Another observation about the site: it's very Facebook-unfriendly at the moment. Try sharing the URL on Facebook and you'll see that the site lacks any text or images that FB can readily pick up for display and thus only your URL is displayed. This app looks amazing, but that does make it a bit hard to tell people about on Fb.
He's referring to the fact that "click here" tells nothing about the link itself (for SEO purposes).
But in this particular case, it's just added to the text "Try World Lens for FREE", so I don't know what's so wrong about it (or why you get down-voted for just asking that question..)
I immediately sent the link to a dozen people, about half wrote back "How much is it?" and "How do I download it?"
Since QuestVisual.com is clearly going to sweep the entirety of the internets by this time next week a few friendly conversion suggestions:
a) Change your button to "Try Word Lens FREE - Click Here"
b) The logo under your button looks like another button, just get rid of it.
Dropped you an email if you'd like the Conversion Voodoo team to bang out a new page tomorrow AM gratis that's ready for installation by noon PST :).
