What is Cometly?
Cometly is an ad attribution and analytics platform that tracks customer journeys across Meta, Google, TikTok, and other paid channels. It uses first-party data and server-side tracking to provide accurate ROAS and attribution beyond what native ad platforms report. Pricing starts at $199/month with higher tiers for more ad spend. It serves DTC brands running significant paid media budgets.
Where Cometly Falls Short
Attribution Platform, Not Revenue Architecture
Cometly maps which ads and touchpoints drive conversions. It does not create bundle flows, tiered discounts, or offer stacks. Knowing which ad works does not change what the customer puts in the cart.
No Bundle Builder or Cart-Level Incentives
Cometly tracks ad performance and customer journeys. It cannot build mix-and-match bundles, free shipping thresholds, or combined discount + shipping + gift rewards that lift AOV.
$199/Month Minimum for Attribution Data
Cometly starts at $199/month. That is 4x Tiergain Pro. Cometly helps allocate ad budget smarter. Tiergain generates revenue from every order. One is a cost of doing paid media. The other is a profit center.
Value Limited to Paid Media Merchants
Cometly delivers ROI only for stores running paid ads. Merchants relying on organic traffic, SEO, or email get minimal value. Tiergain lifts AOV regardless of traffic source - paid, organic, direct, or referral.
Attribution Does Not Change Offer Quality
Cometly can show you that Meta drives 60% of revenue. It cannot fix the $34 AOV those Meta visitors produce. Tiergain lifts that $34 to $48 through bundle architecture. Better offers improve ROAS more than better attribution.
