How search engines work, google, yahoo ect.

June 2, 2008 · Filed Under Internet, Search Engine Optimization

Google has a bunch of servers in Data centre’s. Data centers are basically a cluster of computers/servers in a single location on a network.

Google sends out what they call Spiders. They go out on the internet and “crawls” the internet. Goes from one website to another following links and indexes the webpages. The spiders read the page and index them on the google server. Store’s some information about the url, what the website is about ect. Google can then determine what the website is about after a number of words or phrases are repeated. So a blog about the internet will have the word Internet repeated quite alot of times. Therefore, google “sees” that about and automatically gets told that its about the internet. Then your website has been Indexed. The same goes for any other page.

When you then type in “the internet” in google, it will quickly have a look at the logs on their server and find all the data that matches your search. Then, display it in a list in your browser. The websites aren’t actually stored on the google servers, but a database to what everything is about and where it can be found.

As you can expect, its quite a large database/list.

When it comes to being “found” on google there are multiple things you are going to have to do. Think of it as a race. If you have your new website up, and nobody really knows about it, google probably will also not know. It takes a couple of days maybe even weeks for your website to be indexed in Google. That is where Search engine optimization comes in. using the correct amount of keywords and writing your content in the right way.

It takes quite a while for you to get the right balance of keywords and content. Writing in a non-spam like way. Stay away from repeating the same keywords more than about 3 times in a sentence.

There is alot more to Search engine optimization than just using the right words.
More on that later.
