"Did you know that advertising in specialty magazines gives you much greater results than any other form of print or web advertising? A well-placed ad in one of the speciality mag-azines your target customers love to read can bring you more business than you've ever imagined.
Why are ads in speciality magazines so successful? Specialty magazines reach niche markets. When you narrow your marketing focus to a relevant niche market, you tap into the audience that's actually interested in what you offer. Your ad receives much more attention, and there's a greater chance that what you have to offer is exactly what the readers need or want at this particular stage in their lives."
