I like wine and wineries :) by the way.
What`s the call to action do you want when someone hits your home page?
I see your keywords in the meta tag; what`s the aggregate traffic you are currently getting from those keywords you are targeting? Are you happy with that amount of traffic?
Is this an info site or a money-making site?
What ways do you want visitors -- organic search engine traffic, pay per click, banner ads, social media traffic?
You`ll want to take a look at your duplicate content issues.
If you want this site to be a serious lead generation / sales site, let me know, and I can help you work through that.
We work with established small to medium size businesses that are in the position to invest in improving the results of their online presence.
Let me ask you three questions.
1) What is your cost per online visitor?
2) What is your revenue per visitor?
3) What is the lifetime value of your customer?
I will cut to the chase on the SEO/SEM efforts to focus on increasing your bottom line.
