Black Hat Pay Per Click Methods
Rob Kerry has written a very interesting article on Search Engine Watch about playing dirty with PPC. While these techniques aren’t something I would recommend using myself, it’s very useful to be aware of black hat pay-per-click methods as it’s possible your competitors could be applying them.
In the article Rob discusses how you can duplicate a competitors ad text to replace their ad by outbidding them, publish non-compliant ads before they’re manually reviewed, use multiple accounts to list several ads for the same search and cloaking competitors IP addresses.
