Nothing in the universe moves faster than the speed of light—but online ad markets come close. Platforms like Google, Meta, and TikTok exist in a constant state of flux, shifting at top speed according to dozens of known and unknown metrics. This makes them marvels of modern technology and explains why they are some of the most profitable companies in history. But it also explains why so many advertisers find keeping up with them to be so frustrating.
The fact is that even the best-staffed, most forward-thinking advertising team can go crazy trying to correctly allocate budgets across half a dozen or more dynamic platforms. Trying to do this manually is like trying to juggle balls that keep magically changing shape in mid-air. Mere humans are simply not equipped to tackle the hyper-automated, AI-augmented marketplaces run by today’s big tech giants.
Enter the world of digital ad platforms. These are services that use the same cutting-edge technology as the tech giants to give advertisers a fighting chance to have their products seen by their target consumers. They maximize return on ad spend (ROAS) while saving advertising teams valuable time. In the struggle to get an edge on competitors—which has never been more fierce than it is today—they’re an invaluable partner.
Manually Allocating Ad Spend Is Impossible
To explain just why digital ad platforms are so valuable, it’s worth digging into some of the factors that make navigating digital ad platforms such a headache for advertisers.
Let’s start with something simple, like when to post a given advertisement. Back in the analog days, the common wisdom was that primetime advertising was most valuable—after all, that’s when the highest number of people were home from work and watching TV. Digital life has exploded that paradigm: people are always on their phones. Some brands might benefit from daytime advertising, some by ads at night, others by an even spread, and still others by an uneven spread. And of course, these facts can change on a daily basis. How is any given advertiser supposed to keep up?
And making things even more complicated is the fact that what works on one platform may not work on another. That applies not just to the right time to post but to a host of complex variables. Obviously, if an ad is taking off on Instagram but struggling to gain traction on TikTok, an advertiser will want to shift resources accordingly. But given the fragmented and siloed nature of these platforms, accomplishing this is easier said than done.
The result is that too many businesses lose hours of each workday rapidly cycling between endless Excel spreadsheets, attempting to make heads or tails of data points that just won’t stay still. For an advertising team willing to work 24/7 every day of the year—without lunch breaks—staying on top of all this information just might be manageable. For the rest of us, though, a different approach is needed.
Boosting ROAS with Digital Ad Platforms
In the digital advertising world, the be-all and end-all metric is ROAS. Manual budget allocation makes optimizing ROAS nearly impossible: there are simply too many factors to stay on top of. Digital ad platforms, by contrast, make it quite easy.
Let’s take a client we were working with in the past year. The ability to allocate appropriate budgets to each campaign and dynamically adjust target ROAS as per budgets can lead to a 10%+ increase in ROAS, including an 18% increase in clicks, while reducing ad spend. By using a digital advertising platform, a client was able to get a more accurate assessment of Google Ads and Microsoft Advertising performance.
Here’s how it works. Advertisers feed their parameters to the platform—what they’d like to spend that month, as well as what they’d like to achieve with that spend. From there, the platform begins the automated bidding process. Instantly, the platform is flooded with data—about optimal ad-posting time, which ads are doing best on which platforms, about which audiences are responding most enthusiastically to which ads (A/B testing enters the picture here as well).
This information is continuously evaluated by the system and used to make real-time decisions that actually optimize ROI. These decisions are undergirded not just by primary data but by deep, AI-augmented analyses of performance patterns over time. In other words, these ad platforms are not merely reactive but predictive.
ROAS is just one of the many objectives. The platform makes testing against different objective optimisations significantly easier, so advertisers can better understand how changes in campaign goals can impact performance.
On the advertiser’s end, these capabilities are at once demystifying and empowering. Instead of rapidly cycling between spreadsheets, advertisers can get an at-a-glance view of cross-platform campaign performance on a unified interface. Instead of groping in the dark to build monthly or quarterly ad budgets out of guesswork, they can undertake long-range planning with the kind of confidence that only AI-enhanced data can provide.
Many digital ad platforms today are designed to handle cross-channel ad budget allocation using both data and AI — making real-time adjustments that human teams simply can’t replicate at scale. Here is what a digital platform can accomplish:
Automated Budget Allocation: Digital platforms automatically adjust daily ad spending based on performance data across all platforms. If Meta underperforms one day and Google is converting better, your budget shifts accordingly — no guesswork, no delays.
Unified Strategy Layer: Find a platform that offers advertisers only one interface to manage, compare, and optimize campaigns across channels. This leads to faster decision-making and holistic budget planning.
Continuous Optimization with AI: The role of AI is paramount. AI doesn’t just track metrics — it learns from performance patterns over time and adjusts spend, bidding, and targeting dynamically.
The known unknowns of missing keywords dramatically illustrate what this technology is really capable of. The fact is that you cannot know the keywords you are not bidding on—which is scary because these keywords might very well be more effective than the ones you are bidding on. Worse yet, your competitors might already be using them. A digital ad platform can correct for these blindspots by automatically finding those keywords—and automatically putting them to your business’s use.
The big social platforms are opaque by design. At the end of the day, a platform like TikTok or Instagram is a black box: only their own marketing teams know precisely how they work. And few if any individual businesses have the resources to manually read the tea leaves scattered Meta, Alphabet, et. al. on an hourly basis. By leveraging the services of a digital ad platform to help allocate digital ad budgets, businesses can radically increase visibility into platform performance—and radically optimize their return on ad spend.
