For the writers of this new IPR paper, studying the impact of earned media on advertising effectiveness started many years ago. Anecdotal studies suggested PR had far more power to affect advertising success than was generally believed. Thus, having the chance to formally test the concept with firms as prestigious as AT&T and Hotels.com has been a great opportunity. For more about Integrated Marketing and Advertising, see our resources page here.
During the Literature Review for this paper, researchers found some 25 studies already in existence addressing the effectiveness of Paid, Owned and Earned media on one another. However, none of these studies tested the impact of earned media vs. paid in real-life testing environments. ABX, a global advertising research firm with testing norms on 150,000 ads, examined this environment in a new study.
In summary, this study collected Net Positive Audience Impressions from Hotels.com and AT&T over a nine-month period. During the same time, ABX ran test-and-repeat surveys on select Hotels.com and AT&T advertising creative. The objective was to compare changes in the creative test scores against the audience impressions to see if there was a relationship. Did the news coverage push the ad scores up, down, or not at all? Results are shared within five key takeaways below:
As initially believed, earned media appears to impact advertising effectiveness, where the largest marketing investments are allocated.
- The anecdotal restaurant case study below illustrates how a news crisis can devastate ad effectiveness. Five ads (blue bars) were tested before a crisis and scored very high. Then news broke regarding the misbehavior of a company spokesperson. The same ads were re-tested (red bars) and ad effectiveness dropped about a third. This meant whatever media had been purchased for those ads would deliver much lower outcomes than expected. An ABX Effectiveness Index score of “100” is considered “Average.”
- The second chart is from Hotels.com and shows how positive media coverage can help drive a higher advertising score. The ad that was measured, “Captain Obvious Runs for President,” was supported by PR campaigns, which likely helped drive the creative score from an ABX Index of 85 to 91, which met a +/- 95% Level of Confidence. Correlations between PR and ad scores were r=.86.
Paid- and Non-paid teams work as an integrated marketing communications team and agree on a testing method.
- PR management should cultivate relationships with advertising staff to integrate their efforts AND to measure results. As mentioned above, Hotels.com actively publicized the Captain Obvious advertising campaign and supplied Net Positive Impressions for the PR side of the equation. What PR needs from Advertising is the chance to have a big-dollar ad measured by the company’s copy testing firm both BEFORE and AFTER the PR campaign. Then, if the ad creative scores change, the PR campaign can likely take credit. (The Ad Report below is a good example of what a copy test looks like).
For clear results, keep your studies small and focused
- The Hotels.com study provided only 109 Key Media clips over the 9-month period, which were very focused. The AT&T study, by contrast, provided 31,976 clips on all relevant topics. For AT&T, three ads were measured each month and correlations between Net Positive Impressions and the ABX Ad Index overall were very high at r=.93 to .97. However, the scores themselves didn’t change enough over time to show any real PR impact. Researchers should have limited the clips to demographically- or campaign-focused subsets to have a greater chance to see PR impact advertising scores.
Do the Math. The impact of earned media, positive or negative, can be huge. Here’s a way to think about monetizing an ad improved by PR:
- A TV spot receives an ABX Index score of 100 (Average).
- The TV spot had a $2 million ad buy against it and should deliver results commensurate.
- A positive PR campaign runs and increases the ABX Index by 20%, up to 120
- Now, the $2 million ad buy delivers an extra $400,000-worth of business outcomes, thanks to PR.
- The Literature Review for this study yielded incredible experimental studies and papers on how PR and advertising work together. For instance, one study found that negative news followed by corporate image ads have a worse effect than running the corporate image ads before the negative news hits. (Pashupati, Arpan & Nikolaev, 2002). The paper provides citations of extremely important work from both PR and Advertising scholars. For more on Integrated Media Across All Media Types, see here.
The researchers are now open to new participants for next phases of the study. Goals include:
- Is there a threshold that earned media must attain to see a noticeable impact on paid media?
- Is this effect consistent across industries?
- Is this effect consistent across media types?
