SEARCH ENGINE OPTIMIZATION | Part One
Searching Process
Searching the document at one particular site can so easily but at the same time feel so hard, considering there are so much information spread everywhere, even California University mention in this time there are more than 50 billion WebPages in internet even there are no one who really know exactly how much number is.
The possibility problems could happened is there are no data about the WWW content in the standardization form. Not like catalog in the library, that has standardization worldly according to the book title, though in large number.
In the web searching, you always estimate what kind of word there on page which you wish to find. Or may be what subject was selected by someone to manage the webpage which they have, what kind of topic were they wrote.
If you do what was recognized with searching on webpage, you don’t search in fact, impossible to search directly in WWW.
Web is consisting of a lot of page which is kept from various servers in all over the world. Your computer is not directly search to all computers.
What you can do only through computer, accessing one or more agent called search engine in this time. You are searching to database which they have. The database collect sites which they find and they save it.
This search engine agent provides the result in the hypertext form link with URL go to the other page. When you click this link and go to the document address, image, sound, and many other form on the server is reserved to you according to the information in it, this service can reach all over the world.
So this is impossible for someone to search to the entire computer which is linked on internet, or even search engine claim that they do it.
Search Tools Categories
In this time, we find at least three search tools form, you use different strategy to exploit potential ability from each, that is:
Search Engine and Meta Search Engine
Characteristic:
- Saves the chosen page data in full text form;
- Search based on keyword, they try to reconcile with precisely the keyword with the text in document page;
- Not necessarily to browse, and there no subject from category;
- Database collected by spider, that is computer that have the robot program, has ability which is impossible from human touch or view;
- Search engine measure: from small scale till can saves plenty of WebPages (around 20 billion WebPages);
- Meta search engine swiftly do searching into some databases from various search engine in one request. Result of it? Is list from many search result in some search engine which is involved.
I often use search engine like Google, Yahoo Search, Ask and meta search engine like Dogpile, Copernic, and other.
Subject Directories
Characteristic:
- Site which have been listed comes from direct selection which done by human, once in a while experts to selected subject;
- Information which they have is often carefully evaluated, but it’s not always and sometimes not, especially for they who have plenty of data;
- Usually managed in subject form and hierarchy structured directory;
- Provided with the description note (not to Yahoo);
- The subject and category can be browsed or search in selected words;
- No-Full text of document, searching asked for more specific compared to searching through search engine, because keyword is not compared to content of site page, but only at the subject, category and Description;
- There are thousands or even more directory subject in reality and anything you need can get there.
The directory suggested by me are dmoz, librarian index, infomine, about, etc.
Specialized Database (Invisible Web)
Characteristic:
- It is the web that provides access facility through searching box into database content to any computer;
- Could be in various topic, could only be simple matter, specific work, governance, etc;
- Consist of many pages give searching result from online directory catalog.
Location of special database to look for from the data can be pledged through the directory like dmoz, Yahoo Directory, etc. Data is kept in the directory which used to guide in searching of webpage considering selected keyword which used by common search engine.
