www.read-reviewed.com to Goodreads (and Amazon).
The book was already found via their search option and I only needed to click on a link to 'claim' the book's title. The next day Goodreads confirmed the book was allocated to my account and I posted the book's description and the cover image. Does it increase sales to be on Goodreads? If anyone stumbles across it on the site, they can buy it via a link to Amazon - Goodreads is owned by Amazon. It doesn't hurt and it only takes five minutes.
