If you’re writing nonfiction, you’re probably trying to zero in on a category or topic that you’d like to write about and be known for. You’re trying to find your focus.

If you haven’t already been exploring the possibilities by writing blog posts or articles, you’ve probably had some inkling. If not, look for clues.

When you’re leafing through a magazine, what articles catch your eye? What do you rip out and stick in a folder? When you’re skimming your Twitter or Facebook feed, what do you retweet or share? What do you save to Pocket or Evernote?

What Topics Fascinate, Captivate, or Energize You?

Make a list of those fascinating, captivating, energizing topics—the ones you return to again and again.

Once you’ve identified those topics or categories, you have some choices. For example, do you see a common thread that ties them together? If so, see if you can create an umbrella under which they can fall.

Lifestyle bloggers do this, where under that “umbrella” they have categories on their website—buttons or tabs to click on—for things like “travel,” “health,” “style” and “photography.” A mom-blogger “umbrella" might have these for “recipes,” “crafts, “money-saving tips” and “organization.” It all depends on the things you love and want to write about—the things that fascinate, captivate, and energize you.

Narrow Your Categories

A couple of things may help you at this point.

First, as much as possible, consider narrowing down—or “niche-ing down,” as they say—to stand out in a crowded online world. You can try to enter the lifestyle blogger world, but by narrowing, you’ll make it easier for people to find you and your focused topic.

You can narrow by the audience or reader you find yourself drawn to—or the readers drawn to you already if you’re out there writing now.

Or, you can narrow the topic to a subtopic and focus on that.

For example, instead of “travel," which is a big, crowded category, maybe you focus on frugal travel tips—that’s narrowing the kind of travel, but even that’s kind of a big category. How about frugal travel tips for young families? That’s narrowing the target audience. You could mix and match given who you are, what you’re drawn to, and the people you want to reach.

Maybe you want to offer frugal travel trips for big families, or frugal travel tips for retirees. Or singles. Or maybe you want to focus on camping for big families. You see how you can narrow the topic and the audience or reader? That’s niche-ing down.

To illustrate how this will work to your advantage as a blogger or writer, consider this: If I want to find an article about frugal camping tips for big families, am I going to be more inclined to dig into a lifestyle blogger’s website that has high-end photography tips and craft beer recommendations as well as three or four camping articles under their broad “travel” category?

Or am I going to spend some time digging into the resources I find at a blog offering all kinds of camping tips for big families? Chances are, I’m going to bookmark that second website and return to it. I’m going to pin their stuff on Pinterest and share it on Twitter.

That’s the power of narrowing or niche-ing down—the people who need that specific information, and the people who care about a certain subject or the people who are captivated by certain types of stories, will come to you: the one writing exclusively about it.

If You're Feeling Constrained

A frustration I’ve heard is that this narrowing feels constraining to some writers. It’s like I’m asking you to be a bookseller crammed into a tiny rented space squeezed in next to a barber shop with barely enough room to sell just one category of books, like mysteries. But you do it. You’re fascinated with mysteries,
