Answer:
1. The publisher is using the Scare tactic and is trying to scare the public into buying things
Example: "Did you know that if you don't use O-Mega clean then you are destroying the planet!?"
2. The publisher is also using another tactic called the bribe technique which gives people offers to buy things.
Example: “Buy one shirt and get one free”, or “be the member of the "Bumpy Toe Club" for two years and get 20% off on all services.”
3. One other famous technique used in advertising is called "Pester Power & Buzz Marketing". This technique targets children or older people and tricks them into buying it.
Example: "Do you want candy but it's too expensive or your mom won't let you? Then buy "SweetFeet" a new and cheap candy that's 25% off! Just ask your mom or dad to bring you to your nearest shop."
