But this elevator is FAST. You have less than two seconds to get your readers' attention, and once you have it, you have less than 15 seconds to give them the pitch.
Imagine your elevator pitch sounding something like "um, I'm all things to all people. I kind of solve any problem that anyone has." You can already see eyes glazing over. Now imagine responding with something like "I help women over 50 smash the glass ceiling." There are two things that have changed between the two statements.
You have specialized
It's fine for your website to talk about your broad range of skills. Don't make this the top point though. Your specialization will attract more clients than your general aptitude. Let´s face it, when was the last time you Googled "All problems solved?" Specialization equals credibility. Credibility equals trust. Trust is the most important element in your relationship with your customers. When you have credibility, your customers trust that what you have to say is valuable to them; practically, emotionally and financially.
You have used positive language
I saw this on a website the other day: "We never leave you disappointed." It reminded me of the old "I will give you a hundred dollars if you DON'T think of a blue monkey" bit. The mind creates the image it is given, and so often web copy focuses on the PROBLEM our clients have, rather than the SOLUTION we offer.
Example: "I help people to stop forgetting things." Not only is that a pretty small target market, it focuses on the problem without offering a solution.
Now try "I help people improve their power of recall." Suddenly you have a proactive and strong image of what you do. You have also expanded your market without losing focus on your niche. Translate that same principle to your web copy and you will establish a positive frame of mind in your readers. They may not buy anything from you, but you will make them more receptive to establishing a relationship. At the very least you might make someone smile. Instead of "We never leave you disappointed," try "We always leave you happy!"
