What is Full Site Audit?

Comprehensive SEO site audit — one of 2,142 free utilities on this site. It belongs to the Site Audit group inside SEO Tools.

Because everything runs client-side, it also works for confidential material — client drafts, unreleased campaigns, internal data — with nothing transmitted or logged.

How Full Site Audit works

Paste your HTML or content into the input box.
Press Analyze — the checker parses your input in your browser.
Review the pass/warn/fail table and fix the flagged items.

Full Site Audit FAQ

Is Full Site Audit free to use?

Yes. Full Site Audit is completely free with no registration — it runs entirely in your browser as a client-side analyzer.

Does Full Site Audit upload my data to a server?

No. All processing happens locally on your device. Your input never leaves your browser, which makes the tool safe for confidential content.

How accurate are the results?

The tool runs deterministic, transparent logic in your browser. Results are calculated exactly as described and are intended as a helpful starting point — always double-check critical business decisions independently.

What can I paste into this analyzer?

HTML snippets, meta tags, structured data, or page content depending on the tool. Everything is parsed locally — nothing is fetched from the network.

What do PASS, WARN and FAIL mean?

PASS means the check found no issue, WARN flags something to review, and FAIL marks a missing or invalid element you should fix. Each row includes a short explanation.

Is the Full Site Audit suitable for beginners?

Yes — the interface is deliberately plain: labeled inputs, one action button, and a clearly formatted result. No site audit background is required to use it correctly.

Can I use the Full Site Audit on my phone or tablet?

Yes. The page is fully responsive and the tool runs on any modern mobile browser — nothing to install, and since processing is local it works on mobile data just as fast as on Wi-Fi.

What makes the Full Site Audit useful

Tool sprawl is expensive — another SaaS seat, another login, another subscription for a task you do twice a week. The Full Site Audit covers one site audit job completely and costs exactly nothing.

Consistency beats talent. Teams that check their site audit work against a repeatable process ship fewer embarrassing mistakes, and the Full Site Audit is that process, available on every page load.

The honest comparison: enterprise suites give you dashboards you visit weekly; the Full Site Audit gives you answers you need this minute. Both have a role — this one costs nothing and takes zero setup.

Who uses the Full Site Audit?

t => `Pre-launch QA: a final structured pass over a page before it goes live.`
t => `Auditing legacy content — running old ${t.subcategory.toLowerCase()} assets through current standards.`
t => `Routine health checks: a monthly sweep of key pages, recorded and compared over time.`
t => `Teaching: juniors learn standards faster when a table says PASS or FAIL with reasons.`
t => `Post-mortems: checking whether the version you shipped matches the checklist you promised.`

Pro tips for the Full Site Audit

t => `Paste the final rendered version of your content (what users actually see), not the draft with placeholders.`
t => `Analyze a representative sample, not a cherry-picked snippet — the ${t.name} can only report on what you paste into it.`
t => `Fix FAIL rows first, review WARN rows second; PASS rows need no action and exist to confirm what you already did right.`
t => `Use the analyzer before publishing, not after: catching issues pre-launch is a fix, catching them post-launch is an incident.`
t => `Compare two versions of the same page in the ${t.name} to see exactly which checks improved — it is the fastest A/B read you can get.`

Five mistakes this tool prevents

t => `Fixing rows without re-running; unverified fixes have a way of not being fixes at all.`
t => `Ignoring repeated patterns across pages: one page's FAIL is a template, and templates deserve one fix in one place.`
t => `Analyzing a staging page with placeholder content and expecting production-relevant results.`
t => `Pasting partial or truncated markup — the ${t.name} grades exactly what it receives, so incomplete input yields incomplete verdicts.`
