The most likely reason you're seeing French YouTube ads is because ads are primarily targeted based on your geographic location, not your account's language settings.
Location-Based Advertising
YouTube and Google Ads use your IP address and other location data to determine the most relevant ads for you. This means that even if your YouTube account is set to English, if YouTube believes you are located in a French-speaking region, you will likely see ads in French.
Common Scenarios
Here are a few scenarios where this might happen:
- Living Near a French-Speaking Border: If you live near the border of a country or region where French is widely spoken (e.g., Canada, Belgium, Switzerland, France), the system may misinterpret your location and serve you French ads.
- VPN Usage: Using a VPN (Virtual Private Network) that connects to a server in a French-speaking country will almost certainly result in French ads.
- Inaccurate Location Data: Occasionally, location services can be inaccurate. Your IP address might be incorrectly associated with a location in a French-speaking area.
- Travel: If you recently traveled to a French-speaking region, your location data may still be reflecting that previous location.
How to Potentially Reduce French Ads
While you can't entirely eliminate ads based on location, here are some steps you can take:
-
Check Your Google Account Location:
- Go to your Google Account settings.
- Look for "Personal info."
- Find "Address" and make sure your home address is accurate. This helps Google refine location-based services.
-
Disable Location Services (With Caution): You can disable location services on your device or within your Google account, but this may impact other location-dependent apps and services. To do this:
- On Android: Go to Settings > Location and toggle it off.
- On iOS: Go to Settings > Privacy > Location Services and toggle it off.
- In Your Google Account: Go to your Google Account Activity Controls and pause "Web & App Activity" and "Location History."
-
Review Ad Personalization Settings: You can influence the types of ads you see by reviewing and adjusting your ad personalization settings in your Google Account. This won't directly prevent location-based targeting, but it might shift the types of products and services advertised, even if the language remains French. Go to Google's Ad Settings to manage this.
-
Clear Browser Cache and Cookies: Sometimes, old cookies and cached data can interfere with location detection. Clearing these might help.
Summary
While language settings are important for YouTube's interface and video recommendations, ad targeting relies heavily on location. If you're seeing French ads, your location data is likely being interpreted as being in or near a French-speaking region. Try the troubleshooting steps to potentially mitigate this.
