Inside Google Ads eCom Lab: Q2 2026 community update

Q2 2026 is the most active quarter the Google Ads eCom Lab has had since it launched.

740+ operators inside. New modules dropping every Monday. Thursday teardowns filling up faster than they used to. Monthly live calls with more accounts submitted for review than any previous quarter.

The community is not a static resource you join and forget. It is a working room. And Q2 gave us a lot to work through - Google's changes to Performance Max search-term visibility, the Demand Gen migration from Discovery, and tracking discrepancies that are showing up across more accounts than expected.

This is the Q2 2026 state-of-the-union for Google Ads eCom Lab. What shipped, what we are seeing in accounts, what to do next.

New modules that shipped in Q2 2026

The classroom is where the structured learning lives. Q2 dropped six new modules based on what the ZenoX team is seeing across 200+ live client accounts.

Demand Gen for ecom operators. Google retired the Discovery campaign type and replaced it with Demand Gen. The two are not the same. Demand Gen has YouTube Shorts placements, native video support, and a different audience targeting model. This module covers how to set up Demand Gen for ecom stores, which placements work for which verticals, and how to use it alongside Performance Max without cannibalising budget.

Server-side tracking validation. The ZenoX Shopify app does the install. This module covers the validation step that most operators skip - confirming that the events Google receives match the events Shopify records. How to read the conversion data in both platforms. What a discrepancy means and how to fix it. Why this step matters more than the install.

Performance Max search-term reporting. Google released an updated search terms insight report for PMax in Q1 2026. This module covers how to read it, what signals to extract, and how to use the data to restructure your listing-group rules. Most operators who saw their PMax insight report for the first time in Q2 discovered their campaigns were bidding on queries they did not expect.

Custom label velocity refresh. Static custom labels set at launch get stale as product velocity changes. A product that was "hot" in Q4 may be "mid" in Q2. This module covers how to build a velocity refresh cadence - updating margin band and velocity labels quarterly based on 90-day sales data. Connects directly to the PMax listing-group rules so the bidding stays aligned with current product performance.

Budget scaling rules for Q2 2026. How to push budget when ROAS holds. When to step from $100/day to $200/day to $500/day. How to handle the post-scale learning period without triggering a ROAS drop. Built from the budget scaling patterns ZenoX ran across client accounts in Q1-Q2 2026.

Merchant Center Q2 compliance update. Google updated policy enforcement in several categories in Q1 2026. This module covers what changed, which niches are more exposed, and how to audit your product feed for the new policy triggers before they cause disapprovals.

What the Q2 teardowns showed

Every month, members submit accounts for live review on screen-share. Q2 had more submissions than any previous quarter. Here is what came up most often.

The single-asset-group PMax problem

The most common structural issue across Q2 teardowns: all products in one PMax campaign, one asset group, no listing-group rules beyond the default "All products."

This structure forces Smart Bidding to bid on a blended margin across the entire catalogue. It cannot distinguish between the 60% margin hero product and the 18% margin clearance line. Budget flows to the highest-volume products, which are often not the highest-margin products.

Every account that had this structure got the same recommendation: split by margin tier using custom labels. Three accounts submitted their results after implementing the split. Average ROAS lift: 22% within two weeks. Zero budget increase.

The tracking discrepancy pattern

Over half of the accounts reviewed in Q2 teardowns had a measurable gap between Shopify-reported conversions and Google Ads-reported conversions. In most cases, the gap was 25-40%.

The cause is always the same: browser-side pixel tracking losing events to ad blockers and iOS privacy updates.

The fix is always the same: server-side tracking. The ZenoX Shopify app for Shopify stores. GTM Server-Side for other platforms. After the install, conversion counts in Google Ads recover to match Shopify. Smart Bidding immediately recalibrates on the correct data.

The pattern is so consistent that it is now the first thing checked in every teardown session. If tracking is broken, everything else is downstream of a bad foundation.

The tROAS starvation pattern

The third common pattern: accounts where tROAS was raised every time ROAS dipped, and now the algorithm is starved.

Smart Bidding tries to hit the tROAS target. When tROAS is set too high, the algorithm stops bidding on anything that might not hit the target. Impression share drops. Clicks drop. Conversions drop. Reported ROAS looks fine (because Smart Bidding is only showing ads it feels confident about) but volume collapses.

The fix is counter-intuitive: drop tROAS to 220% and let the algorithm breathe. Impressions typically double in 5 days. Let it run for 14 days, then nudge tROAS up 5% every two weeks if efficiency holds.

Three accounts implemented this during Q2. All three had impression share recover within a week. Volume followed.

What ZenoX is seeing across 200+ client accounts right now

The eCom Lab curriculum is built from what ZenoX sees in the MCC data across 200+ live client accounts. Q2 has two dominant patterns.

Feed quality is the top lever. Accounts with intent-matched titles, correct margin band custom labels, and clean item group ID structure consistently outperform accounts with default supplier feeds - even when campaign structures are identical. The gap is usually 15-30% ROAS. The structural work that moves accounts most is in the feed, not the campaign settings.

Tracking gaps are still widespread. Despite increasing awareness of the issue, most ecom accounts are still running on broken browser-side tracking. The standard ZenoX onboarding now includes a tracking audit as step one. In Q1-Q2 2026, more than 60% of new client accounts had measurable tracking discrepancies at onboarding.

Both patterns are curriculum priorities in Q3 2026. Two new modules are planned: a feed audit framework operators can run on their own accounts, and a tracking discrepancy diagnostic for stores that are not sure if their data is clean.

What to do if you are not in the community yet

The momentum in Q2 is real. The operators inside are applying the modules, posting teardown submissions, and sharing their results. That active room is what makes the community more valuable than a static course.

Join Google Ads eCom Lab at skool.com/google-ads-ecom. Thirty seconds, no credit card, full access.

When you land inside, go to the classroom first. Start with the tracking validation module - it is the most urgent fix for most accounts. Then check the Q2 module drops. Then post in the feed and introduce your store.

The operators in chat will tell you what to look at for your specific account.
