Google is set to release its Q2 2014 earnings on Thursday, July 17. In Q1, the company posted that its revenues grew by over 19% year over year. The result failed to enthuse the market which was expecting far better growth in both the top line and the bottom line. The primary reason for this was a decline in cost per click, which has been in a long-term decline for the past two years. However, this decline was offset to some extent by the adoption of its enhanced campaigns program that combines marketing campaigns across mobile desktop and laptops, i.e. across screens of different sizes.
