it includes:
1. Categories title - exactly like the category name.
2. Produnt title - exactly like the product name.
3. Changing the continue button which send you back to the http://your-domain.com/index to send you back to http://your-domain.com
this will reduce the duplication of contexts for seo reasons.
4. Removing the www from the domain (a redirect 301 from http://www.your-domain.com to http://your-domain.com ) this will reduce the duplication of contexts for seo reasons.
