The next most effective way is through the media. When they publish one of your press releases you gain instant credibility and massive exposure. Publishing your own ezine on a regular basis, whether daily, weekly, monthly or at whatever interval, keeps you in the minds of your current and prospective customers. It also establishes your credibility as an expert in your chosen area. When you write articles and have them published it establishes you as an expert on the subject about which you are writing.
Most publishers are very selective concerning the articles they choose for their publications.
This gives you publicity and broad exposure. Credibility is an added plus. These ads are published in ezines and off line media and distributed to people who are subscribed to them. Because they have subscribed, or opted to accept these items, they are much more likely to read and respond to them. Without a well-written and effective ad, none of the above methods will provide suitable results.
