Frequently Asked Questions
Is SEOSonar really free to use?
Yes. You can analyze any public website for free, with no account or credit card required. We display advertising to keep the tool free for everyone.
How is the SEO score calculated?
We run 15+ weighted checks covering content, technical SEO, performance and accessibility. Each check contributes to your overall score out of 100 based on how important it is for search rankings.
Can I check any website, not just my own?
Yes — you can analyze your own site or any competitor's public page to see how it's optimized and find opportunities to outrank it.
Does a high score guarantee a #1 Google ranking?
No tool can guarantee rankings — Google uses hundreds of signals, including backlinks and user behavior that aren't visible on the page. SEOSonar focuses on the on-page and technical factors you can control directly.
Why can't SEOSonar scan some websites?
Some sites block automated requests, require logins, or aren't reachable publicly. If a scan fails, double check the URL and try again.
