PR articles are intended to increase the reader's awareness of a particular problem, service, product or company. These are promotional purpose texts, which should be in a form indistitable from ordinary texts. It should not come to know that this is an advertisement.
The goal is to write such PR articles, for which the reader has no idea that this is a purpose-built promotional text. They should have a readable content and form, something to attract, and not be duplicated. Duplicate content is easily recognized by the search engine, and such articles have no meaning. The content must always be unique.
Writing PR Articles
Writing PR articles should be a person who has a good control of the language, because spelling mistakes will not bother anyone, and certainly does not improve the reputation of the company. It is advantageous to use synonyms, so that some words still do not repeat.
