktop. We work on your current domain and you keep full control of your DNS.

Frequently Asked Questions

Is it normal for traffic to drop after migrating a website?

A moderate fluctuation during the first weeks is normal, because Google needs to recrawl the pages and process the redirects. What you should watch is the trend. If traffic keeps falling after a few weeks, review 404 errors, redirect chains and pages excluded from the index, and compare them against the inventory you made before launch.

Should I change domains at the same time I redesign the website?

If you can, separate the changes. Each change adds variables, and with several at once it becomes hard to tell which one caused a drop. When a domain change is unavoidable, the redirect map becomes even more important, and it makes sense to keep the old domain registered in your company's name for years.

What happens to the links other websites have to my pages?

Permanent redirects take visitors to the right page and transfer the value of those links. For the most important ones, such as links from distributors, chambers of commerce or industry associations, it pays to ask them to update the link to the new address. That removes a step and protects the link even if your server configuration changes someday.

If your company is planning a redesign or a platform change in the coming months, the time to protect your rankings is before launch. Analyze your website and in under 30 seconds see its speed and whether Google can crawl it correctly, the baseline you will measure your new site against.
