There is no guess work with ST ructure. There are objective rules that apply. A news release, as we know, is written in inverted pyramid-style. The first paragraph is a summary paragraph. It must contain all the essential information.
Subsequent paragraphs provide elaboration.
The paragraphs of a news release are organized in reverse order, from most important to least important, with the last paragraph containing the least important information. Once you know what ST ructure to use for what you are writing, you must determine what ST yle to use. There are rules governing style ,though they are not as objective as those governing structure. Good Public Relations writing, like good journalistic writing, should be clear, simple, economical. Short words, short sentences, short paragraphs.
