Whenever someone uploads a review for a book onto the Amazon.com site in the United States, the review soon appears on all the other Amazon book sites worldwide. But, if a review is uploaded using any other Amazon site such as the one here in the UK – Amazon.co.uk, the review in question only appears on the site it was uploaded to.
I can give you an example.
Last week my science fiction novel “The Seventh Age” received a review from a prominent author on ancient Egypt – Robert Bauval. Only those who purchase their books using Amazon.co.uk in England are aware of it and may be influenced into purchasing a copy because of his review.
Because of the way Amazon’s review system currently works, potential customers in the US and elsewhere, unless they happen to go to the UK site will remain ignorant of Mr. Bauval’s review.
The two reviews that were posted on Amazon.com in the US are common to both, while Mr. Bauval’s review only appears on Amazon.co.uk. Surely if any reviews posted on Amazon.com can automatically appear on all the other sites, then reviews posted on non-US Amazon sites should be able to be seen on the Amazon.com site in the US, after all, it is Amazon’s main site. At the bottom of the UK Amazon page, there is a simple piece of hypertext which says if you click on it you can read the US reviews for the book you are interested in. Why not place something similar on the Amazon.com page for reviews posted elsewhere like the Amazon page here in the UK?
I am quite sure that you the readers will appreciate how much we writers rely on reviews to persuade potential customers to buy our product. When a prominent author like Robert Bauval lends his name to a book in the form of a favorable review, and that review never gets seen outside the country in which it was posted, the number of missed sales begins to mount up. For those writing the reviews, having to post them on more than one site is plainly ridiculous, not to say time-consuming.
