Did you know that you can only follow 5,000 people on Linkedin? Is it enough? This is one of Linkedin’s data that you probably did not know and that we have compiled for you.

– Every user has three free backlinks that will help him/her rank on Google with certain keywords.

– You can only follow 5,000 users, but you can connect with as many as you want.

– You are allowed to join 100 groups. Remember: you can not join 101, so you have to decide which ones are the most interesting for you. Anyway, it used to be 50 until very recently.
