Authority is slipping away from 'traditional' experts – and into the hands of celebrities. But is 'standing out' from a sea of information, products and ideas as simple as putting a famous face on a brand?

Launched in 2004, Yelp has grown to include more than 50 million businesses worldwide. And it’s transformed how people find a place to eat; we now rely on tips from internet strangers. But thanks to Yelp Elite, some of these strangers are more powerful than others. So who are these influencers?

With over 61% of people reading online reviews before making a purchase decision, it’s even more important than ever to separate the good ones from the bad. But with peer reviews and professional write-ups often having contrasting opinions, who should we trust – and why?

The authority figure has returned to a position of influence as a reaction to widespread consumer distrust - and people are turning to these informed experts for advice and information that they can rely on.
