I exchange links with a links exchange site and I want to know if I should exchange links with site that are not related to mine,
will it help my page ranking or will it hurt?
I have so many sites asking for exchange though most of them I will not exchange with as they are gambling and pharmacy site, but what about the others will it hurt if i exchange links with them can anyone help?
