How Search Engine Work - SEO Learning

Posted by Unknown on Senin, 13 Juni 2011

Hello World, Today i want to talk about how search engine work .One thing we must be clear that you need to know about SEO is that search engines are not humans. While this may be obvious to all, the differences between how humans and search engines view web pages are not the same.
Unlike humans, search engines are text-driven. Although technology advances rapidly, search engines are far from intelligent creatures that can feel the beauty of a cool design or enjoy the sounds and movement in cinema.

Instead, search engines crawl the Web looking for items of a given site (mainly text) to get an idea of ​​what subject it is the site.

This brief explanation is more accurate because, as we shall see, search engines perform several activities in order to provide search results - indexing, processing, calculating relevancy.

First, search engines crawl the Web to see what's there. This task is performed by piece, called a crawler "crawler" or a spider (or Googlebot, as is the case of Google). Spiders follow links from one page to another level by doing everything in their path.

Taking into account the number of web pages (more than 20 billion), it is impossible for a crawler to visit only one site per day just to see if a new page has appeared or if an existing page has been modified.

Sometimes, crawlers do not visit your site for a month or two, so during this time your SEO efforts will not be rewarded. But there's nothing you can do about it, but to leave quietly. What you can do is check what the tracker sees in your site. As already mentioned, crawlers are not humans and they do not see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have tons of these on your site, you better run and simulate how a site's feed information for the search engines properly.

If this information is not visible, they will not be spidered, not indexed, not processed, etc. - in a word that will be absent for the search engines. I hope this article, which is about " How search engines work ?" can be useful for you
