Techniques

Different types of techniques are hidden and overt messages , emotional responses or accusation and celebrity endorsement.

Hidden and Overt messages.
Hidden- Insinuated.
Overt- Obvious / clear message.
Hidden messages are messages that are subliminal. They are something that you do not realise what its saying. For example in the cilitbang advert's overt message is that cilitbang will make your house clean. Its hidden message is that its powerful, easy and it leaves women in control of what they are doing.

This adverts overt message is that the product that they are selling is really good at getting out stains. However it contains some hidden message's. A hidden one is that if you use that product your family life will be better, the kids will always have fun. It gives hint that if you use persil family life will be perfect. Even though as a viewer we know that family life is not perfect but it still sinks in subconsiesly.
Emotional
The advert makes you believe that the product is a solution to a problem the viewer might/will have. The advert makes you question a problem, it makes you believe that the problem is big and if you buy the product the problem will go away. It makes you say "Do i need this in my life?" and by the end of the advert the customer will be saying "Yes, i do"

Fear or concern
They use fear as a tool for control. A lot of time you see this in adverts that are on about the public health such as smoking and drink driving. Not many adverts use this as it is quite a serious advert and the company has to be careful how they use it. They have to be careful as they do not want to offend the customer. But fear is a powerful way in which they can control people ,that is why governments like to make sure they make a problem bigger than it actually is.

This is an advert that is based around the concept of fear. When the boy looses his mother he starts to get upset. This can make the parents who smoke start to feel concerned that if they carry on smoking then their child will be like the one on the screen. This then turns into fear when they start to think "who will look after my child why i am gone?" This is a very powerful way in which the goverment can persuade people not to smoke.

Compassion
these adverts make sure the advert shows care , love and compassion to persuade the viewer to buy their product. A lot of the time it is associated with people who are in need. It makes the reader feel guilty and upset about what they have been showed. A lot of the time these types of adverts are trying to persuade you to donate money to a particular charity.

This advertisement is a compassionate advert as it contains a man explaining to his son that he wont be there anymore. It makes you feel more upset as it is in an everyday environment is it is totally believable. What makes this advert more emotional is that the son only looks young and at the end we actually see the mother telling him in the back ground that he is gone.
Celebrity endorsement 
It is a popular technique that companies use to persuade the viewer that they want the product. They use this technique to link the product with the reader. It is also a really cheap way of advertising because all they really need to do it pay the celebrity and that is really it. This also includes hidden and overt messages as it makes the viewer think "If i buy this product i will be like this celebrity".

This is a good celebrity endorsement as it has Ashton Kutcher in it.  Ashton Kutcher is an American actor mostly known for his role in "that 70's show". With him in it fans will want to go out and buy the camera and feel like they are closer to Ashton. This also makes the ad cheaper because they do not have to do anything special because it already contains a celebrity so in a way the product is already sold.
