The thing to remember here is to use size, loss, and review to avoid losing lots of money and getting swept away in the excitement of Adwords.

1. Size. This is true with almost any campaign via any platform: start small! Develop a reasonable budget for using Adsense and start off small. You can always increase it, but it’s hard to get back money you shouldn’t have used in the first place. Starting small allows you the time to find out what works, without the pressure of having to get money back in sales to offset the big ad budget.

2. Loss. This goes along with budget. Within that budget, know what you can afford to lose. It’s entirely possible that your first attempt (or first few attempts) using Adwords fails. As a result, if you put $1000 toward using Adwords but you really could only afford to lose about $300, you’re up a creek without a paddle.

Instead, invest, say, $200 first and wait to see if it works; you can then put another $300 to increase the budget.

3. Review. This is a game of test and check. By testing a variety of keywords, you can review their results, make adjustments, and keep going. Some of your choices will work, and some won’t. By continually testing and reviewing your strategies, you will, over time, develop a few solid strategies that really bring in the numbers – via traffic AND sales.
