auditlamp tools // all free

The free
toolbox.

AuditLamp offers fourteen free SEO and AI visibility tools: an AEO checker, a GEO audit, a side-by-side competitor comparison, an AI crawler access checker, an llms.txt generator, a robots.txt generator, a meta tag generator, a canonical checker, a sitemap validator, a redirect checker, a snippet preview, a schema checker, an answer readiness checker, and an embeddable score badge. Every one gives you the full result on screen. No email, no blurred report, no trial clock.

Some tools scan your live site with the same engine that powers the full AuditLamp audit. Others run entirely in your browser and never send us anything. Each card says which.

Fourteen ways to see what the machines see.

site scan / answer surfaces

AEO Checker

Tests whether your pages are eligible for featured snippets and Google AI Overviews, then reports the exact blockers, measured against what Google actually documents, not folklore.

run aeo check ▸
site scan / ai assistants

GEO Audit

Tests whether ChatGPT, Claude and Perplexity can reach, read and cite your site, with a score and the exact blockers, read against documented crawler behavior.

run geo audit ▸
site scan ×2 / competitor

You vs Them

Puts your website next to a competitor's and shows who the machines prefer: overall build score, then SEO, AEO and GEO readiness, tier by tier.

run comparison ▸
site scan / robots.txt

AI Crawler Access Checker

Reads your robots.txt the way GPTBot, ClaudeBot, OAI-SearchBot, PerplexityBot, Google-Extended and CCBot do and shows which AI engines can actually read your site, plus llms.txt and a firewall probe.

check access ▸
site check + in-browser / llms.txt

llms.txt Generator

Check whether your site publishes an llms.txt, then generate a valid one in your browser. It is optional by Google's own docs, and we say so.

generate llms.txt ▸
in-browser / serp preview

Snippet Preview

Paste a title and meta description and see them cut at real pixel widths on Google desktop, mobile, and in an AI citation. Runs in your browser, nothing is sent to us.

preview snippet ▸
in-browser / structured data

Schema Checker

Paste JSON-LD or a whole HTML page. We parse it in your browser, list the @type values, point at syntax errors by line, and flag fake-looking ratings and missing business basics.

check schema ▸
site scan + in-browser / citability

Answer Readiness Checker

Checks whether your page opens with a passage an AI engine could quote standalone, plus a paste-a-paragraph liftability test that runs in the browser.

check readiness ▸
real score / embeddable badge

Score Badge

Build an embeddable badge that shows your real, most recent AuditLamp readiness score with a plain verdict, and links back to your audit. It only renders from a recorded scan, and 404s if you have never run one.

build your badge ▸
in-browser / robots.txt

robots.txt Generator

Build a valid robots.txt in your browser: allow or disallow paths, add your sitemap, and allow or block named AI crawlers on purpose. Honest up front that robots.txt controls crawling, not indexing.

generate robots.txt ▸
in-browser / head tags

Meta Tag Generator

Fill in your title, description, canonical, Open Graph and Twitter fields and copy a complete head block. Live length counts framed as truncation physics, not ranking rules. Runs in your browser.

generate meta tags ▸
site scan + in-browser / canonical

Canonical Checker

Scan a live page or paste its HTML and see whether the canonical is self-referencing, cross-domain, or conflicting. Grounded in Google's Consolidate duplicate URLs guidance.

check canonical ▸
fetch + in-browser / sitemap.xml

Sitemap Validator

Paste your XML sitemap and validate it in your browser: well-formed XML, urlset versus sitemapindex, URL count, missing loc, non-https URLs, the 50,000 URL and 50MB limits, and lastmod format. Honest that Google ignores priority and changefreq.

validate sitemap ▸
trace + in-browser / redirects

Redirect Checker

Trace where a URL lands: the final resolved address and status, http to https upgrades, https to http downgrades, www and trailing-slash changes, and meta-refresh from pasted HTML. Honest about what a browser can and cannot see.

trace redirect ▸
tool questions, answered straight

The honest version.

Are these tools really free?

Yes. No email, no account, no blurred half-report. The site-scan tools use the same engine as the full AuditLamp audit, capped to a single-page free preview. The in-browser tools run entirely on your machine; we could not see what you paste even if we wanted to. We make money on the full audit and its fixes, not on your inbox.

How are these different from the full AuditLamp audit?

Each tool answers one question about one page: can AI crawlers read you, will your snippet truncate, does your schema parse. The full audit runs every documented check across your site at once, ranks what is costing you the most, and tells you what to fix first. Start with a tool, run the full audit when you want the whole picture.

Do I need all fourteen?

No. If you only run one, run the one matching your worry: not showing up in ChatGPT answers, start with the GEO audit; losing the answer box on Google, start with the AEO checker; a competitor outranking you, start with You vs Them.

Do you store the URLs or content I submit?

The in-browser tools (snippet preview, schema checker, the llms.txt generator's editor, the paste-a-paragraph test) send nothing to our servers. The site-scan tools fetch your public pages the way a crawler would; we do not sell scan data or build lists from it.

Will these tools ever tell me to buy something to pass?

No. Every check is grounded in official documentation, and when something is optional we say so plainly. The llms.txt generator, for example, tells you up front that Google does not require llms.txt. An honest "you are fine" is a valid result.

the whole picture

One tool answers one question. The audit answers all of them.

The full AuditLamp audit runs every documented check on your site in one scan: SEO, the answer box, and the AI assistants, ranked by what is costing you customers, in plain language. The diagnosis is on screen in about thirty seconds. No email taken.
