Google’s Ranking System
An article by Sandi Baker
Google is the number one search engine. Are you aware of the technology aspect behind its ranking system? Fully understanding all of their principles is important to understand the ranking system. The nucleus of their technology involving their methodology is devised for the field of Information Retrieval. This system is a foundation of mathematics, library science, information science, cognitive psychology, information architecture, linguistics, statistics, and physics.
How this retrieval system works is by the searcher requesting the information. The data requested is provided through a software agent that actually pushes that requested information. The retrieval system may use a full test logical view but in most cases reduces it with a set of keywords. This is done with a process of exclusion of stop words, and the use of stemming, and by identifying noun groups.
Note that when this retrieval database is set up, it works in this manner:
The documents are ranked by relevance
Then by useful information
Then by a subset seen as of interest
This system is basically for ease of retrieving information and not being overloaded by it. This gives Google their groundwork for the formula which they have built on top of, link structure and numerous other innovations.
There are three components of the search process:
1. The first being the crawling and indexing of the pages but there are other important aspects.
As a website owner I can tell you that the key to proper placement is directly related to your meta keywords and phrases that are inserted correctly.
Another component is to understand a users search and the important concepts of their particular search even though they many not be obvious. In other words if you were looking for something specific with a place. The search result would pull up the homepage of that site even though the name was not mentioned in the title page.
Google makes other distinctions regarding wording and your updated information. When it comes to this phase I have found this very helpful as I add new articles. Topics that I write about are listed and when the searcher pulls up the article they can then directly link to my website. Writing articles and adding new information is an important step. When you do your setting most website owners, including me, that their content is refreshes on a weekly basis. I add new articles to my website as well as to directories for optimum rankings.
2. Best in-class spelling suggestion system asks if you meant a certain spelling to clarify what you are looking for.
Advanced synonyms system- The synonyms of the queries is related to where a user asks for an item such as dresses for a wedding, and automatically the results are wedding gowns. Synonyms are an excellent way for a user to find your information as in the case of my website. Such as they may be looking for software for free and the results would pull up free software. When you do your Meta keywords make sure that they are broad enough to be pulled up in this manner. Very strong concept analysis system-The algorithms understand what the user is looking for to return the results that they are looking for. There is differentiation in place and particulars in the search.
3. Google understands its users and localities.
The results that a user is looking for is on “best locally relevant results served globally”(1). Another feature is for those that have Google accounts and are actually logged into them while searching. While doing a query they “tailor” the results to the user. Finally there is the Cross Language Information Retrieval technology. This translates language of another into English.
While word frequency and page structure always comes into play we may not think about all of the technology behind how the entire process works. It is important to understand this and Google’s philosophies.
