Over-use hashtags -
Using too many hashtags on Twitter is overkill and
makes you look desperate. You can only use 140
characters on Twitter per tweet to say what you
intend to say. It wouldn’t be smart to have your tweet
mostly made up of hashtags.Hashtags are good in
moderation but if you take it too far, people won’t be
following you for very long.
Side note: Hashtags are not #meant #to #be #used #like #this. This is very unflattering and
likely to drive followers away from your profile. Hashtags are meant to be used #likethis.
