The 22yr old fashion blogger who makes around $15000 per instagram post

Danielle Bernstein, the personal-style blogger behind We Wore What, recently told Harper's Bazaar that she can make as much as $15,000 from a single Instagram post.

The money comes from brands that want to get their products noticed by the 992,000 people who follow Bernstein on the Instagram.

Like many other fashion bloggers, Bernstein posts seemingly casual snapshots of her daily outfits, along with information about how to buy the clothes and accessories that she's wearing.

What her followers might not guess is that many of those posts are the result of negotiations with fashion and lifestyle brands who might ask her to not include any competitors' products in the same shot, or even in any other Instagram posts that week. They're willing to pay a high price tag for that. According to Harper's Bazaar, brands spend more than $1 billion each year on sponsored Instagram posts.

The exact amount that companies pay is directly connected to the number of followers that an Instagram user has. When Bernstein hits the million-follower mark, she'll be able to charge even more for a single post.

Harper's Bazaar explains: On average, if you have hundreds of thousands of followers you can make anywhere from $500 to $5,000 a post, but if you have upwards of 6 million followers, your fee can be $20,000 to $100,000 per shot.

Though Bernstein wouldn't say how much she earns through blogging and sponsored Instagram posts, she did admit that "it's more than I could have ever imagined [making] as a 22-year-old."

She added, "I fully support myself, and it's in the mid-six figures. I save; I invest; I'm trying to be smart about it all and learn as I go."

Recent Study suggests Popular brands are more active on Instagram than Facebook

A recent study from New York based research firm L2 suggests that an increasing number of popular brands are posting more on the Instagram than on Facebook.

Both brand and social media users are slowly preferring easier-to-use and "less boring" Instagram.

L2 also said that around three million US teenagers stopped using Facebook between 2011 and 2014, while "the same cohort now cites Instagram as their most important social network", according to a Benzinga.com report.

Taling about brands- From sportswear to beauty and consumer electronics, brands of all sorts are instantly attracted by Instagram's organic reach. L2 pointed out that, when it comes to beauty brands, some cult color brands like MAC, Urban Decay and Nyx depend on their ardent fan bases for Instagram love, while others, like Proactiv and Estee Lauder, push celebrity influencers to boost growth and engagement.

According to a research and advisory firm Forrester, the Top brands' Instagram posts generate a per-follower engagement rate 58 times higher than their Facebook posts -- and 120 times higher than their Twitter posts'.

Facebook bought Instagram in April, 2012 for a billion dollars, and Instagram is now valued at a very large $35 billion.
