The marketplace is forecasting Instagram to become the next big traffic generator. I just reviewed my traffic and Pinterest is now generating more traffic than Google for me. What has been your experience? What is your forecast?
I think it depends on your topics. Pinterest has always been my #1 referrer, because my Hubs are very visual, which makes them very pinnable. If I used Instagram as a promotional tool, they'd probably do well there, too, but since IG is now owned by Facebook, which is cracking down on unpaid promotional posts, I don't see it lasting as a good option.
