PR articles and their writing have certain rules. Certain details vary depending on the sites they are published on. The principle is not very high keyword density. It's not good to exaggerate. Writing should be done without spelling mistakes.
PR articles should have headings sufficiently describing and characterizing the following text. No passages should sound cruel and stark. The text should give a good orientation. The Text should definitely be unique. Duplicate passages are very well recognized by bots, and ignored.
Duplicate Pr articles have no beneficial meaning. The robots will reveal them and then ignore them. If you place an article in several different places, you need to change it appropriately to make it always original.
