1. Place advertisements on websites that have substantial content related to your company or product. In the most basic sense, you would advertise a new dog collar on a site related to dogs.

2. Have ads placed in specific sections of websites to target a more specific audience. This works well on web portals and social networking sites. For example, you could advertise your mortgage company on the real estate page of a larger web portal.

3. Use keywords to place ads on pages with related content. Using target advertising companies, such as Google Adwords, you can place your ad on websites that will best promote your product. You should select keywords that are as specific as possible to get the best bang for your buck.

4. Explore the many cost-per-click or affiliate programs available. While companies that work with keywords provide the most targeted audience, basic affiliate programs, which allow users to choose ads to match their site, also provide a good return on advertising.

5. Consider providing an opt-in newsletter to your website’s visitors. If you have lists specific to certain genres or groups of customers, direct emails can be useful to round out a targeted advertising campaign.

6. Build credible content on your site, the more personal, the better. Providing a regular blog or frequent articles that attract a specific audience is the most basic form of targeted advertising. The content on your website can promote your product and bring in prospective customers.

7. Post in forums or hire someone to do so. Using knowledgeable posts to advertise your company or product in related threads is an inexpensive and effective form of targeted advertising. Be sure that your posts do not come across as only advertising. Instead, try to provide helpful solutions and general comments while also mentioning your company.
