Website relaunch without SEO losses: the checklist
An unplanned relaunch can destroy years of ranking work. This checklist shows how traffic and visibility survive the move intact.
The classic relaunch accident goes like this: the new website goes live, everyone celebrates the design — and four weeks later organic traffic has collapsed by 60 percent. Google can’t find the old pages anymore and doesn’t know the new ones yet. The insidious part: the damage only shows with a delay, when the project budget is long spent.
Before the relaunch: take inventory
- Capture all indexed URLs — via Google Search Console and a crawling tool. You can only redirect what you know about.
- Identify your top pages: which URLs bring traffic, rankings, backlinks? These pages are your capital and deserve special care.
- Document existing rankings so you can compare after the relaunch instead of guessing.
During the relaunch: the non-negotiables
- 301 redirects for every old URL to its new counterpart — individually, not wholesale to the homepage. The blanket redirect is the most common and most expensive mistake.
- Carry over title tags and meta descriptions or improve them deliberately — don’t let the CMS regenerate them.
- Check internal links: no links to old URLs, no redirect chains.
- Resubmit your sitemap.xml and watch Search Console for crawl errors.
After the relaunch: two weeks on watch
The first 14 days decide everything. Check Search Console daily for 404 errors and indexing issues. Individual ranking fluctuations are normal and settle down; wholesale ranking losses on important pages are an alarm signal — and still fixable now, while Google hasn’t forgotten the old signals.
A properly planned relaunch loses no rankings. In most of our projects, visibility actually increases — because the new website is faster, better structured and technically cleaner than the old one.
