(A) Apply sitewide tagging of your UET tag (including all ad landing pages)
(C) Don’t place your UET tag within an iFrame
(D) Incorporate all relevant event parameters into your UET tag
(E) All of the above
You should apply sitewide tagging of UET tags because it allows Microsoft to track conversions from any page of that website.
You should not use UET tags in iFrame because your site becomes vulnerable to cross-site attacks. Hackers can change your website URL and put their URL instead.
Put all of your event parameters into the UET tag that you want to track like device type, device version, device software, Browser used, etc.
