Let us know which book you want featured in the smart ad (either with an Amazon link or a similar book retailer).
I recommend around 125 words and 2 to 3 paragraphs.
We show your smart ad on pages related to these authors to target the right readers. We recommend giving us at least 10 similar authors, and you can give us up to 50.
Let me know what type of readers you want to reach. Be as broad and specific as possible.
