It is believed that since Facebook is running out of Ad Space, it is looking at testing ads in groups. The aim is to make the maximum out of its 500 million users who are still left untapped. It claims to reach its maximum advertising capacity by Mid-2017. Even the workplace initiative is believed to be one of the channels to serve ads. Techcrunch received confirmation from Facebook that as a part of the trial, desktop and mobile versions have been rolled out.
This update can be a boon for advertisers, as groups are a good way to reach out to the consumers. In time, we would know what the users have to say about this, as groups were one of the few ad-free spaces on Facebook.
