The Technology Behind Google Rankings

The Google Blog posted their third entry on how Google rankings work. This write up is more about the technology behind their ranking system. I’ll bullet point some of the key points for you all:

• Google has technologies in crawling and indexing pages.
• They try to associate concepts to pages, even if those concepts aren’t clear from the language on the page.
• Google makes a distinction between “important and less important words in the page.”
• Google also looks at the “freshness of the information on the page.”
• Google has a spelling suggestion system
• They also have an advanced synonyms system
• And also a strong concept analysis system.
• Google uses localization systems (geo-location)
• Also advanced personalization technology
• They also take pride in their Universal Search technology.
• Finally, Google talked about their translation system named Cross Language Information Retrieval (CLIR). Google said, “CLIR allows users to first discover information that is not in their language, and then using Google’s translation technology, we make this information accessible.”

In addition, Matt Cutts of Google is making a last call to submit a request for what the Google spam team should work on next, so go ahead and make that submission.
