What's SEO?

When you enter a query into a search engine and press 'Enter', you get a list of web results that contain the query term. Users normally tend to visit sites that are at the top of this list because they perceive them more relevant to the query. If you've ever wondered why some of these sites rank better than others, then you know that this is due to a powerful web-marketing technique called Search Engine Optimization (SEO).

SEO is a technique that helps search engines find and rank your site higher than the millions of other sites in response to a search query. SEO helps you get traffic and search engine.

This guide covers all the SEO information that you need to know about search engines - that is, how it works and the differences in classification criteria and the major search engines.

1. How Search Engines Work

The first basic truth you need to know to learn SEO is that search engines are not human. While this may be obvious to all, the differences between how humans and search engines see the web pages are not. Unlike humans, search engines based on text. Although technology is advancing rapidly, search engines are far from intelligent creatures that can feel the beauty of a design or enjoy the cool sounds and movements in the movies. Instead, search engines crawl the web, looking at the particular site items (mainly text) to get an idea of ​​what is a site. This brief explanation is not accurate because, as we shall see, search engines perform several activities to provide search results - Crawling, indexing, processing, calculating relevancy, and recovery.

First of all, search engines crawl the Web to see what's there. This task is carried out a piece of software called crawlers or spiders (or Googlebot, such as Google). Spiders follow links from page to page and the index of all find their way. Given the number of pages on the Web (over 20 billion euros), it is impossible for a spider to visit the site every day just to see a new page has appeared, or if the current page is changed, sometimes crawlers should not be stopped even visiting your site a month or two.

What you can do is check what a crawler sees from your own site. As already mentioned, the robots are not human, and they can not see images, Flash movies, JavaScript, frames, password-protected pages and directories, so if you have tons of these on your site You better run Spider Simulator below to see if these goodies can be seen by the spider. If they are not visible, they are not spiders, not indexed, not processed, etc. - in other words, they will be absent for the search engines.

After a page is crawled, the next step is to index the contents. The linked page is stored in a huge database from which it can be retrieved later. Netherlands, is the indexing process to identify words and phrases that best describe the page and assign the page to particular keywords. For a man will not be able to manage such volumes of data, but generally search engines treat this task as well. Sometimes they could not get the importance of a page, but if you help them by optimizing, it will be easier for them to categorize your pages properly and for you - to get a better ranking.

When a query is the search process - that is, comparing the search string in the search query with pages indexed in the database. Since it is likely that more than one page (which is virtually millions of pages) contains the search string, the search engine starts calculating the relevancy of each page in its index with the search string.

There are various algorithms to calculate relevancy. Each of these algorithms has different relative weights of common factors such as keyword density, meta tags and links. This is why different search engines give different search results pages for the same search. Moreover, it is a known fact that all the major search engines like Yahoo, Google, Bing, etc. periodically change their algorithms, and if you want to keep on top, you also need to customize your pages for recent changes . This is one reason (the other is your competition) to devote efforts to SEO, if you want to be on top.

The final stage of the activity of search engines is the result of recovery. Basically, there is nothing more than shown in the browser - ie search results pages that are most relevant infinite ordered to relevant sites.

2. The Differences In The Major Search Engines 

Although the basic principle of operation of all search engines are the same, small differences between them will lead to major changes in the relevance of the results. Several different search engines are important factors. There were times, when SEO experts joked that the algorithms Bing deliberately made the exact opposite of Google. While this may be a kernel of truth, is something that the big search engines like different things and if you're going to win more than one of them, it is necessary to improve the accuracy.

There are many examples of differences between the search engines. For example, Yahoo and Bing, is a page of key factors are of paramount importance, while the Google links are very, very important. Google Sites also are like wine - a parent, the best, although not usually Singapore preferences to websites and domain names in the tradition (eg the elderly). So you may need more time before the site gets ripe to be taken to the top of Google, like Yahoo.
