How it works

From MaxWeb to attribution in three steps.

  1. Step 01

    Sync MaxWeb revenue

  2. Step 02

    Each MaxWeb payment is matched to the original ad click via persistent visitor identity. Spend pulled from Meta / Google / LinkedIn / TikTok is divided over the matched revenue.

How long does the MaxWeb integration take to set up?
Most teams have MaxWeb flowing into Cometly inside five minutes. The connection uses Webhook, and Cometly auto-maps the standard fields, so no developer is required. Setup is 5 guided steps inside the Events Manager.
Do I need engineering help to connect MaxWeb?
No. We support setup via Webhook, which is approachable for anyone on a marketing team, with no engineers required.
How does Cometly calculate true ROAS from MaxWeb?
Sum of MaxWeb revenue (every payment, refund, expansion) divided by ad spend across Meta / Google / LinkedIn / TikTok, broken down by source, campaign, ad set, and creative. LTV ROAS is also available with 30/60/90/180/365-day windows so you can see payback on cohorts, not just first-touch.
Can I see ROAS by campaign and creative?
Yes. Cometly tags every MaxWeb event with the original campaign, ad set, and creative ID, so ROAS rolls up at any level. Most customers build a "creative ROAS" dashboard that sorts by 90-day LTV. That's where the kill/scale decisions get made.
