I would change the color scheme to something less "Salesy." People need to understand that the internet business models should reflect a research first methodology, sales second, unless your sales are coming from places other than mainly internet sources.
Blues and off-greens do well because they promote trust.
I would also recommend keeping a consistent call to action throughout the entire page. For instance, a minor change you can make is giving the navigation bar a fixed position so it stays with the user everywhere - that is really popular now.
I think it looks real nice. Clean and crisp. Seemed to load fast for me.
Could add more social buttons. I get clicks for stumbleupon, Reddit and Linkedin. You might be missing out.
Just my two cents.
This is generally good advice but I'm conflicted about using social sharing buttons. Although they are good promotional tools, and automated, I think they take away some branding of the site. You know, a "Tier 1" website, if you will, is Google, Facebook, YouTube, etc. They have their own branding and don't need anybody's help for backlinks. They are the standard.
Tier 2 websites would be sites like this with large community engagement. They got big using the system properly.
And Tier 3 or less are a smaller brand altogether again. When you add social buttons you are automatically classifying yourself as a "Tier 2 or less" I hope that makes sense. Of course, this is just fine for most people. But I believe if you really want to be "big" that you should market yourself quietly outside of the web in-front of real people and cold calls. What do you think? Then your brand becomes positioned for "Tier 1" standards.
Maybe this isn't the place to post a message like this. But food for thought nonetheless.
