About Littledata ‑ The Data Layer

Littledata is the customisable data layer built for Shopify stores. We recover revenue, audiences, and conversions that tag-based tracking misses, and send clean, first-party signals to Google Analytics, Google Ads, Meta Ads, Klaviyo, TikTok, and Pinterest. This gives merchants a more accurate view of what's actually driving sales, so ad platforms and email tools can make better decisions with more complete data.

Great App, backed by exceptional technical customer service
— Office Supermarket
Regardless your marketing budget size, you will have much better results using server-side tracking. And with Littledata, you skip the 99 mind boggling steps of setting this up correctly for ecommerce. It just works. Support and knowledge centre is great. Highly recommend.
— OZO Keyboards
Getting started with LittleData has been a breeze. Great support, great guides, and the app's usability is excellent.
— Grøndals
The app is amazing! Their price - value ratio is incredible good, installation is so easy which is what got my attention to begin with. Also I can confirm my EMQ has increased considerably since installing the app, they also have their own bot filtering feature in-app, AND their customer support could not be any better they respond super fast the same day via live-chat, something very rare nowaday...

Ottima applicazione, tracciamento reale degli eventi e assistenza clienti top, la consiglio vivamente

Support is very helpful for any setup questions or issues.

Customer support is outstanding! They have helped us with installation, configuration and a lot of other questions regarding the app and data. /anna

I can't say enough how great this app is - and the team that supports it. i paid for the connection audit to start things off - and the team walked me through connected everything correctly - I'm so glad I did it. Following that, they've communicated with me regularly to ensure I'm utilizing the app to the fullest. Very excited to see what this app can do for our site!
— The Sensory Supply
Working with Littledata has been a pleasure. The application has fixed our leaky funnel capture set up and solved a real pain point for us. The platform continues to ship improvements and updates every month, further upgrading our ability to capture multi-touch attribution. Our success manager, Cornelia deserves a special shout out for her willingness to jump in and work with our specific set up...
— Silver Oak Cellars
Littledata's customer service has been second to none. They have helped me several times.
— DS18
Cornelia found and fixed a real issue in my tracking setup that was costing me money. We had duplicate events firing between server-side and browser tracking. She spotted it immediately and cleaned it up. She knew exactly what she was looking at and handled it quickly. Now the data is clean and consistent. That’s what matters. Thank you.

We have been working with Little Data for a couple of years and are satisfied with the service. Communication with customer support is smooth: they respond quickly and are always happy to help.
— Noordcode
Connecting Littledata – The Data Layer was straightforward, and the initial setup was quick with no obvious issues. Unfortunately, that's where the positives ended. We expected a complete e-commerce integration with Google Ads, but only three conversion events were available: Purchase, New Customer Purchase, and Existing Customer Purchase. Essential e-commerce events such as add_to_cart, begin_ch...

Tried this app for a month, saw zero improvement in CAC, so uninstalled. After uninstalling it left weird code under "Additional details __ld_attr" very long sequence of numbers and letter. I reached out to LittleData for support and they said it was from previous orders/visits of the customer, however these are NEW customers it is showing on. I reached out again and they haven't responded or...
— eFlow Nutrition
I'll describe the situation, and you decide whether it's worth it. I tested on a single Google Ads channel with almost 100% of orders qualified for that channel. The result: a little over 50% of conversions were not counted. This is a disaster. It already affected campaign optimization and the campaign results (Performance Max), and I also paid almost $23 for this super tracking. I strongly discou...
— Nid Magique
Two of our Shopify stores were using Littledata, but one of them has been experiencing ongoing issues with Facebook CAPI and Pixel, where Littledata fails to pass the fbc and fbp parameters to our Facebook Pixel. Despite seeking support for over two weeks and reaching out multiple times, the support team repeatedly assured us that the issue had been resolved or would be fixed soon. However, the er...
— Hangersforless
Absolutely terrible customer service. Reached out to them 6 hours ago and still have not heard anything back. Their app broke our site and they will not respond.
— Revo Sunglasses
Littledata did entirely fix the missing transactions issue for us. However, whilst doing that, it completely skewed the attribution of our CPC & Organic traffic - something we couldn’t accept as it made our Ads reporting even worse, which was the whole reason we installed. I am understanding of apps not always working perfectly but when I reached out to the support team, they totally gaslit me -...

Be careful. I've had a very bad experience with Littledata Tracking (GA4). Zero benefit. Money wasted as if they were the ones who invented GPT or the whole internet in general. Their goal is to take money, not to help you make money
— EcoTinySteps
Their customer service basically doesn't understand any technology, I asked them to help me install google purchase events, but they basically couldn't provide any help. I wasted almost a month on this app and got nothing. Sales fell sharply. It is not recommended to use this app, it is a huge trap
