Hi Laura,
The concept and design of your webpage is very nice! And I think the product looks extremely valuable to your customers. The fact that you have something unique to offer puts you in a fantastic position, because there's less competition...but, as you said, the flipside is that sometimes it makes it tough to explain to people what they're getting! :)
Perhaps if you think about some of the following questions it will help focus your thoughts a little.
1)--WHO. Who's your target prospect? At what stage are they in their web development? Are they small companies? Solopreneuers? Are they in large or small niches? You've done a good job pinpointing some of their primary frustrations...but take some time to think even more deeply about that, if possible. Why are they online in the first place and what are they trying to get out of it? Then talk to that person directly...call them by name..."Attention: Frustrated Solopreneurs Just Starting to Tackle the Online World," for example...
2)--"What's in it for Me?" The three bullet points on your site clearly define WHAT you're offering, but try to articulate the benefits of your service to your customers by answering their unspoken question: "What's in it for me?"
To do that, take a feature of your service--i.e. "A categorized, complete listing of every web mention for up to three search terms organized by topic"--and ask yourself, "Why would my prospect want this?" Then, when you have an answer to that, ask it again. And so on and so on until you can't think of anything more. You want to get both surface and core benefits that tap your prospects' emotional needs as well as their professional needs.
3)--Finally, after you've thought about the questions above, try putting together a headline that really spells out one of those core benefits.
Hopefully these suggestions make sense. If you have any questions or anything, don't hesitate to ask. Good luck!!
