Best free technical SEO audit tool
HubSEO checks any public website free, with no signup. It opens your page in a real browser and measures how fast it loads, whether Google can index it, whether AI assistants like ChatGPT are blocked, and where visitors get stuck. Every finding is explained in plain English with the fix to make first.
What the free check looks at
Every check opens your page in a real browser, the same way a visitor would, and measures what actually happens. No guesswork, no invented scores.
You see the whole report straight away. No signup form, no email required, and nothing is hidden until you pay.
| What we check | What we measure | What you get |
|---|---|---|
| How fast your pages open | Load time, stability, time to first byte | Plain-English causes and the fix, with the numbers |
| Whether Google can find you | Indexability, page titles, headings, links | The specific pages and settings to change |
| Whether AI can describe you | GPTBot, ClaudeBot and PerplexityBot access | Whether each assistant is blocked, and how to unblock it |
| Ease of use for visitors | Alt text, colour contrast, labels, headings | Where people get stuck and what to correct |
What to do with your report
The report puts the biggest problem first. Work through it in this order:
- 1Start with the top-ranked issue. It is the one costing you the most visitors.
- 2Send the ready-made fix note to your web person, or paste it into an AI coding tool.
- 3Re-run the check on the same page to confirm the change actually worked.
- 4Check again later to catch anything new that has appeared.
Frequently Asked Questions
Is this really free, with no signup?
Yes. Enter any public web address and read the full report with no email, password, or card. You get one check every 30 days without an account. A free account raises that to three checks a month.
How long does a check take?
Usually 15 to 30 seconds. We open your page in a real browser and measure it live, so slower sites take longer.
Can I check a staging or password-protected site?
No. Checks only work on publicly reachable pages. Anything behind a login or IP restriction cannot be measured.
What happens after the free check?
Nothing is charged and nothing is created on your site. If you want ongoing checks, saved history, or a one-time lifetime option, the pricing page shows what is on sale right now.
