Hi, does anyone have any opinion on the best policy for exchanging links? We've historically checked that the domain to which we link has a backlink located on the same domain. The idea was that we'd avoid the risk of being caught in a Google clampdown on reciprocal link "directories" (?). So we've been excluding those... in spite of the fact that they often have pretty good PR. Our policy has been: backlink from the same domain as we link to. Wise or should we reconsider?
