If you're a blogger and you're displaying AdSense ads on your blog, don't forget to view the permalink page for each new blog entry you make. This “primes the pump”, so the speak, by causing the AdSense crawler to come fetch the page so that the first visitor who actually view the blog entry via the permalink page (which will happen when other blogs start linking to it) will see relevant ads. A small thing, but trivial to do — so click the permalink immediately after you've posted an entry and get the crawler to visit.
