Scroll down to the Keywords section. This is a text field and will allow you to add a maximum 1500 characters. Please separate keywords by commas, and use all the space you have. Keywords will help your store get found online so add in anything that you think people would type into a search engine to find you and/or the products you sell.
If you want french traffic as well then add in your keywords in french in that field.
