An executive search firm could provide articles on successful interviewing. A good way to feature products and services is through customer success stories. Describe how a product or service helped a customer. Write a case study about how your services improved a client's business. Or interview satisfied customers to have them share their experiences with your products and services.
Busy professionals look for ways to keep up with their fields.
Providing updates, trends, and analysis of your industry can be a valuable service for your visitors. For example, a Human Resources consulting firm could provide labor law updates on its web site. Consider posting questions on a site bulletin board to make the site more interactive. To attract and retain web visitors, you need content that your target audience will find useful.
