Is it better off I start off bidding very aggressively. Higher positions generate higher CTRs. So if I start off with a high bid and achieve a top position, IĄŻll create a history of high CTRs. In time, IĄŻll be able to lower my bid (maximum cost per click) and still achieve high positions and traffic volume. Is that true? I really want to do some research about this kind of bidding strategy, but I am lack of data now and it will be more objective with different data. Could someone share some data with me?I don't need the exact figure of every bid of certain keyword, what I need is just a time series data with how much spent for a day and how many clicks received accordingly during a span of time (a quarter,half year or longer). I will post up the results found from the data if I can get some. Thanks!
For example: If your ad gets 5% CTR in position #2 while other advertisers are getting 10% CTR when they are #2, you will not get a very good QS and you will not see your CPC drop. If your ad gets 5% CTR in position #5 while other ads are getting 2% CTR when they are #5, you will get a great QS and you should see your CPC drop and/or your position rise.
Write great ads that get clicked not just because of their position, but because they are more interesting to your target audience than your competitors' ads. Oh, and choose your target audience carefully.
