Google Ads ROAS dropped: a seven-point diagnosis
Check seven things in order: what Google counts, which campaigns serve, how much is modelled, the calendar, auction prices, the feed and the tag. Compare each one with Shopify orders before you change a bid.
Pinterest Ads underperforming? Check the window first
Pinterest counts conversions inside a click window and a view window and reports them against the day of the ad, so recent days look thin and late sales land in other GA4 channels. Check the window, then hold out a region before you cut.
Why retargeting ROAS looks better than it is
Retargeting shows ads to people who already visited your store, so the platform can credit the ads with purchases that would have happened anyway. A regional holdout on your own audience measures how many.
Snapchat Ads ROAS looks low: what the dashboard misses
Snapchat's dashboard credits only the purchases it can link to an ad, and on iPhones some links break. Reconcile its count with GA4 and Shopify for one week, then hold out a region to see what the ads caused.
Meta Ads ROAS dropped: what changed and what to check
Check how Meta counts, whether the ad is tiring, whether prices rose, and whether the calendar or tracking moved. Meta's own results say its average price per ad rose year over year in the second quarter.
Meta Ads vs Shopify revenue: why the totals differ
Meta counts purchases it links to an ad inside a window that includes views, reports them on its own date basis and can count a duplicated event twice, while Shopify counts each order once. Aligning window, date and currency for one closed week shows what is left.
TikTok Ads not converting? Read this before you cut
Don't cut on TikTok's in-platform count alone: it credits clicks and views inside a window, and some of the conversions it credits show up as Direct in GA4. Split the count by click and view, then test a cut in one region.
Why ROAS falls when you scale spend (and what to watch)
Extra spend has to buy conversions that cost more than the first ones, so the average falls while the marginal return falls faster. A step-up test in one region reads the marginal return directly.
Google Ads vs Shopify revenue: why the numbers differ
Google Ads dates a conversion by the ad interaction and credits it under its own model, while Shopify dates the order and nets returns when they happen. A closed-week reconciliation separates the explainable gap from a counting fault.
The 3-Tier Framework to Pay Off Your Attribution Debt
Twelve plays across three tiers, run in order. Tiers 1 and 2 are free DIY. Tier 3 is causal measurement. The plan to pay off attribution debt, and where to start.
Marketing Attribution for Multi-Platform Brands
Why a brand that sells through several stores, such as Shopify, WooCommerce and Magento, gets different numbers from each one, and why GA4 is the one source those stores can share.
Marketing Attribution for Multi-Channel Brands
Causality Engine provides multi-channel attribution specifically for DTC ecommerce brands: from your GA4 export, it shows what each channel caused, next to what last-click gave it.
Marketing Attribution for Influencer-Driven Brands
Marketing Attribution for Google Ads-Heavy Brands
Google Ads grades its own homework: a buyer who saw a YouTube ad and clicked a Shopping ad counts for Google, even if email or organic search mattered more. Test whether each campaign type creates demand or catches sales you'd get anyway.
Marketing Attribution for Meta Ads-Heavy Brands
Causality Engine brings causal marketing attribution to DTC ecommerce brands that rely on Meta Ads: it reads a GA4 export, not Meta's pixel, and shows what each channel caused next to what last-click gave it.
Marketing Attribution for Custom eCommerce Platforms
Causality Engine brings causal marketing attribution to custom ecommerce platforms without an integration project: it reads a GA4 export and shows what each channel caused next to what last-click gave it.
Marketing Attribution for Magento Stores
Set up marketing attribution on a Magento store with GA4 purchase events that match your orders, one UTM scheme across stores, and a monthly check of what each ad platform claims against your orders.
Marketing Attribution for DACH Region Brands
Selling across Germany, Austria and Switzerland means consent requirements for German consumers, several languages and sometimes separate regional marketing. Why that makes attribution hard for DACH brands.
Marketing Attribution for EU/GDPR-Compliant Brands
Attribution that holds up under GDPR works from totals, not individual journeys: compare platform claims with your orders, test one channel in one country, and track total revenue against total ad spend.
Marketing Attribution for Shopify Stores
Causality Engine brings causal marketing attribution to Shopify stores, moving beyond unreliable last-click data to show what each channel caused, from a GA4 export.
Marketing Attribution for WooCommerce Stores
WooCommerce stores often run many plugins that create data silos, and Meta, Google Analytics and the CRM report conflicting numbers. Why that makes attribution hard for WooCommerce stores.
Marketing Attribution for Bootstrapped Brands
Bootstrapped brands have no outside funding, so every marketing euro has to pay back. Why that makes attribution hard for lean teams that often run marketing in house with limited tools.
Marketing Attribution for UK eCommerce Brands
Attribution works the same for a UK store as for any other: last click hands each sale to the final touch, so check it against what each channel caused. The UK part is compliance: UK GDPR applies, alongside EU GDPR if you sell into both.
Marketing Attribution for Startups
Startups with limited budgets and no existing attribution infrastructure need a fast, affordable, and accurate way to understand which marketing channels drive actual revenue.
Marketing Attribution for Sports & Outdoor Brands
Judge campaigns against the season, not the last click: a peak-season ski ad can look great on sales that were coming anyway, so compare year on year. Last click also hands athlete, influencer and club sales to Direct or brand search.
Marketing Attribution for Food & Beverage Brands
For food and beverage brands a single purchase is rarely the goal: repeat buyers and subscribers are. Why attribution that credits only the first purchase leaves out the path to the later ones.
Marketing Attribution for Home & Living Brands
Shoppers research, compare and deliberate before an infrequent, high-value purchase like furniture or decor. Why crediting only the last touch gives an incomplete picture for Home & Living brands.
Marketing Attribution for Health & Wellness Brands
Health and wellness brands deal with strict ad rules that limit targeting, long education journeys and top-of-funnel content that is hard to tie to later purchases. Why those limits make attribution harder.
Marketing Attribution for Beauty & Cosmetics Brands
Causality Engine brings causal marketing attribution to beauty and cosmetics brands, showing what each channel caused, next to last-click, from a GA4 export.

Audience Overlap Attribution Issue: Stop Paying Twice for the Same Customer
Audience overlap causes multiple channels to claim credit for the same conversion. Learn how to detect and resolve overlap with causal inference.
Google Analytics 4 Attribution Limitations You Need to Know
GA4's three attribution models share out credit among the clicks it recorded, and none tests what a channel caused. Where that misleads Shopify brands, and three checks to run on your own data.
Facebook Pixel Inaccuracy: Why Your Conversion Data Is Wrong
Browser tracking prevention, attribution window bias, cross-device gaps and event deduplication errors can make Facebook Pixel data inaccurate. That leads to misestimated ROAS and inefficient budget allocation.
TikTok Pixel Attribution Issues: What the Data Really Shows
TikTok Pixel often overattributes conversions due to tracking limitations and attribution windows. Discover how Bayesian causal inference delivers clearer attribution insights.
Diminishing Returns on Ad Spend: When to Stop Scaling
Scaling ad spend blindly leads to diminishing returns. Learn how to identify the inflection point using Bayesian causal inference for Shopify brands.
Offline to Online Attribution: Bridging the Data Gap
Offline spend cannot be clicked, so the tools that measure it (Rockerbox, Measured, Recast, Haus, Fospha) model its influence on online sales rather than track it. Causality Engine reads a GA4 export, which holds no offline data, so it covers online channels only.
Seasonal Sales Attribution: Separating Marketing Impact from Trends
Holidays, events and weather can lift sales whether or not you advertise. This post explains why last-click and rule-based models misread seasonal peaks, and what that does to budget decisions.
Subscription Revenue Attribution: Measuring Long Term Marketing Value
Subscription brands earn revenue over months or years, yet short-term attribution credits only the first purchase. This post explains why lifetime value, renewals and churn belong in the picture.
