Free online SEO analysis, professional grade
Not the usual single-page scan: the tool discovers the site's pages from the sitemap, analyses a sample of them and also checks the server, security and AI readiness. At the end: a score, a prioritised action plan and a printable report. No email required.
What the tool checks
🖥️ Server
HTTPS and redirects, www/non-www duplicates, HSTS, compression, security headers, response speed.
⚙️ Technical
Indexability, canonical tags, mobile viewport, robots.txt, sitemap and URL count, mixed content, hreflang.
📝 Content
Title and description (with lengths), H1/H2, amount of text, image alt text and formats, lazy loading, internal links.
🤖 AI readiness
Schema.org structured data, Open Graph, FAQ markup, AI crawler access (GPTBot, ClaudeBot, PerplexityBot), llms.txt.
The tool analyses up to 5 pages per site (home page + a sample from the sitemap), plus the domain's service files. Use is permitted only on sites you own or are authorised to test; anti-abuse protections are in place. See the terms and privacy policy.
How to read your site's SEO analysis
The score is a compass, not a grade
A serious SEO analysis doesn't stop at the home page: this SEO check downloads the sitemap, picks a sample of pages and compares them with each other — that's where the real problems surface, such as duplicate titles or sections with no text. The score out of 100 tells you where to start; the action plan tells you in what order.
The four dimensions that matter
Server and security (HTTPS, redirects, headers), technical SEO (indexability, canonical tags, sitemap), content (title, description, structure, images) and AI readiness: how readable the site is for ChatGPT, Perplexity and Google's AI Overviews, which today answer before the classic results do.
Free analysis today, strategy tomorrow
Use the report as your starting snapshot: fix the first three problems, run the analysis again in a month and compare the scores. When the technical problems are solved and the site still isn't climbing, that's the time for proper consulting: the right keywords, content, authority.
Built by someone who does SEO for a living
This tool isn't a subscription service dressed up as a freebie: I built it myself, Alessandro Mari, with the same checks I run in my paid audits. If the report proves useful, you know where to find me.
Frequently asked questions about SEO analysis
What is an SEO analysis of a website?
It's the technical and content check that measures how readable and competitive a site is for Google: indexing, speed, titles and descriptions, text structure, structured data. This tool runs it online across several pages of the site, for free.
Is the tool really free? Do I need to register?
Yes, it's free and asks for no email or registration. It's the calling card for my work: if the report is useful to you, you know who built the tool.
How many pages does the SEO check analyse?
Up to 5 pages per site: the home page plus a sample picked automatically from the sitemap to cover different sections, as well as the domain's service files (robots.txt, sitemap, certificate, security headers).
What does the score out of 100 mean?
It's a summary of four categories: server and security, technical SEO, content and AI readiness. Above 80 the site is in good shape; between 60 and 80 there's real room for improvement; below 60 it's best to start with the action plan, which the tool ranks by impact.
What's the difference between this automated analysis and a professional audit?
The tool sees what a machine can see, and it sees it in 30 seconds. A human audit finds the causes, the right order of priorities and the opportunities your competitors are missing: it starts from €249, or free in a lighter version.
Does the tool also check AI readiness (ChatGPT, AI Overviews)?
Yes: it verifies Schema.org structured data, Open Graph, FAQ markup, AI crawler access (GPTBot, ClaudeBot, PerplexityBot) and whether an llms.txt file is present. Around half of Google searches now show an AI answer before the results: being in there is the new first position.
How often should I rerun the analysis?
After every major change to the site and in any case once a month: Google changes, and so do your competitors. The report can be printed or saved as a PDF to compare scores over time.
