Google Says Search Ads Boost Brand Awareness

Google conducted a joint test with Levi's and found that paid search ads raised consumer awareness of the Levi's brand, regardless of whether or not they were clicked. In the test, 53% of "in-market" consumers named Levi's when asked which brand of jeans came to mind when a Levi's search ad was in the top sponsored position.

That seems pretty likely anyway, but only 30% named Levi's when there was no Levi's search ad on the page. You can't deny that 23% is a pretty significant increase.

"Better yet, when Levi's 'non-customers' (people who hadn't bought Levi's jeans in the past 6 months) were asked the same question, 45% named Levi's when the ad was in the top sponsored position, versus 23% who named Levi's when there was no ad in the search results,"
