Without a doubt, just because it is in the patent doesn’t mean it will ever be used. However it does give you an idea of thier thinking. To me it is more of a guide of things I might want to start looking out for, maybe do a little testing.

In many cases, changing to fit something mention in a patent is just a good idea anyway.

As an example, one thing in one of the latest applications is that Google might start looking at how long a domain is registered for. Even mentioning spam sites seldom register for more than a year.

I now register my sites for the maximum that I can, it does me no hark to do this, it’s cheap, and it might even provide some benefit with Google. LIkely a small benefit, but it adds up.

I think reading the patents provides some good guidelines to consider when doing SEO.
