While the full report is noteworthy, we’re here to take a closer look at Google’s advertising business. For starters, the Mountain View, California-based company reported that Google’s advertising revenues jumped from $19.14 billion in the second-quarter of 2016 to $22.67 billion in 2017.

Alphabet’s overall advertising revenue rose again because Google continues to see a jump in its aggregate paid clicks, which represent the total number of ads served across Google properties. However, the company’s aggregate cost per click, which is the price advertisers pay every time a user clicks on their online advertisements, keeps falling.

The company’s aggregate paid clicks climbed 52% year-over-year and 12% quarter-over-quarter, which smashed our consensus estimates calling for growth of 38% and 0%, respectively.

Paid clicks on Google properties jumped 61% year-over-year and 15% quarter-over-quarter. The company’s paid clicks on Google Network Members’ properties rose 9 % year-over-year but fell 5% quarter-over-quarter.

Alphabet’s aggregate cost-per-clicks dropped 23% year-over-year and 6% quarter-over-quarter, which both came in weaker than our consensus estimates of 15.8% and 5.6% respective decline.

The company’s cost-per-click metrics on Google properties dipped 26 % year-over-year and 8% quarter-over-quarter. The cost-per-click on Google Network Members’ properties fell 11% year-over-year but actually gained 5% quarter-over-quarter.
