Page URL tracking - Track all leads visiting a page under a single campaign. Use for blog posts and website pages.
Referring URL tracking - Track all leads visiting from a particular URL under a single campaign. Use for affiliate tracking only (very rarely used) or use when you want to track all referrals from a social media platform like Facebook or LinkedIn. This will track both clicks on posts and any links to a trackable page.
UTM tracking - The most accurate tracking method. Place a string of text at the end of your links before posting. Use for all externally posted campaign links (paid ads, social media, guest post, etc).
Track via automation - Tracking is created in the visual workflow. Use for special implementations or integrations.
