I often share my posts via Facebook, but there are few problems. First of all when I share post there is a title of my website. I dont need that. Second there is no text announce. Third there is no author. I found this (http://www.technohalf.com/2015/01/how-to-add-facebook-open-graph-to-blogger-blog.html) tutorial, did everything but it still didnt helped me solve this problem. I still get error from Facebook Insights.
