In the new Keyword bid idea panel I recently got some advice that has me scratching my head.
If I increase my bid I get more impressions.
My current bid was attracting 1000 impressions (for example).
The top suggested bid was 400% my current bid with a corresponding 20% increase in impressions.
Currently my CTR is 10% (for example) - by bidding 4 times as much the KBI is suggesting I can get 15% CTR for example.
How can my CTR improve if I pay more per click? What levers are being pulled to suggest this outcome?
