Blog bLoG na naman!
aruy! technical naman yung sakin ;)
Sa mga pips jan na nag wa-Wonder, paano nga ba gumagana/ nagwo-work ang mga search engines like Yahoo?
Ganito po kasi yan. . .
Search engines like Yahoo use SEOs(Search Engine Optimization) or Meta tags to locate "old" and "new" websites. SEOs are words and phrases that appear on a web page or website that are indexed by search engines in a way that best describes it. Savvy bloggers often use key SEO phrases in the title of their blog and throughout it to help search engines better categorize their subject and blog. Meta tags are words added into a special section of a web page or website by the designer to describe it. Meta tags are not visible to an Internet surfer, but are visible to a crawler.
After a crawler finds a website or web page, it is indexed into the search engine system under a category or categories. So a web page with the title "Toys for Puppies" would most likely be listed under the categories "toys" and "puppies." The crawler would decide to do this based on the terms in the title. Then, when a person surfing the Net for information lists the words "toys" and "puppies" in the search engine box, this page would pop up in the results.
There are times when a website or web page that appears to have nothing to do with a specific search pops up in the results screen. This usually happens when the SEOs or Meta tags are not in line with the subject matter. Also, there are times when a web page or website is missed. However, the designers of search engines have remedied this problem by adding areas on their own specific pages to allow users to submit their web page or website to them. Basically, the makers of the search engines want to be sure that they are able to serve anyone who comes to them by providing the most accurate information available on the World Wide Web.
Methods for Search Engine Optimization
There are several ways that websites can create search engine optimized content. Search engines are run by series of algorithms that will determine the relevance of web search terms to web content. In the industry, there are two terms that are used for SEO, "white-hat" and "black-hat" search engine optimization. White-hat optimization refers to web content that follows search engine guidelines and does not use deceit to trick the search engine. On the other hand, black-hat refers to techniques that deliberately attempt to trick the search engine. For example, one technique that some sites use is to include keywords in a text color that is the same as the background color of the page. That way, the user cannot read the text, but the site will be loaded with keywords that will make the search engine think that the page has relevant content when it may not. Most search engines, however, will ban sites from their search engine if they find out that deceptive tactics are being used.
The Bottom Line on Search Engine Optimization
Though this idea is debated among Internet gurus, the most effective way to improve search engine optimization is to simply create good content. The reason for this is that well-written and structured content will attract more traffic simply because the content will actually be relevant. Over the long run, then, good content will always outlast sites using black-hat methods and will eventually become recognized as relevant by a search engine.
Yahoo! Search Technology (YST) works night and day scouring billions of documents on the Internet to give you the most comprehensive, up to date, and relevant search experience.
