A poorly migrated redesign can wipe out years of SEO in a single day
Let me share one of the most common scares that land on our desk at AMDT. A business redesigns its website, changes domain or platform — everything looks beautiful — and a few weeks later Google traffic plummets. Years of rankings, content, and links, evaporated overnight. Why does it happen? Because migrating a website is not simply moving files: if every technical detail is not taken care of — URLs, redirects, indexing — Google loses track of your site and treats it as if it were brand new. That is far too high a price to pay for a change that should add, not subtract.
SEO Migration
What is an SEO migration, and when do you need one?
An SEO migration is the process of changing something significant about your website — the domain, the design, the platform (CMS), the URL structure, or the switch to HTTPS — while preserving, and even improving, the rankings you already had. Let me explain. You need one whenever you are about to alter the foundations of your site: a redesign, a rebrand and domain change, migrating from PrestaShop to another platform, merging several websites into one… In every one of those cases, doing it without an SEO plan means gambling with your traffic. With a solid plan, however, the migration is transparent to Google and you lose nothing.

The mistake of migrating without anyone controlling the SEO
I have witnessed the same drama far too many times: the migration is handled by the design agency or the technical team — who are good at what they do — but with nobody watching over the SEO. The new website goes live, the redirects are forgotten, URLs change without being mapped, indexing gets blocked by accident… and traffic nosedives. And the worst part is that, by the time someone notices, recovering what was lost costs far more than doing it properly from the start. That is why I always insist: in a migration, SEO is not the last step — it is the one that needs to be there from minute one. Can you see the difference?

How do we handle an SEO migration at AMDT?
With a safety net. Four steps to ensure your website changes without Google — or your customers — noticing anything other than an improvement.
Taking a snapshot before touching anything
Before moving a single file, we carry out a complete inventory of your current website: which URLs rank, how much traffic they bring, which links they receive. That snapshot is your safety net: without it, there is no way to tell whether something has been lost along the way.
Making sure every old page leads to its new one
The heart of a migration. We map every old URL to its new equivalent and set up 301 redirects so that neither Google nor your visitors encounter an error. This way, all the authority each page had earned is transferred to the new one.
Launching with everything checked
We coordinate the launch and verify that everything is in order: redirects working, indexing open where it should be, structured data, mobile version, speed… Nothing is taken for granted; everything is checked before and after pressing the button.
Watching until Google absorbs the change
A migration does not end on launch day. During the following weeks we monitor closely how Google reacts — rankings, indexing, traffic — to detect and correct any issue immediately. Remember our starting premise: people + technology = solutions.

Why trust your migration to AMDT?
Because a migration does not tolerate improvisation, and we have been carrying them out since 2012 without our clients losing what it took them so long to earn.
Agency in Madrid, active since 2012
Over a decade migrating and ranking websites, trusted by organisations such as Autocines, Cofares, and UCI. We have seen (and prevented) many scares.
Technical and White Hat SEO
A migration is pure technical SEO. We carry it out with rigour and without shortcuts, so the change is solid and does not come back to haunt you later.
Without losing your rankings
That is the objective and the yardstick: ensuring that after the migration you retain — or improve — your traffic and your positions. Our entire method is designed for that.
People + technology = solutions
We coordinate with your technical or design team and keep an eye on every detail. Technology helps, but a migration is saved by the judgement of the people involved.
Whether you are changing domain, redesigning your website, or switching platforms, the objective is the same: coming out ahead, not behind.

Frequently asked questions
What is an SEO migration?
It is the process of changing something significant about a website — the domain, the design, the platform, the URL structure, or the switch to HTTPS — while preserving, and even improving, the rankings it already had. The key lies in looking after every technical detail (URLs, redirects, indexing) so Google does not lose track of the site and continues to rank it.
When do I need an SEO migration?
Whenever you are about to alter the foundations of your website: a redesign, a rebrand and domain change, migrating from one platform to another (for example, from PrestaShop), merging several websites into one, or switching to HTTPS. In every one of those cases, doing it without an SEO plan puts your traffic at risk; with a plan, the migration is transparent to Google.
Can I lose rankings when migrating my website?
Yes, and it is the real risk of a poorly executed migration: significant traffic drops that can take months to recover. The good news is that, with proper planning — a pre-migration inventory, URL mapping, 301 redirects, and monitoring — that risk is reduced to a minimum and the migration is carried out without upheaval.
What are 301 redirects and why do they matter so much?
A 301 redirect tells Google and the browser that an old URL has permanently moved to a new one. They are the heart of a migration: done well, they transfer to the new page all the authority the old one had earned; forgotten or done badly, they are the number-one cause of traffic loss after a website change.
Do you work with my technical or design team?
Yes. The usual setup is for the technical or design side to be handled by another team, and we take charge of ensuring all that work is done with SEO in mind: we define the plan, coordinate with them, and validate every step. We do not replace your team; we make sure the migration does not cost you your rankings.
How much does an SEO migration cost?
It depends on the size of the website and the complexity of the change (a redesign is not the same as merging several sites with thousands of URLs). That is why we start with a pre-migration audit that defines the real scope and budget before we begin. The first step, with no obligation, is a conversation to see what your case involves.
