Google Search changes to meet users' demands and trends. The company added and removed some metrics around various Search criteria, testing each of them to a diverse set of audience before finalizing them.
In 2016, Google made 1,653 new search changes. This was a result from:
- 130,336 Search Quality Tests: Google worked with external Search quality raters to measure the quality of search results on an ongoing basis. The raters assess how well a website gives people what they are looking for.
- 18,015 Side-by-side Experiments: Google improved its algorithms to make Search better. The company used Search Quality Evaluators that worked on two different sets of search results.
- 9,800 Live Traffic Experiments: This was experiments to see how real users interact with a feature, before Google launches it to all users.
1,653 is a big number for Google. But only a small percentage went live. Google mentioned the number when the company announced its Project Owl.
