If you enter a query in a search engine and hit 'enter' you have a listing of web results that have that question term. Users normally often visit websites which are towards the top of this list while they perceive the crooks to be more strongly related the query. If you have ever wondered why many of these websites rank superior to the rest then you certainly need to know that it must be due to a powerful online marketing technique called Seo (SEO) que es SEO.

SEO is really a technique which helps search engines find and rank your site above the countless other sites in response to a search query. SEO thus assists you to get traffic from search engines like google.

1. How Engines like google Work

The very first basic truth you need to know to understand SEO is that search engines usually are not humans. While this could be obvious for everyone, the differences between how humans and look engines view website pages aren't. Unlike humans, engines like google are text-driven. Although technology advances rapidly, search engines like google are definately not intelligent creatures that may notice the appeal of a cool design or take advantage of the sounds and movement in movies. Instead, search engines like google crawl the world wide web, taking a look at particular site items (mainly text) to have a concept what a website is about. This brief explanation isn't most precise because when we will see next, search engines like google perform several activities so that you can deliver serp's - crawling, indexing, processing, calculating relevancy, and retrieving.

First, search engines like yahoo crawl the Web to view what's there. This is completed by way of a software package, referred to as a crawler or possibly a spider (or Googlebot, out of the box the truth with Google). Spiders follow links from page to a new and index everything they find enroute. Having in your mind the amount of pages on the internet (over 20 billion), it's impossible for the spider to check out a site daily in order to determine if a brand new page has appeared or if a pre-existing page continues to be modified, sometimes crawlers might not exactly wind up visiting your site for a month or two SEOMetrico.

What you can do is usually to check exactly what a crawler sees from a site. As already mentioned, crawlers are not humans and they don't see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have plenty of these on your site, you'd better run the Spider Simulator below to see if these goodies are viewable from the spider. When they are not viewable, they won't be spidered, not indexed, not processed, etc. - in short they'll be non-existent for search engines.
