Hi,

People above me already gave u lot of good suggestions, but i think instead of seo you can target pinterest to grow your brand and get some really interested viewers. Your site looks good and images r really nice, and pinterest is full of female users who r interested in cooking and fashion so it will be ideal place for your business to grow. just ya thought, if ur doing it already then good work. cheers
