I've seen a ton of books/websites with "bestseller" or "bestselling author of __" on it.
But it ONLY counts with The Powers That Be (your agent, other publishers, and Publisher's Weekly) when it's a "USA Today Bestseller" or a "NYTimes Bestseller".
Both of which happened with one of my best friends. Her sales numbers were that good, now her publisher can boast about it on her new covers. Most cool!
A couple of my titles reached the high middle numbers for a week on the NYT list, but my agent and publishers haven't yet put that declaration on the covers. Apparently there is a tipping point that has to do with sales, ranking, and duration time on the lists.
When a vanity, e-book, or self-pub book has that on the covers I dismiss it outright as promotional hyperbole by a too optimistic or inexperienced author. In those situations, selling a hundred copies makes one a "bestseller" but not in the eyes of the industry.
I have a couple of books that are "top sellers" on Amazon. They were in the #1 spot on their release days, and one has remained in the top ten for its category for months now. I've never bothered mentioning that on my website or blog, because I don't think it's all that impressive. If/when I DO hit the NYT list, THAT will be an accomplishment worth talking about.
One of those promotion-minded writers tried to get a free air ticket to a convention in another state, sending the con committee a fat press release about her amazing literary accomplishments. (Apparently overlooking the fact that Google can be inconvenient to such goals.)
When they saw that her books were from PublishAmerica and Lulu, had zero sales on Amazon (despite those nifty 5-star reviews!), and zero sales to any commercial publisher, the committee said thanks, but no thanks, then brought in a
pro writer.
Gory (but amusing) details.
I looked her up on Amazon again. She's branched away from PublishAmerica (her 89-page epic is now only 14.95!!) and writes exclusively for Lulu and whatever she can convert to Amazon's Kindle format. No word on sales to commercial houses, though.
I give her credit for getting away from the PA machine, but she's got more nerve than a bum tooth for the wildly exaggerated promotional declarations.
Sadly, she is not an isolated case.
