Frequent posts sometimes can play a bad joke with you. Of course it’s very essential to stay always in touch with your audience, however they might feel that you’re too obtrusive and stop following you. There is no any rule how often you should post your news, but it’s advisable to limit the number of your posts with only two a day. You can experiment with the frequency of posts to look at the reaction you get.
Keep your audience intrigued, if you do so there’re more chances that you can really succeed, if not you’ll have to admit that your campaign is not efficient enough and you need to reconsider it. Remember that finding a right stop isn’t the end, you will have to adjust your posting policy once your audience has grown. Post optimization is endless.
