Facebook will stop advertisements appearing on pages containing sexual or violent content after a number of companies suspended their campaigns.
Marks and Spencer and BSkyB, the parent company of Sky News, were among those to pull their adverts from the social networking site because of concerns about placement.
It led Facebook to announce a tightening of its review process, preventing promotions from appearing on pages and groups which contain offensive content.
In the first three months of the year, 85% of Facebook’s revenue came from advertising – up 43% on the same quarter in 2012.
Advertisers paid a total of $1.25bn (£820m) to promote their products and services to the website’s reported 665 million daily active users.
