Randomly rotate traffic across multiple destination URLs based on percentage weights. Get a ready-to-paste JavaScript snippet in seconds.
What Is a Link Rotator?
A link rotator is a script that distributes incoming traffic across multiple destination URLs based on defined percentage weights. Instead of sending 100% of your visitors to one page, you can send 60% to Offer A, 30% to Offer B, and 10% to Offer C — all from the same entry point URL.
Unlike enterprise split-testing platforms that charge monthly fees, this tool generates a lightweight JavaScript snippet that runs entirely in the visitor's browser — no server required, no monthly cost, no tracking dashboard login.
How It Works
Paste the generated snippet into the <head> of your entry page HTML. When a visitor lands on the page, the script generates a random decimal number between 0 and 1, then checks it against the cumulative weight thresholds you defined. The browser is immediately redirected before any visible content renders — the experience is seamless.
Best Use Cases for a Link Rotator
- Affiliate Marketing Split Testing: Rotate traffic across competing offers to discover which converts best before committing your full media budget.
- Multi-Offer Campaigns: Run multiple affiliate offer variants simultaneously, distributing traffic proportionally based on commission rates or EPC performance.
- Geographic or Demographic Segmentation: Combine with country-based redirect logic to send specific segments to tailored landing pages.
- Load Balancing: Spread visitors evenly across multiple hosted versions of a high-traffic page to distribute server load.
- Offer Fallback Chains: Send the majority to your primary offer but redirect a small percentage to a backup offer in case the primary goes out of stock or pauses.
Percentage Weights Must Total 100%
The combined percentages of all URLs must add up to exactly 100% for the rotator to work correctly. The tool validates this for you and shows an error if the weights do not balance. Adjust sliders until the total reads "100%" in green before generating the snippet.
Frequently Asked Questions
Is the traffic distribution exactly random?
Yes, but probabilistically. The script uses Math.random() which is pseudo-random, meaning the distribution will approach your defined percentages over a large volume of visits but may deviate slightly on smaller sample sizes. Over thousands of visits, the split will be statistically accurate.
Can I track where each visitor went?
Not automatically with this snippet. To track conversions per variant, add UTM parameters to each destination URL before entering them here. Your analytics platform (Google Analytics, etc.) will then attribute conversions by UTM campaign/content tags correctly.
How many URLs can I rotate between?
This tool supports up to 5 destination URLs. For more complex rotations, the generated snippet code can be manually extended by duplicating the weight-check logic for additional URLs.
