How should we handle an e-commerce platform migration without losing our SEO rankings?

Redirect chains are the most overlooked issue. The legacy URL needs to fire a direct, single-hop 301 to the final destination URL. If you introduce intermediate hops, temporary redirects, or http/https loops that drag things into two- or three-step chains, your crawl budget will tank and pages will fall out of the index.

note: I wrote this based on my own experience, it might not apply to everyone.

We migrated our store pulling 40.000 organic visits six months ago. Our traffic took about a 25% hit over the first three weeks, which was terrifying. But because our redirect mapping was spot on, we bounced back to baseline by week five, and by month two, the faster site speeds actually pushed our traffic past where we started.

Our previous agency forgot to prepare a redirect mapping sheet during our migration and just 301'd a 3.000-page site straight to the homepage. Our revenue evaporated overnight. Cleaning up that mess cost us nearly a year and thousands of lira in consulting fees. Whatever you do, don't leave the URL mapping up to the agency—audit every single row yourself.

Are you changing your category tree and breadcrumb hierarchy during the migration too? If you're purely swapping the underlying CMS and keeping URL paths identical, the risk is minimal. But if you're restructuring the taxonomy from scratch, redirect mapping requires significantly more care.

Make sure to store a static backup of your old site and a full URL list on an external drive before migrating. After going live, you might need to check back through the old site's database to spot any pages with missing redirects.

the biggest mistake is forgetting the images. if your old site gets good traffic from image search, don't mess up the product image filenames and tags on the new site. fyi redirecting image urls helps a ton too.

Migrating with zero traffic loss sounds great in theory but in practice it's impossible. It takes at least 3-4 weeks for the search engine to recrawl 2.500 pages and update the index. Make sure you have a cash flow cushion set aside for the temporary revenue dip during this period.

Urgent launch-day checklist: 1) Make sure the crawl block in your robots.txt file is removed. 2) Check that the security certificate is installed properly. 3) Confirm that your search engine verification codes are in place in the header of the new theme.

There is something to watch out for. Don't hesitate to ask; those who don't ask always pay more.

That's all, sorry if I went on too long.

if you're going this route sort this out first. honestly if you don't wrte this down from the start, it leads to arguments later.

of coures it varies if your situation is different.

I felt relieved reading this answer, so it's not just me. Just because everyone does it doesn't mean it's right.

this is exactly what we experiencd but map listings bring more business than blog posts for most local businesses.

when making a decision first look at what data you have on hand and of course, it varies if your situation is different.

Thanks for writing this, that's the right way. If you get three different answers on a topic the question was asked wrong.

That's all, sorry if I went on too long.

Absolutely. If I were to add anything: Don't trust anyone who gives guarantees; there are no guarantees in this business.

When you try to change everything at once, nothing settles. This is my opinion, I'm not claiming it's absolute truth.

There are three things to check when doing this. Start with a small trial; don't commit to everything at once.

If you post the result here, it will help others too.

I'd appreciate it if you shared the outcome.

If you're going this route, sort this out first. If it's your first time, start small; scaling comes later.

Good luck with that.
