Mark -- I develop content for a living, and I can give it to you in one word. PAIN.
Identify what the pain is to your prospect, and solve that pain. Then they'll give you embarrassing amounts of money and love you.
Most businesses focus on what they want -- increased sales, "branding" (whatever that is), communications, thought leadership, yada yada yada.
Keep your site very very simple and focus on pain, and how you'll solve it.
Here are some examples -- I don't do much soft skills training any more, so I wouldn't be able to give you targeted answers to your industry without doing lots of research. (But the answers are right there in your head, if you can pry them out.)
Plumber: They talk about years of experience, fleets of trucks, nice uniforms, etc. My pain is that the leak is now and my carpets are getting ruined. Focus on that you'll have someone here in 60 minutes, no matter what time of the day or night. And there will be someone right behind to deal with the water on the carpet, the sheetrock that's melting, and the furniture that needs to be moved.
Pet Sitter: They talk about low fees, how much they love dogs, the years they've scooped poop. My pain is that I care about my dogs more than life itself. Send me an email with an attached photo twice a day, showing a happy dog eating his dinner. Take him to the dog park and post a video on you-tube. Teach him a new trick, and show me in a surprise photo. Bring him to the vet and get his nails clipped. I won't every call anyone else.
Hotel (Just experienced this one):
They talk about their rooms, the wonderful restaurant, their valet parking. My pain? I forgot my little "clicker" to make the computer advance to the next PowerPoint slide. At 9PM, I called the front desk and asked if there was a computer store nearby. The clerk offered to have the shuttle bus TAKE ME ON A SPECIAL TRIP to as many stores as necessary to find what I needed. The driver actually suggested a better option, and I presented to 150 people the next day successfully.
If you solve my pain, I'm your friend for life. And you've only got a few seconds when I arrive at your page to offer to do that.
