Fair level of page renge that is linking to us

When doing link exchange trade,the PR(page rage) of the linking site is one of the most important we should consider.

when we check the PR of a site asking to link to us .We should check the PR of their home page and the PR of the page that is linking to us.

In same cases,we will notice that some of the links from sites where their home page is PR4 but the page linking to us is PR 0.

If you are focusing on PR, then it needed to comfirm the PR of the page that actually has the link. If the page has a PR0, It's not that "fair"to trade.

However.,If the link is relevant to your site,and has valueble content. It would be well worth to keep the link regardless of the PR it passes to you. Base the value of the link on more than just the PR it supplies to your site.
