The two products, Google Analytics and Google AdWords, though separate, are driving toward a similar purpose: Helping Web sites analyze their performance so that better business decisions cna be madeto obtain great performance results. You can use either one of these products alone, or use both at the same time - they will not interfere with each other's tracking.
AdWords Conversion Tracking
In online advertising, a conversion occurs when a click on your ad leads directly to the visitor behavior you deem valuable, such as a purchase, a signup, a page view, or a lead. Google has developed a tool to measure these conversions, and ultimately, help you identify how effective your AdWords ads and keywords are for you.
It works by placing a cookie on a visitor's computer when they click on one of your AdWords ads. Then, if the visitor reaches one of your conversion pages, the cookie is connected to your Web page. When a match is made, Google records a successful conversion. The cookie that Google adds to a visitor's computer when they click on an ad expires after 30 days. This cookie expiration measure, and the fact that Google uses separate servers for conversion tracking from search results, protects the visitor's privacy.
If you'd like to take advantage of more robust Web site analytics, we encourage you to talk to us about a Google Analytics account. In addition to basic conversion tracking, Google Analytics also offers sitewide pageview analysis, advanced goal definition, conversion funnel analysis, and various advanced conversion reports. Just like AdWords conversion tracking, Google Analytics is fully integrated into your AdWords account, allowing you to view your reports and settings from the Analytics tab in AdWords.
