You can add manual tags to the destination URL of any campaign link that you want to track. Tags aren’t technically required for any campaign, but if you intend on tracking traffic and performance, you should use UTM parameters on your links for email campaigns, social media campaigns, ad campaigns, and more. Manual tags will give you more detailed tracking than auto-tagging. Remember, Source, Medium, and Campaign are required parameters for UTM code, but Term and Content are optional.
