If you work in the freelance marketing field, global Web positioning can be a lucrative field to specialize in. Even if you are an employee in the marketing department in a Web design agency, this area is a good one to learn about, as the world becomes more interconnected.
Fine-tuning Websites for a global marketplace and researching information on how to maneuver a company into a specific area is something that few people have expertise in. If you set yourself apart as one of those people, it can increase your client base--or if you work at a company--your job security.
Getting the word out about your services may be as simple as teaming up with a Web designer or graphic design agency. Try to approach ones that have an international client list, and see if they have any positions available. If you don't have luck connecting with anyone this way, you can always freelance and highlight your global expertise as a selling point.
