Data FAQ

Answers to common questions about Rankfield's Site Strength, referring domains and web graph data.

#Why is a domain missing?

It is not in the current web graph release, so the API answers 200 with "inGraph": false and zeros. That does not mean the domain is offline or has no links: our crawl data may not include a page that links to it.

#Why is referringDomains null?

The domain is in the graph, but its count was unavailable for the lookup. null keeps "unknown" apart from a measured zero.

#Why is topReferrers empty?

There is no detail for this domain in the index. It does not prove that no site links to it.

#Does a higher Site Strength mean more traffic?

No. It describes link evidence in the graph. It does not estimate visits, rankings or conversions.

#Can I compare Site Strength with Moz or Ahrefs?

Not directly. Those scores use their own indexes, scales and methods. Compare Rankfield scores with each other.

#Does the web graph see every link?

No. It records the links on the pages that the crawls behind it fetched, so counts and lists can be lower than a full backlink index.

#How often does the data change?

When a new web graph release is built from newer crawls and loaded. Check Get Dataset Status for the release in use.
