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. 👉 Try it without signing up: https://pagesignal.alorenzom.com... 👉 Free tier on RapidAPI: https://rapidapi.com/AlbaLM/api/... I'd love your feedback: which check is missing for your use case? I'm shipping updates based on what you tell me today 🙏
