The easy reply is that it means various things to totally different folks, however I’ll elaborate.

In case you are a buyer and you’re shopping the “Product Particulars” of a particular guide, you might interpret the sales-rank to be a measure of the recognition of that guide. The decrease the gross sales rank quantity, the extra fashionable the guide as decided by the variety of current gross sales of that title via the market. That is true typically, however should you 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 For instance, a guide with an sales-rank of 100,000 that has solely been launched and marketed on for a number of days could also be highly regarded within the close to future and attain the highest ten. That it is just ranked 100,000 proper now’s a little bit misleading as a result of the timeframe over which this rank was decided just isn’t actually lengthy sufficient to measure the true recognition.

To a bookseller, the sales-rank is very often correlated to how shortly a specific title would possibly promote. A guide with a really low quantity rank is perhaps anticipated to promote inside minutes or hours of itemizing, and a guide with a gross sales rank of 4,000,000 would possibly take a number of years to promote. The analogy is ceaselessly utilized by booksellers when they’re scouting for books so as to add to their stock. If a bookseller finds a guide that has an internet worth of $10, an gross sales rank of two,105,878, and he/she is confronted with shopping for it for $4, they’re apt to go, but when the gross sales rank had been 45,017, it would instantly be a guide value including to their stock.

In scouting for books, I do have a look at the gross sales rank for increased priced books as a result of I don’t wish to stack a number of firewood on my cabinets, however it’s definitely not the measure I exploit for many guide purchases. The scientist in me needed to know extra, so I compiled the rank knowledge for 1000’s of the books I’ve offered, utilizing rank at each on the time I bought them and on the time I offered them respectively. Being an engineer, I needed to acquire and torture the info to see if there was any correlation between the gross sales rank and the time it takes to promote a guide. Certainly there may be, at the very least in my expertise, and doing a curve match to the info yielded a correlation coefficient of 0.93. The wellness of match of the info is especially obvious in a semi-logarithmic plot.

So, you see, there’s a which means to the gross sales rank.

For the guide purchaser it’s a measure of a guide’s recognition.

For the bookseller, it’s a measure of how shortly a guide would possibly promote and or whether or not or not the guide would possibly simply be firewood.

For the engineer, it’s only a bunch extra knowledge that may be tortured right into a confession of types.
