Importance of Tracking CPM

Tracking CPM offers a wealth of benefits for businesses running advertising campaigns, including:

  • Optimize your budget: CPM helps you allocate your advertising budget more strategically. Knowing the cost to reach 1,000 impressions allows you to adjust spending to maximize audience reach while staying within budget. This ensures that every dollar spent is directed towards the most impactful areas which in turn reduces wasteful expenditure and enhances the ROI.
  • Measure campaign performance: Monitoring CPM allows you to gauge the effectiveness of your messaging and creative elements. It reveals whether your ads resonate with your target audience and generate engagement.
  • Act as industry benchmarks:  CPM metrics serve as benchmarks for industry standards and competitor analysis. This data helps you set realistic goals and understand your performance relative to others in your field.
  • Strategic Decision-Making: With CPM data, you can make informed decisions on where and how to invest your advertising budget. This includes choosing the right platforms, ad formats, and targeting strategies to achieve your campaign objectives.

The CPM Formula

The formula for calculating CPM is as follows:

CPM = (Number of Impressions / Cost of Advertising)​ × 1000

In this formula:

  • Number of impressions refers to the total instances in which an advertisement is viewed or displayed.
  • Cost of advertising denotes the total expenses spent for placing and running the advertisement.

How to Calculate CPM? 3 Simple Steps

Now, let’s explore how you can calculate CPM of your advertising campaign:

1. Determine Total Cost

Firstly, you must figure out the total cost you’ve spent on advertising your business. Consider the following points to accurately estimate this value:

  • Advertising purchases: Include costs associated with digital ads, print media, and outdoor advertising like billboards and bus wraps.
  • Marketing tools: Factor in the expenses for marketing software, CRM tools, and other platforms that assist in ad management and tracking.
  • Production costs: Account for the creation of advertising materials, such as graphic design, video production, and content writing.
  • Agency fees: If you've engaged with a marketing agency, include their fees as part of the total cost.

Pro Tip: We highly recommend using a finance management tool like Expensify or PlanGuru to keep track of your ad spending. This ensures you have a clear and organized record for calculating the precise CPM.

2. Identify Total Impressions

The next step is to find out the total number of impressions your ad receives. You can do so by following these tips:

  • Aggregate digital touchpoints: Compile data from all digital platforms where your ad is displayed. This includes social media, websites, email campaigns, and digital billboards.
  • Use analytics tools: Employ tools like Google Analytics or social media insights to track the number of times your ad has been displayed to users. Ensure that you filter out duplicate views by the same user if possible.
  • Consider offline Impressions: If your campaign extends to offline media like newspapers or TV, estimate those impressions based on circulation and viewership data provided by the media outlets.
  • Record & summarize: Keep a detailed record of impressions from each source and add them up to get the total impressions. Use spreadsheets for better accuracy and ease of updating.

Pro Tip: For digital campaigns, set up tracking pixels on your ads to automatically calculate impressions and gather detailed user engagement metrics. This feature is available in Google Analytics.

3. Apply the CPM Formula

Lastly, you can plug the gathered data into the CPM formula mentioned earlier. For accuracy, you may follow these tips:

  • Use reliable data sources: Always rely on credible and consistent data sources for your calculations. This minimizes the risk of inaccuracies caused by unreliable or fluctuating data.
  • Leverage online calculators: For precise estimates, it’s wise to try out an online CPM calculator. You can use our CPM calculator to figure out an accurate value. It’s free and reliable!
  • Cross-verify with multiple tools: Utilize multiple tools to cross-verify your CPM results. If different tools provide similar results, you can be more confident in the accuracy of your calculations.
  • Track throughout the campaign: Continuously monitor your campaign's performance to maintain accurate CPM calculations.

Pro Tip: Align your CPM calculations with your campaign goals. If brand awareness is the primary goal, a slightly higher CPM might be acceptable. For direct sales, a lower CPM is crucial.

5 Proven Tips to Optimize the CPM of Your Ad Campaign

Want to optimize the CPM of your ad campaign? Below, we’ve mentioned some proven tips that the experts at our sister agency, inBeat Agency, use.

1. Target the Right Audience

To begin, understand who your ideal customers are and segment them based on factors like behavior, location, interests, etc. You can do so by gathering data on demographics, interests, and online behavior through Google Analytics and Social Media insights.

2. Optimize Ad Placements

Ad placement can impact your ad performance. So understanding which platform works best for your campaign is a key for optimizing your CPM.

Experiment with different combinations of placements to see what works best for your target audience. For instance, you might find that ads placed in Instagram Stories perform better with a younger demographic, while LinkedIn Sponsored Content might be more effective for reaching professionals.

In addition, try automatic placement options offered by platforms like Facebook, which use algorithms to optimize ad delivery across various placements.

3. Enhance Ad Quality

The rule, quality over quantity, is relevant to many areas, including the optimization of CPM. High-quality ads capture attention and engage viewers, which can lead to a better return on investment. There are mainly two strategies to enhance the quality of your ads.

First, focus on creating compelling visuals and copy. Your ad's design should be visually appealing, professional, and relevant to your target audience. Use high-resolution images or videos that resonate with your audience's interests and needs.

Pair these visuals with clear, concise, and persuasive copy that communicates your value proposition effectively.

Second, make sure your ads are contextually relevant. This involves tailoring your message to fit the platform and placement where the ad will appear.

For example, a more casual tone might work well for social media, while a formal approach could be better suited for professional networks like LinkedIn.

4. Leverage Retargeting

One effective strategy to optimize your CPM is to weave retargeting campaigns into your overall ad strategy. It involves showing ads to individuals who have visited your website, engaged with your content, or shown interest in your products.

To effectively use retargeting, segment your audience based on their behavior and interaction with your brand. For instance, create separate campaigns for users who abandoned their shopping carts, those who visited specific product pages, or those who engaged with your social media posts.

Then, tailor your ads to address the specific interests and needs of each segment. Personalized ads can significantly enhance user engagement and drive higher conversion rates.

5. Ensure a Smooth Mobile Experience

Around 78% of online users access websites and social media platforms through their mobile devices. Hence, it's crucial to ensure that your ads are optimized for mobile.

To do so, use visually appealing images and videos that load quickly and look good on smaller screens. Plus, keep your ad copy concise and to the point, as mobile users tend to have shorter attention spans.

Remember, easy navigation, clear call-to-action buttons, and quick load times are essential for keeping mobile users engaged and encouraging them to complete the desired action.

An example of smooth mobile ad is as follows:
