Digital Advertisers face problem in getting the ads approved by Facebook because of the 20 % text policy. This post is for the beginner advertisers.
According to Facebook
Adverts that have more than 20% text in their image won’t be approved to run on Facebook. Too much text can look like spam and make people think that your advert is low-quality. Make sure that you use the headline and body of your advert to tell people more about why you’re advertising and what you want them to do.
