One of the best ways to discover what kinds of photos Instagram really wants brands to post in order to keep fans happy is to look at its recommendations for Instagram ads:
-No heavy use of image filters as a way to mask the “reality” of a shot, and no text overlays are allowed.
-Brands cannot feature their logo in Instagram ads other than as a natural, non-obvious part of the scene.
– Images used as ads must be “true to your brand”, i.e. not shocking or cheesy, and no use of gimmicks.
-Photos used for ads should capture “moments”, not products. In other words, ads must not just be a shot of your product, but something more creative and inspiring.
– Ads should use ideas and take cues from the existing Instagram community, especially from popular hashtags.
