Search Spend Grows as Instagram Thrives: Our Q3 2018 Digital Benchmark Report

October 24, 2018

In Q3 2018, paid search saw healthy 13% year-over-year growth—driven almost equally by increased click volume and rising CPCs—while Shopping ad budget share reached an all-time high of 36%. Also, Instagram ads gained ground, grabbing 15% of total Facebook spend, with Facebook’s news feed accounting for over 80%.

We share these insights and more in our Q3 2018 Digital Advertising Benchmark Report. Our interactive format reveals the latest cross-channel advertising trends by region, industry, and publisher.



Other highlights for Q3 2018 include:

  • Instagram Gaining Momentum: Instagram Stories was the most popular ad format, accounting for 25% of all ads on the photo and video-sharing platform. Due to its rich ad format, deeper level of user engagement, and less crowded feed environment, advertisers are willing to pay a substantial premium for Instagram ad placements over Facebook. This includes a $0.82 CPC on Instagram, four times higher than the $0.19 CPC on Facebook.
  • Global Search Spend Barrels Ahead: In addition to 13% YoY growth in search spend, the average global CPC increased from $0.80 in Q3 2017 to $0.83 in Q3 2018.
  • European Paid Search Slows Down: Anomalous to increased global search spend, eurozone growth was relatively meager at 5.7% YoY in Q3 2018. Europe also saw lower CPCs than the global average, with a $0.44 CPC in Q3 2018 compared to the global average of $0.83. With the General Data Protection Regulation (GDPR) wrapping up its first full quarter, lingering privacy concerns may be taking a toll on the European search advertising market.
  • Shopping Ads Gain Share: Shopping ads captured 37% of the average retailer’s search spend, eclipsing the 36% observed in Q3 2017. The expectation is that dynamic ads will continue to take share from traditional text ads in Shopping and other verticals.
