I looked up the official definition of best seller: A best seller is a book that has been sold to more than just the author's friends and family and the publishers want to promote that fact.
Wouldn't it be nice if that really is the definition, lol!
My opinion is that Bestsellers in paperback/hardback are, and should be, based on sales. For eBooks listing. But the term is most strongly associated (by the average consumer) by total sales.
Anyway, if you're going by sales figures; New York Times, USA Today & Guardian (UK paper hardback only) are pretty much the final word on the old skool Bestseller (they get all their data from Nielsen's I think).
But with eBooks that all changes. We have Kindle, iBook and Nook Top 100 Bestseller lists for eBooks - books which sell a lot, but still will not make the NYT & Guardian BS lists.
All of my books have made BS lists in Kindle UK (and US). I made the Kindle UK Top 100 with one. Does that make that eBook a Bestseller? I say yes, but no doubt many would say a resounding no.
From Wikipedia (a semi reliable source of knowledge);
A bestseller is a book that is identified as extremely popular by its inclusion on lists of currently top selling titles that are based on publishing industry and book trade figures and published by newspapers, magazines, or bookstore chains. Some lists are broken down into classifications and specialities (number one best selling new cookbook, novel, nonfiction, etc.). The New York Times Best Seller list is one of the best-known bestseller lists for the US. The New York Times Best Seller list only tracks National and Independent book stores; it does not include sales from Internet retailers. In everyday use, the term bestseller is not usually associated with a specified level of sales, and may be used very loosely indeed in publisher's publicity. Bestsellers tend not to be books considered of superior academic value or literary quality, though there are exceptions.
Lists simply give the highest-selling titles in the category over the stated period. Some books have sold many more copies than contemporary "bestsellers", but over a long period of time.
In the United Kingdom, a hardcover book could be considered a "bestseller" with sales ranging from 4,000 to 25,000 copies per week, and in Canada, the rule of thumb is 5,000 copies sold.[5] There are many "bestseller lists" that display anywhere from 10 to 150 titles.
