---- More competition for your display ad inventory

it's known that ctr and bid are taken into account, what issue is there about this? Ads set up so people don't click on them will end up costing much more for advertisers, yes?
CTR from what time period?
What time period would be the most accurate for a baseline, year over year, month over month, week to week? You know, we all know, that last years CTR may be significantly different from this year, as well as month to month. What is a fair and accurate baseline for clicks or even earnings to use as a starting point for calculating a competitive rate for a CPM ad?
CTR from which ads? Some are clicked more, some are more relevant. What about diet ads from last month, year, week?
Coach, those are just some of the issues about CTR and Bids. Yes, CTR and bids are taken into account, but which ones? That's a rhetorical question, it would be unreasonable to expect Google to state explicitly what data points they are using. I'm just pointing out where the issue becomes opaque, which is giving rise to questions in some minds as to Google's ability make this calculation. Some webmasters are skeptical.
