Here are a few PR tips I shared a number of years ago in a newsletter. Most of these tips still apply to getting you, your book, or your stories into major magazines.
I added a few updates to incorporate all the social networks out there. Note: Some magazines actually feature pins, tweets, or posts that share their content. These are generally featured in the upfront section of the magazine in or near the letters to the editor.
In addition to the possibility of being featured in the print magazine, you also benefit from sharing content from a trusted source. People are more likely to repin, retweet, or share your reshares.
