Keep your embeds on your own website

By default, anyone who copies your embed code can show it on their site. To allow only your own websites:

1. Go to Settings → Developers → Embeds.
2. Under Where your embeds can appear, enter your websites, one per line:

mysite.com
www.mysite.com
*.mysite.com

3. Click Save websites.

*.mysite.com covers every subdomain (like shop.mysite.com), but not mysite.com itself, so list both if you use both.

Browsers then refuse to show your embeds anywhere else. To allow any website again, empty the box and save.

Your Paylead store, product pages and links aren't affected: this only applies to embeds on other websites.
