Google recently filed a US patent which reveals a great deal of how they rank your web site. Key surprises include:
- The age of the registered domain is considered.
-The days of Spamming Google are drawing to a close. With this patent they reveal just how hard they're coming down on Spam sites.
- Google relies heavily on inbound relevant links to rank a site.. As well as the number, quality and anchor text factors of a link. Google seems to also consider historical factors. Apparently the Google 'sandbox' or aging delay begins count down the minute links to a new site are discovered. Google records the discovery of a link, link changes over time, the speed at which a site gains links and the link life span.
- The anchor text link should vary but remain consistent within the site content. No more using your main keywords on every link exchange you gain. That's 'anchor Spam'. Instead vary them around your top five to ten keywords.
-Unethical link exchange can result in a ban - host and IP may also be recorded.
- Click through rates may now be monitored through cache, temporary files, bookmarks and favorites via the Google toolbar or desktop tools. CTR is monitored to see if fresh or stale content is preferred for a search result. CTR is also analyzed for increases or decreases relating to trends or seasons.
- Web page rankings are recorded and monitored for changes. The traffic to a web page is recorded and monitored over time.
- Sites can be ranked seasonally. A ski site may rank higher in the winter than in the summer. Google can monitor and rank pages by recording CTR changes by season. • Bookmarks and favorites could be monitored for changes, deletions or additions. • User behavior in general could be monitored.
- The frequency and amount of page updates is monitored and recorded as is the number of pages. A stale page that receives good traffic may hold it's own and not require an update. So don't update for the sake of it.
- Changes in keyword density is monitored and recorded as are changes to anchor text.
- The domain name owner’s address is considered, most likely to help in a local search result.
- The technical and admin contact details are checked for consistency. These are often falsified for Spam domains.Read the complete article here
