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.

Klaviyo Reviews collects text, photo, and video reviews with automated email and SMS requests from prebuilt flows. Verified reviews build trust, and AI helps customers write reviews and drafts your replies in your brand voice. Show ratings, summaries, and reviews in on-brand widgets, sync to Google Shopping, and add custom questions. Because reviews live in your CRM, segment on ratings, personalize across channels, feature reviews in campaigns and flows, and route low ratings to support.
