To see Google’s cache of your webpage, you can either run one of the SEO toolbars in your browser, or you can follow Googles instructions, which are simply:

Copy & paste the following in the address bar directly in front of your URL

http://webcache.googleusercontent.com/search?q=cache:

Frankly, that’s all this tool does.

Just paste your URL in this box, and you’ll be taken to Google’s cache of your page, with the date showing at the top.

Also take a look at the text version – what Googlebot actually sees when they crawl your site.

 
If you get a page showing Google search results, that means your page isn’t cached.
