Target Weight and Traffic Distribution

Target weights control how traffic is distributed across multiple targets in weighted rotation algorithms.

Understanding Weights

Weight is a numeric value (0-100) that determines what percentage of traffic each target receives. A weight of 0 effectively pauses the target (same as setting status to paused).

The formula:

Target Traffic % = (Target Weight ÷ Total Weight) × 100

Weight Examples

Example 1: Equal Split

1. Target A: Weight 50 (50/100 = 50%)
2. Target B: Weight 50 (50/100 = 50%)

Example 2: Equal Split 2

1. Target A: Weight 100 (100/200 = 50%)
2. Target B: Weight 100 (100/200 = 50%)

Example 3: Unequal Split

1. Target A: Weight 100 (100/150 = 66.7%)
2. Target B: Weight 50 (50/150 = 33.3%)

Example 4: Three-Way Split

1. Target A: Weight 50 (50/150 = 33.3%)
2. Target B: Weight 50 (50/150 = 33.3%)
3. Target C: Weight 50 (50/150 = 33.3%)

Changing Weights

To adjust traffic distribution:

1. Edit the link
2. Edit each target you want to modify
3. Change the weight value
4. Save each target

Changes take effect immediately for all new clicks.

Weight Best Practices

Use Round Numbers

Weights of 100, 200, 300 are easier to understand than 137, 284, 419. The actual numbers don't matter, only the ratio.

Start Equal

Begin split tests with equal weights. Adjust based on performance data after collecting sufficient clicks.

Don't Micromanage

Small weight differences (like 100 vs 105) won't produce meaningful distribution changes. Make significant adjustments.

Consider Statistical Significance

Wait for at least 100-200 clicks per target before adjusting weights based on performance.

When Weights Don't Apply

Weights only affect these rotation algorithms:

1. Weighted Random
2. Only Uniques

Weights are ignored in:

1. Sequential (uses order, not weights)
2. Sequential Unique (uses order, not weights)
3. Progressive Exposure (uses configured progression)

Advanced Topics

Dynamic Weight Optimization

Monitor conversion rates and adjust weights to send more traffic to better-performing targets while keeping losing variants in rotation for continued testing.

Weight and Geo-Filtering

When using geo-filtering, weights only apply to eligible targets for each visitor. If only one target matches a visitor geo-filter, that target receives 100% regardless of weight.

Weight Limits

Weight values range from 0 to 100. A weight of 0 effectively pauses the target without changing its status. Large differences (e.g., 5 vs 100) can make targets with low weights receive very little traffic.
