Traffic... Why would I want to give any paid traffic any option to go to a 3rd party website or leave my site for any reason. I still do not agree with outbound links and I have never seen any evidence provided by anyone to support this claim or theory and it also goes again my own testing of outbound links. I understand the idea behind, but adwords does not care about outbound links to 3rd party sites. I have also spoken to google agency reps and other google staff (high up the chain than phone or email reps, closer to designers and decision makers of google) about outbound links and they have also confirmed that this is unnecessary and that google already understands that businesses are not interested in sending paid traffic to any other resources other than there own. But if you can provide sufficient data to support outbound links I would gladly like to see it
