How does this benefit you as a marketer?

Market segmentation is the science of dividing an overall market into key customer subsets, or segments, whose members share similar characteristics and needs. Because it involves significant market research, market segmentation can be costly. But it is particularly important for small businesses, which often lack the resources to target large aggregate markets or to maintain a wide range of differentiated products for varied markets. Market segmentation allows a small business to develop a product and a marketing mix that fit a relatively homogenous part of the total market. By focusing its resources on a specific customer base in this way, a small business may be able to carve out a market niche that it can serve better than its larger competitors.
Market segmentation lies somewhere near the middle of a continuum of marketing strategies that range from mass marketing—in which a single product is offered to all customers in a market—to one-toone marketing—in which a different product is specifically designed for each individual customer in a market. Most businesses realize that since no two people are exactly alike, it is unlikely that they will be able to please all customers in a market with a single product. They also realize that it is rarely feasible to create a distinct product for every customer. Instead, most businesses attempt to improve their odds of attracting a significant base of customers by dividing the overall market into segments, then trying to match their product and marketing mix more closely to the needs of one or more segments. A number of customer characteristics, known as segmentation bases, can be used to define market segments. Some commonly used bases include age, gender, income, geographical area, and buying behavior.

Well, for example, let's says  

 a top Internet Marketer comes out with a new product that you review and write up a little article on, and that your competitors do the same.

 Google generally tends to index pages at the start of the month and if you miss that update, you will probably need to wait till the next month to even see your entry in.

But, since your site has RSS feeds, it now gets indexed more frequently. So the chances of getting your page indexed quickly are much higher.
This gives you an advantage over the competition, as your review will show up sooner in the search results than theirs.

Imagine what an entire month's advantage could do to your affiliate sales!
