What affects Instagram reach? Likes, comments, save – we repeat, as if wound up. However tape ranking algorithm takes into account thousands of factors. This, for example, is still:
✅ post reading / viewing time ✅ number of comments from one person (discussion) ✅ send a post to friends or not (“airplane”) ✅ speed set of likes in the first hour after publications ✅ how close are the links with the blogger (general subscriptions and subscribers, friends in other social services. networks) ✅ communication with a person in direct ✅ communication with a person on his page ✅ territorial affinity ✅ blog topics
And a bunch, a bunch of other factors, not just likes, comments and conservation. But if you take purely these three factors, then the most important of which are comments.
