Assessment of publicity
Public relations are aimed at the whole environment, not just to consumers, and their main function is to maintain two-way communication with the environment. PR therefore can not be reduced to mere disclosure and public statements, but also includes monitoring of the reaction, ie public opinion and especially opinions of the target population. From public relations to a great extent depends the publicity.
What other media are reporting about you is more important for you and your customers of what you have to say about them. Publicity is considered to be independent and it can acquire additional promotion, of course, if the publicity is positive.
Likewise, if the publicity is negative, it can destroy all the efforts in advertising.
