Understand SEO

No matter if your site is an information, or if it is an online store to sell your products, you want people to come and visit. Without visitors information remains unknown and your products remain unsold. A large portion of web traffic you get is driven by three major search engines: Google, Yahoo and MSN, so it's obvious that you want to have your site coming in the results pages of search engines (SERP). SEO stands for Search Engine Optimization is a set of techniques and practices that will make your website appear on the first page (s) of organic SERPs.

Now that you know what SEO and why it is necessary to better understand SEO you need to get an idea of ​​how the search engines. A search engine is a huge database of indexed web pages that users can query and get relevant results. Thus, a search engine needs:

1. Scans and Web Sites Index. Through automated scripts called robots or spiders, search engines crawl through the Internet find websites and web pages by following links and jumping from one page to another and from one site to another. Once a website is crawled, its contents are indexed in the huge database of search engine.

2. Back to results classified. When a query is made, the algorithm of the search engine finds pages in the database relating to this query and returns the results sorted by most relevant to a minimum.

See how the search engines, it is clear that SEO will focus on words and phrases that users type into the search box and how to make your web pages relevant to those terms and phrases. But because the Internet has become a commercial site, search engines have learned not to rely on websites to be honest about the content of their web pages. That's why SEO should also focus on another factor used in ranking search results: popularity. Your website is popular if others link to it. The most important web site that links to your website is, the "stronger" link. A well-known system for ranking web pages is the Google PageRank algorithm:

"PageRank relies on the uniquely democratic nature of the Web by using the vast link structure as an indicator of the value of a single page. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But Google looks at more than the sheer volume of votes, or links a page receives, for example, it also analyzes the page that casts the vote the votes cast by pages that are themselves "important" weigh more heavily and help a. make other pages "important." Using these and other factors, Google provides its views on the relative importance of pages'. "

So to summarize, SEO is important to build web pages (Internal SEO) and that makes them popular (External SEO) .......
