ProfitMetrics focuses on profit-based marketing analytics (POAS® tracking), making it ideal for optimizing ad spend by profitability rather than revenue. It pulls data directly from Shopify's servers, ensuring reliable tracking. However, it lacks identity resolution capabilities.

Retention.com specializes in identity resolution to recover lost shoppers and boost Klaviyo audiences, but does not pull directly from Shopify's servers, limiting its ability to enrich events with customer data or capture server-side events the browser misses.

Where Littledata wins over both: Neither is Littledata, so here's where Littledata stands out:

  • Direct from Shopify's servers — unlike Retention.com, Littledata captures complete customer journey data including checkout steps browsers can't see
  • Identity resolution — matches Retention.com's audience-building capability
  • 30-day free trial + zero-code setup — faster, lower-risk implementation than both
  • Natively supports Shopify Markets — critical for international Shopify Plus operations
  • Fully automatic tracking — no ongoing maintenance required

Example product review"I waited another two weeks. Nothing. Only replies when I followed up myself. After about a month and a half of waiting in their support queue, I’d had enough. I uninstalled the app and removed all their scripts… but even now, I still see their script showing up in my orders.""We were having difficulties with accurate and consistent revenue attribution...With Littledata implemented, we now get consistent and accurate revenue attribution."
Example support review"Very complicated app, poor support – a frustrating experience... completely unprofessional, overly complicated, and really poor communication.""Unfortunately, the team... very high employee turnover; it can be really frustrating to have to re-explain things to new reps.""Customer support is absolutely amazing... you can never go wrong when an app does what it says and tacks on great service!"

ProfitMetrics focuses on sending profit-based data (not just revenue) to ad platforms — so Google Analytics, Meta Ads, and Google Ads receive contribution margin metrics, enabling profit-optimized bidding rather than revenue-based optimization.

Retention.com sends identity-resolved visitor data to Klaviyo — its core value is identifying anonymous site visitors and syncing them as profiles/events for email/SMS retargeting flows.

Littledata is a broad server-side data pipeline focused on accurate event tracking across the widest destination range (analytics, paid media, CDPs, and owned marketing channels), prioritizing data completeness and attribution accuracy rather than profit metrics or identity resolution.

In short: ProfitMetrics = profit data for ads; Retention.com = visitor identification for CRM; Littledata = accurate event data everywhere.

How does ProfitMetrics work?

ProfitMetrics computes gross profit per order (revenue less discounts, COGS, shipping, payment fees and packaging, ex-VAT) and pushes that figure to ad platforms as the conversion value, so smart bidding optimises on margin rather than revenue.

Does ProfitMetrics work with Shopify?

Yes, ProfitMetrics is installed on 400 Shopify sites according to the latest stats from BuiltWith.

How does Retention.com work?

Retention Grow uses a large third-party list of email addresses to link anonymous sessions to emails given to a third party brand. This can grow your marketing audience, but at the expense of higher spam and privacy complaints.

Yes, Retention.com is installed on 1,950 Shopify sites according to the latest stats from BuiltWith.

When is ProfitMetrics a better choice than Littledata?

ProfitMetrics is a better choice if you want to bid on profit rather than revenue and have the COGS, shipping and payment-fee data to feed it — especially on Magento, Lightspeed or a custom cart rather than Shopify. Littledata is the better fit for teams who want turnkey, fully managed server-side tracking without building or maintaining tag infrastructure.

When is Retention.com a better choice than Littledata?

Retention.com is a better choice if your goal is de-anonymising website traffic into contactable emails to grow owned email and SMS remarketing. Littledata is the better fit for teams who want turnkey, fully managed server-side tracking without building or maintaining tag infrastructure.

How is Littledata's tracking different from Google Tag Manager?

Littledata sends purchase and behavioural data server-to-server, directly from Shopify's servers, so it does not depend on browser tags or a Google Tag Manager container you have to maintain. Tracking keeps working when Shopify changes the checkout, and events can be enriched with customer and order data the browser never sees. Tools built on server-side Google Tag Manager still rely on browser tags to collect events, and someone has to build and maintain the container.

Do I need an implementation agency to set up Littledata?

No. Littledata is turnkey: install the Shopify app and server-side tracking is live, with no code and no Google Tag Manager required. Self-managed server-side setups typically need 10 to 40 hours of specialist configuration up front, plus a few hours a month of ongoing maintenance, which is why a low sticker price often hides a much higher true cost.

How does Littledata handle event editing?

Littledata's Event Editor lets you customise and enrich the events sent to each destination without code, so you control exactly what data reaches Google Analytics, Meta, Klaviyo and your other marketing tools.

What is Littledata's Profit signal?

Littledata's Profit signal sends true profit, not just revenue, to your ad platforms, so Meta and Google can optimise campaigns towards the orders that actually make you money.

Does Littledata protect against bot traffic?

Yes. Littledata's bot protection filters automated traffic out of your tracking, so your analytics and ad audiences are built on real customers.

Does Littledata support Shopify Markets and headless stores?

Yes. Littledata supports unlimited Shopify Markets for cross-border stores and headless and Hydrogen storefronts.
