To optimize any ecommerce website we have to focus mainly on page i.e Meta title, descriptions, keywords. Firstly, check the meta tags are present in particular word length as there are fix characters. If it is not present in word limit then try to reduce or increase it accordingly and insert the keyword too. After that we have to check the image is it good or not, if it is good then check its alt tag is present or not. If not then add to it. Make sure size of image is not so large try to compress it with same quality. I hope this information will be helpful for you.
