Very functional. Good tips. I think the "instant improvement" button should be renamed. I was looking for a "submit" button or a "show suggestions" button. Instant improvement almost implies that the changes will be made automatically. Please try to avoid Comic Sans whenever possible. The background distracts from your logo a bit. That area could be simplified. The whole thing is so simple it could look as clean as Google's homepage plus a couple of ads. Overall, it's a neat tool.
