Have a form on your site that visitors need to fill out in order to gain access or use an auto-responder to deliver it. Beyond content, offline traffic generation is just as important. And the first rule in doing so effectively is to specialize. The most common mistake newcomers to any field of business make is to think that by expanding their portfolio they will secure more business, and nothing can be further from the truth. Specializing and narrowing one's focus as much as possible will paradoxically broaden the likelihood of your site getting more hits let alone business.
Specialization is in itself a fundamental marketing process.
For instance, an accountant specializing in car dealerships will get more traffic than a general accountant will. A photographer specializing in weddings will get more hits than a regular photographer will. And the list goes on and on. Therefore, have your site focused on a niche, a specific theme, or a particular concept. Think of a laser, which is basically a beam of highly concentrated light.
