The filing unquestionable provides SEO’s with valuable insight into Google’s tightly guarded search intelligence and confirms that Google’s information retrieval is based on historical Google Snake data.

What exactly do these changes mean to you?

Your credibility and reputation on-line are going under the Googlescope! Google has defined their patent abstract as Google Snake Game follows:

A system identifies a document and obtains one or more types of history data associated with the document. The system may generate a score for the document based, at least in part, on the one or more types of history data.

Google’s patent specification reveals a significant amount of information both old and new about the possible ways Google can (and likely does) use your web page updates to determine the ranking of your site in the SERPs.

Unfortunately, the patent filing does not prioritize or conclusively confirm any specific method one way or the other.

Here’s how Google scores your web pages.

In addition to evaluating and scoring web page content, the ranking of web pages are admittedly still influenced by the frequency of page or site updates. What’s new and interesting is what Google takes into account in determining the freshness of a web page.

For example, if a stale page continues to procure incoming links, it will still be considered fresh, even if the page header (Last-Modified: tells when the file was most recently modified) hasn’t changed and the content is not updated or ‘stale’.

According to their patent filing Google records and scores the following web page changes to determine freshness.

  • The frequency of all web page changes
  • The actual amount of the change itself… whether it is a substantial change redundant or superfluous
  • Changes in keyword distribution or density
  • The actual number of new web pages that link to a web page
  • The change or update of anchor text (the text that is used to link to a web page)
  • The numbers of new links to low trust web sites (for example, a domain may be considered low trust for having too many affiliate links on one web page).

Although there is no specific number of links indicated in the patent it might be advisable to limit affiliate links on new web pages. Caution should also be used in linking to pages with multiple affiliate links.

Developing your web page augments for page freshness.

Now I’m not suggesting that it’s always beneficial or advisable to change the content of your web pages regularly, but it is very important to keep your pages fresh regularly and that may not necessarily mean a content change.

Google states that decayed or stale results might be desirable for information that doesn’t necessarily need updating, while fresh content is good for results that require it.

How do you unravel that statement and differentiate between the two types of content?
