Do entity-based query suggestions impact anchor text diversity?

Yeah, using entity-based suggestions as anchor text will usually help your anchor diversity, not hurt it, since you're avoiding the same exact match phrases over and over. Google likes seeing a spread of related terms and natural language, so pulling suggestions tied to entities from things like Google Autosuggest, People Also Ask, or Knowledge Panels mixes up your anchors. Just make sure you don't swing too hard into overusing any single entity phrase either. I checked a few client backlink profiles in Ahrefs and SEMrush recently and anchors based on suggestion phrases are spreading risk pretty well, no weird penalties or tanked rankings that I could trace back to diversified entity anchors. Keep mixing in branded/naked URLs and a range of generic anchors too.
