Under the targeting tab, you can add accounts, hashtags, and locations.
When choosing target sources, the best thing to do is ask yourself:
“Who are my potential customers?
Where are they now?
What other Instagram accounts do they follow?
What hashtags do they use?”
Think to yourself: “Why would people from that source want to follow my account?”
The answers to these questions should determine which growth targeting sources you choose. When you pick accounts to follow, make sure they post similar content to you.
