Below we've included a screenshot of the crawl stats for Nelso.com, taken from the webmaster interface at Google. As you can see, the page load times for Nelso.com have improved steadily over the last 90 days, and now average a little under 700 milliseconds.
It's also obvious from the graphs that page load time has a direct effect on how many pages the GoogleBot crawls per day (and thus how many pages from Nelso.com end up in the Google index). That leads to a question, and maybe a reader can comment on this post with the answer. Is 684 milliseconds a good page load time, or just average? What do other large sites see in their GoogleBot crawl stats? Will the relationship between GoogleBot crawl speed and page load time hold true if we decrease page load time another 50% (i.e. will the GoogleBot double the number of pages it crawls per day on Nelso.com)?
OK, maybe that's three questions. But you get the idea.
