Facebook's mobile audience in the US and the UK has increased almost 20% according to the social networking giant.
The firm used the announcement to show the social network brands appeal for other brands and mobile advertising professionals as consumers go mobile during the summer months.
The social networking site's CEO, Mark Zuckerberg, also revealed mobile advertising accounted for 30% of Facebook's overall ad revenue in the first quarter of the year, not bad when mobile advertising was only launched last year on the Facebook mobile app.
While Facebook revealed Americans had increasingly taken to using its mobile site, leading to an 18 % rise, it was us Brits who were really leading the way, with a 22% surge in mobile users in June compared to this time last year.
With more and more customers looking to their mobile or smart device rather than logging on to a desktop, the shift to a mobile focussed marketing strategy could be crucial for brands looking at digital marketing opportunities.
Facebook regional director for Britain and Southern Europe, James Quarles, said: We see this as a fantastic opportunity with empirical evidence of people staying engaged on mobile phones and using Facebook.
"As people are away and on holiday, it provides a different opportunity for brands to think differently about Facebook."
Brands who claim to have seen success in the use of Facebook's mobile ads so far include Pimms - which launched a Wimbledon focussed ad campaign - and Cornetto, the popular icecream brand.
