You may not want to look like you’re advertising, but you clearly are. 🙂
My feedback:
1. You need a better intro video. No voice over is just creepy.
2. At a quick look I can’t see why as someone who has paid for PluralEyes I would buy this. Is there any reason? For people without PluralEyes the price is the biggest selling point, so that should be the first thing people see when they visit your site.
3. You can buy a great wordpress theme for $50. Your site currently doesn’t inspire consumer confidence.
Other marketing advise will not be free. 🙂
