A lot of people in business go by the old saying “First impressions are everything”, however, with Google and the other search engines this is completely opposite. With the search engines they base their results on the last time they crawled the web in order to provide the most up to date results to searchers. However, the search engines do not crawl equally, in fact they are very biased on who they crawl and when. In order to get crawled and indexed often you have to earn Google’s trust.
Today, search engines are looking for the latest and greatest to display in its SERPs. This means that classic link building techniques are going to be less effective than they have been in the past. Google is going to start looking for the best, most up to date content to display to its users so site age will come into effect but so will site trust. This keeps brand new start ups from dominating the first page, but also keeps stagnate, out of date sites from clogging up the works as well. This is where the Google cache comes in. The cache is a carbon copy of how your site looked the last time Google visited it, and it will tell you when that was exactly. Google, like any other company, does not like to waste time and resources so it crawls sites only when they need to.
If you have a static website the last crawl date is not that big of deal because you site is not any different now than it was then. If you have a blog or a blog on your main website, then this cache date should be very important to you because it tells you two things. First, it tells you what content Google has indexed for your site, and, second, it tells you how much Google trusts your site. You can figure out your trust rank with Google and other search engines based on how quickly they index and cache your site after publishing new content; the quicker they crawl your site, they better your trust ranking with that search engine. To improve this ranking all you have to do is publish quality, unique content. When you do this Google sees that every time they visit your site it has changed, and will, in a sense, bookmark it for quick indexing every time you publish something. Like everything with search engines (except maybe PPC), this will not happen overnight.
