I create hundreds of pages. Put a few sentences of unique content on each. Arrange them such a way that different ones will get different amounts of pagerank based on their link structure. I let them soak for a month or so and measure their pagerank. The best way to do this is count the number of times gbot crawls each page. Higher pr pages get crawled more often.
