Brands will spend almost $250B on digital advertising in 2018. Here’s where that money goes.
Search vs. Display
Search advertising (those paid listings at the top of search engine results pages) continues to absorb an enormous amount of ad spend. Magna Global pegs total global 2018 digital ad spend at $237B, with $113B of that spend allocated to paid search.
Everything else, in Jounce’s terminology, is display. That includes banner ads, video spots, and native formats. It includes ads served on mobile phones, desktop computers, and connected TVs. And it includes ads transacted on the open web as well as ads transacted in closed ecosystems like Facebook. And all of that together is now bigger than search -- $124B in 2018.
Unlike search, where advertising is concentrated with a small number of scaled search engines, display ad spend is extraordinarily fragmented. And we’ve never seen anyone add up the spending power of those fragmented buying platforms to square with the total market size. So we gave it a shot. Here’s our picture (drawn to scale) of the display ad spend landscape:
Sizing The Walled Gardens
First, the walled gardens. Six closed ad platforms that control nearly 63% of the display category. These auction-based environments enable rich targeting and differentiated ad units, but they also impose frustrating restrictions on data portability and measurement.
Facebook: Facebook will generate $57.5B of ad revenue this year, and nearly all of that will come from the Facebook app and the Instagram app. We peg this combined revenue at $53.5B. (The rest comes from Facebook Audience Network, which we discuss below.) [UPDATE: We revised down our 2018 forecast for Facebook in this follow-up post.]
YouTube: Google’s big bet on video advertising, by our estimation, will generate $15.0B of ad revenue in 2018.
Amazon: Amazon’s on-site advertising platform is in hyper-growth mode, and we forecast it will generate $4.7B of 2018 revenue.
Twitter: Bouncing back from its recent slump, we estimate Twitter will capture $2.5B of ad spend this year.
Snapchat: Showing modest growth from 2017, we put Snapchat’s 2018 ad revenue at $1.0B.
Pinterest: Starting from a smaller 2017 number, we forecast Pinterest will match Snapchat’s $1.0B of 2018 ad revenue.
Sizing The Open Internet
The remaining 37% of display ad spend is distributed across 10,000 media companies -- some big, some small -- who conform to industry standards for ad targeting and ad measurement. These open internet media companies make their inventory available to buyers through reservations (book an insertion order with the publisher) and through programmatic auctions (bid for each available impression). The advent of header bidding means that publishers often check demand from both reserved campaigns and multiple bidding systems for each available ad impression. Here are the largest of those bidding systems:
Google AdWords (soon to be rebranded Google Ads): AdWords is the buying platform for the Google Display Network, and we estimate it will capture $14.9B of 2018 ad spend.
DoubleClick Bid Manager (soon to be rebranded Display and Video 360): The enterprise version of AdWords, DBM will manage $2.7B of ad spend in 2018.
Oath: Although a slow grower, Oath’s portfolio of programmatic buying tools is still massive. We peg its combined spending power at $5.6B in 2018. [UPDATE: We revised down our 2018 forecast for Oath in this follow-up post.]
Facebook Audience Network: While small in comparison to owned-and-operated ad spend, Facebook’s ad network is an open internet power player. We estimate it will manage $4.0B of 2018 ad spend.
Criteo: The retargeting leader, Criteo’s performance-based DSP will generate $3.3B of 2018 ad revenue. [UPDATE: We revised down our 2018 forecast for Criteo in this follow-up post.]
The Trade Desk: The independent DSP continues to beat public market expectations, and we forecast its 2018 ad spend at $2.0B.
Amazon Advertising Platform: Beyond the walls of its owned and operated inventory, Amazon is emerging as a major DSP force. We estimate AAP will capture $1.2B of ad budgets in 2018.
MediaMath: The leader among the privately-held DSPs, we estimate MediaMath will manage $1.0B of ad spend in 2018.
AppNexus: While primarily focused on its sell-side business, the AppNexus DSP is still a major source of ad spend. Under current course and speed (and assuming no major repositioning under the new AT&T ad division), we expect the AppNexus DSP will manage $700M of ad spend in 2018.
The last $11B of open internet ad spend comes from a combination of reserved campaigns and the long tail of DSPs and ad networks. We see both of these categories under pressure as the combination of header bidding and scaled bidding platforms generates rapid yield improvement for open internet publishers. [UPDATE: We revised up our 2018 forecast for reservations and other programmatic buying platforms in this follow-up post.]
Spend Consolidation
Our math suggests three major shifts in display ad spend.
First, we think reservations are collapsing by 40% year over year. This of course isn’t true for every publisher. (Claritin will continue to reserve the allergies page on WebMD.) But many publishers are seeing programmatic become their dominant revenue stream.
Second, the walled gardens are capturing the overwhelming majority of ad spend growth. Display advertising will grow by $20B in 2018, and nearly 100% of that growth will be captured by the six walled gardens. Open internet ad buying platforms are operating in a net-zero share shift environment.
Third, we think open internet programmatic ad spend is rapidly concentrating among a short list of powerful ad networks and DSPs. Said differently, we think the long tail of subscale buying platforms will see significant contraction in 2018. Some will go out of business, and others will shift their business models to become value added resellers of other DSP technology.
