Is the Quality Score keyword metric supported for Yahoo! JAPAN?

The Quality Score column in the Keywords grid shows the current quality score of each keyword. However, because of the limitations of Yahoo! JAPAN API, this value is not available for viewing in the Platform now.

What is the difference between Historical Quality Score vs. Quality Score?

Historical Quality Score is obtained from each night's cost report. It is a snapshot of the keyword quality score for that particular day and may change from day-to-day. Historical Quality Score is also available as a statistical value. It is averaged using impressions as weights, so keywords and dates with higher impressions would contribute more to the final value. Keywords with 0 impressions, or dates with 0 impression would not contribute to final results. Since this column is computed as impression-weighted-average, it is available on the Campaigns, Groups, and Keywords grids.
