Google PageRank: Not Worth The Worry: "rough reciprocal links and refuse to link to web sites that are lower than PR 5, rethink your strategy. Well-designed, well-ranked sites with informative content are always a safe bet to link out to. That was my basic strategy with a client of mine in the hospitality industry.
They had a PageRank 4 (at the time of writing this article, January 2005) and rank at #6 on Google for 'bed and breakfast directory' (without quotes). The #7 result has a PR 6 and the next three spots in the first page of results are PR 5 web sites, all higher than my client. This example is repeated throughout the Web and proves that preoccupying yourself with PageRank can result in losing sight of more important ranking factors."
