PageSignal
SEO, metadata & JSON-LD audit for any URL in one API call
PageSignal turns any public URL into a clean JSON SEO report in a single request: title & meta checks, Open Graph/Twitter tags, indexability, canonical, robots.txt & sitemap, validated JSON-LD, headings, image ALT coverage and links. Every point of the 0–100 score comes with a reason, so you can show users exactly what to fix. Built for SEO monitors, CMS pre-publish checks, agency reports and AI agents. Free tier on RapidAPI.
Hi Product Hunt 👋 I'm Alba, the maker of PageSignal.
Why I built it: every time I needed to check a page's SEO from code — for a monitor, a CMS pre-publish check or a quick client report — I ended up gluing together a scraper, an Open Graph parser, a JSON-LD validator and a pile of if-statements for canonical and robots rules. And the result was always a number with no explanation. [Añade aquí tu momento concreto: qué proyecto o cliente te hizo decir «basta».]
So PageSignal does all of it in one request:
• Title & meta description checks (length, duplicates)
• Open Graph / Twitter tags, and which recommended ones are missing
• Indexability: meta robots + googlebot + X-Robots-Tag combined into one verdict
• Canonical, robots.txt and XML sitemap discovery
• Every JSON-LD block parsed and validated
• A 0–100 score where every rule shows its points, severity and the reason
A few things I cared about:
🔍 Explainable, not magic — you can show your own users exactly why a page scored 68.
⚖️ Fair billing — if the target site blocks bots, times out or is down, you get a 5xx and it doesn't count against your quota.
🛡️ Safe by design — strict SSRF protection, size/time limits and honest diagnostics (it tells you when a page is JavaScript-rendered and the result shouldn't be trusted blindly).
Honest limitation: it doesn't execute JavaScript, so SPAs may return partial data — the response flags it.

I'd love your feedback: which check is missing for your use case? I'm shipping updates based on what you tell me today 🙏
