If you have a business account on Instagram, you are already familiar with Instagram trying to tell you that you should “boost” your posts. While it might sound like a great idea to get your post seen by an additional 4000 people for a mere $5, I highly advise against it.
Yes, I have tried to run a few of my posts as ads in hopes to gain followers. The result after spending a few hundred dollars was 0 followers gained. Yes, ZERO. I was not frustrated about it because that was the result I was expecting to get.
If you see a post that has a word “Sponsored” at the top of it, you are very unlikely to hit the “follow” button. That’s the same way other people think when they see your own sponsored post.
Even if your post was selling an amazing product, the likely outcome would be a sale of that product. Following the page that posted it, would be the last thing on my mind. Instagram hasn’t figured out the way to display paid posts in a way that could bring in potential followers. You will not gain followers, you will only gain likes, but that’s not what we are here for.
