| Example product review | Setup took just a few seconds, and it works right away. All my pixels from GTM are now server-side and perfectly connected. So much money saved on ads. | "It's disheartening to hear about the app developer's refusal to enable enhanced conversion tracking without additional charges... It almost seems like price gouging for Shopify merchants to compensate for losses from the BigCommerce side." | "We were having difficulties with accurate and consistent revenue attribution...With Littledata implemented, we now get consistent and accurate revenue attribution." |
| Example support review | The support was very fast to answer our questions and super helpful. Just be careful to check that the events don't trigger twice. | "Customer support is non-existent, and responses take forever... very frustrating experience overall." | "Customer support is absolutely amazing... you can never go wrong when an app does what it says and tacks on great service!" |
