Step-by-Step Guide to KPI Analysis
1. Identify and Set Up KPIs
Before you start analyzing your KPIs, you need to ensure that you are tracking the right metrics for your campaign. These include basic KPIs such as reach, impressions, clicks, and cost per result. For Facebook Ads, one of the most common platforms, you can view the prepared data in one central location.

2. Understand Basic Metrics
Now it’s time to understand the key metrics. Reach shows you how many people have seen your ad, while impressions represent the total number of views. Use these values to assess the visibility of your advertising.
3. CTR and Its Importance
The Click-Through Rate (CTR) is a decisive factor. It indicates the ratio of clicks to impressions. A CTR of 1 % or less may suggest that your ads are not relevant or engaging enough. In most industries, the CTR should be between 2 and 5 % to be considered successful.

4. Analyze Quality Score
The Quality Score of Google Ads is a complex yet decisive measure of success. It consists of the relevance of your ad, the keywords, and the landing page. Each element must be optimally designed to improve the efficiency of your campaign.

5. Monitor Cost per Click (CPC)
The CPC indicates how much you pay on average for each click. A low CPC with high relevant reach is a good sign that your campaign is working efficiently. Keep in mind the keyword strategy, as longer keywords often have lower costs.
6. Measure Conversion Rate
The conversion rate is another important metric that indicates how many of the clicks actually lead to a desired action (e.g., purchase, registration). Ensure you aim for a target of 1 to 3 % for high-priced products, while 2 to 5 % is realistic for cheaper products.
7. Evaluate Cost per Acquisition (CPA)
This metric quantifies how much it costs to acquire a new customer. To determine an accurate CPA, consider all relevant marketing costs. A CPA that is below your revenue indicates that your campaign is profitable.
8. Analyze Return on Ad Spend (ROAS)
Measure the revenue each of your campaigns generates in relation to the expenses. A ROAS of over 2 indicates that you are generating more revenue than costs, which is a positive sign. Set yourself the goal of constantly increasing this value.
9. Monitor Keyword Performance
Analyze the performance of your keywords in Google Ads. Identify keywords that generate high clicks but low conversions, and adjust your strategy if necessary. Over time, the performance of your keywords will also influence the efficiency of your entire campaign.
10. Use Formulas to Calculate KPIs
To make handling KPIs easier, you can use various formulas:
- Click-Through Rate (CTR): Clicks / Impressions * 100
- Conversion Rate: Conversions / Clicks * 100
- Cost per Click (CPC): Total campaign costs / Number of clicks
Summary – KPIs in the Marketing Analysis Process
A comprehensive analysis of KPIs is crucial for the success of your Paid Ads campaigns. By following the steps outlined above, you can ensure that you keep track of all necessary metrics and make strategic adjustments to continuously optimize your campaigns.
