I don’t know if there is a magic formula to placing your novels in the hands of your target audience, but I’ve tried to market in ways to that might expose my books specifically to Boomers as well as the general audience. I’ve joined most of social networks most writers belong to as well as those outlets that cater to age-specific demographics such as classmates.com and eons.com. As a result, I’ve gotten almost 900 additional hits to my profile from Boomer-age people.
On another note, a friend of mine who is a public-health professional was given free tickets to a James Taylor concert last year. It turns out the concert was sponsored by a company that makes heart defibrillators. What a clever tie-in that was to reach that demographic! That’s the kind of ideas I’m striving for.
