I hosted my site at hostmonster.com, and got $50 google adwords credit each month. However, when I input the promotional code in my billing preference, it said the promotional code not work for Chinese advertisers. My adwords billing and targeted country both are U.S., and my site is also hosted in U.S. How can I get this problem? BTW, I based in China, and applied the adwords account here, and the hostmonster account's billing address is also from China. Can anybody tell me how to redeem this $50 adwords credit?
If you live in China and it says that promotional codes doesn't work there, then you can't do anything...
If your addresses are down as China, then the promotional codes will not work. Maybe you can try signing up a different adwords account, with a US address?
