What is CPA and How to Reduce It?

Maximizing the CPA of Advertising Campaigns

When creating online advertising campaigns, there are many payment models available, and the advertiser must choose the most suitable one according to the campaign’s objectives.

Today, from our digital marketing agency in Gijón, we will talk about CPA and how it might be specifically beneficial for certain types of businesses.

Let’s get started!

What is CPA?

CPA, also known as Cost Per Acquisition, is a payment model found in digital advertising. In this case, the value indicates how much it costs the advertiser to achieve a sale.

It’s crucial to clearly differentiate between Cost Per Acquisition and Cost Per Action, where the latter is based on the results obtained from the campaign, specifically when the user performs an action like downloading or filling out a form.

Understanding and monitoring CPA allows us to deeply assess whether the campaigns are profitable.

Why is Knowing CPA Important?

Knowing your CPA is a highly valuable and important aspect for a business, and here are the reasons why:

You can determine whether your actions are effective: When developing a strategy, it’s essential to have real data for evaluation. This metric will let you know if your earnings exceed your investment and if the campaign is being executed effectively.

Identify strengths and weaknesses: As strategies develop, adjustments or improvements are often necessary. CPA provides real-time insights into what is working and what is not.

Evaluate ROI: Return on Investment is critical for a business to function well. Calculating this metric provides specific data on the capital gained and whether continuing with the current plan is viable.

Make optimization adjustments: If earnings are equal to or greater than the investment, no major changes are needed—just small tweaks or adjustments to the campaigns.

How is CPA Calculated?

To determine your CPA, divide the total advertising spend by the number of acquisitions made.

Examples of CPA Calculation

The first example to understand how CPA is calculated will involve a business selling water bottles. Over 8 months, the expenses were:

• €2,000 in physical store advertising.
• €2,500 in digital advertising.
• €4,000 in logistics.
• €12,000 in salaries.

The total expenses amount to €20,500.

Suppose that during these 8 months, we acquired 3,000 customers.

CPA = €20,500 / 3,000 = €6.83

In the second example, let’s assume we’re selling tablets, and over two years, the following expenses were incurred:

• €800,000 in physical store advertising.
• €500,000 in digital advertising.
• €500,000 in software.
• €1,500,000 in salaries.

The total expenses amount to €3,300,000, and the customers acquired were 20,000.

CPA = €3,300,000 / 20,000 = €165

With these CPA figures and considering the profit per customer, you need to assess whether the business is profitable.

How Does CPA Bidding Work in Ads?

CPA bidding doesn’t work like other bidding models; here, the ad with the best ranking wins. Several elements are considered to determine the ad’s ranking:

• Bid amount.
• The quality of the ad at the time of the auction.
• Ad relevance.
• The functionality of the landing page.
• The user’s search context.

For Cost Per Acquisition to be effective for your business, the content must be relevant and attractive. Ads with higher quality levels achieve a lower Cost Per Acquisition.

On the other hand, Google penalizes ads with poor content, giving them a lower score and thus a higher Cost Per Acquisition.

We’ve discussed the importance Google places on content quality on numerous occasions, both for SEM and organic ranking. We explain this well in our SEO GUIDE.

Advantages and Disadvantages of CPA Bidding

Every payment model within Google Ads presents different objectives, so it’s essential to weigh the advantages and disadvantages CPA can bring to your business.

Advantages of Using CPA Bidding

• It relates to Return on Investment, as there is a direct connection between the ad and the sale.
• This payment model seeks to persuade the user to take action in a less intrusive way.

Disadvantages of Using CPA Bidding

• It’s suitable for certain types of campaigns when we have a direct attribution model and short-term results.
• If the strategy is not fully planned, the CPA could end up being too high.

What Types of Ads Use CPA the Most?

It’s essential to know which types of ads are most suitable for applying CPA, as not all are appropriate. The idea is to use it in ads where results can be analyzed immediately and directed towards the sales process.

For small businesses, this can be a great help, as well as for entrepreneurs working to increase sales and leads over a short period.

For example, startups can use this payment model because they focus on marketing and selling products and services using intensified ICT.

Some examples of conversions include:

• Making a purchase, subscription, or buying a product.
• Receiving email addresses or other relevant data to complete a database.
• Completing a survey.
• Signing up for software for a specified period.

How Can We Reduce CPA?

As explained earlier, the higher the quality of the ad, the lower the CPA. Therefore, it’s crucial to craft the ad, keywords, and design carefully for better performance.

The landing page should be simple yet compelling, providing value and conveying messages clearly and directly. Including videos or animations can help retain user attention, as well as removing outbound links to avoid distractions.

Consider the following aspects:

• Create good content within the ad: The more effective the ad, the lower the CPA. Thus, find ways to capture the audience’s attention with interesting content that generates curiosity, appeals to emotions, creates a connection, and uses visual resources.
• Optimize investment: Analyze when conversion rates increase or decrease, such as specific hours or days of the week, and adapt the ad’s visibility accordingly. The goal is to identify a common behavior pattern.
• Review account structure: The structure of the account influences the CPA, so carefully consider audience targeting, keywords, and more.
• Campaign budget: Consider and analyze metrics, impression percentages, and other factors to determine what remains to be spent in the campaign.
• Align bids with the campaign budget: Aligning bids with the budget is ideal for improving efficiency.
• Keywords and targeting: Keywords are a fundamental part of campaigns, so optimizing them to improve CPA is essential.
• Bid adjustments without keywords: With Google Ads, you can increase or decrease bids for various dimensions, including devices, audience, demographics, time of day, or week.
• Keyword expansion: Discover a broad range of relevant terms and find new opportunities.
• Ad personalization: The most important thing to reduce CPA is creating quality ads. Ad relevance is a fundamental pillar within quality scores.
• User journey personalization: For any conversion, include personalized guidance based on how the user interacts on the website. Additionally, consider that the user needs to go through several touchpoints to move from knowing nothing about the brand to feeling comfortable making a purchase.
• Post-click optimization: Improving engagement and conversion rates on landing pages after the click helps increase efficiency**.** The entire website should be considered to reach the potential audience.
• Data integration: Google considers data integration crucial for advertisers to achieve strong campaign growth and better bids.
• Automated bidding strategies: These include maximum conversions and maximum conversion value bids. This approach can align with an efficiency goal using target Cost Per Acquisition or target Return on Ad Spend.
• Recommendations section: These recommendations help improve campaigns. They include keywords, bids, audiences, ads, etc., providing an ideal opportunity to identify improvement areas.
• Adjust conversion settings: There are many options that can influence CPA and can be configured through this panel.

Knowing how to reduce CPA will be valuable for achieving a good ad quality score and making your strategy more effective. Advertisers and businesses must carefully plan their strategy to maximize campaign performance and reach objectives in the most cost-effective way possible.
