How our tools work

Paste any public URL

Your site, a competitor, a client. Anything with a public HTTP address.

We inspect the HTML

Our scraper fetches the page, reads the markup, and checks the response headers.

Get a clean report in seconds

Structured results, colour-coded status, plain-English explanations. Copy the URL to share with your team.

Tool questions

Can I use these on staging or private sites?+

No. Our scraper needs public HTTP access. Internal or password-protected pages will fail.

How often can I check a URL?+

Unlimited. There is no rate limit on the free tools.

Are these the same checks as the full audit?+

They are a subset. The full audit runs 30+ signals across 7 categories and gives you a single Visibility Score. These tools focus on one area each.

Can I automate these tools via API?+

API access is available on the Agency plan. Contact us for details.

These tools are just the start
