# Google Analytics

> Track affiliate traffic with consistent UTM parameters.

Afflo works with Google Analytics out of the box — affiliate links already carry UTM parameters so traffic shows up properly in your GA reports. This page covers how to use that data well.

## What happens by default

Every affiliate link Afflo generates includes UTM parameters:

* `utm_source=afflo` (configurable on the program)
* `utm_medium=affiliate`
* `utm_campaign=<program name>`
* `utm_content=<affiliate id or handle>`

When a shopper clicks, Google Analytics sees these and attributes the session to your affiliate channel.

## Read affiliate traffic in GA

Open your GA property and filter by `source=afflo` (or whatever source you set):

* Compare bounce rate and conversion rate against other channels.
* Break down `utm_content` to see which specific creators drive the most engaged visits.
* Use `utm_campaign` to compare program performance.

## Customize UTMs per program

Each program has its own UTM values in Afflo. Keep them consistent across programs so GA reports stay clean:

* `utm_source` — a single value across all programs (for example, `afflo`)
* `utm_medium` — always `affiliate`
* `utm_campaign` — the program name

## Tips

* Don't shorten affiliate links with third-party shorteners. Shorteners can strip UTMs.
* If you use GA4, set up a custom audience for `source=afflo` so you can retarget engaged shoppers later.
* Cross-check GA's affiliate numbers against Afflo's Link Statistics. GA measures sessions; Afflo measures attributed sales. Both matter.

## Troubleshooting

**Sessions without UTMs.** Usually caused by shortened or rewritten links. Confirm partners share the raw Afflo link.

**Numbers don't match between GA and Afflo.** Expected. GA counts sessions; Afflo counts attributed orders within the program's window.
