customers' favorability

Please help me correct the following paragraph. Thanks!

We can see ads everywhere around us. There are all sorts of ads such as food ads, drinks ads, houses ads, car ads, clothes ads, shoes ads, etc. But I see the clothes ads the most. Why do the manufacturers spend a lot of money on advertising? I think it is because they want to increase the visibility of their own products and increase the customer's favorability of those same products, and so as to draw customers’ attention and hope them buy their products. Some people might be so much impressed by the ads as to buy the products. Other people would usually not do that impulsive buy. I need to see the real things which I’m satisfied with and then decide whether to buy. We should make sure we are getting a good buy by shopping around before we make a decision. That is a good way to help us become a smart shopper.
