The reason Groupon was dominating the Google AdWords traffic for the selected San Francisco tour related search queries, is because it was running text ads that mentioned tour discounts it didn’t offer, San Francisco Comprehensive Tours said in its lawsuit. As long as the business that issued a particular voucher has sold enough of them, you can trade in one of those vouchers for a specific product or service at that business. The tour company said in its complaint that, to its knowledge, Groupon only offered a single coupon on its group-discount buying Website that had to do with San Francisco and tours during since September of last year. Groupon is a website that allows you to purchase vouchers for various products and services at discounted prices. At the same time, defendant Groupon’s AdWords link began to appear at or near the top of purchased placement search results for Google searches including the terms “San Francisco Tours,” “Alcatraz Tours,” and “Napa Wine Tours” Beginning in about September of 2010, Plaintiff (San Francisco Comprehensive Tours) observed that the cost of its click-throughs began to skyrocket, and its ranking in the purchased placement area for searches including the terms “San Francisco Tours,” “Alcatraz Tours,” and “Napa Wine Tours” began to decline.
