our site all have high PR anf traffic, but i find it is difficult to find need high quality site to excange link.
every week i find 50-60 sites to send link exchange query emails, but only can succeed 5-6 sites. so low sucessful rate. how about you?
I face the same. But it is not surprising for me. I guess you know that links to your page help the listing in search engines? So everyone just try to get a good position and therefore try to get more links to their page. Once you have a great position and a site with good content you dont need to do that as the user set links anyway.
So the only thing you can do is to delete your requests.
For getting links from quality sites you have to provide quality content on that high PR site and you should do conversation with people on quality sites so that you may get quality links from those sites.
