Jan Notzon asked Molly Ringle:

I was intrigued by you're mentioning hosting giveaways by yourself on social media. Is it unkosher to ask how you go about that? Thanks

Molly Ringle Hi! I've found Instagram to be one of the best places myself, since "bookstagram" (readers posting about books) is a huge trend there, and there's often cross-posting to TikTok from it. It does help to already have a decent Instagram presence or following, but even if you don't, using relevant hashtags can bring people to your post—like #giveaway and whatever the genres and subgenres are for your book.
.
For Instagram or any other social media platform, I usually have people comment and tag a friend, and/or share the post to their own feed, to enter to win. Here's an example of one such post I made:

This could all be done on, say, Facebook too - wherever you get the most engagement.
