Comment on Fresh AdSense Ready WordPress Theme by SEO Dave.
I’m not familiar with the Instinct WP ecommerce plugin, so had no idea how it would work with any of my themes. Did a quick test with my latest version of Talian (version 6 in development) and it didn’t look very good.
It seemed to work OK, but would require creating various CSS files to match in with the theme. Going to assume you have to do similar with the majority of themes, so I would suggest looking for themes specifically designed to work with Instinct WP-ecommerce.
Come to think of it, I think I tested Instinct WP-ecommerce out a couple of years ago. Was going to create an SEO version, but got distracted on other things, so didn’t get very far.
