THE SEARCH ENGINES:
A very simple definition of what search engine are, would be to say that it is the Internet’s version of a telephone yellow-page directory.
Looking for something on the Net but don’t know where to find it? – just go to one of the search engines, type in the appropriate word or phrase (in theory, similar to paging through the phone book), hit “enter,” and voila! You are given a list (a very, very LONG list!) of websites that are (supposedly!) relevant to your needs.
Now the superficial wisdom is that search engines offer us Internet Marketers an unlimited amount of FREE traffic.
The hype tells us that “all” we have to do is achieve a high placing on a number of the important search engines and we’ll never have to worry about paying for advertising again.
Search engines were designed as RESEARCH tools, NOT as ADVERTISING tools.
Search engines were designed to do as follow:s to do as follow:
Crawling entire WWW
Building Index based on results from crawling
Ranking and serving results
Now, Imagine the World Wide Web as a huge underground network of stops in humongous virtual city.
Each station is a unique document and the search engines need a way to crawl the entire network and find all the stops along the way.
Therefore, they use the best possible way – links.
Once search engines find all the pages they draw essential info from them and store selected bits of information in the database ready to be recalled when needed. In order to accomplish the enormous task of holding billions of pages’ information that can be accessed in a fraction of a second, the search engines have constructed massive data centres all over the world.
When someone performs an online search it requires the search engine to search their database of billions of documents to do two important tasks:
- Return only those results that are relevant or useful to searchers query
- Rank those results in order of perceived value or importance.
Search engine indexing:
Collects parse, and stores data to facilitate fast and accurate information retrieval. Index design incorporates interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics, and computer science.
This day’s hundreds of factors influence relevance.
At present, major search engines interpret popularity as importance – meaning, more popular website, page, or document then surely more valuable the information contained there must be.
This assumption has proven fairly successful in practice as the search engines have continued to increase user’s satisfaction by using metrics that interpret popularity.
Popularity and relevance factors are filtered by algorithms that sort out valuable info from the ones that provide less of the quality.
The algorithms are comprised of hundreds of components – “ranking factors” directly responsible for website SERP position.
However, are the Search Engines “JUST” in their actions and verification process???
Search Engine Optimization in a simple word would be a process of transforming web page built by humans into web page easily consumable for both – other humans and for Search Engine robots.
