Google’s Jon Diorio announced on Google+ that some AdWords data is now being updated more frequently. Diorio said, “I’m excited to announce some improvements in data freshness. Now you will see more frequent updates to search term, geographic performance and automatic placement stats. Try checking your search terms for yesterday or today.”
