Number of DoFollow External Links

Number of DoFollow External Links counts the links on a page that point to other websites and are not marked nofollow. It returns a whole number, and a higher count is not inherently better — read it as an observation about how a page cites the wider web, not a target to hit.

What it measures

This factor counts absolute links to other hosts whose rel value does not contain nofollow. “DoFollow” here means the absence of that directive — it is not an HTML attribute you add. A link is external when its destination host differs from the host of the page being analyzed, and it is a “dofollow” external link when nothing in its rel tells crawlers to skip it.

How RankGear measures it

RankGear parses the anchor tags in the rendered page body, requires an http: or https: destination, and compares the destination host with the analyzed page’s host. Links to a different host are external. Among those, it counts the ones whose trimmed, lowercased rel value lacks nofollow. Relative URLs and non-http(s) destinations are excluded before counting.

What RankGear looks for

<!-- counted: external host, rel has no nofollow -->
<a href="https://example.org/study">source</a>

<!-- not counted: nofollow present in rel -->
<a href="https://example.org/study" rel="nofollow">source</a>

<!-- not counted: relative / same-host URL -->
<a href="/pricing">pricing</a>
Link on the pageCounted?
External host, rel lacks nofollowYes
External host, rel contains nofollowNo
Relative or same-host URLNo (not classified as external)
Non-http(s) destination (mailto:, tel:, javascript:)No
External host with rel="sponsored" or rel="ugc" (no nofollow)Yes — those directives are separate from nofollow

How to optimize it

Link to authoritative external resources when they support a claim, provide evidence, identify a source, or help users complete a task. Use descriptive anchor text, and confirm destinations stay trustworthy and relevant over time. Treat the count as an observation rather than a target — do not add or strip links just to move the number.

Important considerations

  • More external links are not inherently better — relevance and support for the claim matter more than volume.
  • Relative URLs are not classified as external, so they never enter this count.
  • The sponsored and ugc directives are treated separately from nofollow in this calculation; only nofollow excludes a link here.
  • Avoid adding or removing links solely to reach a numeric target.
  • This is a prioritization signal that tracks with position within a measured result set — it is a correlation, not a guarantee that any given count will change a page’s ranking.
