Google cache

How important for SEO is being cached?

[hmk61]

Someone interested in a link exchange with me says he only wants to be linked from a page of mine which is cached by Google. I checked and my index page on my main site, which has been up for over 2 years and has remained unchanged for the past 2 months is not cached.

Is being cached by Google important? If so, why and is there anything one can do to get cached? Thanks.

When there is a cache link, it indicates two things: firstly, that the page has been indexed, and secondly the cache gives a snapshot of what the page looked like to Googlebot. This means that the link buyer can check to see whether you have cloaked the page, for example to add a nofollow on the outbound links.
