Introduction to Search Engines
Google is the leading search engine, holding about 90% of the global search market. But is it because Google is better, or are there other factors at play? A recent study published by the National Bureau of Economic Research aimed to find out. The researchers tested 2,354 desktop internet users to understand why Google dominates the search market.
Google’s Market Power: More Than Just Quality
The study looked at several possible reasons for Google’s dominance, including better quality, wrong ideas about competitors, default browser settings, the hassle of switching, users not paying attention, and data advantages. While many think Google wins purely on quality, the research shows it’s not that simple. The researchers challenge these claims with their findings, stating that Google maintains its success is driven by its high quality and that competition is "only a click away" given the ease of switching.
The "Try Before You Buy" Effect
One key finding stands out: after being paid to use Bing for two weeks, one-third of Google users continued to use Bing even after the payments stopped. The researchers found that 64 percent of participants who kept using Bing said it was better than they expected, and 59 percent said they got used to it. This suggests people avoid Bing not because it’s worse, but because they haven’t given it a fair shot. The study further explains that exposure to Bing increased users’ self-reported perceptions of its quality by 0.6 standard deviations, representing a third of the initial gap between Google and Bing.
Challenging Common Beliefs
When Google users were asked to choose their search engine, making switching simple, Bing’s share grew by only 1.1 percentage points. This suggests that default settings affect market share mainly by preventing users from trying alternatives. The authors state that their results suggest perceptions about Bing improved after exposure, and some participants may continue to prefer Google but not switch back due to persistent inattention. Analysis of Bing’s search data showed that even if Microsoft had access to Google’s search data, it wouldn’t dramatically improve results.
How They Did the Research
Unlike studies that ask people questions, this one used a browser extension to track real search behavior over time. The researchers split users into groups: a control group that changed nothing, an "active choice" group that picked their preferred search engine, a "default change" group paid to switch to Bing for two days, and a "switch bonus" group paid to use Bing for two weeks. They also measured how users’ opinions changed after trying different search engines. Many users rated Bing higher after using it.
What This Means
These findings suggest Google’s advantage comes from exposure, not just from being technically superior. Current legal cases against Google may not have a significant impact unless they encourage more people to try alternatives. The researchers conclude that regulators and antitrust authorities can increase market efficiency by considering search engines as experience goods and designing remedies that induce learning.
Conclusion
The study’s results have significant implications for the search engine market. They suggest that Google’s position may not be as secure as many think, although competitors still face the challenge of persuading users to give them a try. As Google faces legal challenges in both the US and the EU, courts are considering ways to increase competition in the search market. For search marketers, the study suggests that encouraging users to try alternative search engines could be a key factor in increasing market share. Ultimately, the study highlights the importance of exposure and experience in shaping users’ perceptions of search engines.
