When clicks trigger rules you can chose to additionally tag them based on the clicking pattern and the type impact to your advertising efforts and business.
You will find the following click tags available in rules and shown in click reports:
Clicks can be tagged as FRAUDULENT when clicking patterns for individual or repeated clicks indicate click fraud.
Clicks can be tagged as ABUSIVE when an individual source of clicks or a group of sources fit into abusive clicking patterns (competitors!).
DISRUPTIVE clicks hurt the business or have major impact to advertising efforts.
Clicks can be tagged as UNWANTED for various reasons such as clicks from non-converting lookie loos (click around, never spend money).
Clicks are tagged as CONVERTED when ClickGUARD records a conversion event.
