I have noticed lately people complaining about not being able to reblog a post they like.
When I noticed this a few years ago I started exploring and found out that on some blogs you have to actually select the comment button to get both the like and reblog button to come up.
If having likes and reblogs is important to you check your intended theme and see if these buttons show up automatically or if you actually have to select the comment button to bring them up. Your visitor may not know this and just leave without liking, reblogging or commenting.
I personally like to use the like button and so many times it isn’t there. Same with the reblog button. Having to find the comment button can also be difficult at times.
Check that your intended theme has everything you want.
