I have a store, but i don't know which keywords are the best for my site. General keywords aren't suitable. People, who buy anything, don't use general keywords. If I knew right keywords, I would make more purchases. How could I know right keywords? My site visit people, but they don't buy. I thing that my keywords aren't right. My site don't visit customers. My site visit just visitors. How do you know right keywords? Do you use a program or anything else for this?
