Welcome to WebmasterWorld Guest from 188.8.131.52
The patent tells us explicitly what features it was looking for in a site that might seem to indicate that the site was a quality site.
This patent is about a search system that includes a site scoring engine that generates site quality scores for sites.
How Google May Calculate Site Quality Scores (from Navneet Panda) [seobythesea.com]
So, the patent seems to place a lot of value on queries that somehow mention and refer to the site when they ask for information.
One site label identifying a particular site can be specified using an operator, e.g., a “site:” operator, followed by a name, e.g., a domain name, for the particular site.
...wherein a query is associated with the particular site when the query is followed by a user selection of a search result that (a) was presented, by the search engine, in response to the query...
That explains all these ads posted in 3rd world countries asking users (and often giving them proxy server access) to enter marketed domain and some search term and visit the site.. it is prone to spam.
Interesting. I assume that this would benefit well known (ie 'brand') sites and EMDs.
- using "site:" operator with the query
- typing the query and adding the name of the site,
- navigational queries to the site
and so on.
