I have listed all the sites that you can use to promote your kindle book when you create a free promotion. Some of these sites allow you to promote paid kindle books as well but usually there is a fee involved.

I shall update this list as and when I find new sites or notice that old ones no longer exist for this purpose. If you are at a loss to know where to start I would recommended beginning with the website Author Marketing Club.

Hashtags

When promoting on Twitter remember to make the best use of hastags because this will help people who are searching to find your promotion.

Here are some useful ones to use:

• #eBook
• #BookGiveaway
• #Kindle
• #KindleBargain
• #FreeKindleReads
• #FreeKindlebooks
• #freekindle
• #freebook
• #FreeKindleBook
• #ReadThis
• #authorshelpingauthors

Google Plus Communities

UPDATE

Google Plus is being removed as of April 2019. It seems that there wasn’t the demand for it so Google is deleting it!  It was good while it lasted!

If you would like to check another website with more free and paid book promotion sites then visit https://blog.reedsy.com/book-promotion-services/. The Founder, Ricardo, sent me an email to let me know about some broken links in my list (thank you!) and also about his site – this is what he said “We went for a highly curated approach and a tiered ranking based on how useful each site can be.” Sounds good to me!
