Using Spinbot you can instantly spin (or rewrite) a chunk of textual content up to 10,000 characters in length (or about 1000 words), which is much longer than an average website or freely-distributed article. With a single click you can turn your old blog post or website article into a completely new one, thereby doubling the payoff you get in return for the time and energy you have already invested into creating quality website content. Spinbot is lightning fast as well as free, so there is potentially no limit to the amount of free web content that you can create using this tool.

Later I cleaned all my text with better spun (I didn't buy any article!), my ranking went up again, and with more backlinks I reached #1 and it is still there
