a following isn't the same as showing those people you uploaded something new. its easy to friend someone, you have to keep putting in their faces all the time. i find IG doesn't bring in the traffic though, unless we can add links to pictures now. you shouldn't be generating any visits, you should be ignoring your IP.
on facebook you have to be careful, they are cracking down on stuff, just today i learned that if a group leader removes your post, they keep track and may ban you from using facebook or parts of it. and if your blasting the same image to a lot of groups fast, they can see that as spam - and erase your posts and ban you. so when doing it, do different ones, and don't do a ton in a day.
the post and pray method rarely works.
also bots ignore you if you haven't posted anything new in a very long while. if your very intermittent, and your not always stirring the pot, it will ignore. google also looks for you on places like social media, so if your not really posting to a public place, and your wall is private, or the groups are private, it won't help you much.
you can still post it to your stream, twitter and pinterest too.
