Hi @hungpham ,
Thanks for your question. The short answer is that, you don’t specifically need sbjs cookies for WooCommerce to function properly. Those are likely from a third-party service for tracking marketing efforts. If you block them, that tracking may not work as intended, but your WooCommerce store will still operate fine.
To explain further: SBJs cookies are part of a library called Sourcebuster.js, which is used for tracking where your website visitors come from. They collect information about the user’s source, medium, campaign, content, and term with respect to marketing campaigns. This data helps you understand how effective your marketing efforts are by attributing traffic to the correct sources. Blocking SBJs cookies means this source-tracking wouldn’t happen, but it won’t affect your shop’s main functions.
It seems those cookies got onto your site from another source, not directly from WooCommerce. If you’ve added marketing tools or analytics, that could be why you’re seeing them. Hope this helps!
