There are two ‘cache’ term that you might encounter in Google. The first one is the ‘cache’ link that you can find underneath the search result in Google. Check out the photo from Google Guide:

The other one is the one wherein you type in the ‘cache’ word in the google search bar to find out which copy of the page Google has in his storage bin, its latest cache of your site:

cache:www.domain.com

The resulting page shows something like this.. take from Tube-Master February 12, 2010.

It says here that the page has a cache date of February 11, 2010 which is a good thing since it’s just a day old.

By using the cache operator of Googel, you’ll know if the search engine is frequently indexing your website or if their robots and spiders are crawling your sites.

Another cool thing that the cache operator shows us is the Text Only Version link. Clicking this like will display the cache page without any style. What does it do? Well, it basically shows you how Googel sees your site. You can then know if you have a perfectly optimized website (onpage). By viewing the page naked, or bare boned, you can see if the h1 and h2 are set up properly or that if the page is read left to write.. you can see if the spider crawls the content first before the sidebar and adjust accordingly.

Hope the information helped someone!

cheers!
