Today when I read news on msn.com I found an article “four ways to stay motivated to slim down.” I felt interested in it and clicked to have a look. Then I found Marketing in the article.
following after each paragraph, some relative products display online for sale. for example, if the paragraph is about setting small goal when you do exercise at gym, some sportwear of some famous sport brands will follow after with pictures, price. And if the paragraph is telling readers to drink more water and eat more veggies, the water bottle and vegetable steamer will follow after for sale.
I think this is an effective promotion and kind of an advertisement on web. Promoting products with relative articles, news, forum and so on can attract more potential customers. In addition this way of promotion just satisfy customers’ needs. Myself can be a good example here. I clicked to read this article just because I want to do exercise to lose weight. So at the same time, I do need some fit activewears. I myself pay attention to these products following after the article. I clicked on The North Face pants to go directly to its brand homepage. At last, I bought this kenetix tight pants. 
However, how will this kind of marketing prometion effect readers who do not buy these products at once? It also has long-term value. Since the target market of sports wear company is people who do and maybe will do exercise, Putting these products after the health, exercise-relatively article is a wise method to promote. Even those readers do not buy these products, they will have some impressions on these products and brands. They will remember some products or brands. Since those readers are potential customers, leaving good image to them can help build good relationships with them all.
