Website SEO & On-Page Auditor FAQ

What is an on-page SEO audit?

An on-page SEO audit evaluates elements directly on your webpage such as titles, meta tags, headers, and schema to ensure search engines can properly index and rank your content.

Why is the H1 heading check important?

Search engines use the H1 tag to understand the main topic of your page. Having exactly one descriptive H1 heading provides clear structural context for both crawlers and visitors.

How does the overall SEO score get calculated?

Scores start at 100 and deduct points for critical issues like noindex directives, missing titles, missing meta descriptions, and unoptimized image alt tags.

Can I audit private or staging websites?

Yes, you can paste the raw HTML source code directly into the auditor tab without exposing staging servers or needing external network access.
