What Does This Authority Checker Measure?

This tool combines several separate signals. With an optional Open PageRank API key, it reports Open PageRank on a 0–10 scale. With a required SearchAPI.io key, it runs a Google site: query to estimate indexed pages and show a sample of indexed results. It also checks whether the domain responds over HTTPS.

Open PageRank is a third-party link-authority indicator, not an official Google metric or a universal authority score. Use it as one comparative signal alongside index visibility and HTTPS status; do not treat it as a complete measurement of site quality, topical relevance, or ranking ability.

How to Use This Authority Checker

Enter your SearchAPI.io key, the domain to check, and—if you want the authority score—an Open PageRank API key. Choose the Google country and device used for the index query, then click Check Authority. The result shows Open PageRank when available, an estimated indexed-page count and sample pages, HTTPS status, and the country/device checked.

The country and device controls affect the SearchAPI.io query context. They do not filter or estimate visits. The tool does not return backlink counts or a prospect list. A low indexed-page estimate or failed HTTPS check can justify further investigation, but none of these fields alone proves that a site is high- or low-quality.

Using the Signals Responsibly

Compare Open PageRank only with other Open PageRank results on the same 0–10 scale. Pair the score with a manual review of topical relevance, content quality, ownership, and link placement. The indexed-page estimate comes from a search-result estimate and can fluctuate; use the sample pages to spot-check what Google is surfacing rather than treating the estimate as an exact crawl count.
