You couldn't help but be nosy.

We're often curious about just how much our favourite social influencers rake in from working with brands - as soon as we see that #ad, we begin to wonder just how much we could make from promoting beauty or diet products online. Well, Instagram scheduling company HopperHQ has spilled the beans on who's earning what and its report makes for very interesting reading. It's revealed that beauty blogger Huda Kattan is the top influencer worldwide when it comes to Instagram earnings.

The Dubai-based blogger has 20.5 million followers and earns a whopping $18,000 per sponsored post - not too shabby. The influencer rich list also shows that fitness blogger Jen Selter takes home $15,000 per post and Youtuber Zoella gets $14,000 per post.

The research also revealed that sponsored Instagram posts are becoming more and more common. One in twenty Insta users now monetise their feeds, with sponsored posts increasing by a third across the platform in the past two years. Interestingly, HopperHQ estimates that just one in five of all sponsored posts on Instagram are marked clearly as being paid for.
