Now, my advice for Pinterest: As far as my blog goes, I only “pin” my own images when I feel like they are “pin” worthy – meaning they might cater to a Pinterest user. On Pinterest, people love a good “how to..” or “10 ways to..” type post. I do not pin every post I write.
Instagram: I just post to Instagram on the fly in my spare time. Sorry, not much depth or insight here. I have been trying to post images from my blog more, but mostly, it is just a collection of my life in images.
Google+: Ekk.. I know I have said this before, but I am still learning the ins-and-outs of Google+. I try to promote my blog posts through this outlet, but honestly it has been last on my list and gets neglected. I need to be better, but priorities people.. priorities.
I hope this helps you and answers some of your questions! Feel free to leave me comments or ask me questions below 🙂 I would love to hear from you.
