SEO (Search Engine Optimization)

seoAs you search for a text on google you get a list of web results. You would naturally visit websites that are at the top of this list as they perceive those to be more relevant to the query. If you have ever wondered why some of these websites rank better than the others then you must know that it is because of a powerful web marketing technique called Search Engine Optimization (SEO).

How Search Engines Work ?

  • The first basic truth you need to know that search engines are not humans.
  • Search engines crawl the Web, looking at particular site items (mainly text) to get an idea what a site is about.
  • Search engines crawl the Web to see what is there. This task is performed by a piece of software, called a crawler or a spider (or Googlebot, as is the case with Google).

Spiders follow links from one page to another and index everything they find on their way. Having in mind the number of pages on the Web (over 20 billion), it is impossible for a spider to visit a site daily just to see if a new page has appeared or if an existing page has been modified, sometimes crawlers may not end up visiting your site for a month or two.
