Intro
Google employs a multi-faceted approach to measure the quality of its search results, including surveys, expert evaluations, and user behavior analysis. Elizabeth Tucker, Google's Director of Product Management for Search, detailed these methods in a recent episode of the "Search Off The Record" podcast, offering insights into how Google navigates the complexities of search quality improvement.
How Google Measures Search Quality
Google's strategy for assessing search quality involves several metrics and methods to ensure they are providing relevant, accurate, and trustworthy results.
User Surveys and Human Evaluators
Tucker explained that Google samples queries and has human evaluators assess the results for relevance. These evaluators help Google understand how well the search results meet users' needs.
Behavioral Analysis
Google also analyzes user behavior patterns to determine if users are finding the information they seek. This analysis helps infer the effectiveness of search results based on user interactions.
The Challenge of Measuring Search Quality
Tucker acknowledged the difficulty of measuring search quality, particularly as user behavior evolves with improved search capabilities.
Complex Queries
As search quality improves, users tend to make more complex queries, creating a moving target for Google's search teams. Tucker noted, “The better we’re able to do this, the more interesting and difficult searches people will do.”
Counterintuitive Metrics
Tucker pointed out that some metrics can be misleading in the short term. For example, poor search performance might initially lead to increased search activity as users struggle to find information, but sustained poor performance eventually results in decreased usage.
Quantifying Search Quality
Google relies on a broad set of metrics to gauge search quality, including relevance, accuracy, trustworthiness, and freshness. However, Tucker emphasized that not everything important is measurable, and not all measurable things are important.
Simple vs. Complex Searches
Simple queries, like searching for "Facebook," are relatively easy for search engines to handle. However, more complex or niche searches require rigorous analysis and attention, particularly when it comes to critical information such as health-related queries.
The Human Element
Tucker highlighted the importance of the human element in Google’s approach to search quality. Human evaluators play a crucial role in assessing real-world search results, while engineers and product managers work to refine the algorithms based on this feedback.
Looking Ahead
Google's efforts to improve search quality are ongoing due to the constant evolution of technology and web content. Tucker stated, “If we just stood still, search would get worse.”
Implications for Marketers
Understanding Google's approach to search quality can help marketers align their strategies with Google’s evolving standards.
