What store owners complain about in attribution tools

How to read this

• Disclosure: Causality Engine sells a €99 read that competes with the tools named here. We chose which complaints to collect, so this page shows what went wrong for some buyers, not how most buyers rate a tool.
• The number of quotes per theme reflects what we found and checked, not how common each complaint is. Most of these tools score well overall; their published ratings are in the table at the end.
• Quotes are the reviewers’ own words, 35 words or fewer, checked word for word against the page on 4 November 2026. We give the platform, country and date, never names or handles. Trustpilot does not verify that reviewers were customers.
