Search engine optimization (SEO) is the process of improving the rank of a Website or a Web page in search engines. The Websites with a high page rank appear more frequently in the search results. This will result in more traffic to the particular page. Different kinds of search, such as image search, local search, video search, etc. may be targeted by the SEO. This gives presence to a Website on the Internet.

As a marketing strategy over the Internet, the working of search engines and contents searched by the people are considered by SEO. To optimize a Website, one need to ensure the content is user friendly and relevant to his niche and also his website is compliant with W3C standards. This will increase its relevance to specific keywords and will also remove barriers to the indexing activities of search engines.

Web Crawler
A Web crawler is a computer program that is used to browse the World Wide Web in a methodical and automated manner. This process of browsing the World Wide Web is called Web crawling or spidering. Some terms used for Web crawlers are ants, automatic indexers, bots, Web spiders, Web robots, or Web scutters.

The main task of Web crawlers is to create a copy of all the visited pages for later processing by a search engine. The search engine will then index the downloaded pages to provide fast searches.

Crawlers can also be used for automating maintenance tasks on a Web site such as, checking links or validating HTML code, and to gather specific types of information from Web pages, such as harvesting e-mail addresses (usually for spam).

A Web crawler is a type of software agent. It starts with a list of URLs to visit. The list of URLs is called the seeds. As the crawler visits these URLs, it identifies all the hyperlinks in the page. It then adds them to the list of URLs to visit, called the crawl frontier. The URLs from the frontier are then recursively visited according to a set of policies.

SEO Techniques
SEO techniques are classified into two broad categories:

White Hat SEO
White Hat SEO refers to the usage of SEO strategies, techniques and tactics that focus on creating contents for human users, not for search engines. It completely follows search engine rules and policies. Some examples of White Hat SEO techniques are: using keywords and keyword analysis, backlinking, link building to improve link popularity.

Black Hat SEO
Black Hat SEO refers to the usage of aggressive SEO strategies, techniques and tactics that focus only on search engines and not a human user. It usually does not comply with the search engines rules and policies. Some examples of Black Hat SEO techniques are: keyword stuffing, invisible text and doorway pages.
