1. ROI (Return on Investment)
ROI, or Return on Investment, indicates how effectively your funds are being invested in a campaign. It’s one of the most crucial metrics, as it helps affiliates determine whether a campaign is profitable. The formula for calculating ROI is:
ROI = (Revenue — Costs) / Costs × 100%
The higher your ROI, the more profitable your campaign is.
2. CR (Conversion Rate)
Conversion Rate (CR) measures the percentage of visitors who complete a desired action, such as making a purchase, registering, subscribing, or filling out a form. The formula for calculating CR is simple:
CR = Number of Conversions / Total Visitors × 100%
This metric is essential for evaluating how well your site or landing page converts traffic into leads.
3. Inst2Reg and Reg2Dep
Inst2Reg and Reg2Dep are metrics often used in the gambling industry. Inst2Reg reflects the percentage of users who, after installing an app, proceed to register, while Reg2Dep shows how many of those registered go on to make a deposit.
- Inst2Reg = Installs / Registrations × 100%
- Reg2Dep = Registrations / Deposits × 100%
These metrics help assess the effectiveness of an offer and how well your traffic converts into actual revenue.
4. CTR (Click-Through Rate)
CTR measures how frequently users click on your ads compared to how many times the ad is shown. It’s a key indicator of how engaging and relevant your ad creatives are.
CTR = Number of Clicks / Number of Impressions × 100%
A higher CTR indicates that your ads are appealing to the audience.
5. EPC (Earnings Per Click)
EPC shows the average earnings generated from each click on your ads. This metric is crucial for determining the profitability of your campaign.
EPC = Total Earnings / Total Clicks
The higher your EPC, the more profitable your advertising campaign is.
6. ARPU (Average Revenue Per User)
ARPU indicates the average revenue generated per user, helping you understand the profitability of your user base.
ARPU = Total Revenue / Total Number of Users
This metric allows affiliates to evaluate how much value each user contributes to their overall revenue.
7. AR (Approval Rate)
Approval Rate (AR) reflects the percentage of confirmed conversions out of the total number of conversions.
AR = Approved Conversions / Total Conversions × 100%
This metric helps you understand how many conversions were verified and paid by the advertiser.
8. CPM (Cost Per Thousand Impressions)
CPM (Cost Per Mille) measures the cost of showing your ad 1,000 times. This metric is especially useful for brand awareness campaigns where you pay for exposure rather than direct clicks or conversions. It is calculated as follows:
CPM = (Total Advertising Cost / Number of Impressions) × 1,000
A lower CPM can indicate more cost-effective advertising if you’re getting good visibility and engagement.
9. CPC (Cost Per Click)
CPC (Cost Per Click) reflects the price you pay for each click on your ad. This metric is crucial in paid advertising models, where advertisers are charged based on clicks rather than impressions or conversions. The formula is:
CPC = Total Advertising Cost / Number of Clicks
A lower CPC means you are getting more clicks for your budget, which can help you drive traffic and conversions more efficiently.
Conclusion
In this article, we covered key affiliate marketing metrics such as ROI, CR, CTR, EPC, ARPU, CPM, and CPC. These indicators provide insights into the effectiveness of your campaigns and help you adjust your strategy for maximum profitability. Remember to analyze these metrics together rather than in isolation to get a comprehensive understanding of your campaign’s success. Use these metrics to optimize your marketing efforts and achieve your desired goals.
