Bookbub claims to have huge exposure for advertising and to provide a great return for authors, if they will invest in and are approved for their platform. We have found that their advertising is overpriced and that the exposure is not as great as Bookbub claims. Very minimal return for the investment. Considering the large numbers of consumer readers that Bookbub claims (in excess of 800,000) to give authors access to, the return on advertising investment should be exponentially greater. Advertiser beware, as there are much better platforms for advertising that will offer much greater return. Unless Bookbub makes drastic changes, and is more honest with their advertising reach, they will continue to lose readership and clout. Things are definitely not as they appear in the world of Bookbub advertising.
