When the World Wide Web began, web developers either developed online content themselves, or modified existing documents and coded them into hypertext markup language (HTML). In time, the field of web site development came to encompass many technologies, so it became difficult for web site developers to maintain so many different skills. Content developers are specialized web site developers who have content generation skills such as graphic design, multimedia development, professional writing, and documentation. They can integrate content into new or existing web sites without using information technology skills such as script language programming and database programming.
Content developers may also be search engine optimization specialists, or Internet marketing professionals. High quality, unique content is what search engines are looking for and content development specialists therefore have a very important role to play in the search engine optimization process. One issue currently plaguing the world of web content development is keyword-stuffed content which are prepared solely for the purpose of manipulating a search engine. This is giving a bad name to genuine web content writing professionals. The effect is writing content designed to appeal to machines (algorithms) rather than people or community. Search engine optimization specialists commonly submit content to Article Directories to build their website's authority on any given topic. Most Article Directories allow visitors to republish submitted content with the agreement that all links are maintained. This has become a method of Search Engine Optimization for many websites today. If written according to SEO copywriting rules, the submitted content will bring benefits to the publisher (free SEO-friendly content for a webpage) as well as to the author (a hyperlink pointing to his/her website, placed on an SEO-friendly webpage)
