If you are an owner of popular website (example; blog and social networking sites) you can make money by offering advertising spaces to business owners who are selling products and services that your visitors might find interesting. Here's what you need to do:

1. List building. The first thing that you need to do is to capture the contact information of those business owners who might be interested to advertise on your website. If your site's theme is about pregnancy, you may contact OB-gynecologists and companies that sell baby items. You can check the yellow pages, buy list from online companies, or build your own. Just make sure that your list is of high quality. You wouldn't want to waste your time and energy on those people who are not really interested on what you offer, right?

2. Email marketing. The next thing that you need to do is to create a compelling email ad. This must contain all the benefits that your potential advertisers can get should they decide to post their ads on your website. I recommend that you give them an idea as to how much it will cost to advertise on your site. Make sure that you give them a phone number to call should they have any question or should they decide to sign up.

3. Telemarketing. If you want a more aggressive approach in selling advertising spaces, I recommend that you hire telemarketers who can help you out. Their job is to do cold calls to secure appointments. You'll come in when these people are able to convince your prospects to meet up with you.
