ASHLAR SEO Inspector

Free on-page SEO inspector: titles, headings, links, images, schema, social tags and indexability, analysed locally.

**A fast, honest, on-page SEO check — right in your browser.** ASHLAR SEO Inspector reads the page you're on and shows you exactly what search engines and AI answer engines see. Click the icon, get a scored report across seven tabs. No account, no sign-up, no limits, and nothing leaves your browser. **What it checks** - **Overview** — title and meta description (with character counts), canonical URL, language, charset, viewport, word count, and a clear indexability verdict. - **Checks** — a grouped scorecard of 30+ best-practice checks with a plain- English explanation for each, so you know *why* it matters and how to fix it. - **Headings** — the full H1–H6 outline, with skipped heading levels flagged. - **Links** — internal vs external counts, nofollow/sponsored/ugc, and empty anchor text. - **Images** — alt-text coverage and missing dimensions (a common cause of layout shift). - **Schema** — every JSON-LD block parsed and pretty-printed, with detected Schema.org types and syntax errors surfaced; microdata and RDFa detection. - **Social** — Open Graph and Twitter card tags, with a share-preview. **Indexability, properly checked** — it reads the page's meta robots tag, the `X-Robots-Tag` response header, and your site's `robots.txt`, then tells you in plain terms whether the page can actually be indexed. **Deep links** to Google's Rich Results Test, the Schema.org validator, and PageSpeed Insights — pre-filled with the current URL. **Private by design.** All analysis happens on your device. The extension collects no data, uses no analytics, sets no cookies, and sends nothing to any server. It makes exactly two requests — both to the site you're already on — to read its `robots.txt` and response headers. **Why you should use it** - This tool gives a useful glance at a website to indicate the basic performance of said site, where things are missing and not indexed, and how they can be improved.
