get it done

i have an amazon affiliate website, i have tried everything,from l;anding page, to funnel, to sign up page,and also google adds,i've posted on all social media,nothin is getting traffic at all, so i thought about the search engine and to me that's the key to getting customers to my site, i have to get the visits in order to get the sales,it's going on 3 months for me without a sale
