Facebook on Friday said it's testing new advertiser "topic exclusion controls" to help address concerns marketers may have that their ads are appearing next to topics in Facebook's News Feed that they consider bad for their brand.  

Why it matters: As Axios has previously noted, the chaotic nature of the modern news cycle and digital advertising landscape has made it nearly impossible for brands to run ads against quality content in an automated fashion without encountering bad content.

• Most advertisers buy ads on Facebook through an automated bidding system.

Details: The controls will help advertisers choose which types of stories they may want to bypass in Facebook's News Feed.

• For example, an advertiser can select a topic, like Crime and Tragedy, that they would want their ads to avoid, and Facebook's tech will try not to align that ad next to any stories related to those topics.

Yes, but: Some fear these types of advertiser controls will inadvertently push marketers away from placing ads around news, especially during breaking news.

• In the past, brands have created blacklists, or lists of words or websites to avoid when buying automated ads. But blacklists aren't foolproof and often inadvertently block quality news sites from receiving ad revenue.
• This filter presumably aims to be more precise than a broad blacklist of keywords but could determine whether ads appear next to news content.

The big picture: Facebook has committed to developing better industrywide solutions for how it moderates its content through an industry coalition called The Global Alliance for Responsible Media (GARM).

• This update is meant to address some of GARM's recommendations.

What they're saying: “Providing advertisers topic exclusion tools to control the content their ads appear next to is incredibly important work for us, and to our commitment to the industry via GARM," says Facebook VP Global Business Group Carolyn Everson.

• "With privacy at the center of the work, we’re starting to develop and test for a control that will apply to News Feed. It will take time but it’s the right work to do.” 

What's next: Facebook anticipates that the product development, as well as testing and learning in News Feed, will take much of the year.
