I currently have a book on Amazon which was released just recently. The link can be seen below for my book Thailand for Couples" Travel Guide. I am trying to get reviews and I am using Goodreads giveaways, listed my book Netgalley and in 5 weeks I have scheduled to use Reedsy book review service as well. I currently have 1 rating but not a customer review on amazon US and and 2 reviews on Amazon UK. I would like to explore the options of PPC on Amazon because my goal is to get ranked higher in order to achieve more sales. I have used a marketer already who has given me categories to input for my book in different countries. I need an expert who can advise if I can start using PPC now with not much reviews and if so which PPC options to use. If you know other ways to get more reviews as well that would be beneficial but the main answer I am after is regrading PPC.
