Does anyone have any stats regarding ad position versus conversion rate or ad position versus profit?
Everyone knows the formula AD RANK = CPC BID x QUALITY SCORE.
So quality score is mainly based on CTR and CTR is mainly based on ad position. Therefore those at the top can pay less per click than lower positions.
There is no doubt that conversion rates are much higher if your ad position is higher. But does anyone have a formula for ad position versus conversion rate or ad position versus profit?
I have run hugely profitable campaigns by bidding high to obtain a high ad rank which gave me the high conversion rates and relatively low average CPC but I haven't got a formula, only gut instinct.
