Free SEO Audit Tool — paste a URL, get a brutally honest audit in 30 seconds.

Yes — 100% free, no signup, no email, no credit card. There's a per-IP fair-use cap (a small number of audits per day) so the underlying GPT API stays affordable for everyone. Each audit costs us real money in OpenAI tokens, so we throttle abuse but never paywall a legitimate site owner.

FeedPulse runs the audit on GPT-5.2 via OpenAI. That's the same frontier reasoning model used by ChatGPT Pro and Microsoft Copilot. We pick GPT-5.2 specifically (not a smaller or distilled model) because SEO advice quality is the entire product — running a cheaper model would mean cheaper, worse audits.

The audit pulls your page's live HTML and analyses: title tag (length, primary keyword, click appeal), meta description (presence, length, CTR signals), H1 / H2 / H3 hierarchy, body content quality (readability, depth, on-topic relevance), keyword targeting (primary keyword + missing long-tail opportunities), and overall E-E-A-T signals. You get a numeric score plus 5 prioritised, actionable fixes you can implement that day.

Surfer / Frase / SEO.ai start at $49–$99 per month and need an account. They optimise content against ranking competitors using SERP scraping. This tool is free, anonymous, single-page, and instant — designed for the 95% of site owners who just want to know 'is my page well-optimised right now?' without subscribing to anything. Different use case, zero cost.

The audit fetches your page exactly the way Googlebot does — anonymous, no cookies, no login. So it works on any publicly-crawlable URL: blog posts, product pages, landing pages, even single-page apps with server-side rendering. Paywalled / member-only / logged-in-only pages can't be audited because the AI can only score what Google can also see.
