Are nofollow links starting to matter as much as dofollow for AI search?

Discover how AI search engines interpret dofollow and nofollow links, and why a balanced backlink profile is now critical for visibility.

Is the dofollow vs nofollow debate outdated in the era of AI search?

I’ve been spending a lot of time recently digging into backlink patterns, but with a slightly different lens than usual — not just rankings, but how sites are getting picked up and cited inside AI-generated answers (Google AI Overviews, Perplexity, ChatGPT-style responses, etc.).

And honestly, something keeps coming up that doesn’t fully align with the traditional SEO mindset.

For years, the rule has been pretty clear:
dofollow links = authority and rankings
nofollow links = nice to have, but mostly ignored

That model made sense when everything revolved around PageRank flow. But when you start looking at how AI systems surface sources, the picture feels a bit different.

What I’ve been noticing (across a mix of projects and datasets):

First, pages that consistently show up in AI answers rarely have “perfect” dofollow-heavy link profiles. Instead, they tend to have a very mixed footprint — blog mentions, forum discussions, citations, directories, even social and community links that are technically nofollow.

Second, nofollow links seem to still play a role in context building. Even if they don’t pass traditional authority, they help reinforce things like:

  • brand/entity association
  • topical relevance
  • co-occurrence with certain keywords or themes

And that becomes important when AI models try to decide “who is worth citing” rather than just “who ranks #1.”

Third, overly clean backlink profiles (for example, mostly high-DA dofollow guest posts) sometimes look less aligned with what AI systems pick up. It’s almost like they lack the broader web footprint that signals real-world presence.

What this suggests — at least from what I’ve seen — is that links are being interpreted more holistically now.

Not just:
“Does this link pass authority?”

But more like:
“Is this site being talked about across the web in a natural, consistent way?”

That includes:

  • forum mentions
  • Reddit discussions
  • niche community links
  • citations in articles without optimised anchor text
  • And yes, a good portion of those are nofollow

Another interesting pattern is that anchor text seems to matter less in isolation compared to the overall context. A branded mention in a discussion thread can sometimes align more with AI citations than a perfectly optimised keyword anchor in a guest post.

To be clear, I’m not saying dofollow links are losing value. They still matter — especially for traditional rankings. But the gap between dofollow and nofollow, at least in terms of visibility in AI-driven answers, seems much smaller than it used to be.

It also changes how I think about “link building” as a whole.

Instead of chasing only high-authority placements, the focus shifts more toward:

  • being mentioned in relevant conversations
  • appearing across different types of platforms
  • building a footprint that looks natural, not engineered

In a way, it starts to feel less like link building and more like “web presence building.”

Over the past few months, I’ve been testing some of these patterns across different campaigns, including work we’ve been doing at Megrisoft. One thing that stands out is that sites with a broader mix of mentions, not just high-authority dofollow links, tend to get picked up more consistently in AI-driven results

I’m still testing this, so I wouldn’t call it a final conclusion. But the pattern is consistent enough that it’s hard to ignore.

Curious what others are seeing:

  • Have you noticed any change in how link types affect AI visibility?
  • Are nofollow-heavy mentions showing any impact in your projects?
  • Or are you still seeing a strong correlation mainly with dofollow authority?

Would be interesting to compare notes, especially from people running campaigns across different niches.
