A dofollow link carries no blocking rel value, so search engines can pass PageRank (link equity) from the linking page to the target — this is the default for ordinary links and what makes backlinks valuable for rankings. A nofollow link adds rel="nofollow", which tells search engines not to pass ranking signals through it; Google introduced this in 2005 for untrusted or paid links. Since 2020 Google treats nofollow as a hint rather than a strict directive, but it still signals that the link should not pass equity. The practical impact is that a dofollow link can boost the target's authority while a nofollow one generally won't. Paste a page's HTML into this checker to see exactly which links are followed and which are walled off, with the rel value for each.

All three sit in a link's rel attribute and signal that it should not pass full ranking equity, but each describes a different reason. Plain rel="nofollow" is the original 2005 catch-all for links you don't vouch for. rel="ugc", added by Google in 2019, marks User-Generated Content such as blog comments and forum posts, where you can't control what readers link to. rel="sponsored", introduced the same year, flags paid, advertising, or affiliate links that Google requires you to disclose. You can combine them, like rel="sponsored nofollow". Using the precise tag gives Google clearer context than a blanket nofollow. This checker reads each link's exact rel value and labels it dofollow, nofollow, UGC, or sponsored, so you can confirm the correct attribute is in place before publishing.

Google's guidelines require that any link you receive payment for — sponsored posts, paid placements, and affiliate links — be marked with rel="sponsored" or at least rel="nofollow". Leaving paid links as plain dofollow can be seen as buying or selling link equity, which violates Google's spam policies and risks an "unnatural links" manual action that can tank a site's rankings. Tagging the link tells search engines not to pass PageRank through a relationship you were compensated for, keeping you compliant while still giving readers the link. The same applies to large-scale affiliate programs. This checker scans a page's HTML and surfaces every link's rel value, so you can quickly verify your sponsored and affiliate links actually carry the right attribute instead of silently passing equity.

Pressing Ctrl+U (or Cmd+Option+U on a Mac) shows a page's raw HTML, but it won't include links that JavaScript injects after the page loads, so those would be missed if you paste the view-source output. To capture dynamic links, open your browser's DevTools, find the top-level html element in the Elements panel, right-click it, choose Copy then Copy outerHTML, and paste that rendered markup into the tool instead. Because DevTools shows the live DOM after scripts have run, the copied HTML contains the JavaScript-added anchors along with the static ones. This matters for sites built on frameworks where most content renders client-side. Paste either the raw source or the rendered DOM into this checker and it parses every a tag it finds, classifying each by its rel attribute.

Nofollow links don't pass PageRank the way dofollow links do, so they won't directly boost your rankings through link equity. That doesn't make them worthless, though. They still drive referral traffic when real people click them, build brand visibility and awareness, and can diversify a backlink profile so it looks more natural than one made up only of followed links. Since 2020 Google also treats nofollow as a hint, meaning it may, in some cases, still consider the link for discovery or context. So a mix of nofollow and dofollow links is normal and healthy, while an unusually high share of either can be worth reviewing. Paste a page's HTML into this checker to see the full breakdown of nofollow versus dofollow links and judge the balance for yourself.
