Hi PH I built Seoxpert because I shipped a deploy in February that added noindex to a third of my pages. Caught it 11 days later when Search Console finally surfaced it. Traffic was already gone for two weeks. The question I kept asking: why don't I have a CI step that crawls my site after every deploy and tells me what broke? That's what Seoxpert does. After every deploy (manual, scheduled, or fired by webhook from Vercel, Netlify, or any CI), it crawls your whole site and surfaces: SEO regressions: noindex flips, broken internal links, dead CTAs, missing meta tags, canonical bugs, 404s on previously-working pages Content drift: AI-generated patterns, GEO and AI-citation readiness, thin or duplicate pages, missing answer-first structure on question pages Security: HTTPS gaps, CSP misconfigurations, mixed content, exposed endpoints, the classic "staging robots.txt accidentally promoted to prod" Performance: Core Web Vitals against Google's thresholds, render-blocking scripts, slow TTFB, oversized images Every finding includes : - severity - affected pages - who should fix it (developer, content editor, SEO specialist, or business owner) - a copy-paste fix or developer-handoff message. A few things I'm happy with: - Diff view that compares this scan to the last and tells you what regressed in plain English - White-label PDF reports for agencies (your logo, your colour, no Seoxpert branding) - Per-domain deploy webhooks so a curl from your CI is enough wiring A few things I'm still not happy with: - JS-heavy SPAs render via a Playwright fallback. It works but it's slower than I'd like. - The catalog of issue explainers is auto-generated, then hand-edited. Some of the older entries are still rough. - I don't do backlinks or keyword research. Different tool, different problem. Pair it with Ahrefs or Semrush if that's what you need. About the free tier, since I know PH cares about this: - 4 full scans a month, forever, no card - One domain (yours) - Every check category active. Not a stripped version. Same SEO, security, performance, - content, GDPR, AI-content checks the paid plans run. - You can schedule those 4 scans on a weekly cadence so it's set-and-forget for your main site - PDF and CSV exports work - What you don't get on free: API tokens, white-label branding, client portals, more than one domain If you're a solo founder or small team monitoring one main site, free covers the workflow. If you're an agency or have multiple properties, that's what Pro and Agency are for. Try it on whatever site you can find a regression on, and tell me in the comments what you found. The stupider the regression, the better the story.
