Because I'm in charge of posting the nominated books on the
GOLDEN BOOK AWARD CONTEST page, I've been copying and posting a lot of book links.
I noticed that a majority of authors are posting and sharing their long Amazon book's links on social sites that tells tremendous amount of information to the algorithm they use for monitoring.
When most authors search for their own book’s link to post it on social sites, usually they go to Amazon, type in the title of their book, click on the book, and copy that page’s URL.
Posting and sharing the long URL of your book is a big mistake.
The long URL contains a time stamp and a marking when you search for your books. This number tells amazon that at this particular time, your book was searched from your IP address.
Don't post this type of book link
Delete the red part
Post the short link on social sites and share with fans
Search for your book by typing your book title in Amazon search and copy the long URL. The URL will contain ten numbers which will change when you click off from the site, sign back in and repeat the search by typing your book tile in search. The ten numbers in the URL will be different every time you repeat the search.
Using a long URL on a search will leave a trail that goes back to you because it contains your IP address.
I can't say that it means that everyone who clicks on the long link, buys the book and leaves a review is going to have their review removed because I can't prove it, but I strongly believe that it could greatly increase the chance of having those reviews removed.
Therefore, the link that you would want to send or post to your fans so as to ensure that there are no identifiable markings, or tags, that will connect you to the link, just use the shortened link that includes the title/subtitle URL and the ASIN such as this link to my book:
