Website Search Engine Optimization - SEO
Search engine optimization (SEO) as a subset of search engine marketing seeks to improve the number and quality of visitors to a web site from "natural" ("organic" or "algorithmic") search results. The quality of visitor traffic can be measured by how often a visitor using a specific keyword leads to a desired conversion action, such as making a purchase or requesting further information. In a broad sense, SEO is marketing by appealing first to machine algorithms to increase search engine relevance and secondly to human visitors. SEO, however, does not necessarily imply that the content itself is favorable to algorithms at the expense of human visitors; a subfield within SEO concerns itself with optimizing a site's presentation and structure, without making noticeable changes to human visitors. The term SEO can also refer to "search engine optimizers", an industry of consultants who carry out optimization projects on behalf of clients.

Web site Search Engine Marketing - SEM
In Internet marketing, search engine marketing, or SEM, is a set of marketing methods to increase the visibility of a website in search engine results pages (SERPs). The three main methods of SEM are:
- Search engine optimization attempts to improve rankings for relevant keywords in search results by improving a web site's structure, content, and relevant backlink count.
- Pay per click advertising uses sponsored search engine listings to drive traffic to a web site. The advertiser bids for search terms, and the search engine ranks ads based on a competitive auction as well as other factors.
- Paid inclusion can provide a guarantee that the website is included in the search engine's natural listings. However, as of 2006 the leading search engine, Google, does not offer this service.
