I started adwords last night. The keywords I selected had minimum bid of $0.05-$0.10. This morning they were all $10.00. Now they are $0.40-$0.50. I have not changed anything. What is going on?
Nothing springs to mind. If they had jumped from $0.05 to $10, I could understand it. This would probably be Google reviewing your website and deciding they don't like it. If they had gradually increased from $0.05 to $0.40, I could understand it. This could easily be caused by having a low clickthrough rate. Google would penalise you for having an advert or site that people don't want to visit. But it seems a bit strange that it jumped up, and then settled back down again. Possibly a mistake by Google? Either way, your minimum bid is still very high. What sort of clickthrough rate have you got (excluding the content network) and what position does your advert appear in on average?
Thanks for your reply. Not much clicks and even impression. This site has not much content yet. I am just learning.
