In case you missed the social media headlines this month, here are the most important things marketers should know.

Snapchat: Shopping With Selfies

Face swap? How about face shop? Brands on Snapchat can now sponsor a photo lens that allows users to buy products or learn more without leaving the app.

Adidas, Clairol, King and STX Entertainment are the first to use the new Shoppable AR feature, which was announced on Wednesday.

Instagram: Focus On Friends

Facebook’s Instagram announced another Snapchat-like feature this week—a special image that when scanned, allows someone to follow a specific account. Dubbed “Nametags,” the feature is similar to Snapchat’s QR codes.

Meanwhile, portrait mode in Instagram Stories just received a new mode called “Focus.” Snapping a photo in the new mode will keep the subject in focus, while slightly blurring the background. The new feature is available on iOS at launch, and rolling out to select Android devices beginning Wednesday.

Users can mention other accounts with the new “@mention” sticker, which works the same as tagging someone in the caption. While advertised for friends, the implications for influencer marketing are obvious.

Facebook: Play, Pay And Privacy

Facebook is testing a new “playable ad” format that would allow users to try a game before they install. Developer Miniclip was one of the developers who tested the ad in beta. Facebook will provide more details about playable ads during its annual F8 event May 1.

Would you pay for Facebook? During his testimony before the US Senate, CEO Mark Zuckerberg said that users are not able to opt out of being targeted for ads, saying, “that would be a paid product.” He also said that there would always be a version of Facebook that is free—causing many to speculate as to whether the social network will adopt a tiered level of membership in the future.

As the GDPR deadline looms closer, Facebook has updated its terms of service but it’s clear what the company wants users to move along. When asked to accept or decline Facebook’s new terms of service, users will see a big blue button marked “I accept,” while “See your options,” including the ability to decline the terms is smaller and less conspicuous.
