That was kind of a clever move by GoDaddy.
We don't know if what is in the patent application is what Google has been doing, or even if it is what they will be doing. But, it can give us some sense of what they've considered.
Jill's analysis is pretty spot on concerning good practices, but the patent application is probably worth attempting to struggle through if you have a web site, or work on the web and care about how sites show up in the rankings.
There's nothing groundshaking or earth breaking in the application, no incredible new technology unveiled, no real secrets on how to rank well in the search engines.
But if you read it carefully, it comes across as if a number of smart folks, who know a lot about search engines and search results, got together, and brainstormed on ways to try to make search results more relevant, and eliminate some spam.
A followup patent application,
Systems and methods for determining document freshness, from last week, adds a little more to the topic, and refers to the historical data patent that is the subject of this thread.
Another one,
Methods and systems for personalized network searching, may explain how Google might get access to some of the information in the Historical Data patent application described in the section on "User Maintained/Generated Data."
Some speculation there on my part. Again, not really earth breaking changes, if they are something that Google may adopt. Keep in mind that just because it's written in a patent application, doesn't mean that the search engine is using it, or will be.
But it can be interesting to see if Google does start using some of the ideas involved.
