I wouldn't ask this unless I have found an answer to this problem. I have had Adwords account for over 2 years and recently or actually in last few months, not any campaign of mine are running and I don't know the reason for this. Here are some important things to be considered:
1. I have money in my balance.
2. I have checked all my campaigns keywords, they are all eligible and they also have Quality score at least 5 or over.
3. All my ads are reviewed and approved by Google.
So what is the problem of my account that it doesn't show my ads? These ads are PPC and they are not running on search engines neither in any website. So what could be problem? Anyone can help me? I can't either contact Adwords stuff because there's no contact information of their.
