With the evolution of the semantic web, Google becomes an answer engine and gives answers to queries before displaying the SERP.
We had a lot of reference pages that lost traffic in this way. Does anyone know a list when and where Google added "answers" in specific niches?
For example:
"Weather in New York" shows the weather forecast directly on Google since 2012 (roughly) while the results for the equal Spanish query "Tiempo en Nueva York" was introduced just a year later.
Another example is in Sport results and schedules:
NFL results were introduced before UEFA-Champions-League and "Ski World Cup" results are still not being shown.
A full list could help webmasters in analyzing external factors.
