Like a lot of professions, copywriting can be specialized. A B2B copywriter is a specialist. B2B means business to business. Therefore a B2B copywriter is someone who writes for business to business industries. What do we mean by business to business? It simple means companies that deals only with other businesses in the supply of goods and services.
One cannot be a jack of all trade. Some people specialize as a B2B copywriter. Some body else may specialize as a business to consumer copywriter. Both industries are quiet different. A consumer searching to buy the latest iPad will be completely motivated in a different way from the VP of a mid size company wanting to buy an additional truck for their delivery system.
B2B copywriter specializes in an industry
The B2B copywriter addresses a very specific market. Most of them furthermore specializes in industries, for example the software industry or the oil industry, aircraft industry. Each of those industries have their own markets, technologies, and lingo. Understanding the software industry is not the same thing as understanding the oil industries.

Being able to communicate with marketing directors is an essential part of the work. There are many steps involved in the process of persuading him to spend a couple of million dollars on a product. Very different goal than in the consumer world.

One has to know the different marketing pieces that would be needed to be done in a B2B copywriting. In a nutshell a certain real world experience is important.
