You may want to consider using Ad Blocker software on your device. Many website banners are targeted based on past activity on the internet (for example showing you items you have previously seen in online stores) so you may also see fewer gambling adverts if you visit fewer gambling websites over time.
Alternatively, you can change your settings in your browser to turn off personalised Ads. This varies by browser so we would recommend looking this up. For Google Chrome, please see here.
Please note this advice is not comprehensive as social media sites may change their operating policies from time to time. There is also no guarantee that information and settings will be carried over between devices (e.g. shared devices between family members). If you are worried about problem gambling, you may find it appropriate to exclude yourself from gambling directly.
