Example.com are you sure you haven't done some setting wrong? Most play around with code copy paste trying around could of dropped example.com in the Iframe or something!?
Or is Instagram playing a spookey on you! That is just weird. What domain extension are you using?
I Start to think it is absolutely essential to have a aged domain as well as aged instagram accounts nowadays it seem just as important with both.
Iam not a frequent user of ogads but use affiliate products and etc. more quality and half automated for mainly growth. But also rely on follows as in this journey. It is a lot of work. I manage 50 or more solid accounts, earnings even out over the month to 5-10 $ day per account, give and take.
Every account includes a lander page. A blog. An Instagram account. A twitter account. A Facebook page and google plus page. Plus some Web 2.0 s mixed in there.

Also started to explore Pinterest now.
I spend loads of time interacting with comments comments manually! And a strong niche.
I also collect emails and are using ogads in email offers sometimes. But then I have all power and can design a really cool responsive email that kicks ass.
So it would be hard to nail it down to just Instagram for me as I have organic growth from search engines aswell.
It is a pyramid that takes more than 2 people's attention full time, like running a farm. Feed the cows. Get up in the morning. And then milk them every morning. Hehe If they are happy and taken care of. They give more milk!
The more I design and share post the more I make. Heavy repetitive actions....
I think I will drop 25 of the 50 soon and concentrate on a smaller set.
