You can force more frequent spidering through a variety of black, grey, pink and white hat techniques. There are literally hundreds of ways to get more backlinks to your sites if the purpose of those backlinks is to increase spider activity and not to build PR. The more times you get your pages into Google's pile of pages to be spidered then the more times you will be spidered, mathematically speaking.
