Cost Per Order (CPO) is a critical Key Performance Indicator (KPI) for e-commerce companies to measure the efficiency of their advertising campaigns. By analyzing the CPO, companies can determine the direct impact of their advertising spend on sales.
Keeping the CPO in check ensures that advertising efforts are financially viable and sustainable, and that marketing dollars are being spent wisely.
Key Takeaways
- Definition: Cost Per Order (CPO) is the average cost an e-commerce business incurs through advertising to generate a sale.
- Calculation: CPO is derived by dividing total advertising spend by the number of orders generated by paid campaigns in a given period.
- Strategic Importance: Monitoring CPO ensures advertising is financially viable, aligns with profitability goals, and refines marketing strategies.
- Optimization Strategies: Reducing CPO includes optimizing ad targeting, diversifying ad platforms, increasing organic traffic, and testing ad creative.
- Limitations: While valuable, CPO doesn’t reflect lifetime customer value, can vary by marketing channels, doesn’t account for customer loyalty, offers no insight into profit margins, is influenced by marketing campaign variations, isn’t a sole indicator of business health, may promote short-term thinking, and needs additional metrics for comprehensive analysis.
- Complementary Metrics: In addition to CPO, metrics such as return on ad spend (ROAS), click-through rate (CTR), and conversion rate provide a comprehensive view of advertising effectiveness.
Why does Cost Per Order matter for your business?
Understanding and optimizing CPO is paramount for ecommerce businesses for several reasons:
- Profitability Assurance: Monitoring CPO helps in ensuring that the cost of acquiring a sale through advertising doesn’t overshadow the profit derived from that sale.
- Budget Effectiveness: By tracking CPO, businesses can evaluate the efficiency of their advertising budget and ascertain if the funds are producing the desired return on investment.
- Marketing Strategy Refinement: Analyzing CPO allows businesses to fine-tune their marketing strategies, reallocating budget to campaigns that yield lower CPOs.
- Customer Acquisition Insights: A fluctuating CPO can provide insights into the effectiveness of various advertising channels, enabling businesses to focus on channels that yield the best results at the lowest cost.
- Financial Forecasting: CPO metrics aid in budget planning, helping businesses predict future advertising expenditure based on sales targets.
How to calculate Cost Per Order (CPO)?
Explanation of the parts of the formula:
- Total Paid Orders refers to the number of transactions on the website where customers have successfully made a payment. This is the total number of completed sales generated through the advertising campaign.
- Ad Marketing Costs is the total expenditure a business has put into its advertising campaigns within a specific period. This includes money spent on platforms like Google Ads, Facebook Ads, and other marketing channels, as well as associated fees and costs.
- When you divide the Total Paid Orders by the Ad Marketing Costs, the resulting value gives an average cost incurred to obtain a single order through the advertising campaigns. This essentially quantifies how much money is spent to achieve one sale from the ad campaign.
In essence, the Cost Per Order (CPO) is a metric that provides an average amount a business spends on advertising to acquire a single sale. A lower CPO is generally desirable as it indicates that the advertising efforts are more cost-effective.
Example Scenario
Imagine the following situation over a specific period:
- Your business spent $5,000 on various advertising campaigns.
- From these campaigns, you received 250 orders on your website which were successfully paid.
Insert the numbers from the example scenario into the formula:
- Cost Per Order (CPO) = 250 orders / $5,000
- Cost Per Order (CPO) = $20 per order
This means that for every order placed on the website as a result of the advertising campaigns during this period, the business spent an average of $20.
Tips and recommendations for improving Cost Per Order
To decrease Cost Per Order (CPO), it’s essential to hone advertising strategies, optimize targeting, consider alternative advertising platforms, and analyze customer feedback:
Optimize Ad Targeting
Ad targeting is a critical component of managing your cost per order (CPO). Rather than taking a blanket approach, consider focusing your advertising efforts on a more specific group of potential customers. This can be achieved by studying your customer demographics, understanding their preferences, and tailoring your ads to appeal to this group. Additionally, consider using retargeting strategies for individuals who have previously interacted with your brand, as they are more likely to convert to sales.
Test different ad creative and copy
To ensure the success of your advertising campaign, it’s important to experiment with different ad creative and copy. This process, often referred to as A/B testing, allows you to understand which ad elements are most effective at driving conversions. You may find that a particular color scheme, image choice, or copy style resonates better with your audience. By identifying what works best, you can optimize your ads for maximum impact and lower your CPO.
Explore alternative ad platforms
While popular advertising platforms can offer broad reach, they often come at a high cost. To manage your CPO, consider exploring alternative platforms that may offer a more cost-effective solution. For example, if your target audience is younger, platforms like TikTok or Snapchat may provide better results at a lower cost. It’s all about knowing where your audience spends their time and reaching them there.
Analyze and adapt
Advertising strategies should never be set in stone. To successfully reduce your CPO, it’s important to continually review your campaign metrics and adjust your strategies accordingly. This means looking at what’s working, what’s not, and making the necessary adjustments to improve performance. This could mean adjusting your bidding strategy, changing your targeting parameters, or even redesigning your ad creative.
Drive organic traffic
While paid advertising plays a key role in driving sales, it’s also important to invest in strategies that drive organic traffic. This could include search engine optimization (SEO), content marketing, or social media engagement. These strategies often require an upfront investment of time and resources, but can lead to sustained traffic growth over time. By increasing organic sales, you can offset the cost of your paid campaigns and effectively reduce your overall CPO.
Examples of use
Refined Audience Targeting
- Scenario: An ecommerce platform selling handmade jewelry notices a high CPO for its broad-targeted Facebook ads.
- Use Case Application: The platform could segment its audience based on past purchasing behavior, interests, or demographics. By crafting ads specifically for these segments and targeting them, the brand may notice a significant reduction in CPO as the relevance of ads to the audience increases.
Ad Platform Diversification
- Scenario: A DTC tech gadget store finds its Google AdWords campaigns are yielding a high CPO.
- Use Case Application: The store could explore alternative platforms like Bing Ads or niche tech forums for advertising. By diversifying the advertising platforms and targeting audiences in different spaces, the overall CPO might decrease.
Optimized Ad Creative
- Scenario: An online bookstore is not seeing the expected returns from its Instagram ad campaigns.
- Use Case Application: Through A/B testing, the bookstore could experiment with different visuals, copy, and calls to action. By analyzing which ad version yields the lowest CPO, they can optimize future campaigns accordingly.
User Experience (UX) Enhancement
- Scenario: An online shoe store finds that while its pay-per-click ads drive a lot of traffic to its site, the conversion rate is low, raising the CPO.
- Use Case Application: By analyzing the user journey, the store might realize that a complicated checkout process or non-responsive design is the barrier. Enhancing the UX and simplifying the purchase journey could result in a higher conversion rate and a reduced CPO.
Retargeting and Remarketing
- Scenario: A luxury watch retailer identifies that a lot of its website visitors are dropping off without making a purchase.
- Use Case Application: Using the CPO metric, the retailer could launch retargeting ads specifically to these visitors, reminding them of the products they viewed or left in their cart. Since these consumers have already shown interest, they might convert at a lower CPO compared to cold prospects.
Cost Per Order SMART goal example
Specific – Reduce the Cost Per Order (CPO) by 20% (from the current cost of 10 EUR to 8 EUR per order).
Measurable – CPO will be tracked and compared bi-weekly using the eCommerce analytics and ad platforms before and after implementing cost-saving and marketing efficiency strategies.
Achievable – Yes, by refining the advertising target audience, optimizing ad placements, improving the conversion rate on the website, and renegotiating vendor contracts or seeking cost-effective alternatives.
Relevant – Yes. Reducing the CPO directly influences profitability. Lowering this cost aligns with the quarterly goal of increasing profit margins while maintaining or even increasing the order volume.
Timed – Within a period of four months from the start of strategy implementation.
Limitations of using Cost Per Order
While Cost per order (CPO) is an essential metric for understanding the cost of acquiring a sale in e-commerce, it has several limitations when used for in-depth business analysis:
- Doesn’t Reflect Lifetime Customer Value: CPO focuses on the immediate cost to acquire a single sale. However, it doesn’t account for the potential future revenue a customer might bring, which can provide a deeper insight into the true cost and value of customer acquisition.
- Can Vary Based on Marketing Channels: Different marketing channels may have different CPOs. For instance, search engine marketing might have a higher CPO than email marketing. Thus, focusing solely on the aggregate CPO can misrepresent the efficiency of different channels.
- Doesn’t Account for Customer Loyalty: A low CPO is ideal, but if these customers are not returning for subsequent purchases, the long-term value and ROI could be poor.
- No Insight into Profit Margins: A low CPO is not always synonymous with high profitability. If the order values are low or if the products sold have thin margins, then a low CPO might not guarantee good profit.
- Subject to Marketing Campaign Variations: Promotional campaigns, discounts, and other marketing strategies can influence CPO. It’s crucial to contextualize CPO within specific campaigns or time frames.
- Not Indicative of Overall Business Health: A low CPO might seem promising, but if other metrics like Average Order Value (AOV) or retention rate are suffering, the business might still be in trouble.
- May Encourage Short-Term Thinking: By overly focusing on reducing CPO, businesses might neglect long-term strategies or investments that could lead to sustained growth and higher lifetime customer value.
- Lacks Depth Without Additional Metrics: CPO, when viewed in isolation, doesn’t capture the entirety of business performance. For example, a high CPO might be acceptable if the lifetime value of customers is significantly high, leading to substantial long-term profits.
In summary, while CPO is a useful measure of the cost-effectiveness of sales acquisition, it must be evaluated alongside other metrics to provide a holistic understanding of e-commerce performance. Relying solely on CPO can potentially mislead strategic decisions.
KPIs and metrics relevant to Cost Per Order
Several other metrics are relevant to Cost Per Order to offer a comprehensive perspective on advertising efficacy:
- Return on Ad Spend (ROAS): This measures the revenue generated for every dollar spent on advertising. A high ROAS and a low CPO can indicate a highly effective ad campaign.
- Click Through Rate (CTR): Represents the ratio of users who click on an ad to the number of total users who view the ad. A high CTR but high CPO could mean the ad is appealing but isn’t converting effectively.
- Conversion Rate: This is the percentage of ad clicks that result in a purchase. If CPO is high but the conversion rate is low, the advertising might be reaching the wrong audience.
By monitoring CPO alongside these metrics, businesses can adopt a holistic approach to their advertising strategies and achieve better financial outcomes.
Final thoughts
Cost Per Order (CPO) is an essential metric for e-commerce businesses to ensure that their advertising efforts are both effective and economically sound. By regularly monitoring and optimizing CPO, businesses can refine their advertising strategies to ensure maximum sales at minimum cost.
