The marketers practice their profession every day and they then become the expert in their profession, no matter what products they go to market. Some of the marketers change their strategy a lot and some of them stick to one which they find perfect for them to go with.
While going to sell something; they often be criticized by their customers on the prices they ask for their products. Marketers who have different strategies, use more than one with their customers and soon be able to lock the deal whereas marketers with single strategy find it difficult to respond to the regularly received criticism.
Using different sources and strategies is one way of marketing and sticking to a single strategy is the other. Both these marketing ways are effective and fruitful equally because we never know which strategy works with which customer and we can also say that a single strategy can suffice numerous customers as well.
So for having a successful marketing tip or strategy, there is always a single way whether it is there without any other choice or been chosen from a variety of ways. The most important thing to remember all the time is to value yourself in whichever way we choose to lock the deal.
