Introduction - Precisely what is SEO

Once you enter a question in a search results thus hitting 'enter' you recruit a set of web results that have that query term. Users normally tend to visit websites that are towards the top of this list as they perceive those to be a little more tightly related to the query. If you've wondered why many of these websites rank much better than the others then you certainly must know it is caused by a powerful web marketing technique called Search engine optimisation (SEO) que es SEO.

SEO is often a technique which will help search engines like yahoo find and rank your internet site more than the countless other sites in reaction to a search query. SEO thus can help you get traffic from search engines.

1. How Search Engines Work

The 1st basic truth you should know to find out SEO is the fact that search engines like yahoo are certainly not humans. While this may be obvious for everyone, the differences between how humans and check engines view web 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 could glance at the appeal of a cool design or benefit from the sounds and movement in movies. Instead, search engines like google crawl the net, taking a look at particular site items (mainly text) to have an idea exactly what a website is about. This brief explanation isn't the most precise because as we will see next, search engines like yahoo perform several activities in order to deliver listings - crawling, indexing, processing, calculating relevancy, and retrieving.

First, search engines like yahoo crawl the internet to see what's there. It might be is carried out by the software program, known as a crawler or perhaps a spider (or Googlebot, as is also the truth with Google). Spiders follow links from page to another and index everything they find enroute. Having in mind the volume of pages online (over 20 billion), it really is impossible for a spider to visit a web site daily only to find out if a whole new page has appeared or maybe a pre-existing page has been modified, sometimes crawlers might not find yourself visiting your site for any couple of months SEOMetrico.

You skill is to check such a crawler sees out of your site. As mentioned above, crawlers are not humans and they also do not see images, Flash movies, JavaScript, frames, password-protected pages and directories, if you decide to have a great deal of these on the site, it is recommended to run the Spider Simulator below to see if these goodies are viewable from the spider. If they're not viewable, they will not be spidered, not indexed, not processed, etc. - in a word they shall be non-existent for search engines like google.
