What each network does with hashtags
Instagram refuses more than 30
A caption with more than 30 hashtags is refused, not trimmed.
YouTube ignores them past 15
If a video has more than 15 hashtags, YouTube ignores all of them.
X and LinkedIn set no limit
But on X every hashtag still counts toward the 280 characters.
3 to 5 is plenty
Instagram has said hashtags do not boost reach, so use a few that describe the post.
Questions
Does it suggest hashtags?
No. It tidies and checks the ones you give it. It does not claim any hashtag will reach more people, because that is not something a tool can promise.
