New figures from ComScore place Facebook firmly as the biggest online advertising platform in the UK.
The number of ads on Facebook is reported to have grown 33% in the last year.
The social media giant is reported to have served 19.7 billion ads in the UK during May this year – almost four times more than second-placed Microsoft.
Google Sites managed to reach third place on the list with its 2.68 billion ads, beating both eBay (2.71 billion) and Yahoo Sites (2.4 billion) by an inch.



Facebook is reported to be ditching the ‘become a fan’ option, instead asking users to ‘like’ a brand.
The newest social media developments are providing more opportunities for businesses to engage with their online audience.
Statistics from last year showed 82% increased usage of social networking sites. The Nielsen Company report also shows that together with blogs, social networks are the most popular online category ranked by the average time spent online in December 2009.
