Until now, Facebook was only showing targeted ads to its users, but now it says it needs extra data to make ads better.
The new change will impact anyone using the internet, even if they’re not signed up to the social network.
It’s part of the expansion of Facebook’s Audience Network, which will allow publishers and developers to reach more people through Facebook advertising.
They’ll do this by tracking people’s browsing behaviour and collecting information about all internet users, using the ‘like’ button and codes on other websites.
Facebook’s ads and business platform vice president Andrew Bosworth told the Wall Street Journal: ‘Our buttons and plugins send over basic information about users’ browsing sessions.
‘For non-Facebook members, previously we didn’t use it.
‘Now we’ll use it to better understand how to target those people.’
