Learning SEO: Search Engine Basics

What is SEO, bit by bit we have started to understand it. We've been a little acquainted with SEO through previous articles. From the article we also know that the activity was good SEO on-page SEO and off-page SEO is actually can be done by anyone. The next step what else? On Learning SEO flashbacks this time we had to learn about the History and Basic Search Engine Search Engine to find out How does it work? What is its function? Where did it come from? Who is the manufacturer? Why do search engines exist? and so forth. 





History Engine search algorithm In the early days of the introduction of the internet, then search engine does not exist. Even in those days, the internet is not as easy, sophisticated, and as comfortable as it is today. Internet was nothing more than a collection of sites FTP (File Transfer Protocol). At that time, the Internet is nothing more than just a place to download or upload files.
Since that time the search engines do not exist, then when a user wants to find a file on the internet, he must find his own. That is by accessing the site, then browse any folders that exist on the site, then see if the site is in need it to save the file.
If you find that the file is not found in sites that were visited, meaning he must look at other sites, and browse any folders that exist on these other sites. And so on, until he managed to find the files he sought.
Well ... do not you imagine? How tiring, and can make people so frustrated. Only to find just one file, a user must be willing to spend time and energy so much. All the obstacles and difficulties, finally making a student from McGill University in Montreal finally decided to look for an easier way.
And finally, in 1990, Alan Emtage the student's name, managed to make a first search tool that can be used on the internet.Homemade tool that works by collecting, and then index the name of each file is on a site. Index data is then stored into a database.
Thanks to its tool is then, when a user wants to know whether the file was looking for is in the site being visited, the user no longer need to find a way through every folder or read any existing file name. He's pretty to look inside the database that was created by Alan Emtage earlier. Simply by typing a file name to search, then the user will know whether the file is found, or not.
Well ... imagine no, what a help tool created by Alan Emtage this.This tool is named Archie. Is Archie is just like search engines that exist today? No, Archie was still far from what we now know as the search engines.
In 1991 Mark McCahill from the University of Minnesota revealed his thinking, he said ... if we can find a file on the Internet, means that we can certainly look for specific text on the internet. In his thinking, we can do it in a way to index text-specific text, and save an original file for reference.
Since that time there has been no program that can do that, then Mark McCahill and then create your own. He named the Gopher program, which indexes all text files on the Internet, which later became the first website which can be freely accessed on the internet. We make this Gopher, other programs were needed.
This program is needed to find the file referenced by the index created by Gopher. Created Veronica (Very Easy Rodent-Oriented Net-wide Index to Computerized Archives) and Jughead (Jonzy's Universal Gopher Hierarchy Excavation and Display). Two of the program is created with the purpose to seek and find the file referenced by the index are made Gopher.
Veronica and Jughead work the same way, ie create a user could search for information contained in the index based on keywords or keyword. Of course this is the origin of these two search engines that we know today. Of course after going through various process development and improvement
In 1993, finally the real search engine that was first established, the search engines with a shape like a search engine that we know today. Search engine was developed by Matthew Gray, and given the name Wandex. Wandex is the first program that succeeded in doing two tasks at once, the index and also do a search into the index.
This technology is the first program to crawling, or reaching the Internet. And finally it was the base technology used to create web-crawling programs today. And since then, various search engine technologies were developed by each search engine.
Beginning in 1993 until 1998, several major search engines that we know today began to emerge, namely that:
Excite - 1993 Yahoo! - 1994 Web Crawler - 1994 Lycos - 1994 Infoseek - 1995 AltaVista - 1995 Inktomi - 1996 Ask Jeeves - 1997 Google - 1997 MSN Search - 1998 Well ... that was a history of their origins search engines. Currently, search engines are increasingly sophisticated. Search engines have become an inseparable part of the Internet world. Not surprising really, because search engines give a lot of convenience for Internet users.
With search engines, we can find documents or anything else that we want to find on the internet. Kaga have thought so, until now the search engines already more or less 17 years old.
What Is a Search Engine? There are two teams working on search engines. One team worked on the back, and one team worked on the front. Now we discuss the team that worked on the back first.
The team that was in the back, in charge of collecting information about an existing page on the internet, or commonly referred to the web page. The information collected is:
Keyword or keyword. Phrase or sentence. URL of the page in question. Links from other pages that point to that page (link-in). Links from the page that leads to another page (link-out). Keyword or keyword information is needed to determine whether in fact the main topic of a web page. So also other information, we will discuss later what's the point.
The team in question here is not really a person or group of persons. But in the form of software or software or referred by a computer program. The team was given the name Crawler, or spider, or robot. This team will keep all information it has collected into a database. Up here, it means that the task team finished ntu.
Now we discuss teams or programs that work on the front. The team that worked on the front is in the service user or people who want to use the services of search engines. This team complements him with a device that they need to communicate with the user earlier. This device is called the interface or interfaces.
Interface or the interface that is what appears before us as we visit the search engines. A box to enter or typed word / sentence, and a button to execute. Boxes and buttons that is what is meant by interface or interfaces. Through this interface, we as users can communicate with the software used by search engines earlier.
When a user entering a word / phrase into the box, then click the search button, that's when teams are at the front before starting work. This team will start looking for the word / phrase that we entered earlier. The team that is on the front of this, will look for the word / phrase into a database that was created by a team that was in the back earlier. This database is usually already been prepared, sorted by certain criteria.
Until the team front, the search word / phrase, will quickly find the word / phrase that we seek. After the front of the team is looking for the word / phrase that we want, so then the team will report the results to us.
if it turns out the word / sentence is in the database, then the team will display a page that contains a variety of web pages containing the word / phrase that we seek. This page is called the SERP, stands for Search Engine Result Page.
