The truth is that you get a lot of different answers on this, and it mostly depends on the influencer as well as the platform and follower size. Here's what you should expect from the most common strata. 

NANO INFLUENCERS (Under 10,000 followers, more than 1,000)
- They can do this for free, or charge as much as $100. On average, it's $10 to $50. 
- You might have to reach out to them individually as many platforms won't work with them.

MICRO INFLUENCERS (Between 10,000 to 100,000)
- They charge as much as $100 to $500 per post, with visuals and YouTube posts being more common. 
- These are where you might be able to start finding them on Influenster. 

INFLUENCERS (Between 100,000 to 500,000 followers)
- They charge $500 to $5,000 per post. 
- Many are agency-represented. 

MACRO INFLUENCERS (Between 500,000 to 1 Million followers)
- They charge between $5,000 to $10,000 per post.
- Almost all of them are agency represented and are major names in their fields. 

MEGA INFLUENCERS (More than 1 million)
- These guys almost always charge more than $10,000 per post. It's not unheard-of for prices as high as $30,000 for a single post. 
- Since these are generally celebrities, you will not find them on sites like Influenster.
