Sukat SEO — On-Page Audit

Audit a page's title, meta, headings, canonical, links, schema and speed in one panel. No uploads, no account.

Sukat SEO is a free, privacy-first on-page SEO audit you run from your browser — and it remembers every scan, so you can track and prove your on-page changes over time. 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. Nine on-page SEO checks, in one panel: - Search snippet — your title and meta description with live character counts, length and pixel-width checks, and a Google-style preview. Both are checked for uniqueness across every page you have audited. - Canonical & indexability — whether the canonical is present, self-referencing, and absolute, plus the page's indexability read live from its robots, X-Robots, and nofollow signals. - 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, the full heading outline, and skipped-level warnings; click any heading to jump to it on the page. - Page content — word count against a thin-content threshold, readability (Flesch reading ease), and target-keyword coverage with the density for each keyword. Audit a selected region instead of the whole page when you need to. - 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. - Page speed — Core Web Vitals measured live in your browser: Largest Contentful Paint, Cumulative Layout Shift, First Contentful Paint, and Time to First Byte, each rated against Google's thresholds. - Structured data — JSON-LD entities validated against Google's rich-result requirements, with missing required and recommended properties named and malformed blocks surfaced. Track every change over time. Sukat SEO saves each scan, so every check keeps a version history. Compare any two versions to see exactly what changed, what got resolved, and what is new — a title rewrite, a canonical fix, a heading you dropped, keyword coverage drifting, or a page quietly slipping into noindex. Export any comparison as a clean before/after image with one click ("Copy diff") and drop it straight into a client report or email. 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. 4. Re-scan any time — compare versions to see what changed, and copy the diff to share it. 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 history is stored 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.
