In the Properties column of Store Commander, you'll find a panel called SEO.
This is where you can visualize and modify the product SEO information on each of your shops.
Indeed, the panel includes a 'Shop' column that helps you identify the product information on each shop - and any language installed on your store.
Double click to edit and modify the corresponding information.
Don't hesitate to use the filtering tool in the Shop or language columns if need be.
And of course, you can select multiple products to work in bulk even more!
