Try it now: Paste any URL into our free SEO checker — 30+ checks, dual Google + AI score, no login required.
What does a free SEO checker do?
A free SEO checker analyzes a web page against the technical and content requirements that search engines use to rank pages. You paste a URL, the tool fetches the live page, and within seconds you get a breakdown of what's working and what needs fixing.
The best free SEO checkers go beyond surface metrics (title tag length, meta description) to check the signals that actually move rankings: structured data quality, content depth, internal linking, performance indicators, and — in 2025 — AI search readiness.
Most free SEO checkers require you to create an account. Ours doesn't. Paste a URL, get a full report instantly.
What our free SEO checker analyzes
Our analyzer runs 30+ checks across five categories simultaneously. Here's what each category covers and why it matters.
Technical SEO
The foundational signals Google uses to crawl and index your page.
- ✓Title tag presence, length (50–60 chars), and keyword inclusion
- ✓Meta description presence and length (150–160 chars)
- ✓Canonical URL declared to prevent duplicate content
- ✓HTTPS (required — Google penalizes HTTP pages)
- ✓Meta robots directives (noindex, nofollow detection)
Content Quality
Signals that tell Google whether your page has enough substance to rank.
- ✓Word count (300+ words minimum for rankability)
- ✓H1–H6 heading hierarchy (one H1, proper nesting)
- ✓Image alt text coverage (required for image search and accessibility)
- ✓Internal linking (distributes PageRank, helps crawlability)
- ✓External linking to authoritative sources
Performance
Page speed signals that affect Core Web Vitals and rankings.
- ✓Render-blocking scripts in <head> (delay First Contentful Paint)
- ✓Image lazy loading (reduces initial page weight)
- ✓HTML payload size (large pages slow down crawling)
- ✓Preconnect hints for external resources (reduces DNS latency)
Social & Open Graph
How your page appears in social shares and link previews.
- ✓og:title, og:description, og:image presence
- ✓Twitter Card meta tags
- ✓Open Graph type declaration
AI Search Readiness
Unique to our tool: checks that determine whether AI assistants will cite your page. No other free SEO checker includes these.
- ✓llms.txt file presence and validity
- ✓GPTBot, ClaudeBot, PerplexityBot access in robots.txt
- ✓Article schema with author name and publication dates
- ✓Content readable without JavaScript rendering
- ✓Summary or TL;DR in first 150 words
- ✓Outbound citations to primary sources
- ✓RSS / Atom feed discoverability
How to use the SEO checker
Paste any public URL
Enter the full URL of the page you want to audit, including the protocol (https://). You can analyze your homepage, a blog post, a product page — any publicly accessible URL.
Wait a few seconds
We fetch the live page, its robots.txt, and llms.txt simultaneously. Analysis takes 3–8 seconds depending on your server response time.
Read your dual-score report
Your report shows a Google score (0–100) and an AI score (0–100) as side-by-side rings. Below the scores, every check is grouped by category with a pass/fail status and a specific explanation.
Get Claude-written fixes
Each failed check includes an AI-generated recommendation with the exact markup, copy, or configuration change you need to paste in. Tagged by lens: Google, AI, or both.
Share the report link
Every report gets a unique URL that stays live for 24 hours. Copy it to share with your team, developer, or client.
How is this different from other free SEO checkers?
Most free SEO checkers — including the free tiers of Semrush, Ahrefs, and Moz — were built before AI search existed. They check for Google's traditional ranking signals only. That made sense in 2020. In 2025, it leaves a major blind spot.
AI assistants (ChatGPT, Perplexity, Claude, Gemini) are answering a growing share of search queries directly, with citations. Appearing in those citations requires passing checks that traditional tools don't run: llms.txt, AI crawler permissions, author attribution in JSON-LD, JS-free content rendering.
Our tool is the only free SEO checker that scores both tracks — traditional Google SEO and AI search readiness — side by side. You see a single score for each, the category breakdown, and fix-ready recommendations for both.
Frequently asked questions
Is this SEO checker really free?
Yes. No account, no credit card, no rate limit on URLs. Analyze as many pages as you like. We're free because we want our AI SEO checks to be accessible to every site, not just teams with $99/month budgets.
How accurate is the score?
The score reflects the specific technical and content checks we run — not a prediction of your Google ranking. SEO is multifactorial: backlinks, domain authority, and content freshness all play a role that no on-page tool can capture. Our score is a reliable measure of on-page and on-site SEO health.
Can I check multiple pages?
Yes. Each analysis runs independently — you can check your homepage, your most important blog posts, and your key product pages one by one. There's no limit on the number of URLs you can analyze.
Does this tool crawl my whole site?
No. We analyze a single URL at a time. We fetch the page you enter, plus its robots.txt and llms.txt. We don't crawl your full site, so we don't check site-wide issues like broken links or redirect chains across pages.
Is my URL stored or shared?
Your report is stored temporarily (24 hours) to enable sharing via the report link. We don't sell or share URL data. The only reason we store reports is to give you a shareable link.
