While there's a lot of people telling you what you should do on your Facebook page, they're not telling you the things that you shouldn't be doing. Here are a few things that, even if you're doing everything right, will still cause people to click unlike and head over to your competitor.
1) Posting too frequently.
Sure, your content is good, its got everything you need to draw people in but you're posting way too many times a day! Once a day at the most (or twice if you have a large audience) is ample to get your point across. If you start inundating peoples news feeds they'll unfollow without seeing what you've got to say. Its invasive. Stick to a schedule and remember that less is more.
2) WRITING IN CAPITALS!
This isn't an urban legend; people really do take offence at writing in capitals, apart from that, its also difficult to read. Write in the correct case or risk appearing like you're shouting at your readers which will do nothing apart from encourage them to unfollow you.
3) Being negative.
Its encouraged that you should be real through your social media posts but if being real means a constant stream of bitching and whinging at everything the world has to offer then you're not going to win any fans whatsoever. People take to social media to see whats going on in the world but also as a means of escapism. NOBODY wants to see your daily gripes, it doesn't make people feel good and its unnecessary.
4) Tagging everyone on your friends list in your sales posts.
This is the worst and not only will it lose your business Facebook followers, it could also lost your Facebook friends too! Nobody needs to be including in a post with 100 or more other people, the notifications are annoying and its as good as spam. If you cant get exposure based on your own merit, then you don't deserve it. Make your posts good so that they appeal to your target market rather than relying on the friends list of people you know.
Often you're so busy doing everything that you should that the shouldn't stuff which has just as big an impact on your following, is missed.
