Explanation:
In persuasion, we try to make our audience to take a call to action. We give reasons why our product is better than every other in the market. At the point of persuasion, lies and unnecessary exaggeration should be avoided. This is to avoid customers getting a product without the features that were mentioned in the advert.
When we speak persuasively, we try to make people go with our own decisions.
