The service itself seems valuable. There are probably lots of people who has set up Google Analytics for their website but are not using it to guide business decisions. I can imagine myself using it - if I had a website for which it would make sense.
Some feedback on the landing page:
Be more concise or at least get to the point faster. If I understand it correctly, your value proposition for the customer is something along the lines of “get a someone to configure my web analytics tools, interpret the data and present it in a clear manner so that I can focus on making business decisions”. That should be immediately obvious from the landing page.
Seen in that light, I’m not sure if your example makes any sense. If I don’t already use my analytics tool, I don’t care about “odd quirks” in the data.
Better examples would probably be directly tied to business value (conversions, sales etc).
