But influencer marketing is also unregulated and uncontrolled. Given the relative recency of its rise, at least in a digital marketing sense, there are no set rules around how you should go about it, which can lead to confusion as to how to find the right influencers, which numbers and data points you should trust - and, crucially, how much you should expect to pay for an influencer to post about your product or service.

The last point is where this new report from Klear comes in - to help provide more transparency in the influencer marketing process, Klear surveyed more than 2,500 different types of influencers across three major social networks (Instagram, YouTube and Facebook), in order to gain some perspective on what they're charging for sponsored content.

You can immediately see why more niche, nano-influencers can have more appeal - not only are they often more connected with their specific online communities, but they also charge far less than celebrities.

Of course, this data is not definitive - as noted, essentially there are no official rules or regulations in influencer marketing deals, and each individual will charge differently. But given the sample size, this is a fairly good indicator of what you can expect, which may help in your strategic planning. 

The best way to utilize influencers is to conduct thorough research on their output and their audience, then cross-match that against your own strategic objectives. If there's a clear merge between those you want to reach, and the audience of said influencer, as well as a fit in their presentation style,  then the opportunities will be clear.

Audience crossover is obviously more likely with larger influencers, due to the sheer scale of their reach, but the same may be possible in smaller groups. But it does require more research effort.

Either way, Klear's data may help in your planning - again, you can read Klear's full "2019 Influencer Rate Card" report here.
