Dofollow link
A dofollow link is a standard link that passes ranking signals (link equity) to the page it points to.
By default, every link is dofollow. There is no actual rel="dofollow" attribute; a link is simply dofollow when it carries no rel="nofollow", rel="sponsored", or rel="ugc" value. These are the links that pass link equity and influence rankings, which makes them the main prize in most link-building campaigns.
Because dofollow links transfer authority, their context matters enormously. A dofollow contextual link from a relevant, high-domain rating page is what moves the needle, while a dofollow link from a spammy or irrelevant source can do more harm than good. The attribute alone does not guarantee value.
An important caveat: a link profile made up almost entirely of dofollow links with commercial exact match anchor text looks unnatural to Google and is a classic over optimization pattern. Real profiles naturally include a healthy mix of dofollow, nofollow link, and branded links, so do not engineer for 100 percent dofollow.
