Don't understand your question. Could you expand a little more, you might get more replys that way. Regards.
I think you mean to say about page relevance. exchanging links from related sites definitely better than non-relevant link exchanges ... !!!
How do you measure relevancy? If the linking page is relevant but the overall domain is not relevant, I donot think it will help much. But than again if the linking page is well optimized with page title, content and the filename containing the keywords, it will help.
I think so,exchanging links from related sites definitely better than non-relevant link exchanges ...
