In plain English
Information in a link’s HTML that describes its behaviour or relationship, such as nofollow, sponsored or UGC.
Why it matters
This term helps you assess recognition and credibility without reducing SEO to a promise or a single number.
Example
A publisher adds rel=“sponsored” to a compensated product link.
Common misunderstanding
Context matters. This concept does not guarantee rankings and should not be used to justify manipulative link building.
