Free AI & SEO Tools

Check whether AI engines can crawl and cite your site, trace redirect chains that hurt rankings, and audit robots.txt for accidental Googlebot blocks. The three tools every SEO should run quarterly.

Why this matters

Search has split into two ecosystems: traditional Google, and AI engines (ChatGPT, Perplexity, Claude, Gemini, Copilot). The infrastructure that lets each one find and cite your content overlaps but is not identical. A robots.txt rule that's fine for Googlebot can block GPTBot. A 6-hop redirect chain that Google tolerates can confuse AI crawlers entirely.

These three tools cover the basics: see how AI-ready your site is across crawler access / metadata / structure, trace every redirect hop to spot loops or excessive chains, and audit your robots.txt to confirm you're not accidentally blocking the engines you want to be cited by.

Want continuous monitoring instead of one-off?

Each tool above runs a one-off check. To get alerted whenever something changes, set up a continuous monitor:

Continuous version of Redirect Chain Checker. Alerts when a redirect loop, excessive hops, or a broken final destination silently appears after a CMS or framework change.

A single accidental Disallow: / can deindex your entire site. Continuous monitoring catches the change within minutes — long before Googlebot has stopped crawling.

A broken /sitemap.xml stops Google discovering new pages. Continuous monitoring confirms the sitemap stays accessible and valid XML.

Verify critical SEO copy (meta description text, structured data markers, AI-readable content blocks) remains on the page after deploys.

Frequently asked questions

Is the AI SEO Checker the same as Uptrue AI Visibility?
No. The AI SEO Checker is a one-off snapshot — does your site appear AI-ready right now (crawler access, metadata, structure, llms.txt). Uptrue AI Visibility (separate product at aivisibility.uptrue.io) is the continuous tracking layer — does ChatGPT actually cite you for the keywords you target, week after week. The Checker is the doorstep diagnostic; AI Visibility is the rolling vital signs.
How many redirect hops is too many?
Google recommends fewer than 3. Anything over 5 is a strong signal something is wrong (e.g. legacy URL → CDN redirect → HTTPS upgrade → CMS rewrite → final). Long chains slow page load for every visitor and can drop pages from Google's index entirely.
Can I block GPTBot but allow Googlebot?
Yes — robots.txt supports per-user-agent rules. Use `User-agent: GPTBot` followed by `Disallow: /` to block OpenAI, and a separate `User-agent: Googlebot` block to allow Google. The robots.txt Checker shows which user-agents are blocked vs allowed for any site.
My pages aren't in AI search results — is the AI SEO Checker enough?
It diagnoses the technical layer (can crawlers reach you, is structure machine-readable, is llms.txt set up). It does NOT measure whether AI engines cite you for specific queries — for that, use Uptrue AI Visibility. Many sites fix the technical layer and still aren't cited because their content quality / authority isn't there yet. Both are needed.
Are these tools really free?
Yes. All three run against our edge — no signup, no email capture. Use them on any public URL as many times as you want.
