Copyrighting is when certain words or phrases are used to promote a person, business, opinion or idea. The word copy will usually be applied to mean when something, for example a body of text, has been repeated and printed, such as in a Newspaper article or a book. However, the term copywriter is usually restricted to promotional situations, where the user will benefit from the copyrighting. This means that newspaper reporters and writers are not regarded as infringing copyright.

Content writing on websites is also known as copywriting, and is improved through search engine optimisation.
The purpose for the copy is to attract the reader towards their particular product, service or viewpoint. In other words: to persuade the reader to buy a product or force an opinion upon them. On the flip side, the copy could have the purpose to dissuade the reader, for whatever field it may concern.

Copywriting appears in all manners of marketing communications media. These will include postal mail, online advertisements, postcards, catalogs, billboards, television and radio commercials, e-mail content, sales letters, web-content, taglines and press releases.

The text which appears on websites is known as text, and the author of this is called a content writer. This content writing is also referred to as copyrighting. One main objective of this is to achieve higher rankings within search engine results. This is known as search engine optimisation (SEO) and involves the practice of strategic placement and repetition of keywords and keyword phrases on the web pages. This is done in a way that is not apparent to the human reader and one who carries out this practice is known as a search engine optimiser.
