Rather than the usual Facebook post about a magazine with a photo of the full cover of the magazine, zoom in and show something more interesting. The photo with this post is part of the cover of the current issue of Australian Gluten Free Life. While the whole cover looks terrific, this image could gain more traction on social media.
The best way to promote magazines online is to do so in a way that reflects well on your business. A photo of a full magazine cover will not differentiate your business. This zoom-in photo of what looks like an Iced VoVo is more interesting and tasty looking.
The more different your social media posts the more interesting for people connecting with you on that platform.
