Bethany Bey tells us about a PPC Hero survey asking for feedback on AdWords bidding options. The site asked readers to name the Ad Words bidding options used. More than 100 people responded. It turns out that 86% use manual bidding options; 37.6%, automatic bidding for clicks, and 33.3%, enhanced cost per click. The survey also points to percentages for Maximum CPA, Target CPA, and CPM focused on impressions. It also provides feedback and percentages on bidding options where marketers have seen the most success.
