SerpCraft

SEO Release Diff

Compare two URLs and catch SEO regressions before you ship. Evidence-first reports — no scores, just what changed, why it matters, and how to fix it.

Both URLs must be publicly accessible (no auth/firewall). Max 10s timeout per URL.

Staging vs Production

Catch noindex, canonical, redirect issues before deploy

Migration Guard

Old URL → New URL: verify 301s, canonicals, indexability

Regression Watch

Save baseline, compare later, get notified on changes
