I have very few impressions and I have a few clicks today. My ratio is kinda high. I average about one or two clicks a day but this is strange. Should I e-mail G?
Low traffic sites that get a few clicks generally yield a high CTR. No reason to contact Google because this is completely normal.
Yes. Email them. You should also email them if you get the hiccups. And when you feel numbness in your legs. Heck, I email them when I'm hungry. You know, just to be safe.
