Irrelevant and/or spam comments: If an influencer has a ton of comments, it's easy to assume that their followers are active. Look through a few photos and scan the comments. If the comments are clearly irrelevant or gibberish, they're from fake followers.

Here's the scoop on what influencers are pulling in: Instagram influencers with fewer than 100k followers earn around $200 per post. Instagram influencers between 100k – 300k followers may expect to earn around $600 per post. Instagram influencers with more than 1 million followers earn more than $2000 per post.

So, if you had 500K followers, you could estimate that you'd make anywhere from $2,500 to $12,500 from sponsored posts alone. Remember that these figures are just for sponsored posts. Many influencers with followings this big are also selling their own products or engage in affiliate marketing.
