Example: you've got a mold problem you want to fix..then an ad that's exactly the same but has Mold-Solutions-Now.com as a Display URL will pull more then the exact same text but with the url "Black-Mold.com" and the mold solutions url has been proven to get 1% better CTR..and you know what that means for keywords that have a 1000+ searches per day..
BUT...I've heard somewhere that Google only allows EXISTING urls to be used. So when you use one that doesn't exist, it violates their TOS. My question is...is that true?
Because what if I want to split test Display Urls but a display url that does not exist in real life proves to be better then the url I currently own..does that mean that I have to buy that domain or subdomain just so I can DO the test without violating the terms of service?
It doesn't make sense to me..
In other words..how do you split test display urls without dropping your relevancy score or so to speak? Does my question make sense there :p
