Difference between Google, Msn, and Yahoo
When you are in hurry, which search engine do you choose in order to get the best result? Maybe you just use the one that is familiar to you. Google, Yahoo, and Msn are the three most common search engines that we use in daily life. Although Yahoo and Msn are not the top five of search engines (based on Searchengineswatch.com Feb 2003), we still use those because we are used to using those sites. In my personal experience, I also never realized why I use those search engines. I just use them because the first time I use I was told to use “google.com” by my friend and it has become my habit. In this paper particularly, I will discuss how search engines work, and the similarities and differences of those three search engines. I hope based on the information I give, you will choose the right search engines in order to maximize your result and minimize your time.
First of all, I will talk about search engines. In general, there are three types of search engines. The first one is a crawler-based search engine. This term “crawler” is an acronym from “crawl” and “spider”. This system works like a spider that crawls through the sites, selects one, chooses one, and displays it. In other words, this search engine hires a special robot called a spider. It builds a list of words and notes which the spider finds, builds an index based on its own system of weighting, encodes the data to save space, and stores data for the user to access. Google uses this system. The next system is the human-powered directories implemented by Yahoo. This system has an open directory and subdirectory. This system is controlled by the user. The user must provide the website information including a right title and description or the result will be different than the user thought. The last system is only the combination of the first and second systems. Using this system, the first priority is based on its own database, and the second priority is based on the human-powered directories. Msn uses this technology.
Those types make up the main difference between Google, Yahoo, and Msn. In my experience when I type “used cheap car Ames”, the most satisfying result is the one from Google because it provides the information about used cars. Yahoo doesn’t give the result that I want, and Msn gives the information but some of it is not related to what I desire. On the other hand, when I type “pool”, Yahoo gives the most accurate things; it provides a tutorial on how to play a pool, where I can reserve a swimming pool, and also give information on sanitation pools. Google gives the most unrelated sites, such as it gives the magazine, and types of words; and the Msn results are between those two sites. It means Yahoo does better in a specific word search or Yahoo need a better choice of words in searching while Google does better in any kind of explanation’s word. And if you are not sure about the explanation, you can use Msn.
