Frequently asked questions

How is the score calculated?

Each check has a weighted category score. Categories are combined into an overall 0–100 health score, renormalised so unmeasured categories don’t unfairly penalise you.

Does the crawler respect robots.txt?

Yes. SEO Harbor follows robots.txt directives and respects crawl budget, mirroring how search engines crawl your site.

Is my crawl data real?

Absolutely. All metrics β€” titles, headings, links, images, schema, performance β€” come from a live crawl of your pages, never fabricated.

How fast will I get results?

Audits typically complete in under a minute for small sites, and a few minutes for large ones.
