Google says AdWords' real-time targeting and reporting are ideal for finding an efficient way to reach customers in the economic downturn. The company has detailed six tactics for maximizing your AdWords investment.

1. Focus your ads on low prices and savings.

"Consumers care about prices more than ever, especially on day-to-day purchases," says Google. "When someone searches on a particular product, you know they're interested; by using your ad to tell them that you've got the highest quality and the best price, you're more likely to earn their click."

2. Use value-related keywords.

People are constantly looking for bargains. Google suggests using keywords that cater to this mentality. The company recommends using the AdWords Search-based keyword tool and Search Query Performance report to find higher-performing keywords that people are actually searching.
