Search Engine Optimization (SEO) is the process of improving the visibility of a website on organic (“natural” or un-paid) search engine result pages (SERPs), by incorporating search engine friendly elements into a website. A successful search engine optimization campaign will have, as part of the improvements, carefully select, relevant, keywords which the on-page optimization will be designed to make prominent for search engine algorithms. Search engine optimization is broken down into two basic areas: on-page, and off-page optimization. On-page optimization refers to website elements which comprise a web page, such as HTML code, textual content, and images. Off-page optimization refers, predominantly, to backlinks (links pointing to the site which is being optimized, from other relevant websites).
Types of SEO
As the colors of the types of search engine optimization suggest, there are stark differences in the approach and long-term results of white hat and black hat search engine optimization. Though both types of SEO have their proponents, most companies/websites with long-term, stable, and sustainable goals will tend to stay away from the dark-colored variety.
White hat SEO utilizes techniques and methods to improve the search engine rankings of a website which don’t run afoul of search engine (mainly Google) guidelines.
Black Hat SEO exploits weaknesses in the search engine algorithms to obtain high rankings for a website. Such techniques and methods are in direct conflict with search engine guidelines.
