Welcome to the Q&A Forum

Thank you for this information. This makes allot of sense. Is there any reason you used the number 11?

Do domains less than 11 years old hold no value no matter what?

Thank you for this answer! Very well said!

I understand that keywords and adgroups within a campaign can affect the performance of other keywords within that parent campaign.

I was interested to understand whether campaigns in my account can affect one another.

I have an adwords account with around 30 campaigns. Some are heavy hitters and others get minimal to 0 traffic. Will these low quality campaigns drive up the costs of my high end campaigns?

Is there any value to buying a domain for its PR or age? Or is it no better than a brand new unregistered domain name?

On the flip side, is there any potential danger of buying domains with PR and age?
