Depends on alot of things. Your marketing ablility, 20 freesites really isnt all that much and it depends who you are submitting those free sites to. Some LL's are good for one type of traffic and others arent so hot. How about a url so we can see what your working with?
P.S.
It took about 6 months for my first sale, but I suck so dont go by what I say
