Hi we have used a private SEO for some time now and was wondering how or if we can find out if he/she has been using adwords. Using Adwords is outside of our contract and we have been getting conflicting feedback by our customers as to how they have found us on Google. Is there a was to track if our sites have been used in Adwords ?
Thank you

check your Google Analytics account
if traffic there shows , Content or traffic from Content sources
that is not organic
