In the world of web designing, nothing is quite as hot right now as search engine optimization (SEO). SEO is a marketing strategy that heavily relies on web design and development to get off the ground. What is SEO, exactly? SEO is the process of designing websites and building content that best grabs the attention of search engines such as Google and Bing. The objective here is to be featured prominently (ideally first) on a search results page. The higher the ranking, the more traffic (and ultimately customers) a website will receive.
