I'm noticing that sites that I put AdSense on are getting into Google's index faster than sites that don't have ads. Is the googlebot that hits your site to optimize the ad content the same bot that puts you into the main index? Thx.
Not really, but in order to save bandwidth google has adopted the use of a crawl caching proxy that might explain what you are seeing. You can read about it here
Another fast way to get indexed if you have the Google Search tool bar installed in your browser is just type in your own URL and search for it. If it's not found, it will get indexed usually within 72 hours. Most new pages I add to my site get indexed within that time frame and usually less www dot wm8c dot com
Yea its just an marketing thing.. I think the most money they get is not from adsense but from making sales.
If you already have some incoming links, you can probably speed the process slightly for the rest of your pages by adding a google sitemap. For a Google listing of 3rd party tools, check http://code.google.com/sm_thirdparty.html
Really? I'm surprised if that's true. Loads of people have got that installed but I've never heard that....
