why 90% new keywords minimum price is >=$0.1?

[peony]

Recently, 90% new keywords I add to my new or old ads have the minimum price >=$0.1. But in the old ads, most of my keywords are only $0.05 and 99% of them get a >=0.5% ctr.
Does it means that google increased the lowest Quality Scores Or just google want more money from advertisers?

The reason seems to be the low CTR history. Judging 0.5% as OK is a big problem.

I know some areas are lower for CTR but 0.5% isn't making google much money at 10c. (that's equivalent to 50c per thousand impressions, not good)

I would be pulling (what's left of) my hair out if I had such a low CTR, 4%+ is the target I aim for. When I start a new campaign Google sees that I have a good history of CTR and it gives me keywords at a price that it thinks is suitable.

As an example, a campaign that I set up on the day of the change (30,000 keywords) I have 22,000 at 5c and 8,700 at 10c, just 300 are asking for more. The CTR is low at 1.8% but growing as the ads climb the positions (currently average 6.0).

If you make google money they will reward you with a better deal. That's what I like about their algo.

I am paying 100% more for the words I used to bid on due to this change. No more nickle clicks in many words are allowed. Not even dime clicks. Some words are so outrageous that they go with no ads at all. I don't blame them (the people in those campaigns). Why bid $1.00 on a word that was .05 previously and maybe you paid .12 cents.

The system has some obvious flaws, and google will see that many words go unadvertised.
