google chaches it own domain after every few days after every 3-4 days but caches my websites homepage every day. Strange!!!!!!!!! http://webcache.googleusercontent.com/search?sourceid=chrome&ie=UTF-8&q=cache:www.google.com
Hmm...I see no logic behind this and no wonder if they would want to cache their own pages for not that frequent, but your website is a different case. Is your website update regularly? like daily. If you have a regular update pattern then Googlebots would come to crawl and cache your website in a same pattern as well.
Pretty nice that Google is crawling your site on a daily basis. What sort of content do you have on the site?
that's right, i agree with Sxperm.. besides are you not happy with that.. it only means one thing, your site google friendly..
Well, that scenario didn't mean you got better site than Google. All you can do it to take advantage of daily caching of your site, make more contents for Google to index so you got bigger possibilities to rank on many terms.
