Fill rate dropped and revenue went with it
Things started fine but over the last quarter my fill rate on the widget tanked, especially for non-US visitors. A big chunk of my audience is from India and SEA and the eCPM there is almost nothing, so the unfilled impressions just sit there empty. Disappointing because the US numbers were genuinely good.
Strong on tier-1 US traffic
Poor fill and eCPM for non-US / tier-2 traffic
