According to professional book writing services, you should aim to sell at least 5,000 and up to 10,000 copies of your book in one week. There is more to it than that, but where you end up depends on whose list you prioritize being on.
This is due to the fact that every list has its own unique collection of data and does not make use of the same thing. On the authority of affordable small business SEO services, nobody in the United States is able to find out how many books were purchased in a certain week. The process of compiling all of this information takes a significant amount of time for publishers. You simply cannot collect everything in time to compile a complete list of the week's best-selling items.
