Pretty simple, huh. And if you don’t know ask them. Your clients’ reading habits will reveal what it is that other potential clients like them (whom presumably you would like to also represent) are reading. That is essentially the message of today’s meditation taken from 365 Marketing Meditations: Daily Lessons for Marketing & Communications Professionals by my friend Larry Smith and Richard Levick of Levick Strategic Communications, to wit:

What do your clients read? If you don’t know the answer, you cannot know what they need to hear from you. If you don’t know the answer, you cannot know how to reach them with that information.

As I said, one way to find out is to ask them. Then, seek out the editors of those publications and find out if they accept outside articles for publication. Don’t stop there. Read the publications for content and style, so that you can write on topics that their readers (i.e., your clients and potential clients) are interested in. Yeah, that’s pretty simple.
