What is A/B Testing in Ad Monetization?

A/B testing (also known as split testing) is the process of comparing two or more variations of ad placements, formats, or designs to see which performs better. Instead of guessing which ad setup works, you use real user data to make revenue-driven decisions.

Key Metrics in A/B Testing:

• CTR (Click-Through Rate): Measures ad engagement.

• CPM (Cost Per Mille): Shows how much advertisers pay for every 1,000 impressions.

• eCPM (Effective CPM): Overall earnings per 1,000 impressions, accounting for all factors.

• Fill Rate: The percentage of ad requests filled with ads.

By running controlled A/B tests, you can improve these metrics and maximize earnings with Adsterra.

Adsterra Ad Units You Should Test

1. Popunders – High-paying but intrusive; test frequency capping.

2. Social Bar Ads – Engaging and interactive; test different widget types.

3. Native Ads – Non-intrusive; test in-content vs sidebar placement.

4. Interstitial Ads – Test load timing (e.g., between page views vs exit intent).

5. Banner Ads – Standard ad units; test different sizes (300x250, 728x90, 320x50).

Step-by-Step Guide to A/B Testing with Adsterra

Step 1: Define Your Goal

Decide whether you want to improve CPM, CTR, eCPM, or user retention. For example:

• “Increase CTR by 15% for native ads.”

• “Improve fill rate by testing different ad sizes.”

Step 2: Select a Variable to Test

Only test one variable at a time for accurate results. Possible variables:

• Ad placement (above vs below the fold)

• Ad format (Popunder vs Social Bar)

• Ad size (300x250 vs 728x90)

• Frequency capping (once per session vs multiple times)

Step 3: Split Traffic Evenly

Divide your audience into two equal groups:

• Group A (Control): Current ad setup.

• Group B (Variation): New ad setup.

Example: If testing banner size, Group A sees 300x250 banners while Group B sees 728x90 banners.

Step 4: Run the Test for Enough Time

Run each test for at least 7–14 days to gather statistically significant data. Testing too short may give misleading results.

Step 5: Measure Performance

Use Adsterra’s reporting dashboard to compare:

• Impressions

• CTR

• CPM/eCPM

• Bounce rate and session time (to track user experience).

Step 6: Apply the Winner & Iterate

Once you identify the winning variation, apply it permanently. Then start testing another variable. A/B testing is an ongoing cycle—not a one-time setup.

Pro Tips for Successful A/B Testing

1. Never Test Multiple Variables at Once – Keep it simple and test one change at a time.

2. Segment by Device and GEO – What works on desktop US traffic may not work on mobile India traffic.

3. Monitor User Behavior – Use Google Analytics alongside Adsterra reports to track bounce rates and retention.

4. Avoid Ad Overload – More ads don’t always mean more revenue; test balance between monetization and experience.

5. Repeat Regularly – Ad performance changes with trends and advertiser demand, so run new tests quarterly.
