A/B Test Your Links to Find What Converts

A/B testing in Brevr splits your link’s traffic across two or more destination URLs so you can measure which page performs better. One link, multiple destinations, real data to guide your decision.

What You’ll Learn

  • How Brevr’s traffic split works
  • How to set up an A/B test on any link
  • How to read your results and declare a winner

How A/B Testing Works

Brevr randomly assigns each visitor to a variant based on the percentage weights you set. A visitor clicking your link has a 50% chance of landing on Variant A and a 50% chance of landing on Variant B — or whatever split you define.

The split is random on every click. Brevr does not remember which variant a returning visitor previously saw. All your variant percentages must add up to exactly 100% before you can save the link. Brevr enforces this so no traffic is lost.

How to Set Up an A/B Test

  1. Open your link in the Brevr link editor.
  2. Navigate to the Smart Routing section.
  3. Click “Add Rule” and select “A/B Test” as the rule type.
  4. Enter the destination URL for Variant A (your control page).
  5. Set the traffic percentage for Variant A — for example, 50%.
  6. Click “Add Variant” to add Variant B.
  7. Enter the destination URL for Variant B and set its percentage.
  8. Repeat for any additional variants. All percentages must sum to 100%.
  9. Save the link. Brevr immediately begins splitting traffic.

Example: Two-Variant Test

A typical A/B test compares your existing page against a new version:

VariantDestination URLTraffic Split
A (Control)/landing-page-original50%
B (Variant)/landing-page-new50%

Run this test long enough to collect statistically significant clicks — typically at least a few hundred per variant. Then compare your conversion metrics in your analytics tool and pick a winner.

Reading Your A/B Test Results

Brevr tracks how many clicks each variant receives. Find your results in the link’s analytics panel.

Navigate to your link in the Brevr dashboard and click “Analytics.” Under the Smart Routing section, you will see a breakdown of clicks per variant with the percentage of total traffic each variant received.

Use these numbers alongside your conversion data from your landing page analytics tool. Brevr tells you how many people reached each page — your landing page tool tells you how many of those people converted.

Declaring a Winner

Once you have enough data to make a decision, consolidate your link to the winning variant.

  1. Open the link editor for your tested link.
  2. Navigate to the Smart Routing section.
  3. Delete the losing variant by clicking the remove icon next to it.
  4. Set the winning URL as your default URL, or adjust the remaining variant to 100%.
  5. Save the link.

All future traffic goes to the winning page. Your click history stays in analytics so you can always reference the original test results.

Plan Limits

The number of variants you can add to a single A/B test depends on your Brevr plan:

PlanMax Variants per Link
Free2 variants
ProUnlimited
BusinessUnlimited

Free plan users can still run meaningful 50/50 tests. Upgrade to Pro or Business if you want to test three or more variants simultaneously.

Frequently Asked Questions

Do all variant percentages have to add up to 100%?

Yes. Brevr will not let you save the link unless your variant percentages total exactly 100%. This prevents any traffic from being unaccounted for.

Does Brevr remember which variant a visitor saw before?

No. Each click is assigned a variant independently at random. Brevr does not use cookies to maintain consistency for returning visitors. If consistent assignment matters for your test, track variant exposure in your landing page tool.

Can I run an A/B test alongside country or device targeting?

Yes. You can stack an A/B test with country or device targeting on the same link. For example, you could target US visitors with a country rule and run an A/B test for all other visitors on the same link.

How long should I run my A/B test?

Run your test until each variant has received enough clicks to draw a reliable conclusion — typically a minimum of a few hundred clicks per variant, and ideally over a full week to account for day-of-week variation in traffic patterns.

What happens to my analytics data when I delete a losing variant?

Your historical click data for that variant remains in analytics. Deleting the variant stops future traffic from going to that URL — it does not erase past records.

Can I change the traffic split while a test is running?

Yes. Edit the link and adjust the percentages at any time. Changes take effect immediately for all new clicks. Keep in mind that adjusting a live test mid-way can affect the statistical validity of your results.

Step 2: Configure Variant A

Enter the destination URL for Variant A — your control page — and set its traffic percentage. For a standard even split, enter 50%.

📸 Screenshot: [Variant A row with a destination URL filled in and the percentage field set to 50]

Step 3: Add and Configure Variant B

Click “Add Variant,” enter the destination URL for Variant B — your challenger page — and set its percentage so the two variants sum to 100%.

📸 Screenshot: [Both Variant A and Variant B rows visible, each with a destination URL and 50% traffic weight, with the total shown as 100%]

Click Save. Brevr immediately starts splitting traffic between the two variants at random on every click. Let the test run until each variant accumulates enough clicks to draw a reliable conclusion.

Step 5: Read the Results in Analytics

Navigate to the link in the Brevr dashboard and click “Analytics.” The Smart Routing section shows click counts and traffic percentages for each variant side by side.

Step 6: Declare a Winner

Once you have enough data, open the link editor, delete the losing variant, set the winning URL to 100%, and save. All future traffic goes to the winner while the original test data remains in analytics.
