Frequently Asked Questions

How does the crawler work?
Our crawler simulates a Googlebot visit. It parses your HTML, checks server headers, and pings Google's PSI API for performance data.
Is the PDF report really free?
Yes! You can generate unlimited PDF reports. If you want to save project history, you'll need to create a free account.
