In the past week or so, Facebook has revealed how many active advertisers it has on both Facebook and Instagram.

Facebook has surpassed 3 million after just passing the 2.5 million milestone 6 months ago. Instagram has surpassed 200,000 after only making ads broadly available in the fall.

WebpageFX has put together a helpful infographic (via AdWeek) looking at ad specifications and dimensions for Facebook and Instagram across ten different objectives. These include: clicks to website, website conversions, page post engagement, page likes, app installs, app engagement, local awareness, event responses, offer claims, and video views.

Take a look.
