Site Migrations & Redesigns

๐Ÿšš
The night before the new site launch
"Launching tomorrow! New design, new URLs, new domain. Everything's great!"
๐Ÿ˜ฐ
One week later
"Traffic dropped 70%. All old URLs return 404. Customers can't find us on Google. What happened?!"
โš ๏ธ Site migration โ€” one of the riskiest SEO operations. Without proper preparation you can lose all accumulated organic traffic. With proper preparation โ€” nearly no losses at all.

GSC + monitoring
Notify Google, watch for 4 weeks
Post-launch monitoring:

โ˜ GSC Coverage: no mass 404 errors
โ˜ GSC Performance: traffic shouldn't drop
โ˜ New URL indexing in GSC
โ˜ All redirects working correctly
โ˜ Internal links updated (no extra hops)
โ˜ Backlinks from external sites โ€” request updates
๐ŸŽฏ Golden migration rule: launch during off-hours (night/weekend), have a rollback plan, and never do two large migrations at once.
๐ŸŽฎ Test yourself: put the site migration steps in the correct order!
