AdWords Automated Bidding Strategies
Some of these work very well given enough conversions data, but beware of not setting a max cpc bid limit and beware of messages telling you that spend is being massively limited by your max bid limit e.g.
98% of spend limited! It’s telling me, explicitly, that I could be getting a huge amount of extra traffic, an, implicitly, that I wouldn’t be paying any extra for conversions.
However, the bid strategy above is using a Max CPC that is *the same* as the target CPA! So unless the conversion rate gets better than 100% ! I’ll be leaving the max bid limits where they are thanks very much…
