SEO migration and recovery
A new website is one of the fastest ways to lose your Google traffic. We guide your migration so your rankings move with you: a complete redirect plan, checks before and after launch and monitoring until traffic is stable. If traffic has already dropped, we find the cause and recover what can still be saved.

Sound familiar?
Since the new website our organic traffic is down by a third.
Old pages that used to bring leads now return a 404.
Everything redirects to the homepage and nobody knows which URL used to be what.
We want to switch CMS or domain, but we are afraid of losing everything.
The web agency says SEO was not part of the job.
How we help
We treat a migration as a move with an inventory: every URL that brings traffic, links or leads gets a new destination, every redirect is tested and we compare traffic before and after. So at every moment you know whether the move is working.
Why Customer Impact
From Search Console, your analytics and your backlinks we pull the URLs that really count. That list is the basis of the redirect plan, not the sitemap of the new site.
Every old page goes to the most equivalent new page, with a permanent 301 redirect. No mass redirects to the homepage and no redirect chains.
On the staging site we check redirects, canonicals, robots rules, metadata and internal links. What is wrong there will be wrong live too.
After launch we compare clicks, impressions and indexing with the period before and step in where a page drops.
About Customer Impact
Customer Impact is a digital marketing agency founded by Tanguy De Keyzer. For more than 10 years we have been building the growth engine of startups, scale-ups and established companies.
At Customer Impact, SEO, websites and measurement are one team. We see migrations from both sides: as builders of new sites and as the team that has to win back the traffic afterwards. We use that experience to make your move safe.
What we stand for:
What we do
A snapshot of your traffic, rankings and backlinks, so you can compare objectively afterwards.
A complete mapping from old to new URLs, with 301 redirects and no chains.
Status codes, canonicals, robots, metadata and internal links checked before the site goes live.
Guidance for a new domain, a new CMS or a move to https, including the Change of Address in Search Console.
Before and after comparison per page, follow-up of 404 errors and indexing.
If traffic has already dropped, we look for the cause in redirects, content and technical setup and recover what can still be saved.
Our process
We record today's traffic, rankings and backlinks and list every URL that matters.
Every old URL gets a new destination, agreed with your web developer in a single file.
Redirects, canonicals, robots, metadata, structured data and internal links are tested before launch.
We check the redirects live, submit the sitemap and use the Change of Address tool for a domain change.
We compare traffic before and after and fix pages or redirects that fall short.
Always all-in
With a new website, a new CMS or a new domain, hundreds of URLs often change at once. Google has spent years getting to know your old pages. If they disappear without a clear new destination, Google almost starts over. We see the result at many companies: a beautiful new site and a traffic curve that bends downwards on launch day.
An SEO migration prevents that. We take an inventory of what your old site is worth, set a new destination for every URL and check everything before and after launch. You can read the full approach in our guide on website migration without losing rankings.
For a site move Google recommends mapping old URLs to new ones and using permanent redirects, and keeping those redirects for at least a year. What a 301 redirect does exactly, and why a redirect to the homepage is no solution, we explain in the 301 redirect plan and redirect chains.
If your domain name changes too, we use the Change of Address tool in Search Console. See also migrating a domain without downtime and our CMS migration guide.
Want to see first how your old URLs are doing today? With our free redirect checker, you see the status code and final destination per URL.
If your site is already live and traffic has dropped, the work starts with the cause. We compare the period before and after per page in Search Console, find which old URLs lost traffic and check redirects, content and technical setup. How to start that analysis yourself, read in analysing a website traffic drop. And do not forget your local listings: your Google Business Profile when a new website goes live.
For companies planning a new website, a new CMS or a new domain, and for anyone who lost traffic after a relaunch. If we build your new site ourselves through website development, the migration is included as standard. If you work with another web agency, we work alongside them. After the migration you can move on to our SEO service.
Contact us and within 24 hours you hear how we would approach your migration.
In almost every failed migration we see, the new site was beautiful and fast, but nobody had a list of what the old site did. The redirects did not exist or all went to the homepage. Whoever takes inventory first moves their rankings with them.

What to expect
Week 1
We record what ranks today and which URLs bring in links and leads.
Week 2 to 3
The plan and the SEO requirements go to your web developer, so they are in the new template.
Before launch
We test everything that can break at launch and hand over a list of what still needs doing.
Launch and week 1
Redirects, sitemap, indexing and any change of address, checked on the day itself.
Month 1 to 3
Fluctuations are normal; we follow up per page until traffic has stabilised.
Case studies
We rebuilt the website of a Belgian B2B service company in Astro: fast, light and readable for Google and AI agents, with the SEO foundation in the template from day one. After the rebuild, clicks and impressions in Google grew month after month.

Briefly tell us what it is about. You get a personal reply from Tanguy or someone from the team, not a call centre.
We work on request, because every migration is different. What drives the effort: the number of URLs with traffic or backlinks, whether the domain or the CMS also changes, whether the URL structure changes, the number of languages and whether the migration has already happened and needs recovery. After a short intake you get a proposal with a clear scope.
As long as possible. Google recommends keeping redirects for at least a year, and for visitors and old links it is better never to remove them.
A temporary fluctuation is normal; Google itself says visibility can fluctuate during a move and settles afterwards. A drop that persists after a few weeks almost always points to missing or wrong redirects, lost content or technical blocks.
Often yes, especially if the old URLs can still be traced from Search Console, an old sitemap or the Web Archive. We find which pages lost traffic, add the missing redirects after all and restore content that disappeared in the rebuild.
No. Google usually treats redirecting an old page to the homepage as a page that has gone. Every old URL should go to the most equivalent new page.
Then extra steps come in: domain-level redirects, the Change of Address tool in Search Console and updating your Google Business Profile, listings and ads. We include them in the plan.
Test your old URLs with our free redirect checker. You see the status code per URL, the final destination and whether there is a redirect chain.
