LONDON (Reuters) - Consumer goods giant Unilever
With big brands advertising more on social media sites like Instagram and Facebook
The practice of buying followers risks eroding trust and therefore damaging one of the fastest-growing areas of advertising - the billion-dollar-a-year market now known as "influencer marketing" - and Unilever says it wants it to stop.
Its chief marketing officer, Keith Weed, will pledge on Monday that the maker of Dove soap and Hellmann's mayonnaise will never buy followers or work with influencers who buy followers. It will also prioritise social media platforms that take action to stamp out fraud and increase transparency.
"Trust comes on foot and leaves on horseback, and we could very quickly see the whole influencer space be undermined," Weed told Reuters. "There are lots of great influencers out there, but there are a few bad apples spoiling the barrel and the trouble is, everyone goes down once the trust is undermined."
The announcement comes four months after Weed made waves by threatening to pull investment from digital platforms such as Facebook and Google if they did not take steps to improve consumer trust and eradicate "toxic" online content.

PAYING FOR BOTS
Fake followers are often machine-generated profiles fuelled by "bots" or software applications that mimic human behaviour. They can "like" or comment on posts, giving the impression of popularity or engagement.
It is hard to pinpoint how prevalent the practice of buying followers is, but Weed said he has heard estimates that as much as 40 percent of influencers have been involved at some point, sometimes accidentally.
Peter Stork, co-founder of influencer marketing measurement firm Points North Group, says all companies he has analysed have fallen prey, including Unilever.
Besides misleading consumers, Storck says bots waste money, since brands are spending to reach eyeballs that do not exist, making it even harder to gauge return on digital investments.
"They don't know what they're getting for it, and they spend a lot of money giving impressions to bots," he said.
A study last year by Rakuten Marketing said some UK marketers were willing to pay celebrity influencers more than 75,000 pounds for a single Facebook post. A "micro-influencer," with fewer than 10,000 followers, might earn as much as 1,500 pounds, it said.
Weed declined to say how much Unilever paid its influencers. He said the company does not now have "a major issue" with fake followers since it already cleaned up its stable of partners.
Unilever spent 7.7 billion euros (6.72 billion pounds) on marketing last year. Of that, only "tens of millions" was on influencer marketing, but Weed predicts that will grow.
