Carefully composed and topical articles that contain the keywords and phrases that are part of the controlled search engine optimization campaign are distributed over the internet via article distribution lists that are compiled by free and fee-based article distribution services like PR sites, article submission sites, and other types of content delivery services.
Article distribution lists act like a directory and are generally organized into pre-defined categories by industry. They are usually available free-of-charge to anyone for reading or re-publishing (rules apply).
Article distribution is used in off-page (but still online) search engine optimization to support the overall search engine optimization campaign. See ‘Article Submission Sites’ for further explanation.
