How many hashtags to use on LinkedIn
Three to five. That’s plenty for LinkedIn to understand what your post is about, and few enough that the post still looks like it was written by a person.
Mix them. One or two broad tags like #Leadership put you in a big pool. Two or three niche tags like #B2BSales or #ProductManagement put you in front of people who really care.
Tip: Put hashtags at the end, on their own line. Hashtags in the middle of a sentence make it hard to read.
