My thoughts exactly. There's so much competition for KW's that it's quite costly to get your ads near the top for Adwords. And you can't do it cheaply because your Adwords "Quality Score" suffers unless you're receiving some serious click-throughs (which don't occur until your bids are high!).Using Adwords without emptying your wallet can be quite a task. Using the content network and search partners will empty it quickly with little to no ROI.
