Force Traffic to a Specific Test Variation (Ad-Level Control)

Why You’d Want to Do This

 

In some cases, you may want specific ads to always send traffic to a specific test variation instead of letting traffic rotate naturally.

 

Common reasons include:

 

• You’re running different ad messages that align with different page versions
• Each variation is tied to a different optimization goal in the ad platform
• You want full control over which experience an ad delivers
• You’re validating a hypothesis before rolling traffic evenly

 

Regardless of the reason, Visiopt makes this easy and fully trackable.

 

How It Works

 

Visiopt allows you to force traffic to a specific test variation by adding a simple parameter to the end of the URL.This ensures that anyone clicking that link will always see the same variation.

 

How to Force a Variation:

 

To force visitors to load a specific variation, add the following parameter to the URL:

?_vt_vart=#

Replace # with the variation number you want to send traffic to.

 

Examples:

Control (Variation 1):

?_vt_vart=1

 

Variation 4 would be:

?_vt_vart=4

 

Variation 11 would be:

?_vt_vart=11

 

Example full URL:

https://testpage.com?_vt_vart=2

 

Anyone visiting this URL will always see Variation 2.

 

Important Notes:

 

The number at the end of the parameter must match the variation number inside the test

 

Best Practice:

 

Use forced variations only when you need control at the ad or traffic-source level.  For learning and discovery, allow Visiopt to rotate traffic normally.
