Introduction - What Is SEO

When you enter a query in a very internet search engine and hit 'enter' you have a listing of web results that includes that question term. Users normally usually visit websites that are towards the top of this list as they perceive the crooks to become more relevant to the query. If you have ever wondered why many of these websites rank much better than the mediocre ones then you certainly have to know that it's caused by a powerful internet marketing technique called Search engine marketing (SEO) que es SEO.

SEO is really a technique which helps engines like google find and rank your site more than the millions of other sites responding to some search query. SEO thus can help you get traffic from search engines.

1. How Search engines like google Work

The very first basic truth you need to know to understand SEO is that engines like google are not humans. Even if this may be obvious for all, the differences between how humans and look engines view webpages aren't. Unlike humans, engines like google are text-driven. Although technology advances rapidly, search engines like google are faraway from intelligent creatures that can feel the attractiveness of an awesome design or benefit from the sounds and movement in movies. Instead, search engines like yahoo crawl the Web, investigating particular site items (mainly text) to have an idea what a site is about. This brief explanation isn't the most precise because as we will have next, engines like google perform several activities so that you can deliver search engine results - crawling, indexing, processing, calculating relevancy, and retrieving.

First, search engines like google crawl the internet to view what's there. An expert is conducted with a software program, known as a crawler or perhaps a spider (or Googlebot, as is also true with Google). Spiders follow links derived from one of page to a different and index everything they find on their way. Having in your mind the amount of pages on the Web (over 20 billion), it is impossible for a spider to check out a site daily simply to find out if a brand new page has appeared or maybe an existing page has been modified, sometimes crawlers may well not wind up visiting your website for the month or two SEOMetrico.

What you can do would be to check such a crawler sees from a site. As mentioned above, crawlers are not humans and they tend not to see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have a lot of these on your own site, you'd better run the Spider Simulator below to determine if these goodies are viewable through the spider. Should they be not viewable, they will not be spidered, not indexed, not processed, etc. - in a word are going to non-existent for search engines like yahoo.
