Sukat SEO — On-Page Audit

On-page SEO audit in one panel: score a page's title, meta, canonical, headings, links, images and schema, with what to fix.

Sukat SEO is a free, privacy-first on-page SEO audit you run from your browser. Open the side panel on any page, click Scan this page, and get a clear score plus exactly what to fix — no account, no uploads, and nothing sent to a server. Eight on-page SEO checks, in one panel: - Title tag — length, pixel width, and whether it is unique across the pages you have audited. - Meta description — length and uniqueness, with live character counts. - Canonical — present, self-referencing, and indexable, read live from the page's robots meta. - Open Graph & Twitter cards — preview how the page looks shared on Facebook, LinkedIn, and X, with og:image dimension and aspect-ratio checks. - Heading structure — H1–H6 counts and skipped-level warnings; click any heading to jump to it on the page. - Links — internal, external, broken, and redirected links checked live, with anchor text, and click to locate each one on the page. - Images — missing or empty alt text and oversized images, with thumbnails; decorative images are recognised so they are not falsely flagged. - Structured data — JSON-LD entities validated against Google's rich-result requirements, with missing required and recommended properties named and malformed blocks surfaced. A score for every page. Each page gets a 0–100 score and a grade, and a per-site board remembers every page you have audited and floats the lowest-scoring pages to the top — so you always know what to work on next. Export the full audit as CSV or JSON. How it works: 1. Click the Sukat SEO icon to open the side panel. 2. Click Scan this page. 3. Read the score, expand any check, and click a link, heading, or image to locate it on the page. Privacy: Sukat SEO reads a page only when you scan it. To check links and read the sitemap it requests those URLs from your browser, the same way a visitor would — nothing is ever sent to a Sukat server. No account, no ads, no analytics, no tracking. Audit results are cached on your device so revisiting a page is instant. Works on any http(s) page in Chrome and Chromium browsers (Edge, Brave, Arc, Vivaldi). Part of the Sukat tool family: Sukat compresses images to an exact size, Inspector audits a page's images, Crawler audits the crawl layer (sitemap, robots.txt, llms.txt), and DocMatch checks a document against the live page. One privacy model — everything runs in your browser.
