just out of curiousity, what do you guys use as a reivestment strategy with adwords? I'm curently debating the amount and have concluded that 50%+ for the first 6 months will greatly increase my potential for profits the following 6 months. So on a campaign where my profits are 100% I'll reinvest 50% of the total amount back into it for 6 months straight. I was actually debating doing 100% but I need to pay my bills with something.
