These are the cases in which users become fans without knowing what that fan page is about, just because of the name or seeing a publication for example. There are times when it is easy to detect them because they are from a different country and other times not so much, for the First, the option of eliminating them is very good. If you are in any of these situations or know from your own data that you have inactive fans, I advise you to proceed to delete them. Delete fans from a Facebook Fan Page The first requirement is that you need to be an administrator of the Facebook page with which you want to delete those fans, any other role does not allow you to perform this action. Subsequently you have to know who those fans are that you want to eliminate , have them detected or a pattern by name/country to avoid eliminating those who are of quality. 

Analyze community growth data and search by dates when they became a fan of the page to be more precise. With this done, enter your fan page to the “Settings” part and Special Data  the “People and other pages” tab . There you will see all the people and pages that have become fans. fan page fan configuration It is time for you to look for those people (you get the dates) that you want to eliminate. You select them and go to the wheel on the right and choose the option "Remove from page likes" This is enough, it's that easy. As you can see, it also gives you the option to prohibit access to the page or assign them a role . How to detect poor quality fans The most appropriate way is with an analysis of the publications and through KPIs such as the reach or interaction rate, to study whether the increase in community due to a campaign, action or other external causes has a negative consequence. Also knowing well the type of user profile that likes is a good companion for this decision-making, when you realize that fans begin to arrive with a common pattern and out of the ordinary from the rest. Another option is to use the Facebook search engine with which you can know who has liked a page and the country in which they live, for example (this can also be used to spy on the competition and know what type of fans they have). To do this, change the language of your Facebook account and set it to English (US) . You go to the search engine and enter a command such that: People who like + the name of the fan page For example.

 For my Facebook page it is: People who like Daniel Rocafull In the case of adding a conditional such as where they live, the command would be: People who like + the name of the fan page + and live in + country/city. If I would like to see the fans I have who live in Argentina , I do the following: People who like Daniel Rocafull and live in Argentina search-facebook With this you can know the exact name of those fans you want to eliminate and get more to the point. You can also use it to find out the fans that you and your competition have in common ( People who like + the name of your fan page + and like + the name of your competition's fan page) The bad thing about this method of eliminating fans is that it is manual and on a page that has a considerable volume of likes, it can be very heavy, but at the moment there is no other option, or at least I don't know about it (if anyone knows, Leave a comment :D) I hope it helps you and if you apply it.
