  5. Making Use of Additional Time

  6. Time + Search Understand how time influences the search experience

  7. Time in Search: Micro Scale • Impact of sub-second changes in response time • Study using large-scale query log analysis • Natural variation exists within a single query • Measure interaction as f(response time) • Time to click • Abandonment rate

  8. Small Increases  Big Changes

  9. Impact of Sub-Second Changes • Imperceptible changes impact behavior • Impact of slower page load time • Slower time to click • Increased abandonment • Some queries more sensitive to time than others • Time impacts navigational queries > informational • Informational queries less impacted by very slow results

  10. Time in Search: Macro Scale • Impact of longer changes in response time • Two user surveys with 1476 participants in total • Detailed survey with 141 MSFT employees • Online survey with 1335 people • Asked about the participant’s last search • Willingness to wait for results as f(response time)

  11. Last Search Took Minutes or Hours

  12. Time Constraints in Search • Reported spending more time on some searches • Important tasks • Tasks with a deadline • Tasks with bad search results • Time constraints • 34% of tasks needed results urgently • 39% of tasks needed results by a deadline • 27% of tasks needed results whenever

  13. Willingness to Wait • Time willing to wait < actual time spent searching • Participants do not trust the search engine • 28% people said they want “fast results always” • For important tasks • Spent more time searching than less important • Willing to wait less than less important

  14. Willing to Wait for Quality Results

  15. Impact of Longer Intervals of Time • People do not want to wait, but… • Report spending a lot of time on important tasks • 90% of the important tasks took more than 1 minute • 23% of respondents found their results unacceptable • Are willing wait in some cases • When the results obtained were poor • When a perfect answer is sought
