The media and advertising world isn’t just evolving—it’s transforming. Fast. 

Digital is accelerating. AI is disrupting. Audiences are shifting. 
And the rules? They’re being written in real-time.

As technology reshapes how content is created, distributed and consumed—advertisers are navigating a landscape that is more fragmented, competitive and data-driven than ever before. With ad spend growing 3x faster than consumer spending, the rise of Over-The-Top (OTT) platforms, retail media networks and AI powered tools is redefining how brands engage with consumers—and how performance is measured.

At the same time, traditional formats continue to demonstrate resilience. Live events still draw significant audiences, while TV remains a key medium, particularly in regions with limited internet access. Even though print media is on the decline, print books continue to dominate global publishing revenue and even Virtual Reality (VR) is evolving and expanding its relevance beyond gaming into productivity and mixed reality applications.

This dynamic environment presents both opportunities and challenges. Advertisers must make strategic decisions about where to invest, how to optimise and how to ensure brand safety across increasingly complex ecosystems and this requires not only creative execution, but accurate targeting, efficient budget allocation and continuous performance evaluation.

What advertisers must rethink in a multi-platform, AI-driven world

Today’s media environment demands more from advertisers than ever before. With audiences spread across a growing number of platforms—and with each platform offering its own formats, metrics and user behaviours—success depends on the ability to plan and execute with precision.

Digital formats such as display and video continue to grow rapidly. Platforms like TikTok are reshaping how younger consumers engage with content, while retail media and Connected TV (CTV) are offering new ways to reach audiences with measurable, full-funnel impact. 

As these formats evolve, so must the tools and strategies used to manage them. AI is now a core component of campaign strategy. Tools like the Trade Desk KOA enable real-time optimisations—such as adjusting bids, refining targeting and enhancing creative performance. AI-driven tools can streamline campaign execution, but without strategic oversight, they risk misalignment. Advertisers must ensure that automation enhances—not replaces—intentional decision-making.

Navigating this complexity requires more than just tools. It demands strategic clarity and operational discipline. Advertisers should focus on three core areas to ensure campaigns deliver meaningful results: 

 

Are your media choices and messaging aligned with your audience’s behaviours and your business objectives?

 

Are you leveraging real-time insights to guide decisions around creative, targeting and spend in a way that supports campaign goals and improves return on investment (ROI)?

 

Are your AI-driven decisions helping performance while safeguarding your brand from inappropriate placement and reputational risk?

 

The most effective advertisers are those who integrate technology, creativity and strategic thinking—turning complexity into competitive advantage.

Is your paid media driving ROI—or driving off course?

Despite the rapid growth in digital advertising, several challenges continue to hinder optimal ROI:

One of the most common pitfalls in paid media is misaligned audience segmentation. When there is a disconnect between the audience outlined in media plans and the actual targeting settings on platforms, campaigns end up speaking to the wrong people. This misalignment can result in wasted impressions, inefficient spend and missed opportunities to connect with the intended audience. 

Impression wastage on the average campaign can range from 30% to as high as 90%, meaning a significant portion of your media budget could be going towards audiences who are unlikely to convert or engage. That’s not a performance issue—it’s a financial one. 

Precision in targeting is essential. Not just to reach the right demographics, but to ensure that every rand spent is working toward a clearly defined objective. 

 

Even with advanced tools and rich data, many campaigns fall short simply because they aren’t optimised effectively throughout their lifecycle. In many cases, benchmarks are not set optimally, making it easier to hit targets but not driving optimisation of the overall campaign.. This creates a false sense of success while limiting the campaign’s true potential.  

Around 80% of campaigns do not meet the recommended number of weekly optimisations, often due to these low benchmarks. This lack of consistent refinement can severely impact performance. Optimisations should be a proactive, ongoing process. It's not just about tweaking bids or adjusting creatives—it’s about continuously learning from performance data and making strategic improvements. When campaigns are left to run without refinement, advertisers risk plateauing results and missing out on higher ROI.

While AI-driven optimisations are powerful, human oversight remains essential. If there are errors in campaign set up, AI will simply optimise towards misaligned goals—amplifying inefficiencies and increasing media wastage rather than correcting them.

 

In today’s hyper-connected digital landscape, brand safety is no longer optional—it’s essential. Where your ads appear can be just as important as what they say. Misplaced ads not only undercut campaign performance but can also cause lasting damage to brand reputation.

We’ve seen real-world examples where ads for adult-targeted products have appeared on children’s YouTube channels, or where brands have been associated with politically sensitive or violent content. These missteps don’t just waste media spend—they expose brands to significant reputational risk. 

This issue is especially critical in high-spending campaigns, where even a small percentage of budget misallocated to unsafe or fraudulent inventory can have serious consequences. Our experience shows that 2-10% of sampled spend in such campaigns ends up on unsafe or fraudulent placements. While that may seem minor, it only takes one person and one screenshot to trigger a viral backlash and damage brand trust.  

With younger audiences spending more time online and across diverse platforms, advertisers must be more vigilant than ever. In the age of social media, a single poorly placed ad can spark a media frenzy. That’s why ensuring proper targeting parameters and implementing robust brand safety tools is critical. It’s not just about avoiding controversy—it’s about maintaining trust, protecting brand equity, and ensuring every impression counts.

Six questions every advertiser should ask to maximise efficiency

To drive meaningful ROI, advertisers must move beyond surface-level metrics and take a closer look at the mechanisms of their campaign. These six questions offer a practical framework for evaluating performance and identifying areas for improvement:
