[Paper] Effectiveness of Paid Search Advertising: Experimental Evidence
Title: Effectiveness of Paid Search Advertising: Experimental Evidence
Authors : Daisy Dai, Michael Luca
Abstract: Paid search has become an increasingly common form of advertising, comprising about half of all online advertising expenditures. To shed light on the effectiveness of paid search, we design and analyze a large-scale field experiment on the review platform Yelp.com. The experiment consists of roughly 18,000 restaurants and 24 million advertising exposures – randomly assigning paid search advertising packages to more than 7,000 restaurants for a three-month period, with randomization done at the restaurant level to assess the overall impact of advertisements. We find that advertising increases a restaurant’s Yelp page views by 25% on average. Advertising also increases the number of purchase intentions – including getting directions, browsing the restaurant’s website, and calling the restaurant – by 18%, 9%, and 13% respectively, and raises the number of reviews by 5%, suggesting that advertising also affects the number of restaurant-goers. All advertising effects drop to zero immediately after the advertising period. A back of the envelope calculation suggests that advertising would produce a positive return on average for restaurants in our sample.

The online advertising industry value chain
Via
- The Client demands the Advertising Agency to run an ad campaign.
- The Agency tells its Trading Desk what kind of ad space to buy, according to the Client’s requirements regarding its target consumer.
- The Trading Desk establishes a set of guidelines, and asks a Demand-Side Platform (DSP) to buy ad space according to these guidelines. DSPs are buying specialists, they run intelligent algorithms to pick the cheapest ad space relative to its quality.
- The DSP keeps tracking all the ad spots that come up for sale on Ad Exchanges, establishes the value of every one of them, and bids for the most relevant ones. It uses data from various data providers to come up with its valuations.
- The Ad Exchange is an open platform that enables websites to place their available ad space for anyone to buy in an auction.
- The websites themselves try to attract traffic. They receive traffic naturally, from ingoing links, search engine results, and returning visitors. However, they can also buy traffic from Traffic Brokers (for ex. Taboola and Outbrain, two « content discovery platforms »).
