SEO Inspector
Paste any page URL to inspect its SEO: meta tags, social previews, structured data, headings, links and HTTP response — all in one detailed report.
The SEO Inspector fetches a page the way a search-engine crawler would and lays out every on-page signal that affects ranking and click-through: the title tag and meta description with their pixel-budget lengths, the canonical URL, meta robots and X-Robots-Tag directives, the HTML lang attribute, viewport and charset.
It parses Open Graph and Twitter Card tags so you can preview how a link looks when shared, validates schema.org structured data (JSON-LD, microdata and RDFa) and lists the detected types, builds the full H1–H6 heading outline, counts internal, external and nofollow links, flags images without alt text, and reads robots.txt for crawl directives and sitemap declarations.
Everything is summarised into a single on-page SEO score with a pass / warning / fail checklist, so you can quickly audit your own pages or inspect a competitor. Nothing is stored — each report is generated live from the current response.
How to use it
- Paste a page URL and press Inspect. The server fetches it the way a search crawler does — without running JavaScript.
- Read the report blocks: title and description with character counts, canonical and robots, Open Graph and Twitter Card with a preview, schema.org data, the H1–H6 outline, links, and images without alt text.
- The overall score and checklist highlight what to fix first: a missing description, several H1s, images without alt, a wrong canonical.
When it helps
- Before publishing a page: make sure meta tags and social previews are filled in and not truncated.
- Auditing another site: see how a competitor structures headings and which structured data they use.
- Finding why a page is not indexed: spot an accidental noindex, a canonical pointing elsewhere or a robots.txt block.
Frequently asked questions
Why does the inspector not see content that is on the page?
It reads the raw HTML without executing JavaScript. If content is loaded by a script, search engines will not see it immediately either — a reason to consider server-side rendering.
How long should title and description be?
Title up to 60–65 characters, description 120–160. Longer text is truncated in results, though keywords at the start still count.
Does a score of 100 guarantee high rankings?
No. The score reflects technical hygiene. Rankings depend on content quality, links and user behaviour — but without the basics they have nothing to stand on.
