Frequently asked questions
Quick answers about our web & SEO tools.
Do you store the websites I check?
No. Live checks are made from our server and the result is sent back to you; nothing is kept.
Why does a check say private address blocked?
For safety our server will not connect to private, internal or cloud metadata addresses.
Will these tools improve my Google ranking?
They show problems and generate correct tags. Rankings also depend on your content and links.
Can I check a site that is not mine?
Yes, public checks like DNS, SSL and headers work on any public website.
