Search Engine OptimizationSearch Engine Optimization (SEO) is the art of creating web pages that will rank high in search engine returns.
SEO is achieved by optimizing certain sections or “elements” of the coding read only by search engines on each page.
There are various theories about how a web page should be optimized and opinions differ. Much will depend on your type of site, its content, purpose and competition.

Generally, search engine optimization relies heavily on the proper use of keywords and keyphrases that describe the site’s content.
The keywords can either be placed in sections or elements aimed specifically at Search Engines or in sections visible to all as part of the text.
Search Engines will crawl through each webpage, looking for any information relevant to understanding what the website / page is about, so it is important that keywords and keyphrases are accurate so that the site appears when users search under particular criteria.

Keywords in my BODY.
An important location for keywords is in the header fields (H1, H2, H3…) of each page. The most important keywords or keyphrases should be found here.

Other tricks for helping SEO are naming image files and anchors (crosslinks within the same page) with keywords.

Useful “friends”
Finally providing links to and from external sites, called backlinks is also important, as search engine spider bots navigate by links. The text in your page that points to external links can contain keywords too.
Since SEO relies so heavily on keywords, the most important keywords and keyphrases should be used abundantly in the first and last two paragraphs of the content of each page, then scattered throughout the body. A keyword density (describe what this is, eg. 5 words per 100) between 5 to 15% is ideal.

SEO a necessary start.
With the billions of web pages on the Internet and the hundreds or even thousands of “hits” that can be returned from any single online search, SEO is a necessity for anyone looking to benefit from search engine traffic. In the long term, the popularity and/or financial investment will help your website make its way to the top of any search provided that the SEO was done appropriately.
