Free Technical SEO Audit for Pages & Small Sites

Yes. There is no paid tier. URL Audit and Full Site Crawl carry sensible fair-use rate limits so the service stays sustainable for everyone, without an artificial cap on normal indie-site sizes.

No. There is no account, login, or email requirement to use this tool.

URL Audit includes a visible PageSpeed performance check by default, and you can disable it before you audit. After Full Site Crawl, PageSpeed is optional and manual, and tests the resolved homepage only—not every crawled page. PageSpeed is a separate external lab measurement and never affects SEO Launch Readiness, its verdict, findings, coverage, confidence, cooldown, or Changed Pages allowance.

URL Audit checks one page. Full Site Crawl audits up to 100 public pages per run, starting from the site's origin and following internal links and the sitemap. If your site has more than 100 pages, the report is honestly marked as partial coverage rather than presented as a complete site verdict.

URL Audit checks fetch and HTTP state, indexability directives, canonical states, missing titles and descriptions, missing H1s, document language, internal links, missing image alt attributes, and JSON-LD syntax. Full Site Crawl adds robots.txt, sitemap, duplicate metadata, link-destination, and discovery checks. Rendered-DOM checks are identified separately as Chrome extension Current Page capabilities.

No. It checks deterministic technical and on-page conditions it can independently verify by fetching your page — it does not read Search Console, Google Analytics, or any ranking data, and it doesn't guarantee rankings, traffic, or how or when Google crawls and indexes a page.

There is a 0-100 Launch Readiness Score, but it always comes with a plain verdict and every individual finding behind it, each with evidence and a fix — never a bare number with nothing to act on. It is not a Google ranking score.

URL Audit checks exactly one page you paste in. Full Site Crawl discovers and audits up to 100 pages starting from the site's origin, so it can also catch site-wide issues — like duplicate titles across pages or a blocked robots.txt — that a single-page audit structurally can't see.

Yes — this is the tool's strongest workflow. After you deploy, give it up to 20 exact URLs and it rechecks only those, with no discovery crawl of the rest of the site, and merges successful results into your saved site baseline.

The extension inspects the actual rendered page in your browser tab, entirely locally. A website can't do that for a URL you paste in, so URL Audit fetches the page through the audit service instead. Checks that depend on rendered, client-side-only DOM state are honestly marked "could not verify," never faked.

The audit reads the HTML actually returned by the server, not content injected later by client-side JavaScript. For a mostly server-rendered page this covers nearly everything that matters for SEO; for a heavily client-rendered app, meaningful content added after load may not be visible to this audit — or to search engines that don't execute JavaScript either. The Chrome extension's Current Page mode can see the fully rendered DOM instead.

No. It checks deterministic technical and on-page conditions within your control before you publish. It cannot guarantee search rankings, traffic, or how or when Google crawls and indexes a page.

No. Saved audits, comparisons, the Changed Pages baseline, and successful PageSpeed companion results are stored locally in your browser (IndexedDB). SEO audit URLs go to our audit service; when PageSpeed is enabled or manually started, our backend also sends that selected public page URL to Google PageSpeed Insights. See the privacy policy for full details.

Yes. SEO Launch Auditor is also a Chrome extension that can audit your current tab entirely inside your browser, with no fetch required, and shares the same scoring engine and audit service as this web tool.
