I am looking to grow my business, which is completely legit, but VERY competitive. It involves services for companies and I get a decent amount of clicks using AdWords, but for every $100 in ads I only make $20 because it is SOOOO competitive and the PPC is $5. I purchased adWords vouchers and want to make sure they don't catch on as I am always advertising the same website...any ideas or suggestions to make sure i can keep using vouchers and stay competitive with the other large companies I compete with? - i use a different IP each time to register a new account - i use yahoo to create the emails rather than my hosting service - i delete the campaigns and ads and even cancel the account to make sure there are no trails - i use private browsing via firefox so cookies and history are always clear i have only done this with three accounts and going to stop once i can build my income level to be stationary with new clients. thanks in advance!
