I've noticed that invariably when you use the Adsense Preview Tool in a page, the Adsense spider will come to your page within seconds. I was wondering about adding an http request to the adsense preview tool page, from the server side, each time I save a new page in my site. Of course the idea is to get better targeted ads. What do you think?
All I have to do on my main site is view the page. Within a minute Adsense starts serving targetted ads. Since viewing the page for proper rendering is a normal part of putting up a page... going throw any extra steps to get Adsense to crawl it is redundant. YMMV
