The debate over whether paid links should count in Google's ranking algorithm has been going strong, sparked most recently by Google's spam-buster Matt Cutts. It's been picked up in most search marketing forums, including SEW's.
Last night, Li Evans posted the collected opinions of 10 search marketers: Andy Beal, Christine Churchill, Anne Kennedy, Debra Mastaler, Greg Meyers, Lee Odden, Chris Sherman, Bill Slawski, Shari Thurow, and Frank Watson. Li asked for opinions on buying links for clients, and on sites that sell links but don't indicate they're paid links. It's an interesting look at the issue from varying perspectives.
