The comment section is the one place volume works against you
On likes, views and saves, more is broadly better up to the point where the numbers stop matching each other. Comments invert that. Each one is legible, and each one is an opportunity to make the post look worse.
Consider what a visitor actually does. They read the top comment. If it says something specific about the post, the post gains credibility. If it says "🔥🔥🔥" and the next four say variations of the same thing, the post gains nothing, and the section reads as filler faster than any like count could.
This is why we sell comments in small quantities and why the smallest packages are the ones we recommend most often. Eight comments that each say something different are a better outcome than eighty that repeat one script.
