Following another quarter that saw marketers pull back on their ad spending, Meta today announced it’s increasing its ad load on Instagram with the launch of two new ad slots. Amid a slew of product updates for advertisers, including a music catalog for advertisers and a new ad format for Facebook Reels, the company said it will now allow advertisers to run ads on the Explore home page and in profile feeds.

Meanwhile, though Instagram Reels began rolling out 30-second ads globally last year, followed by Reels ads on Facebook earlier in 2022, the new format now being tested will involve shorter ads on Facebook Reels, specifically.
