Google Shopping Ads Reporting for Marketing Agencies

Google Shopping Ads Reporting for Marketing Agencies

Google Shopping ads reporting is the practice of pulling campaign, product, and Merchant Center data into a clear, recurring report that shows a client exactly what their Shopping spend returned. For agencies running e-commerce accounts, it is one of the hardest reports to get right, because the story lives across three places at once: Google Ads (campaign and product performance), Merchant Center (feed health and disapprovals), and GA4 (what happened after the click). Pull them apart and you get three disconnected screenshots. Pull them together and you get a report a client reads to the end.

We built ReportsMate email-first because, after years around agency reporting, the dashboards clients were handed almost never got logged into. The Shopping report that lands in the inbox on a Monday morning is the one the client actually reads. This guide covers what to include, how to structure it, which tools do the job, and how to stop losing hours to it every month.

Key takeaways

• Google Shopping ads reporting spans three data sources: Google Ads (campaigns and products), Merchant Center (feed health), and GA4 (post-click revenue). A complete report ties all three together.
• Report on product-level performance, not just campaign totals. Shopping success or failure is usually driven by a handful of products or a broken feed.
• ROAS, cost, conversion value, impression share, and product feed health are the five metrics that belong in every Shopping report.
• Most Shopping now runs through Performance Max, so blend Shopping-specific views with PMax reporting rather than treating them separately.
• A repeatable shopping campaign report template plus automated delivery turns a multi-hour job into a scheduled email.

Best Google Shopping ads reporting tools for agencies

The best Google Shopping ads reporting tool for an agency is the one that combines Google Ads and Merchant Center data, white-labels the output, and delivers it automatically without anyone logging in. ReportsMate is built around email-first delivery; the tools below all handle Shopping data well but differ in how the client receives it. We build ReportsMate, so treat this as our honest read of the market rather than a neutral referee.

The real split is not the metrics; every tool can show ROAS and cost. It is whether the client ever sees the report. Dashboards depend on the client logging in, and most do not. Email-first flips that: the report arrives, so it gets read. To see how the automated delivery works end to end, our how it works page walks through connecting Google Ads, setting a schedule, and sending.

What to include in a Google Shopping ads report

A strong Google Shopping ads report answers one question per section: is spend efficient, which products drive it, and is the feed healthy. Lead with the headline outcome (revenue and ROAS), then break it down. Clients care about the money first and the mechanics second.

The metrics that belong in every Shopping report:

• Cost and conversion value - total spend against the revenue it generated.
• ROAS (return on ad spend) - the single number most e-commerce clients judge you on.
• Conversions and conversion rate - volume and efficiency of purchases.
• Impression share and lost impression share - how much of the available Shopping auction you are capturing, and whether budget or rank is the limiter.
• Average CPC and click share - competitiveness at the click level.
• Product feed health - active vs disapproved products in Merchant Center.

For definitions of the auction-level numbers, Google Ads Help documents impression share and Search lost IS in detail. If you also want a benchmark for what "good" looks like, our guide to what is a good ROAS for agencies puts client expectations in context before you present the number.

Merchant Center reporting and feed health

Merchant Center reporting tells you whether your products are even eligible to show, which is the part most agency Shopping reports skip. A campaign can look like it is underspending when the real cause is that half the catalogue is disapproved and cannot enter the auction. Feed health is a first-class metric, not a footnote.

In a client report, surface three feed signals: total active products, disapproved products with the top reason (missing GTIN, price mismatch, policy), and any products in a "pending" or "limited" state. Google documents the fixes in Merchant Center Help, and the newer Merchant Center Next reorganises where these diagnostics live. The point for reporting is simple: a client who sees "38 of 210 products disapproved" understands instantly why revenue dipped, and understands that fixing the feed is the lever, not raising the budget. That is the kind of insight that keeps a retainer. Our Google Ads integration pulls this alongside campaign data so the feed story and the spend story sit in one report.

A shopping campaign report template that works

A good shopping campaign report template follows a fixed order so clients learn where to look and you never rebuild it from scratch. Consistency of layout is itself a retention tool: the report becomes a familiar habit rather than a new puzzle each month.

Use this structure:

1. Executive summary - revenue, ROAS, spend, and one plain-English sentence on the month.
2. Performance vs previous period - the same core metrics, month over month.
3. Top and bottom products - your best revenue drivers and your budget-wasters.
4. Feed health - active vs disapproved products from Merchant Center.
5. Impression share - opportunity you are leaving on the table.
6. Next actions - two or three specific recommendations.

That "next actions" block is what separates a report from a data dump. It is where insider work shows: reallocating budget to high-ROAS products, fixing feed disapprovals, or raising bids to capture lost impression share. If you want a ready-made starting point built for online stores, our e-commerce marketing report template for agencies lays out the sections and the metrics to drop into each.

Product feed performance reporting

Product feed performance reporting means measuring results at the individual product level, not just the campaign level, because Shopping outcomes are almost always concentrated. The classic pattern is that 20 percent of products drive 80 percent of the revenue, while a long tail of items quietly burns budget with clicks and no conversions.

Report on product performance with three views: top revenue products, top spenders with low or zero conversions, and products with high impressions but low click-through (usually a title, image, or price problem). This is where full-funnel attribution matters, so pair Google Ads spend data with GA4 e-commerce revenue to see what actually converted after the click. Google's own documentation covers GA4 e-commerce reporting, and our companion guide to GA4 e-commerce reporting for agencies shows how to line the two data sources up without double-counting.

Performance Max and Shopping in one report

Most Google Shopping inventory now serves through Performance Max, so a modern Shopping report has to cover both Standard Shopping and PMax rather than treating Shopping as a standalone channel. PMax blends Shopping, Search, Display, and YouTube inventory, and its reporting is less granular by design, which frustrates agencies used to product-level control.

The practical approach: report PMax at the campaign and asset-group level, layer in the listing-group (product) performance Google does expose, and be honest with clients about what PMax hides. Do not pretend to a product-by-product breakdown that the platform does not surface. For the deeper mechanics of reporting on this campaign type, our Performance Max reporting for agencies guide covers the workarounds, and our Google Ads reporting best practices for agencies sets the wider standard for how these reports should read.

Frequently asked questions

Q: What metrics should a Google Shopping ads report include?

A: Every Google Shopping ads report should include cost, conversion value, ROAS, conversions and conversion rate, impression share, average CPC, and product feed health. ROAS is the headline number most e-commerce clients judge campaigns on, so lead with revenue and return, then break performance down by product. The metric agencies most often forget is feed health from Merchant Center, which explains why products may not be showing at all. For a benchmark on the return side, see our guide to what is a good ROAS for agencies.

Q: How do I report on Merchant Center feed health to clients?

A: Report feed health with three numbers: active products, disapproved products with the top disapproval reason, and products in a limited or pending state. This turns an invisible technical problem into a clear business one - a client who sees "38 of 210 products disapproved" understands why revenue dropped without needing a lecture on the feed spec. Google's Merchant Center Help documents the common disapproval causes and fixes. ReportsMate pulls this alongside campaign data through the Google Ads integration.

Q: What is the best Google Shopping ads reporting tool for agencies?

A: The best tool combines Google Ads and Merchant Center data, white-labels the output, and delivers it automatically. AgencyAnalytics, Whatagraph, Swydo, Supermetrics, and Looker Studio all handle Shopping data, and they mainly differ in delivery. ReportsMate is email-first, so the branded report lands in the client's inbox instead of waiting behind a login most clients never use. See how it works for the connect-and-schedule flow.

Q: How does Performance Max change Shopping reporting?

A: Performance Max now serves most Shopping inventory, and it blends Shopping with Search, Display, and YouTube, so reporting is less granular than Standard Shopping. You can still report at the campaign, asset-group, and listing-group (product) level, but PMax hides some channel and placement detail by design. The honest approach is to report what the platform exposes and be transparent with clients about the rest, rather than inventing a breakdown that does not exist.

Q: How often should agencies send Shopping ads reports?

A: Most agencies send Shopping reports monthly for the full performance picture, with a lighter weekly snapshot for high-spend accounts where a feed disapproval or budget issue needs catching fast. E-commerce moves quickly around promotions and seasonal peaks, so higher-spend clients often warrant weekly delivery. The right cadence is the one that keeps clients informed without overwhelming them, and automated scheduling means a tighter cadence costs you no extra hours.

Q: Can Google Shopping reporting be fully automated?

A: Yes. Connect Google Ads and Merchant Center once, choose a schedule (daily, weekly, or monthly), and the report is generated and delivered automatically. Automation removes the manual export-and-format cycle that eats 15 or more hours a week across a full client roster, and it removes the human error that creeps into copy-pasted spreadsheets. With ReportsMate the report is also white-labelled and sent from your own domain, so it reads as your agency's work.

Getting Shopping reporting off your plate

Google Shopping ads reporting is fiddly because the data is scattered and the client only cares about the outcome. The fix is a fixed template, product-level detail, feed health included, and automated delivery so it happens without you. Get that right and Shopping reporting stops being the report you dread and becomes a quiet monthly proof of the value you deliver.
