At first I think google disapproved my Ad, so the Ad did not show. Actually, my Ad showed ONLY in Japan. Terrible bug.
I created a new campagin, the same thing happened.
BTW: My competitors Ad with that specific keyword works fine.
The same thing happened to my another old campaign!
Very terrible thing!
Few weeks ago, I created a Ad with 5 chinese keywords. And setup this campaign opened in all countires and languages.
I found that only four keywords work fine, the last keyword never showed to anyone, and the IMP,CLICK,CTR is ZERO.
While visiting www.google.co.jp and searching that keyword, my Ad appearedd! Only showed in Japan with that chinese keyword. Faint!
Then I clicked my Ad. Today I found google has recorded my CLICK, and updated the IMP & CTR.
What terrible thing! Is this a big bug for Chinese Ad?
BTW: Google forbid chinese customers to use chinese phrase "Search Engine" as their keyword and displayed in anywhere of the AD. FUNNY THING! I have ever informed Google about that thing, they COULD NOT resolve this bug within few months, or they never care their chinese customer.
I wish Google pay more attention to chinese! More than 20 millions chinese using Google in China!
I worked for a company who's IP block was owned by a company in Japan - I am in Canada. Whenever I started a google search, I got google Japan :( They claim 99% correct country identification, but there are plenty of companies with blocks owned by others, so I think google's numbers are way exaggerated.
