Cover letters for free-lance web developers can be a little tricky as you want to convey professionalism in an industry known for its quirky creativity. If you need to improve your cover letter for a web developer free-lance job, begin by answering the question, what can you do for this company? Can you generate more hits for their site? Can you simplify their e-commerce? Can you modernize their decades old design? Write your answer in your cover letter. For example, "I can ensure that you have a mobile optimized website," tells the company how you can help them improve. Then you can write a few sentences about companies you are currently serving and the kind of work you have done for them. If you have any mutual acquaintances for whom you have worked, it doesn't hurt to mention names. It gives your free-lance work a little more validity. It's also good to study examples of free-lance cover letters
