After taking Xavier (my Siberian Husky for new readers) out to do his business, I had an idea that I would use each social media platform I frequent to hold giveaways conducive to the platform. For example:
My Instagram would have image-inclined giveaways.
My Facebook Page would have 'share this, comment, take a photo of yourself with book 1, answer this question, and sing a song while on your head' kind of giveaways.
My Tumblr would have 'reblog this and like this to enter' kind of giveaways.
Because I'm starting not to post the same things on each social media. Some days my Instagram is left alone while I frequent Facebook. At others, my Tumblr sees me reblogging everything in sight, sparking up conversations with other writers and readers, and at others my Facebook sees me sharing everything I can.
Even my Newsletter would have 'subscriber-only' giveaways right through emails.
