Google page rank is very important!
You did a nice/excellent job for your SEO but you should be more careful about same thing. You are just on the half of way.
1. You have meta keywords but there is non in: text; url; alt... heading; italic; etc etc. And Google hates that. That's a pure, 100% valid Black Hat.
2. Add this line in the index page: <meta name="robots" content="index, follow" />. (I saw you validated etc etc). Make robots.txt and name there what you want. It is used mostly for "what Not to follow"...
3. Urls like you have are bad urls: yourdomain.com/Shop/Shop.php
Dont Ever put in your urls same word several times.
4.5.6... No RSS; No valid design (w3c)... Links should be on the websites with same topics...
Btw: Sorry for the late answer, i just registered today.
