Whats the difference betwee:

Googlebot downloading your sitemap

and

Home page crawl: Googlebot last successfully accessed your home page on Apr 29, 2007.

Thanks.

One is a listing of all your pages and the other is a single page.

so a googlebot will crawl daily to get my sitemap but once in a while to crawl for content....??

No, they use the site map as a road map of links to be crawled at whatever rate they crawl your site. They will at their own pace crawl the links in your site map. This is where good PR can help your site as Google will increase the rate and depth of it's crawls as your PR increases.

The homepage is simply the obvious front page and entry way of your site. They cache the top page every so often to note changes and updated content.

cool...thanks, where can i find good tip on increasing my page rank...i know of 1 way which is to buy link space on a site with a good page rank....what are other options?
