How to Lower CPA for Your Programmatic Campaigns

1. Use AI-Powered Bidding and Real-Time Optimization

AI-powered bidding has reshaped programmatic advertising, turning it into a predictive and highly efficient process. By leveraging advanced algorithms, brands can pinpoint high-value opportunities and make smarter use of their budgets. Instead of relying on manual tweaks or basic rules, these algorithms process millions of data points in real time to determine the best possible bid prices.

This technology dives deep into data - evaluating historical trends, live auction details, user behavior, contextual signals, browsing habits, device types, locations, and even the time of day. It uses this information to estimate and assess the clearing price for each impression.

What sets AI bidding apart is its ability to adjust bids dynamically based on the likelihood of conversion. Rather than applying the same bid to every impression, the system prioritizes spending on high-value opportunities while dialing back on less promising ones. This precise targeting helps advertisers get the most out of their campaigns.

The results back up its effectiveness. Google has reported that AI-powered bidding strategies can lower cost-per-acquisition by up to 30%. More than 80% of Google advertisers have adopted automated bidding, taking advantage of its ability to optimize performance at scale. Additionally, advertisers who switch from Target CPA to Target ROAS strategies often see an average of 14% more conversion value while maintaining similar returns on ad spend.

Another key advantage is how AI bidding adapts to the challenges of a cookieless world. By analyzing contextual data and using first-party data responsibly, it enables privacy-compliant targeting. This is becoming increasingly important as traditional targeting methods lose their reliability.

Looking ahead, automated programmatic channels are projected to account for 89.3% of global display ad spend by 2025, with 96.8% of new ad dollars expected to flow into these channels. This surge reflects the growing trust in AI's ability to optimize campaigns in real time, reduce wasted spending, and deliver better outcomes.

2. Spread Budget Across Connected TV, Audio, and Digital Out-of-Home

Relying heavily on a single ad channel can quickly drive up acquisition costs. Why? Because platforms tend to exhaust their most engaged audiences first, leaving you to pay higher prices for less interested prospects. By spreading your budget across Connected TV, audio, and digital out-of-home channels, you can sidestep this issue and reach fresh, high-intent audiences on each platform.

Connected TV is a game-changer for reaching cord-cutters and streaming viewers who aren’t tuning into traditional television anymore. These audiences actively choose what to watch, which means they’re more engaged with the content - and the ads. What makes it even better is the precise targeting it offers, allowing you to zero in on specific demographics, interests, or behaviors, all while delivering the visual impact of TV advertising.

Digital audio advertising is another powerful option, especially since it connects with people during their daily routines. Unlike display ads, audio ads face less competition for attention, as listeners often can’t skip or ignore them. This creates a captive audience that’s more likely to fully absorb your message.

Then there’s digital out-of-home advertising, which reaches audiences when they’re out and about, away from their screens. These ads are particularly effective for local businesses or campaigns with location-based targeting, helping you connect with potential customers when they’re in the right place - like near your store or within a relevant neighborhood. Together, these channels create a steady stream of touchpoints and provide valuable performance insights.

By diversifying your ad spend, you gain access to fresh audiences across multiple platforms, avoiding the burnout that comes with overusing a single channel. Plus, this multi-channel strategy offers critical data about what works best. For instance, some audiences might respond more to the visual storytelling of Connected TV, while others connect better with the personal feel of audio ads. Armed with this data, you can make smarter decisions about where to allocate your budget based on actual results - not just assumptions.

Another perk of diversification? It provides a safety net against platform-specific challenges, like algorithm changes, policy shifts, or seasonal audience fluctuations. If one channel underperforms temporarily, your other channels can pick up the slack, ensuring a steady flow of leads and revenue for your business.

3. Use Dynamic Creative Optimization (DCO)

Dynamic Creative Optimization (DCO) simplifies the process of creating effective ad campaigns by automatically testing and adjusting various creative elements - like headlines, images, and calls-to-action - in real time. Instead of manually producing countless ad variations, DCO leverages machine learning to determine which combinations resonate most with specific audiences and prioritizes showing those high-performing versions. This smart approach ensures better results across all segments of your campaign.

One of DCO's standout features is its ability to personalize ads on a large scale. For instance, if someone browses a travel site for flights to Hawaii, DCO might deliver an ad showcasing tropical beaches, vacation deals, and a "Book Your Getaway" button, perfectly aligned with their interest in a Hawaiian escape.

What makes DCO even more powerful is its capacity for constant optimization. Unlike traditional A/B testing, which can take weeks to yield results, DCO refines creative combinations in just hours. By analyzing every impression, click, and conversion, it quickly identifies what works best for different audience groups, improving performance with each interaction.

Another major benefit is how DCO addresses creative fatigue - a common issue where audiences lose interest after seeing the same ad repeatedly. DCO combats this by rotating through various creative combinations automatically, keeping your ads fresh and engaging. This is particularly useful for extended campaigns, where static ads often lose their effectiveness over time.

Beyond immediate campaign performance, DCO provides valuable insights for future creative strategies. You might learn that certain color palettes appeal more to younger audiences, specific headlines drive higher mobile conversions, or particular product images resonate with loyal customers. These insights can shape not only your programmatic advertising but also your broader marketing efforts across all channels.

4. Focus on First-Party Data and Privacy-Compliant Targeting

First-party data is one of your strongest tools in programmatic advertising. This is the data you gather directly from your customers - whether through website visits, purchases, or subscriptions. It gives you a clear window into how your audience behaves and what they prefer. Unlike third-party data, which comes from external sources, first-party data is yours to own and manage, offering more reliable and actionable insights.

Using first-party data not only sharpens your targeting but also helps cut costs. When you focus on people who’ve already shown interest in your brand, your campaigns become more precise and impactful. Plus, this approach aligns with privacy regulations, making it both effective and compliant.

Privacy laws like the California Consumer Privacy Act (CCPA) emphasize the importance of collecting data directly from users. These regulations encourage businesses to rely less on third-party sources and instead build their own data assets. By collecting information through customer interactions - like downloads, signups, or other opt-in actions - you can create audience segments that reflect genuine interest. These segments can then be used to retarget users, create lookalike audiences, or fine-tune acquisition strategies.

Advertisers with strong privacy practices also gain access to premium inventory. High-quality publishers prefer working with brands that use consented, first-party data, which can result in better ad placements and more competitive pricing. This approach not only strengthens your targeting but also helps reduce ad spend by ensuring your dollars are spent on well-placed, effective campaigns.

To make the most of first-party data, it’s essential to collect insights at every customer touchpoint. Whether it’s through email interactions, website activity, or app usage, integrating these data streams allows you to refine your audience segments for better performance and efficiency.

5. Optimize Supply Path and Work with Premium Publishers

Supply Path Optimization (SPO) is a smart way to lower programmatic advertising costs while improving ad quality. By working directly with premium publishers, you can cut out unnecessary intermediaries that inflate costs and reduce transparency.

The programmatic advertising ecosystem is often cluttered with multiple layers - supply-side platforms (SSPs), ad exchanges, and other vendors - all taking a share of your ad budget. Optimizing your supply path helps reduce these layers, ensuring more of your budget goes toward actual ad placements. This strategy is widely adopted, with 87% of brands, agencies, and demand-side platforms actively using SPO techniques.

Partnering directly with trusted publishers not only saves money but also guarantees better ad placements. These relationships allow you to secure premium inventory at lower CPMs, giving you greater control over where your ads are displayed.

Streamlining supply paths also helps eliminate auction duplication. Studies reveal that only 51% of ad spend reaches publishers, with 15% lost to an unexplained gap. By optimizing supply paths, you can reduce ad waste by up to 30% and avoid spending around 25% of your budget on low-quality inventory.

Working with premium publishers offers additional benefits like enhanced brand safety and fraud prevention. Direct relationships with reputable publishers reduce the risk of ad fraud and ensure your ads are shown in environments that align with your brand values. This is critical, especially as global ad fraud losses are expected to hit $172 billion by 2028.

Transparency is another major advantage. By simplifying your supply chain and working directly with publishers or through streamlined channels, you gain better insight into where your ads appear and how your budget is spent. This visibility helps you make smarter media-buying decisions and uncover new opportunities for optimization. These transparency benefits complement the cost-saving strategies already discussed.

Beyond saving money, SPO improves efficiency. Streamlined supply paths reduce latency and speed up ad delivery, which enhances user experience and campaign performance. With 31.63% of users abandoning websites that load slowly, fast ad delivery is essential.

To get started with supply path optimization, focus on identifying your strongest publisher relationships and SSPs. Evaluate your current supply chain to spot inefficiencies and redundancies, then consolidate your buying through the most effective channels. This not only trims costs but also simplifies campaign management and boosts overall results.

6. Monitor Performance and Reallocate Budget Regularly

Once you've set your campaigns in motion, keeping a close eye on performance and adjusting your budget accordingly is essential for staying efficient. Regular monitoring helps you avoid overspending and focus your resources on what delivers the best results.

Start by consistently tracking key metrics like CPA (Cost Per Acquisition), ROAS (Return on Ad Spend), and click-through rates. These insights help you spot opportunities to save money and avoid wasting your budget on underperforming channels or audiences.

Make it a habit to review performance daily and analyze insights weekly. This allows you to identify trends and make informed adjustments. Look for consistent patterns over three to five days before reallocating budgets. When you see a campaign segment performing well, increase its budget gradually. At the same time, reduce spending on areas that aren’t delivering results. This steady approach keeps your campaigns stable while optimizing for better outcomes.

For example, Connected TV might offer lower CPMs during certain times of the day, while digital out-of-home advertising could perform better for specific demographics. By comparing results across all channels, you can shift your budget to the most cost-effective options that align with your goals.

Audience analysis is another key area to watch. By reallocating funds toward high-intent audiences, you can lower conversion costs. Track which audience segments are most engaged and converting well, then increase their budget share to maximize returns.

Automated rules can simplify budget adjustments without sacrificing control. For instance, you can set thresholds to automatically increase budgets for ad groups with CPAs 20% below target or pause campaigns that consistently run over budget. These rules save time while ensuring your budget is spent wisely.

Geographic performance is another factor to consider. Certain regions or cities often deliver better results due to lower competition or higher audience engagement. Regularly review geographic data to identify these areas and reallocate your budget to get the most out of these opportunities.

Timing also plays a big role. Some audiences are more active during specific hours, leading to lower CPCs and higher conversion rates. By shifting your budget to these peak times, you can cut costs while improving results.

Finally, keep seasonal trends and market changes in mind. Consumer behavior fluctuates throughout the year, which impacts channel performance and costs. Regular monitoring ensures you can adapt your budget to these shifts and continue investing in the most effective options. These adjustments, made in real time, are crucial for staying competitive and maintaining cost efficiency.

7. Maintain Brand Safety and Avoid Low-Quality Inventory

Safeguarding your brand's reputation while ensuring your ad spend is effective requires a sharp focus on where your ads appear. Low-quality placements not only harm your brand image but also waste valuable resources. Just like budget monitoring, keeping your brand safe is essential to reducing unnecessary spending.

Brand safety today goes beyond steering clear of universally inappropriate content. It's about tailoring ad placements to reflect your brand's identity and values. For instance, a luxury brand might avoid being associated with celebrity gossip, while an entertainment brand could thrive in pop culture spaces. This kind of precision ensures your ads resonate with the right audience and uphold your brand's image.

Here’s why it matters: More than 68% of consumers say they lose trust in a brand permanently if its ad appears next to offensive content. This erosion of trust can directly impact revenue and increase customer acquisition costs. By enforcing strict brand safety standards, you not only protect your reputation but also optimize your advertising performance.

Another critical aspect is combating fraudulent and low-quality impressions. Ad fraud, such as fake traffic from spoofed sites, drains budgets and distorts performance metrics. In fact, Made-for-Advertising (MFA) sites account for as much as 15.3% of ad spend. This means money is being funneled into platforms that deliver little to no value.

To tackle these issues, use AI-powered tools that analyze content context in real time. Automated controls, like block lists for flagged domains and allow lists for trusted sites, can filter out low-quality inventory before you spend a dime. These tools help ensure your ads appear only in environments that align with your brand's standards.

Transparency is another non-negotiable. Partner with platforms that provide detailed reporting on where your ads are placed and the costs associated with each placement. This level of clarity allows you to spot problems early and shift your budget to better-performing, brand-safe options.

With over 252,000 new websites launching daily in 2024, the sheer volume of content makes traditional blocking methods less effective. Regular audits of your ad placements can help you stay ahead of new risks and remove problematic sites as they emerge.

Geographic and demographic targeting also play a key role in maintaining brand safety. Different regions and audience groups consume content differently, so monitoring these trends ensures your safety measures remain effective across all markets.

Cost-Saving Strategy Comparison

After diving into individual cost-saving methods, let’s compare their strengths and challenges. Choosing the right approach depends on your budget, expertise, and campaign objectives. Each method varies in terms of savings potential, complexity, and associated risks.

AI-powered bidding stands out for its savings potential, with Google reporting up to 30% cost-per-acquisition (CPA) reduction. While it’s highly effective, it requires moderate technical setup and ongoing oversight to avoid over-reliance on automation and ensure data quality.

Dynamic Creative Optimization (DCO) is another strong contender, improving engagement and conversion rates with real-time personalization. Although implementation requires creative automation tools and collaboration between creative and technical teams, the payoff can be substantial. However, risks like creative fatigue and data privacy concerns should be managed carefully.

Channel diversification - spreading investments across Connected TV, audio, and digital out-of-home - offers moderate to high savings by reducing over-reliance on a single platform. It’s relatively simple to implement but comes with challenges like fragmented reporting and inconsistent metrics.

First-party data targeting is a forward-looking strategy, especially as third-party cookies phase out. It offers moderate savings while maintaining reach. However, it’s the most complex to execute, requiring significant investment in data infrastructure and compliance. Limited data collection can also restrict scalability.

Supply path optimization focuses on reducing fraud and improving CPM rates, delivering moderate savings. This approach demands a solid understanding of the market and strong publisher relationships. The main risk lies in being overly restrictive, which could limit access to valuable inventory.

Here’s a quick comparison of these strategies across key factors:

These insights can help you align cost-cutting strategies with your advertising goals and available resources.

For small advertisers, starting with AI-powered bidding and Dynamic Creative Optimization can deliver quick wins. These methods are impactful without requiring heavy upfront investment.

For larger advertisers, supply path optimization and building premium publisher relationships are key to scaling effectively. Bigger budgets provide leverage for negotiating direct deals and securing competitive bulk rates.

Budget reallocation, while moderately complex, requires careful analytics integration to avoid over-optimization driven by short-term fluctuations. On the other hand, brand safety measures - like vetting partners - are easy to implement but may lead to higher CPMs for premium inventory.

Regardless of your size or strategy, real-time monitoring and brand safety practices are essential to protecting your investment and ensuring consistent performance.

Conclusion

Lowering programmatic ad costs in 2025 requires a thoughtful and multi-layered strategy. The seven approaches we've discussed - ranging from AI-driven bidding to prioritizing brand safety - are most effective when combined into a well-rounded cost management plan.

Staying proactive is crucial. With low-quality content increasing by 19% each year, advertisers who take a hands-off approach risk wasting large portions of their budgets on poorly performing placements. Consistent monitoring allows you to identify and resolve performance issues quickly.

Diversifying your ad channels is another key element. It prevents over-reliance on a single platform, which can lead to diminishing returns. Building direct relationships with publishers can also help secure lower CPMs and bulk discounts. These partnerships not only improve cost efficiency but also strengthen brand safety.
