The straightforward reply is that it means various things to totally different folks, however I’ll elaborate.
If you’re a Amazon.com buyer and you’re shopping the “Product Details” of a particular e-book, you might interpret the Amazon.com sales-rank to be a measure of the recognition of that e-book. The decrease the Amazon.com gross sales rank quantity, the extra in style the e-book as decided by the variety of current gross sales of that title by means of the Amazon.com market. That is true basically, however for those who actually wish to know concerning the recognition of a particular title, you additionally want to contemplate the publication date and the way lengthy it has been marketed on Amazon.com. For instance, a e-book with an Amazon.com sales-rank of 100,000 that has solely been launched and marketed on Amazon.com for a number of days could also be very talked-about within the close to future and attain the highest ten. That it is just ranked 100,000 proper now’s just a little misleading as a result of the timeframe over which this rank was decided will not be actually lengthy sufficient to measure the true recognition.
To a bookseller, the Amazon.com sales-rank is very often correlated to how rapidly a selected title may promote. A e-book with a really low quantity Amazon.com rank is perhaps anticipated to promote inside minutes or hours of itemizing, and a e-book with a gross sales rank of 4,000,000 may take a number of years to promote. The analogy is incessantly utilized by booksellers when they’re scouting for books so as to add to their stock. If a bookseller finds a e-book that has a web based worth of $10, an Amazon.com gross sales rank of two,105,878, and he/she is confronted with shopping for it for $4, they’re apt to move, but when the gross sales rank had been 45,017, it would out of the blue be a e-book price including to their stock.
In scouting for books, I do have a look at the Amazon.com gross sales rank for greater priced books as a result of I don’t wish to stack a variety of firewood on my cabinets, however it’s actually not the measure I take advantage of for many e-book purchases. The scientist in me wished to know extra, so I compiled the Amazon.com rank information for hundreds of the books I’ve offered, utilizing Amazon.com rank at each on the time I bought them and on the time I offered them respectively. Being an engineer, I needed to gather and torture the information to see if there was any correlation between the Amazon.com gross sales rank and the time it takes to promote a e-book. Certainly there’s, at the least in my expertise, and doing a curve match to the information yielded a correlation coefficient of 0.93. The wellness of match of the information is especially obvious in a semi-logarithmic plot.
So, you see, there’s a that means to the Amazon.com gross sales rank.
For the e-book purchaser it’s a measure of a e-book’s recognition.
For the bookseller, it’s a measure of how rapidly a e-book may promote and or whether or not or not the e-book may simply be firewood.
For the engineer, it’s only a bunch extra information that may be tortured right into a confession of types.
