SEO is the process of improving the volume and quality of traffic to a website from search engines through "natural" or "organic" search results for the targeted keywords.
Natural SEO may be just a part of an internet marketing strategy but however, a fundamental one. It is the baseline for your online success. With SEO you can increase the number of quality visitors, who are genuinely searching for your service or product.
Search Engines are the most effective way to get your website noticed by potential customers. Search Engine Optimization or SEO is a science that analyzes search engine algorithms and human visitor behaviour to get your website top rankings on major search engines like Google, Bing, and Yahoo.
SEO is also the art of using Meta tags, organic positioning of keywords in the body text, analyzing keyword density using popular SEO tools and techniques. However, top search engine rankings can only be achieved by SEO experts who, like doctors, use experience, natural instincts and common sense to devise the most appropriate Search Engine Optimization strategy. Their approach is also based on research, target audience, website content, competitor analysis etc.
