Hello,

1. Here is an article that describes how products tabs can be changed https://docs.woocommerce.com/document/editing-product-data-tabs/

2. Try to set it in this format http://www.pinterest.com/etsy

3. You need to update the theme to the latest version and enable SKU search in Theme Settings.

4. Permalinks structure can’t be controlled by our theme. All available options you can find in Settings -> Permalinks.

5. Sorry, but we can’t check this without looking into your website.

6. You can change products order in admin panel -> Products -> Sort products.

7. We suggest you to use some additional plugin for this like Yoast SEO or this one https://wordpress.org/plugins/wpseo-pinterest-rich-pins-for-woocommerce/

Regards
