Search index

Based on Tongsou search volume, a weighted daily figure (not raw counts) for each term, for comparing popularity and how it changes.

Overall combines desktop and mobile; mobile counts phones and tablets only.

Year over year compares with the same period last year; period over period compares with the period just before (e.g. the last 30 days vs the 30 days before that).
