## The Power of Localization
Localization is more than just a translation; it is a strategic tool designed to increase your ROI. When an affiliate in **Germany**, **Spain**, or **Brazil** logs into their dashboard and sees data in their native language, it removes friction and builds immediate trust. By speaking your affiliates' language, you empower them to focus on what they do best: promoting your brand.
##### The Impact of Localization on Your Bottom Line
Providing a localized portal leads to better engagement, fewer support tickets, and ultimately, a more successful partnership. By giving your affiliates a dashboard they fully understand, you allow them to focus on driving sales rather than navigating technical hurdles.\
The statistics speak for themselves:
* **Boost Conversion Rates:** Localized interfaces can increase conversion rates by up to **70%**.
* **Drive More Sales:** Programs with localized support see a sales increase of **40% to 50%** on average.
* **Build Global Trust:** **72% of users** are more likely to engage and convert when information is presented in their native language.
***
## Supported Languages
To help you cater to a global audience, the **Affiliate Portal** is currently offered in the following languages:
* **English**
* **French**
* **German**
* **Spanish**
* **(Brazilian) Portuguese**
## Custom Language Requests
Need a language that isn't on our list yet? We are committed to your growth. If you require a specific language for your affiliate or advertiser portal and are ready to invest in its implementation, **contact our support team**. We view our customers' success as our own and are happy to discuss custom development to meet your global needs.
***
## Plan Availability & Access
The multi-language feature is structured to grow with your business:
* **Scale & Enterprise Plans:** Full access to all supported languages is included by default.
* **Launch Plan:** This feature is not included. To use it, upgrade to the Scale plan from Billing > Change plan (see [Changing Your Subscription Plan](https://support.tapfiliate.com/getting-started/essential-account-settings/changing-your-subscription-plan.md)).

## How to Set Up Your Program Language
You can define the default language for each of your programs individually.
1. Log in to your **Advertiser Dashboard**.
2. Navigate to **Programs** and select the specific program you want to edit.
3. Click on the **Signup page** tab in the side menu.
4. Find the **Language** dropdown (as seen in the screenshot below).
5. Select your preferred language and save.
***
## How It Works: Advertiser vs. Affiliate Side
Understanding the difference between the **Signup Page** and the **Internal Portal** is key:
* **The Signup Page:** The language you set in the "Signup page" settings is fixed for all visitors. **Affiliates cannot change the language of the signup form.** They will see it exactly as you have configured it.
* **Inside the Affiliate Portal:**
**On the Launch Plan:** Your affiliates will see their dashboard only in the default language you selected (e.g., if you choose English, their entire portal remains in English).\
**On Scale/Enterprise Plans:** Once logged in, affiliates have the freedom to change their personal dashboard language. They can do this by clicking their profile icon and going to **Profile Settings**.
* **The Admin Side:** Please note that the Advertiser (Admin) platform interface is currently available in **English and Spanish only**.
## FAQ
### ❓What languages are currently supported?
The affiliate portal currently supports English, French, German, Spanish, and (Brazilian) Portuguese.
### ❓Can I have different languages for different programs?
Yes! Since language is set at the program level (**Programs > Signup page**), you can have one program in Spanish and another in German within the same account.
### ❓What happens if an affiliate wants a language I haven't enabled?
On Scale/Enterprise plans, the affiliate can choose from any of our supported languages within their own settings. If you need a language outside of our current list, see the Custom Language Requests section above.
### ❓Why can't I see the language settings in my account?
If you are on the **Launch** plan, these settings are not available. Upgrade to the Scale plan to unlock them (see [Changing Your Subscription Plan](https://support.tapfiliate.com/getting-started/essential-account-settings/changing-your-subscription-plan.md)).
