auxiliary Google, that dominates a tellurian digital-advertising market, and a far-reaching operation of other online ad specialists.

“Publishers and app developers have some users who aren’t Facebook users. We consider we can do a improved pursuit powering those ads,” pronounced Andrew Bosworth, clamp boss of Facebook’s ads and business platform.

Facebook disclosed in Mar that about 1.65 billion people now use a site any month. According to a International Telecommunication Union, a sum of 3.17 billion people used a Internet globally in 2015.

To date, Facebook has usually showed ads opposite a Audience Network to Facebook users, targeted formed on information a association has collected about a users’ tastes and behaviors.

If widely used by publishers and media companies, a new underline could meant Facebook will have a palm in offered and fixation a incomparable apportionment of online ads, that could assistance it beget additional revenue. The association generated over $17 billion in ad income in 2015.

Facebook gets an vague cut of a income from ads it sells by a Audience Network. Typically, a association takes a roughly 30% share and gives a rest to publishers, according to people informed with a matter.

Some publishers competence be heedful of handing some-more of their ad sales operations to Facebook. Many already rest heavily on a amicable network to beget trade for their sites, and some now post calm directly to Facebook by Instant Articles.

Non-Facebook users will be means to opt-out of “interest-based” promotion from Facebook, a association said. Facebook members will also be means to opt-out of saying ads outward of a amicable height formed on their on-Facebook interests.

Marketers shopping promotion opposite a Facebook Audience Network will have a choice to not uncover ads to non-Facebook users if they wish, though that ad space will be enclosed by default, a association said.
