Ironically, this site says "You have only 30 secs" to catch people's attention, but fails to do it itself. Yes, they have a video explaining what they do, but just getting out my headphones so I can watch it would take about 30 seconds. And I don't know why I would want to.

If you want to catch my attention in 30 seconds, your web site needs a sentence like "we provide <insert service here>" at the very top.
