Technical SEO FAQ · Redirects, Status Codes, Sitemaps & Robots
What would you check after a large-scale URL migration?
Check:
- old URLs return correct redirects;
- redirects point directly to final URLs;
- new URLs return 200;
- canonicals point to new URLs;
- internal links use new URLs;
- XML sitemaps contain new URLs;
- robots.txt doesn't block new URLs;
- hreflang references are updated;
- structured data uses correct URLs;
- Search Console reports are monitored.
Google recommends preparing a URL mapping, implementing redirects, testing before launch and monitoring after migration.
