With a focus on maximising ROI for brands, Andrea brings a wealth of experience in influencer partnerships and social media analytics. In this article, she dives into the essentials of CPA, offering a comprehensive look at why this metric matters in today’s landscape and how brands can leverage it for sustainable growth.

As digital marketing grows ever more far-ranging and complex in its scope, it also continues to become more measurable and standardised. This has placed a sharp focus on maximising ROI and led to performance metrics becoming indispensable indicators of success for an individual strategy or overall campaign. 

Brands are increasingly turning to Cost Per Acquisition (CPA) as a key indicator of campaign success. For marketing and communication professionals, brand leaders, and content creators, understanding the value of CPA has become essential in gauging the return on investment from influencer partnerships and social media campaigns.

In this article, I’ll explore why CPA matters, how it aligns with performance goals, and what your brand can do to optimise it. 

Why CPA is Crucial for Brands in a Performance-Driven World

Measuring performance through CPA has become essential for brands looking to maximise their investment. While influencers, for example, were initially seen as valuable partners for generating awareness, the demand and need from brands have evolved: investments must have a clear impact on the bottom line of a brand’s funnel, shifting from vanity metrics to performance-driven results. CPA provides a direct and tangible business metric on what the outcome of partnerships can achieve.

For instance, in our collaboration with Airalo, CPA allowed us to highlight the precise impact of influencer partnerships on customer acquisition, underscoring the tangible value that influencer marketing can bring when aligned with clear objectives.

Beyond Vanity Metrics: How CPA Measures Real Impact in Influencer Marketing

The bottom line for brands can vary beyond direct sales. Metrics such as customer acquisitions, app downloads, form submissions, product reviews, and subscriptions are just as important. For influencer campaigns to drive sustainable value, brands must evaluate talents not only on their ability to generate views but also on their capability to inspire consumer action. Performance-driven campaigns now require a balance between reach and impact, making it necessary to assess conversion rates as part of the overall content quality and the effectiveness of a partnership.

Despite this shift in focus, many talent agents and independent creators have yet to fully adapt. Historically, influencer fees were tied to follower count and engagement, but that model is becoming outdated. Today, brands are demanding more concrete proof of influence. The value proposition of an influencer is no longer just about reach but how deeply they resonate with their audience and can drive consumer behaviour. This has led to a need for creators to evolve their pitch to include performance metrics, making their conversion power a key selling point.

Negotiating Partnerships with CPA Benchmarks

Performance metrics should be central to partnership negotiations, and brands need to prioritise CPA benchmarks and work towards defining industry-wide standards for performance evaluation. For example, the CPA for a macro influencer in the F&B sector will differ from the CPA of a mid-tier influencer promoting a lifestyle app.

This distinction is crucial as it enables brands to set realistic expectations and target metrics based on influencer tier and industry. The product or service price point also has a direct impact on CPA, with higher-priced items typically requiring a more personalised, trust-driven approach to reduce acquisition costs.

Mastering CPA: Transforming Influencer Marketing into Tangible Business Growth

Achieving a balanced CPA requires a nuanced approach that considers product price, target audience, and desired consumer action. For instance, products with a long-term commitment might benefit from an introductory offer, while impulse buys might perform best with limited-time promotions. Understanding consumer behaviour and creating content that resonates with these insights enables brands to optimise their CPA effectively.

Product seasonality is another important factor in CPA management. The cost to acquire a customer may shift throughout the year, depending on product relevance and market demand. For example, an influencer campaign for winter apparel will have a different CPA in summer versus the peak holiday season. A flexible approach allows brands to adapt CPA targets based on market conditions, ensuring they are competitive and realistic.

Creating a Feedback Loop for Continuous Improvement

One of the most effective strategies for brands is to build a feedback loop between the campaign execution and product development teams. By closely analysing the sentiment generated by the content, brands can gather critical consumer insights that inform future product launches and an immediate shift in the strategies, such as promo adaptation or pricing communication strategy.

For some product categories, a percentage discount can work wonderfully versus a fixed price discount. However, it is only through a test-and-learn approach and campaign adaptability that these insights can be tested. This loop ensures that campaigns are not just evaluated on their immediate CPA but also on their long-term contribution to brand growth, product iteration, and consumer trust. This ongoing adjustment cycle helps brands fine-tune their offerings to meet market demand and maintain a competitive CPA.

Conclusion: CPA as a Benchmark for Sustainable Growth

CPA is a vital metric that helps brands quantify the true impact of campaigns on their bottom line. By focusing on performance metrics and adapting to factors like product seasonality and consumer trust, brands can build successful campaigns that drive measurable outcomes. As the industry continues to mature, CPA benchmarks will become increasingly standardised, allowing for more strategic partnerships and clearer expectations across the board.
