I used to do this to keep my feed concise, only showing posts my friends interacted with (I don't follow any pages), but recently it has become more or less useless. Facebook decided that it wanted to show content that might catch interests by throwing it under the header "Suggested for you". Some time before that, I can simply dismiss it and it won't show again for some time, but right now it showed every day, and I can't dismiss it at all. The most "suggested" page in my feed right now is a fan page of One Piece's author, which posted memes or content related to the manga despite I not showing interest in it, and I can't make it perish.
