I thought that. So probably the "legal" way - content, seo, traffic - it's the easier one.
btw: I have another idea. All what you need are different IPs, don't allow cookies and a simple tool/macro that is clicking your google ads. Ever heard of JAP or TOR? This are some kind of free proxy-based anonymization services. They mix up the different IPs of the users. So every time you click on something you have another IP.
JAP -- ANONYMITY & PRIVACY
Tor: anonymity online
