Two ways to audit your website
One page, free. Our free site check runs Google's Lighthouse on any public page and gives you the SEO, Performance, Accessibility and Best Practices scores, Core Web Vitals, and plain English fixes. It is the quickest way to see where a page stands.
The whole site. One page rarely tells the full story. Duplicate titles, missing descriptions and broken pages usually show up across a site, not on the homepage. Our SEO Audit Tool reads your sitemap, or follows your links, and audits every page it finds.

How to run a full site SEO audit
- Open the SEO Audit Tool on Apify. A free Apify account is enough.
- Enter your homepage. The tool finds your sitemap through robots.txt. If there is none, it follows links from the homepage instead.
- Set how many pages to check. 20 is a good first pass. Raise it for a deeper audit.
- Run it and open the HTML report, or download every row as CSV or Excel.
- Fix the top items first, then run it again to see the score move.
What the audit looks at
- The basics Google reads first. Title, meta description, H1, canonical tag, and whether the page can be indexed.
- Mobile and content. Viewport tag, word count, heading structure and image alt text.
- Technical health. Status codes, redirect chains, broken links, hreflang, structured data, sitemap and robots.txt.
- Site wide problems. Duplicate titles and descriptions across pages, and the share of pages each issue affects.
Every issue comes with why it matters and how to fix it, written for a business owner, not just a developer.
A real sample
We audited a few public sites on November 11, 2026, with a small page cap. These are the page scores and the top issue on each page, straight from the output.
| Page | Score | Grade | Top issue |
|---|---|---|---|
| crawlee.dev | 92 | A | Very little text on the page |
| crawlee.dev/blog | 88 | B | No H1 heading |
| docs.apify.com | 86 | B | Missing meta description |
| web.dev | 80 | B | No H1 heading |
| web.dev/html | 77 | C | Missing meta description |
| sitemaps.org | 70 | C | Not set up for mobile (no viewport tag) |
| sitemaps.org/protocol.html | 67 | D | Missing meta description |
Each site also gets a summary row. This is part of the one for crawlee.dev:
{
"rowType": "site-summary",
"site": "https://crawlee.dev",
"siteScore": 90,
"grade": "A",
"pagesAudited": 2,
"brokenPages": 0,
"topFixes": [
{ "rank": 1, "fix": "No H1 heading", "pagesAffected": 1 },
{ "rank": 2, "fix": "Very little text on the page", "pagesAffected": 1 },
{ "rank": 3, "fix": "Title is too long (Google will cut it off)", "pagesAffected": 1 }
]
}How it compares
Several big names offer free site audits. They are good, and one of them may be all you need.
| Tool | Which sites | Free limit | Paid price |
|---|---|---|---|
| Ahrefs Webmaster Tools | Only sites you own and verify | 5,000 crawl credits per project a month | Free with an account |
| Screaming Frog SEO Spider | Any site, desktop app you install | 500 URLs per crawl | £199 a year per user |
| SiteScope | Any site, in the browser | 300 pages per audit | Free, no signup |
| SEO Audit Tool (we built it) | Any public site, runs in the cloud | Apify's free monthly credit covers small tests | $2 per 1,000 audited pages, failures free |
Prices and limits are from each company's public page, checked November 11, 2026. If one has changed, email [email protected] and we will fix it.
Our honest take: if you only care about one site you own, Ahrefs Webmaster Tools is hard to beat for free. Screaming Frog is the standard desktop crawler for deep technical work. Our tool fits when you audit sites you do not own, like prospects or client sites, when you want several sites in one run, or when the audit should run on a schedule and land in a spreadsheet or n8n workflow. You do not need to verify ownership, install anything, or pay a monthly fee.
What it costs
The one page check is free. The full audit is $2 per 1,000 audited pages, so a 100 page site costs $0.20 and a 300 page site costs $0.60. The site summary, the HTML report and any page that fails to load are free. You can set a page cap or a maximum charge before you start.

Questions
Is the website SEO audit really free?
The one page check on our site is free with no account. The full site audit runs on Apify at $2 per 1,000 pages, and new Apify accounts get a small free monthly credit, so a first audit of a small site usually costs you nothing out of pocket. We would rather tell you that up front than hide it.
What does the audit check?
Titles and meta descriptions, H1 and heading structure, canonical tags, noindex and robots rules, mobile viewport, image alt text, structured data, thin content, hreflang, status codes, redirects, broken links, duplicate titles and descriptions, and whether the site has a sitemap and robots.txt.
Does it check backlinks or keyword rankings?
No. It is a technical and on page audit of the pages themselves. It does not estimate backlinks, traffic or rankings, and we would rather not guess at numbers we cannot measure.
Can I send the report to a client?
Yes. Each site gets an HTML report with the score, the top fixes in plain English and the worst pages, which you can open, save or share.
Do you need access to my site?
No. The audit reads public pages the same way a search engine does. Nothing behind a login is checked.
How is this different from Ahrefs or Screaming Frog?
Ahrefs Webmaster Tools is free but only for sites you verify. Screaming Frog is a desktop app, free up to 500 URLs and £199 a year after that. Our tool runs in the cloud on any public site, many sites per run, and you pay per audited page with no subscription.
