Tools
Two small tools for the two questions every paid campaign raises: where did this visitor come from, and what did it cost to win a customer.
UTM builder
The UTM builder turns a landing page and a few campaign fields into a tagged URL. It includes utm_id, presets for Google Ads, Meta Ads, LinkedIn, newsletters and X, and it cleans up case and spaces so your reports do not split one campaign into three.
CAC calculator
The customer acquisition cost calculator takes your ad spend, other acquisition costs, new customers and leads. It returns CAC, cost per lead and lead to customer rate, and shows the formula with your numbers.
Where to go next
Tagged links only pay off if something reads them. The guide to UTM tracking and marketing attribution explains how UTMs travel from the click to the conversion.
