How Search Engines Work

What is SEO?
SEO or Search Engine Optimization is the practice of making your website attractive to search engines such as Google, Yahoo, MSN/Bing etc.

Search engines regularly read and archive websites so that people can find them easily. For example, a person may be searching for ways to cook salmon. If your website is about salmon and optimized properly, your site should appear within the first page or two of every search engine.

SEO is the process of making your website easier for search engines to understand. The goal of SEO is increased ranking (see PageRank in First Steps) for your website, which will result in more traffic. Engaging in search engine optimization requires a constantly evolving skill set. This guide contains basic practices that have remained relatively constant over time.

Many people who don't understand SEO or the goals of SEO consider it to be spam or manipulation. However if implemented within search engine guidelines, the practice is endorsed by Google and other search engines. Good SEO results in pages set up in a structured and orderly fashion. The pages will be filled with better information and more valuable content.

How Search Engines Work
Search engines have programs called spiders which visit web pages to determine what the content of your site is, and to find other links to scan at a later date.
Spiders, or web crawlers, scan the content of web pages.
They send the results of their scan back to the algorithm to be broken down and analyzed.
If the spiders encounter a link to another page or website these links are stored.
Eventually other spiders crawl the linked-to pages.
Therefore, the more links from other websites and pages your website has, the more frequently your website is visited and crawled.

By following a complex set of rules and ensuring that we have the correct information in your source code along with keywords and other detailed information throughout a page, a search engine like Google will be able to easily read and catalog (or index) your pages of your website.
