Search Engines


1b. The first page to appear in Google for searching 'electric cars' was Wikipedia, in which the words 'electric car' appeared 136 times throughout the whole article. This page, used 182 references to collect all the information. Google is the reason why most people visit Wikipedia. The co-founder of Google, Sergey Brin, believes that Wikipedia is “one of the greatest triumphs of the Internet” and “an invaluable resource to anyone who is online”. Google loves Wikipedia, there are 99% chances that, if Wikipedia has an article based on query, it will be shown on the first page. http://www.pagetrafficbuzz.com/wikipedia-appears-page-google-searches/13269/
The second page that appeared was Telsa Motors (http://www.teslamotors.com/) which was founded in 2003 and they wanted to prove that electric cars could be excellent also. In this page you can see the different models Telsa Motors offers.
The third page to appear was Electric Cars, (http://electriccars.com/previews/main.cfm?FUNC=MAIN) which has as a mission not to produce gas or pollution. They also have a ranking of the top 10 electric cars. Also, they show the worldwide dealer network.
The fourth page that appeared was Hybrid Cars (http://www.hybridcars.com/electric-car) that explains what an electric car is, and then compares electric vs. Gasoline, also they have a list of the new upcoming electric cars. It also provides a lot of information about electric cars and its benefits.
The second search engine we used to look for ‘electric cars’ was yebol. I consider that the first link (http://www.thedailybeast.com/newsweek/2009/01/09/switched-on-highways.html) was ranked in that position because of the amount of times that the word ‘electric ’ and ‘cars’ appear throughout the article. In addition, yebol may recognize how popular this webpage is.
The link ranked second on Yebol’s search engine was http://www.milesev.com/ This may be because of the fact that this webpage that sells electric cars and tries to promote them. The webpage called milesev refers to miles electric vehicles. This search engine takes into account the use of the word vehicle, a synonym for cars.
Thirdly ranked appears http://www.teslamotors.com/ Tesla is a webpage about cars specifies on ‘electric cars’, when you click on an interactive button. This suggests that the search engine used, has a deep investigation on the websites so it also bases it results on the links you may open within the webpage.
In the fourth ranked link, the word ‘car’ appears in the title, in the name of the webpage, and throughout the article. This webpage is a guide on cars and prices, and a listed category is ‘electric cars’ http://www.thecarconnection.com/
Besides, in every webpage ranked in the first four places, our search query appeared as one or more of the webpage’s tags.
c. The search engines algorithms are based on the coincidence of your query with the webpage tags and also with the amount of times your query or part of it is mentioned throughout the text. It also analyzes the importance of your query in the webpage such as if your query is described and deeply analyzed or just being mentioned. In the case of google, Wikipedia appears as the first ranked link in several cases not only because of your query and its popularity but also because Wikipedia is highly supported by Google.
2. Search Engine Optimization is a process where the search engines are optimized for the people who enter, it makes it more "friendly". The most important objective is the choosing sites from the words that the user imputs in the search engine. When a page is more visited that the others, it tends to be in the top of the page when you look for something. Thats part of the process of SEO. Also, the SEO targets to optimized other type of categories, such as images, videos or news.

There are a lot of startegies to make your webpage appear at the top of Google. One of the most important techniques is the title he tag. The page title is the first thing the search engine will look for. It is essential to put one or two keyword and not spamming it. The second most important technique is the meta tag. Is important beacuse it appears listed in te search results. It is what the user reads when i comes up and makes them decide to click your web page or not. As title tag, it is important to us keywords but not to many. The third most important is the proper use heading tags. This helps the search engines, users and web browsers to know where the major key points of your copy are. http://freelancefolder.com/10-top-seo-techniques/
3. When we searched Miserable failure on Google, we found that many links were related to the ex-president of United States, George Bush, before when people searched “miserable failure” the first link that appeared was his biography, although the 2 words never appeared in the article. But that happened because Google doesn’t search only about the content of the page but also about other links the page has. This is called Google Bombing, when you relate one phrase to certain articles which maybe have nothing to do, but they appear when searched.
When we searched Talentless hack, we found that most pages talked about Google bombing, then we found an article that explained that Adam Mathes who has a weblog and an online journal of his thoughts and investigations, used a bomb to make his friend page appear when talentless hack was searched on Google. This may be used by businesses or corporations to improve their position in search results.
