2 months ago I purchased a domain with Google is also included like googlexxxxxx.com. From then I used AdWords to generate traffic to my site. Everything worked fine till 2 weeks back. All of sudden, the ads are stopped and saying that quality score is low. Although I have very relevant keywords in my campaigns and bidding for competitive price also not working. It is never happened like this before to my 4 sites. Is it just because, in my domain 'Google' is included, the Google stopped showing ads / banned. Can Google do this? Google has ever given any statement that a domain can not contain 'Google' to show ads in AdWords system.
For your safety, you'd better not use the domain which contail the word 'google, adwords,adsense, gmail' inside.
You can't even generate a campaign with Google in the text of the ad (I tried) let alone create a campaign for a website with "google" in it.
