It is well neigh impossible to estimate precisely the number of world wide web (www) pages on the internet but there are truly a great many and this makes finding relevant information quite complex. Search engines and indexes were created to help people with this task. The search engines' aim is to return good matches for their users' queries and relevant pages quickly. On the other hand, the author of a web page has a vested interest in it rating highly, for appropriate queries, on as many search engines as possible.
There are millions of searches being performed on the Internet per day, most of which are looking for exactly what you propose to sell. Search engine optimization (SEO) is the process of improving the volume and quality of traffic to a web site from search engines via search results. Usually, the earlier a site is presented in the search results, or the higher it "ranks," the more searchers will visit that site. SEO is considered to be the best cost-effective alternative among all forms of marketing which is prevalent today.
Online search is the most widely used method of attracting qualified visitors to any Web site. According to Jupiter Research, 82% of online shoppers know exactly what they want when they log on to the Internet, and almost half of them use search engines to find solutions and vendors. With research confirming that the vast majority of searches end within the first two pages of results, prominent placement on the Internet's major search engines through effective search engine optimization is of critical importance
Search optimization requires thorough research and analysis besides updated information and experience of how the algorithms and web-spiders of various search engines functions. Some of the processes involved in carrying out SEO are provided below.

Keyword Analysis
Knowing what words and phrases people use to search the Web is an essential component of any well-executed search engine positioning campaign. The keyword analysis is meant to identify the proper keywords suitable for a business to ensure that the most qualified users will find the specific pages within a site that are relevant to their specific search query.

Competitive Analysis
The competitive analysis provides the tools necessary to achieve and maintain your rightful position at the top of the search engines. This phase of the search engine optimization (SEO) process yields the foundational data necessary to achieve the competitive advantages needed to outperform your competitors on the search engines and gain valuable market share.

Content Enhancement
Content enhancement involves the modification of Website content. During this phase of the process, the current placement of existing content is manipulated, new content is added/edited, or existing content is even removed in certain circumstances. Since the end aim of the Search Engine Optimisation process is to achieve prominent placement for the right keywords rather than tricking the search engines; it is ensured that the appropriate keywords are incorporated into the website in correct manner.

Code Enhancement
Effective copywriting is only part of the process when it comes to making a Website search engine friendly. Regardless of how complex search engines seem, they are not yet complex enough to read all content that the web browsers display. While flash, Java script, DHTML, and framing technologies may look great to the end user, they can stop a search engine dead in its tracks and prohibit a Website from being visited effectively. Search engines rely on specific code to determine the content within a Web page.

Link Enhancement
Once the content contained within a site is geared towards the appropriate keywords and search engine spiders are effectively navigating a site, the search engines will attempt to determine it’s relative importance with respect to other web sites. This is called “Page Rank” in Google terminology. Relevancy based search engines use linking to determine the relative credibility of one site versus another with respect to subject matter and content correspondence. Enhancing these links can have substantial impact on your ability to achieve and maintain prominent positioning for the keywords you covet.

Web Page and Directory Submission
The final step in the search engine optimization process is to make sure that each of the newly optimized pages is included in the indexes of all the relevant search engines. Directory submission requires both effective copy writing and a comprehensive understanding of the search engines.
