In March, clicks mirrored impressions with mobile click share rising to 9.8% of all paid search clicks (desktop + mobile). We’re predicting that mobile click share will surpass 10% in April. Q1 YoY growth for mobile clicks outpaced impressions, increasing by 230%. Over the same period, clicks from computers grew moderately (13.7%):
