Search engine optimization (SEO) is the technique of manipulating search engines to boost traffic a website via unpaid or natural search results as opposed to search engine marketing which one has to pay for paid inclusions. Typically if your site is ranked higher on the search engine results page, the more click throughs you will receive from the search engines. SEO can target many types of different searches, including local search, image search, video search, and soon mobile search.
As an Internet marketing strategy, a qualified SEO understands how search engines work on displaying search engine results and what people tend to search for. Search engine optimization primarily involves two factors.
On page optimization of content and associated coding to increase its relevance to specific keywords. The list may include page title, meta description, meta keywords, meta robots, canonical URL tag, page architecture, heading tags, keyword density in body text, internal linking, site navigation structure, URL naming, and domain name extension.
The second factor would be off page optimization which typically deals with off site promotions. The list may include search engine submissions, local directory submissions, community creation in social networking sites, blogging, forum postings, social bookmarking, link exchange, link baiting, cross-linking, photo sharing, video promotions, business reviews, article submission, press release promotion, classifieds submission, social shopping network, question and answering sites, document sharing, CSS W3C and RSS directory submissions, widget/gadget development, and pay per click advertising campaign.
