The objective of Search Engine Optimization is to increase web visitor counts by ranking very high in the results of searches using the most appropriate keywords describing the content of your site. This relative ranking is often viewed as a struggle to best use a few keywords, instead of a struggle to out-do your competition. If you search on your target keywords, you will see the leading site in the rankings. All you need to do is to be better than that number one site.
It is not enough to simply add META tags and do search engine submission of your site to a million search engine indexes and directories. The first placement step in obtaining significant web visitor counts is to seek first-page search engine results. An early step is to build a great content-rich site. One of the last steps is the proper submission of your great site to the search engine or directory. In the middle is a step that is VITAL if you want to obtain front-page results. Most sites skim past this step because it is forgotten or too complex, but without competent Search Engine Optimization you are destined to be search engine fodder.
