Product positioning means to give a product or service a certain status of recognition with relation to the status of other product or service that is generally known.
Positioning is used both in marketing and public relations.
Isn't there too much advertising around?
As a matter of fact people are overwhelmed with the amount of advertising and promotion happening on TV, radio, internet, billboards, flyers, sales letters, postcards, coupons, emails, newspapers, etc.
The truth of the matter is that there is no room for anything new except what people got already used to.
They know what works for them and nobody will make them change their habits unless they will feel the necessity and desire to do so.
In marketing there is a technique to influence people's minds and have them willingly accept and buy the things offered. It is to position a product or a service for or in favor of or against something that people already know.
There are lots of well known brand names that people regularly shop for and there are also a few methods to position in a way so that it gets home to people.
Conducting a professional research is parallel the key to getting results that are able to cause people to want products or services being advertised.
Research is the most important part here because it is the source and the workability of your campaign will depend on the precision of the data of your positioning research.
Assuming won't work as it is "may be" - may make it or may not. Why risking?
The right thing to do is not to assume but know the facts.
