Last month, Facebook quietly dropped the 20%-text requirement for image. This requirement rejected all ads containing text overlaying more than 20% of the image.
Facebook last month also sunset the tool where advertisers could test the images for the 20% text rule.
Facebook image requirements now say that "images that consist of more than 20% text may experience reduced delivery." This recommendation applies for the ad placements:
- Facebook feed
- Facebook right column
- Facebook instant articles
- Facebook Marketplace
- Facebook search results
- Audience Network native, banner, and interstitial
- Message Inbox
Before the ads were simply rejected.
Facebook recommends advertisers to avoid spreading text all over the image and to make sure that most of the text that they use is in the body text instead of directly in the ad's image.
