Hi everyone, I'm helping a friend improve the SE ranking of his 2 adult sites (selling adult toys). He never tried to use SEO until now. I've worked for some very competitive keywords before but am NOT sure if the same strategies I know will give us the same success. This is my first time to work on an adult niche. Most desperate SEO specialists would resort to black hat techniques (I guess this works best for adult niche?). I'm not really sure. What strategies will work best for this? How about paid links? At the moment the sites rank for some less competitive keywords. Of course we want to target for the highly competitive ones. Thanks in advance!
