In addition to helping you find keywords you should be bidding on, thorough keyword research can also help you identify negative keywords – search terms that you should exclude from your campaigns. Negative keywords aren’t terms with negative connotations, but rather irrelevant terms that are highly unlikely to result in conversions. For example, if you sell ice cream, you might want to exclude the keyword “ice cream recipes”, as users searching for ice cream recipes are unlikely to be in the market for your product.
In addition to measuring your website traffic, you need to track your conversion rates. For example, if, as a result of your search engine marketing efforts, your traffic doubles from 250 to 500 visitors per month, how many new customers did you acquire from the additional 250 visitors to your site? Do you now have twice as many customers as you did before? If you picked up 5 customers your conversion rate would be 2 percent of the new traffic (5 divided by 250) and 1 percent (5 of 500) overall.
