PreflightSEO crawls your old and new environments side by side, compares every URL, and reports every discrepancy before your client ever notices.
A template change noindexes your entire blog. Canonical tags drift in a platform migration. Redirects point to the wrong targets. Google discovers it over weeks. Your traffic report discovers it three months later.
A 10,000-page site has 10,000 failure points. Spot-checking a dozen URLs before launch is optimism, not QA.
Search engines discover errors over weeks. By the time traffic drops appear in GSC, the window to fix the migration cleanly has closed.
Broken link checkers only see the new site. Only PreflightSEO crawls both environments and compares them field by field.
One missed noindex on a staging template once went live and triggered a 40% traffic drop for a client. PreflightSEO was built because of moments like that.
Connect your environments, run the check, act on the report. There is nothing else.
Enter your current and new base URLs. Upload an optional CSV redirect map for precision validation. Set crawl depth and page limits for your project.
PreflightSEO crawls both environments at a polite 1–2 req/sec, normalizes URLs, follows redirects, and compares each page's status, title, H1, canonicals, and meta robots.
Download a prioritized CSV or JSON report. Blockers first — the pages that will vanish from search. Then High, Medium. Fix everything before launch day.
