Tag your links
Add utm_source, utm_medium and utm_campaign so Modovisa can group visitors and purchases under a campaign name.
Why tagging matters
A tagged link tells Modovisa where the click came from, what kind of link it was, and the campaign name. Without those, Performance has nothing to group. A Google click id (gclid) alone is not a campaign name.
Purchases and conversions
Sales show up when the thank-you page sends a purchase event with purchase_amount, or when a store integration already recognises the confirmation page.
