As if there weren't already enough places through the entire Facebook network to place ads on, Instagram unviels new ad format in the explore tab.

Instagram announced today that it is introducing ads in its Explore tab, the section where users can browse content and discover new accounts based on their interests.

The company said it will be rolling out the ads “slowly and thoughtfully” over the coming months. Instagram’s Business Product Marketing Director Susan Bucker Rose told TechCrunch Instagram will first test the ads to promote IGTV (Instagram’s long-form video platform) before offering the ad unit to a “handful of brands” over the upcoming weeks.

Instagram’s advertising business is growing faster than Facebook, and the site is experiencing more user engagement growth than it’s parent platform, too. It’s no surprise the company is looking to take advantage of that growth by finding new ways to generate ad revenue. Putting ads in the Explore tab will give Instagram advertisers a new inventory area to reach users beyond their feeds.

Initially, Instagram will only show ads to users after they’ve engaged with Explore content. Ads will be eligible to show to users once they have tapped on a photo or video within Explore. Then, Instagram said, the user, “May begin to see ads as part of their browsing experience just like in the main feed.”
