OK bear with me - I am hoping this is Adwords paranoia!
I employ ad scheduling, so for instance on monday I bid 10% less and on friday 10% more.
By bidding less on monday your position drops, then your CTR drops which affects your overall quality score and therefore when friday comes around you can't make up the ground.
Has anyone else seen this?
I am beginning to think that I should never bid less, just increase on hot converting days, otherwise you end up with this yoyoing that messes up your quality score and a scheduling system that never actually does as it should.
The CTR is normalized by position. AdWords understands that an ad in position 1 is going to receive (on average) a higher CTR than an ad in position 5. Therefore, they arenít going to penalize the advertisers in position 5 for having a lower click through rate than the advertiser in the first position.
I definitely agree with question number 2. For example, I use Google Analytics to look at conversions on an hourly basis. I found that in one campaign, I had basically only made one conversion in six months between the hours of midnight and 2 AM, so I cut out advertising in those hours.
I would agree with question number 1 as well, that it should always be 3 to 10, but I don't have anything to back that up. I think I just have a very strong personal bias against position preference.
