Are paid links evil? That's the wrong question. The right question: Do paid links that pass PageRank violate search engines’ quality guidelines? The answer to that question is yes.
Disclosing payments Washington Post, Dec. 12, 2006: “FTC Moves to Unmask Word-of-Mouth MarketingEndorser Must Disclose Link to Seller” "We wanted to make clear . . . if you're being paid, you should disclose that.“ -- Mary Engle, FTC associate director for advertising practices

Practical considerations • You can buy links within search engine guidelines • AdBrite • Quigo • IndustryBrains • adCenter, YPN • any site that doesn’t pass PageRank in links • Buying paid links that pass PageRank violatesour quality guidelines • Paid PageRank-Passing (PPP) links
