SEO audit tool for Google and AI answers.

An SEO audit tool is software that crawls a website, checks every page it reaches against a catalogue of known technical, content and user experience problems, and ranks what it finds by severity. RankX AI’s website audit runs 48 checks, scores the whole crawl from 0 to 100, and turns the fixes into tracked tasks.

RankX AI’s website audit runs 48 checks in three groups. 18 content checks read titles, meta descriptions, headings, thin or duplicate content and image alt text. 25 technical SEO checks cover broken links, redirect chains, canonical tags, noindex pages, the XML sitemap, robots.txt, HTTPS and page weight. 5 user experience checks cover server response time, layout shift, render-blocking resources, a custom 404 page and structured data. A full crawl also runs a Lighthouse lab check of the homepage on mobile and desktop.

A traditional SEO audit reads your site the way Googlebot does: crawlability, indexing, metadata, links and speed. An AI SEO audit also asks whether AI crawlers are allowed in, whether your words exist without JavaScript, and whether a machine can tell what you sell. RankX AI keeps the two apart: the website audit scores technical condition, AI Readiness scores whether assistants can reach and read you, and the two numbers are never blended, because a blend would let a healthy site hide an invisible one. AI Readiness also notes whether an llms.txt file exists, though no assistant has been shown to cite a site more for having one.

Mostly not. The crawlers that feed ChatGPT, Claude and Perplexity fetch your HTML and do not run JavaScript (Vercel, December 2024); Googlebot and Applebot do render. So words that only appear after scripts run may not exist for most AI assistants. RankX AI’s AI Readiness flags pages whose main content needs JavaScript. The website audit crawl renders JavaScript on every plan except Starter, which is how Google reads a page; AI Readiness is the check that reads it the way the AI crawlers do.

RankX AI’s AI Readiness reads your robots.txt for each named AI crawler, including OAI-SearchBot, GPTBot, Claude-SearchBot, ClaudeBot, PerplexityBot and Google-Extended, and names the rule that matched. A blocked search crawler is reported as an issue, because it removes you from that assistant’s answers; a training-only block is a warning to confirm, because opting out of training does not. The website audit separately flags a site with no robots.txt at all. robots.txt is not the only gate: a CDN or firewall can turn an AI crawler away before it reads the file, so check your host’s bot settings too.

As many as you choose, up to 2,000 pages a crawl: no plan caps crawl size. Before the crawl starts, RankX AI ranks your pages so service, product, location and landing pages go first and tag archives, pagination and policy pages go last. The first 20 are certain to be crawled, and the rest are found by following links from your site. A single page, or a list of up to 50 pages you name, can be checked on its own.

Site audits are unlimited on every plan, so there is no monthly audit count to run out of; the credit wallet meters the crawl. A full crawl costs 1 credit a page, capped at 50 credits up to 100 pages, 100 up to 250, 175 up to 500, and 250 for anything larger, plus 3 credits for the homepage performance check. A list of pages you name costs 2 credits a page with a 10-page minimum, and the scheduled homepage re-check costs 1 credit. Plans and rates are on the pricing page.

No. Running an audit is read-only. The crawl requests pages the way a search engine crawler does and reads what comes back: the HTML, the links, the response codes and the timings. The crawl never logs in, never submits a form and never writes anything to your site. Applying a fix is a separate step you confirm yourself, described below.

Re-run a full crawl after you ship meaningful changes, because the comparison is where the value is: RankX AI diffs each audit against the previous one and tags every finding as new, fixed or ongoing. Between full crawls, scheduled audits re-check your homepage on the cadence you choose, weekly by default, so drift on your busiest page is caught early.

Yes. The free AI search readiness audit needs no account: give it a domain and RankX AI samples up to 6 key pages and scores 23 AI readiness checks, from crawler access to pricing pages, reporting any check it could not run as not assessed. It is a sample, not a crawl. The full website audit, with 48 technical and content checks across up to 2,000 pages, page history and a fix plan, comes with the 7-day trial.

RankX AI writes a fix plan from the findings, with steps for the platform your site runs on and an effort grade on each fix, and one click files it as tracked tasks, deduplicated against work already open. An AI assistant can draft any single task from its finding. For title and meta description fixes on a connected WordPress site, RankX AI can apply the change itself: you see the exact before and after, confirm it, and keep an undo that restores the previous values exactly. Where it cannot write, the task carries a complete brief for a developer or a coding agent.

When organic traffic falls, a website audit can rule the on-site causes in or out. RankX AI’s audit finds broken internal links, redirect chains, canonicals pointing at broken pages, noindex tags and sitemap URLs that no longer resolve, and the comparison with the previous audit tags each finding new, fixed or ongoing, so a problem that arrived with a release stands out. Core updates, a competitor’s gains and lost links sit off your site, and the guide to why Google rankings drop walks through those.

No. RankX AI runs the crawl from one button, explains every finding in plain language with why it matters, ranks the list so the costliest problem is first, and writes fix steps for the platform your site runs on. Technical issues still need someone to fix them, which is why each finding becomes a task you can assign to a teammate or hand to a developer.

Not by itself: an audit finds problems, and fixing them is what can help. Removing a crawl block, a broken canonical or a noindex on a page that should rank takes away a reason to be skipped, but no tool can promise a position, and Google states that third-party tools have no access to its ranking data. RankX AI’s health score is its own measurement, not a Google metric. Measure the outcome with the Google rank tracker and AI Visibility.

Yes. Any tab of the report prints from your browser, with a header naming the website, the tab and the health score, so the SEO report can go to a client as it stands. Each website keeps its own audit history, so the next report shows what changed since the last one.
