I'm using Wordfence - HandL UTM Grabber Guide

UTM attribution overview

This guide explains I'm using Wordfence - HandL UTM Grabber Guide. It helps you capture UTM source, medium, campaign, term, content, click IDs, referrer, and landing page data and keep the marketing context needed for accurate reporting across forms, bookings, signups, and sales.

Wordfence has a feature called Live Traffic that serves an extra blank pageview to every new(?) visitor to check if they are a bot or real traffic.It is reported by our clients that HandL UTM Grabber must have been picking up the wordfence pageview as the first pageview as handl_url.

Proposed Solution: Turn off Live Traffic (switched from ALL to Security Only)
