The screenshot above indicates that both Groupon and Living Social are targeting the Detroit market where I live. Looks like Groupon prefers the terms “Detroit Coupons” and that Living Social prefers “Detroit Deals.” It is unclear what keywords Groupon is using. Perhaps their AdWords budget for the day was expended and not reset for the new day. Seems odd that they did not come up in any of the searches. Living Social came up as the top ad or the only ad on four variations of those search terms.
Example Google searches for those terms
