New Web site charts your Amazon Sales Rank

Here's another neat site for tracking the Amazon Sales Rank of any book: Charteo.us.

It has some features you won't find elsewhere, such as the ability to:

• Compare multiple titles on the same chart
• Embedding a chart in any page
• Navigate based on average sales rank. (Take the tour here.)
  

Use it without registration. The site's editor assures me that it will always be free.

Here's a snippet from the site's blog:

I hope curious authors and publishers wanting to track minute-by-minute performance of their books find these charts amusing or useful or amusing and useful. A little more time poking around different corners at the site may also help them pick the right idea for their next project by giving a sense of what is currently hot, what endures and what is in its way out.
