I think that beyond the technical complications many smaller businesses are being priced out of the market by big brand bidders. These bigger brands are (at least in the UK) finally cottoning on to the benefits that online marketing can provide to their whole business, beyond direct online sales. I wouldn't like to be a small company that depends on PPC these days - I think their positions are going to go down and down as more and more larger organisations jump on the bandwagon and start funding online marketing with massive brand budgets and multichannel targets.
