Hey, I am thinking about contacting other websites in my niche and offering them to exchange links, but when I open the "link exchange" form in their website and they ask to show where I am linking to them in my web. And I don`t know if it is a good idea to link to them first and then contact them and ask to link back cause it may affect my rankings. What do you guys think? Also some of the sites have copyrights from 2008... so it may take forever to hear from them. Thanks for your thoughts.
