Your link tags are hints now, not commands

As of the first of this month, the nofollow link attribute became a hint rather than a directive for crawling and indexing — a small-sounding change with a real shift behind it. To feel the difference, recall how nofollow worked before. When you marked a link rel="nofollow", Google treated the tag as a command: it would not follow the link, would not count it, would behave as though the link simply did not exist. The control was yours and it was absolute — nofollow meant ignore, and Google ignored. From this month, that absoluteness is gone. Google now treats nofollow as a hint, which means it looks at the link and decides for itself how to use it, rather than obeying the tag automatically. This completes a transition Google set out last September, when it introduced two companion attributes — sponsored and ugc — and announced that all three would function as hints about which links to consider or exclude. Those two were already being used as hints for ranking from the time of the announcement; what happened this month is that nofollow joined them as a hint for crawling and indexing too. The throughline of the whole change is a transfer of who decides. The old nofollow let you issue an instruction the engine carried out; the new model lets you offer a description the engine takes into account. Your link markup went from a command Google follows to a signal Google weighs — and that reframing, from instruction to description, is the real substance of the update.

Underneath the change sit three values of the rel attribute, each there to describe a different kind of outbound link. rel="sponsored" marks a link created as part of advertising, a sponsorship, an affiliate arrangement, or any other compensation — it says, plainly, this link is paid. rel="ugc" marks a link inside user-generated content such as a blog comment or a forum post — it says this link was placed by a user, not by you. And rel="nofollow", the original of the three, covers the general case where you want to link to a page without implying any endorsement of it or passing along ranking credit — it says I am pointing to this without vouching for it. Because these describe different facets of a single link rather than competing labels, they can be combined: rel="ugc sponsored" is a perfectly valid way to mark a sponsored link that appears within user-generated content, and you can pair the new attributes with nofollow as well for backwards compatibility. The thread that ties them together is worth saying directly, because it is the heart of the matter: the rel attribute exists to describe a relationship — rel is literally short for relationship — and these values let you state, in markup, what kind of link each outbound connection is. One says paid, one says from a user, one says not endorsed. They are not levers you pull to change rankings; they are labels you apply to tell the truth about your links, so the engine reading your page understands the nature of what it is pointing at.

The reason Google gave for the shift is the most illuminating part of the whole announcement, because it explains what a directive was costing. Under the old model, a nofollow link was invisible to Google’s systems — the moment you tagged it, the link and everything about it dropped out of consideration. But links carry information whether or not you endorse them. The words inside a link describe the page it points at; the overall web of links, including the unnatural and the untrusted ones, helps Google understand how the web is structured and where manipulation is happening. When nofollow meant ignore entirely, all of that was thrown away every time someone tagged a link — a real loss of understanding in exchange for a binary on-off switch. The hint model recovers it. Google can now look at a nofollow, sponsored, or ugc link, read its anchor text, factor it into its model of linking patterns, and use it however its systems judge appropriate, while still respecting the thing you were actually trying to signal: that this particular link should not be treated as your first-party endorsement, your personal vouching for the destination. So your ability to say not endorsed survives intact; what changes is that Google no longer responds by pretending the link is not there. The cleanest way to hold the distinction is this: a directive orders an outcome, a hint informs a judgement. You used to command; now you describe, and Google decides what the description is worth. Reading that kind of distinction precisely is the markup discipline the AC Group has worked by for {years} years.

The right response is to classify your outbound links accurately and to resist reading the change as a ranking opportunity. Start with the reassurance: you do not need to touch any nofollow links you already have. Existing nofollow markup keeps doing its job — flagging links you do not endorse and keeping paid links compliant with Google’s guidelines — and there is no penalty for leaving it exactly as it is. Going forward, reach for the most specific attribute that fits the link. Use rel="sponsored" for paid, affiliate, and advertising links, which Google recommends and which keeps you cleanly on the right side of its rules about paid links; use rel="ugc" for the links your users add in comments and forums; and keep plain rel="nofollow" for the remaining cases where you just do not want to endorse a destination. Where a link belongs to more than one category, combine the attributes. The one thing to avoid is treating any of this as a ranking play: Google’s search liaison was explicit that the change brings no ranking boost, so manipulating attributes in hope of one is wasted effort that can muddy the honest picture of your links. Hold the right frame instead — this is markup hygiene. You are describing your links truthfully so Google understands your site and the sites you connect to, which serves the web and makes your own linking legible. Building accurate, honest link markup as part of a clearly described site is the kind of entity and schema work the AC Group has done for {years} years.
