Once you enter a query in the google search colliding with 'enter' you have a set of web results which contain that question term. Users normally usually visit websites which can be near the top of this list as they perceive those to be more strongly related the query. If you have ever wondered why some websites rank a lot better than others then you must know that it is caused by a powerful internet promotion technique called Seo (SEO) que es SEO.

SEO is a technique which assists search engines find and rank your site higher than the countless other sites in reaction to a search query. SEO thus makes it possible to get traffic from search engines like yahoo.

1. How Search engines like yahoo Work

The 1st basic truth you need to know to understand SEO is always that search engines are certainly not humans. Even if this could be obvious for everybody, the differences between how humans and look engines view website pages aren't. Unlike humans, search engines are text-driven. Although technology advances rapidly, search engines like google are not even close to intelligent creatures that can notice the attractiveness of a cool design or take pleasure in the sounds and movement in movies. Instead, search engines like google crawl the internet, investigating particular site items (mainly text) to obtain a thought that of a site is about. This brief explanation isn't the most precise because when we will have next, search engines like google perform several activities in order to deliver serp's - crawling, indexing, processing, calculating relevancy, and retrieving.

First, search engines crawl the internet to see precisely what is there. This is completed by the software program, known as a crawler or a spider (or Googlebot, as is also the truth with Google). Spiders follow links in one page to a new and index everything they find enroute. Having planned the volume of pages on the internet (over 20 billion), it really is impossible for a spider to visit a web site daily simply to see if a fresh page has appeared or if perhaps a pre-existing page has become modified, sometimes crawlers might not end up visiting your web site for the few weeks SEOMetrico.

What to do is usually to check that of a crawler sees from your site. As mentioned previously, crawlers aren't humans and they do not see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have a great deal of these in your site, you'd better run the Spider Simulator below to find out if these goodies are viewable through the spider. If they're not viewable, they're not going to be spidered, not indexed, not processed, etc. - in short they will be non-existent for search engines like google.
