How do nofollow links perform in AI search visibility (according to Semrush's research)?

Semrush's research indicates that nofollow links contribute significantly to AI search visibility, performing almost as powerfully as dofollow links. This suggests that AI algorithms evaluate the overall link profile and the context of links, rather than strictly adhering to the nofollow attribute for ranking signals. Therefore, even though nofollow links traditionally didn't pass "link juice" in the same way as dofollow links, their presence still signals relevance and authority to AI search engines. The other options are incorrect because nofollow links are not limited to local businesses, are not necessarily less valuable than in traditional SEO (especially with AI's evolving understanding of links), and certainly have some impact rather than none at all.
