KPIs for Marketing: cost per impression

Learn how to measure the effectiveness of your marketing campaigns with cost per impression (CPI) as a key performance indicator (KPI).

Are you looking for a way to measure the success of your marketing campaigns? Look no further than Key Performance Indicators (KPIs). KPIs are measurable goals that help you track your progress and make data-driven decisions for your marketing strategy. In this article, we will be focusing on one key KPI: cost per impression (CPI).

Understanding Key Performance Indicators (KPIs) in Marketing

Before diving into CPI, it's essential to understand the role of KPIs in marketing. KPIs are essential metrics that help you evaluate the effectiveness of your marketing campaigns and strategies. They allow you to set goals, measure progress, and optimize your marketing efforts for success.

The role of KPIs in marketing strategy

By tracking KPIs, you can measure the ROI of your marketing investments and understand how various campaigns and channels contribute to your overall marketing strategy. This data-driven approach enables you to adjust your marketing strategy to maximize budgets and optimize campaigns with high ROI.

For instance, let's say you're running a social media campaign to promote a new product. By tracking KPIs such as CTR and conversion rates, you can determine which social media platforms are driving the most traffic and conversions. You can then adjust your marketing strategy to focus more on those platforms and allocate your budget accordingly.

Common marketing KPIs

Some common KPIs include:

  • Click-through rates (CTR): The percentage of people who click on a link in your ad or email.
  • Conversion rates: The percentage of people who take a desired action, such as making a purchase or filling out a form.
  • Customer acquisition costs (CAC): The cost of acquiring a new customer, including advertising, marketing, and sales expenses.
  • Customer lifetime value (CLV): The total revenue a customer generates for your business over their lifetime.

Each KPI tracks a different element of your marketing campaign, but they work together to achieve the ultimate goal: achieving a healthy ROI. By regularly monitoring and analyzing your KPIs, you can make data-driven decisions to optimize your marketing strategy and drive business growth.

In addition to the above-mentioned KPIs, other important metrics to consider include bounce rate, engagement rate, and lead-to-close ratio. By analyzing these metrics, you can gain deeper insights into your audience and adjust your marketing strategy accordingly.

Overall, KPIs are critical to the success of any marketing campaign. By tracking and analyzing these metrics, you can measure the effectiveness of your marketing efforts, identify areas for improvement, and optimize your strategy for long-term success.

Introduction to Cost Per Impression (CPI)

CPI is a KPI that measures the average cost of each time your ad appears to a viewer. It is commonly used as a metric for online advertising and is a key factor in evaluating the effectiveness of marketing campaigns.

Definition of Cost Per Impression

In simple terms, CPI is calculated by dividing the total cost of your ad impressions by the number of impressions received. It is expressed as a cost per thousand impressions (CPM) metric, which represents the cost of getting your ad seen by 1,000 viewers.

However, it is important to note that not all impressions are created equal. Some impressions may be more valuable than others, depending on the context in which they are displayed. For example, an impression on a highly targeted website with a relevant audience may be more valuable than an impression on a general website with a broad audience.

How CPI is calculated

Let's say your campaign cost $10,000, and it received 100,000 impressions. Your CPI would be $100 (10,000/100,000*1000). While this metric varies across industries and channels, the lower your CPI, the better. It means you're reaching more people at a lower cost, increasing the chances of conversion.

It's important to keep in mind that CPI is just one metric in a larger advertising strategy. While a low CPI is desirable, it's not the only factor that determines the success of a campaign. Other metrics, such as click-through rate (CTR) and conversion rate, should also be considered when evaluating the overall effectiveness of an advertising campaign.

Furthermore, CPI can be influenced by a variety of factors, including the ad format, targeting options, and bidding strategy. Testing different variables and analyzing their impact on CPI can help optimize your advertising campaigns for better results.

The Future of CPI

As the advertising landscape continues to evolve, so does the importance of CPI as a metric. With the rise of programmatic advertising and real-time bidding, advertisers are able to target their audiences more precisely and efficiently than ever before. This has led to increased competition and a focus on optimizing CPI to get the most out of advertising budgets.

Additionally, the growth of mobile advertising has also impacted CPI. With more people accessing the internet and consuming content on mobile devices, advertisers must consider the unique challenges and opportunities of mobile advertising. Factors such as screen size, user behavior, and ad placement can all impact CPI on mobile devices.

In conclusion, CPI is a valuable metric for measuring the effectiveness of advertising campaigns. While it's important to strive for a low CPI, it's just one piece of the puzzle. By analyzing multiple metrics and testing different variables, advertisers can optimize their campaigns for better results and stay ahead in a rapidly evolving advertising landscape.

Importance of Cost Per Impression in Marketing

CPI, or Cost Per Impression, is an essential metric for any business that wants to evaluate the effectiveness of their marketing campaigns and optimize their ad spend. It measures the cost of displaying an ad to a potential customer and is calculated by dividing the total cost of the ad campaign by the number of impressions it generates.

Tracking CPI is crucial for several reasons:

Evaluating advertising effectiveness

High CPI means that your ads are expensive and not getting enough impressions to justify the cost. A low CPI shows that your ads are being displayed to your target audience, and you're getting value for your investment. By tracking CPI, you can identify which ads are performing well and which ones need improvement.

Furthermore, you can use this information to adjust your ad targeting, messaging, and placement to increase impressions and reduce costs.

Budget allocation and optimization

Tracking CPI allows you to allocate your budget to channels that provide the best value for your investment. You can identify which channels are generating the most impressions at the lowest cost and allocate more resources to those channels.

Additionally, you can optimize and adjust campaigns to achieve the desired CPI, reduce costs, and maximize ROI. By monitoring CPI, you can make data-driven decisions to improve the performance of your ad campaigns.

Comparing different marketing channels

CPI allows you to compare the performance of different marketing channels, such as social media, search engine advertising, display advertising, and more. By comparing CPI across these channels, you can identify the best performing channels and allocate resources accordingly.

For example, you may find that social media advertising has a lower CPI than display advertising, indicating that social media is a more cost-effective channel for your business. By reallocating resources from display advertising to social media advertising, you can increase impressions and reduce costs.

In conclusion, tracking CPI is essential for evaluating the effectiveness of your marketing campaigns, optimizing your ad spend, and maximizing ROI. By monitoring CPI and making data-driven decisions, you can improve the performance of your ad campaigns and achieve your business goals.

How to Lower Your Cost Per Impression

Now that you understand CPI's importance let's examine how to lower your CPI. Here are some effective ways that can help you reduce your CPI and optimize your campaigns.

Targeting the right audience

The more targeted your audience, the lower your CPI. By analyzing your audience's data and behavior, you can create campaigns that cater to their interests and preferences, and avoid spending ad money on showing them irrelevant ads.

For example, if you are selling high-end luxury watches, you would want to target people who have shown an interest in luxury goods or watches in the past. By targeting this specific audience, you will increase the chances of your ad being relevant to them, and therefore, increase the likelihood of them clicking on your ad.

Additionally, you can also target specific demographics, such as age, gender, and location. By doing so, you can ensure that your ads are being shown to the people who are most likely to be interested in your product or service, and therefore, lower your CPI.

Improving ad quality and relevance

CPI is impacted by the quality and relevance of your ads. By investing in high-quality visuals and compelling copy that aligns with your audience's interests, you will increase engagement with your ads, and reduce your CPI.

One way to improve the quality of your ads is by using eye-catching visuals that are relevant to your product or service. For example, if you are selling a new line of sneakers, you could use high-quality images of people wearing the sneakers in different settings, such as running or playing basketball.

Additionally, you can also improve the relevance of your ads by using copy that speaks directly to your audience's pain points or desires. For example, if you are selling a weight loss supplement, you could use copy that highlights the benefits of the supplement, such as increased energy and improved overall health.

A/B testing and optimization

To optimize your campaigns, you can conduct A/B testing on various aspects of your ads, such as headlines, visuals, and calls-to-action. By comparing the performance of different versions of your ad campaign, you can improve your ad relevance and optimize your CPI.

For example, you could create two different versions of your ad campaign, each with a different headline. By testing the performance of each headline, you can determine which one resonates better with your audience and use that headline in your final ad campaign.

Similarly, you could test different visuals or calls-to-action to determine which ones are most effective in driving engagement and conversions. By continually optimizing your ad campaign, you can improve your CPI and get the most out of your advertising budget.

Cost Per Impression vs. Other Marketing Metrics

While CPI measures the cost of an ad impression, other marketing metrics are equally important in assessing a campaign's success. Here are some metrics that may be used in conjunction with CPI to evaluate your marketing efforts.

Cost Per Click (CPC)

CPC measures how much you pay each time someone clicks on your ad. It is used to evaluate the effectiveness of PPC campaigns.

Cost Per Acquisition (CPA)

CPA measures the cost of acquiring new customers. It is a crucial metric in understanding your customer acquisition costs and the value of each customer.

Return on Ad Spend (ROAS)

ROAS measures the total revenue generated from your marketing campaign for every dollar spent. It is an essential metric in assessing the profitability of your campaign and optimizing your marketing strategy.


CPI is a crucial KPI in evaluating the effectiveness of your marketing campaigns. It enables you to optimize your ad spend and adjust your campaigns to achieve a healthy ROI. By both tracking CPI and actively working to lower it, you can create successful marketing efforts that provide value to your business and the customer.
