A practical guide to Google shopping feed optimization, with clear steps, common mistakes, and answers to the questions teams ask before they act.
•GOOGLE SHOPPING
Google Shopping Agency
Get every profitable product into the auction, and keep the loss-makers out of it.
We start inside Merchant Center, fix product data at the source, and connect campaign targets to margin and stock. Your Google Shopping agency should get profitable products eligible first, then scale the auctions they can actually win.

•How we help
What Our Google Shopping Services Include
We work through Merchant Center, feed quality, query matching and campaign structure so profitable products can enter the right auctions.
(04)
•The product data Google reads
Titles rebuilt from the queries your products actually receive, and missing attributes completed through a supplemental feed. Every rule is documented, so the next catalog update cannot quietly undo the work.
•Where a disapproval actually comes from
Every disapproval is traced back to the field in your commerce platform that produced it. You get the fault, the field name and the correction to make, so the change happens in the system that actually owns the data.
•Margin written where the bidding can see it
Margin tier, sell-through rate and seasonality written into custom labels, so the bid strategy can tell a profitable item from a merely popular one before it decides what to spend.
•Your price watched against the benchmark
Your prices tracked against the auction benchmark, so a competitor discount arrives as a bid input rather than as a surprise in next month's report.
•Where it breaks
Why Shopping campaigns stop making money
In a Shopping account the money usually leaks in the product data rather than in the bidding. Here is where.
Diagnose my site •01
Products that disappear without explanation
Items drop off the Shopping surface and nothing in the campaign view explains it. The cause sits in Merchant Center rather than in the ad account, which is why no amount of looking at Google Ads will tell you what happened. Left alone the disapprovals spread, because one bad attribute pattern usually repeats across an entire category in your source data.
02
Titles written for your warehouse, not your buyers
Your best products never appear for the searches that describe them, because the titles carry internal naming and the attributes that decide eligibility sit blank. Every week that persists, competitors with complete data absorb the impressions and the auction learns that your listings are the less relevant ones.
03
Your bestsellers are the products losing you money
Bidding is set at campaign level, so a low-margin volume seller and a high-margin niche item chase the same target on the same budget. The volume seller wins every time. Over a quarter the account looks like it is scaling while contribution quietly goes backwards.
04
A cheaper competitor pulls clicks away
Impressions and clicks fall with no change to your bids or your feed. On Shopping the price sits inside the ad, so a competitor discount costs you the click before it costs you the ranking. Ignored, that weaker engagement feeds back into the auction and costs you position as well. The gaps are rarely small: 40.5% of products sold by two or more sellers on Google Shopping cost at least 25% more from the priciest seller than from the cheapest (Google Shopping Price Gaps study).
Our Google Shopping Process
(04)
Phase 01
Week 1
We read the feed and the diagnostics together
Every disapproval, warning and blank attribute gets mapped back to the field in your source system that caused it. You get a fault list grouped by category rather than by item, because the faults almost always repeat across a whole category at once.
Phase 02
Weeks 1-3
We rebuild the titles and fill the attribute gaps
Titles rebuilt against the queries your products receive, missing attributes filled through a supplemental feed, and nothing waiting on an engineering release. Each rule is documented, which is what stops the next catalog import reversing the work. The supplemental feed is yours to keep.
Phase 03
Weeks 4-6
We roll out margin-tier targets one tier at a time
Return targets get set per margin tier rather than per campaign, and we roll them out one tier at a time so any change can be traced to its cause. The tier carrying the most contribution moves last, because it has the most to lose from a learning reset.
Phase 04
Monthly
We review every product on what it contributed
Products get judged on contribution after cost of goods and returns, not on revenue and not on return on ad spend. Earners get more budget. The rest get demoted or switched off, with the reasoning written down. This is the meeting where a bestseller occasionally gets turned off.
•The demand you capture
Shopping buyers compare before they ever click.
A Shopping impression carries your image and your price before anybody clicks, so the qualifying happens inside the auction rather than on your landing page. That makes it the least forgiving surface Google sells. If an attribute is missing, a price is stale or a title does not match the search, you are not in the comparison at all. Delivery data is a common gap: 36.5% of Google Shopping listings show no delivery information at all (Google Shopping study). The work is in the data, not the bid.

•What it costs
Google media spend and agency management fees are scoped as two separate numbers
Paid Shopping placements run through Google Ads, and Google charges you when a shopper clicks, so that budget is set by how much demand you decide to buy. Our management fee is a separate number, driven by catalog size, how many storefronts and countries are in scope, how much of the feed has to be rebuilt, and whether Performance Max sits alongside standard Shopping. We scope all of that first, and the fee for our Google Shopping ads services is fixed in writing before any work starts.
•What stays yours
The Merchant Center account and the feed rules belong to you
We build inside your Merchant Center and your Google Ads account. Supplemental feeds, feed rules, custom-label logic, the fault list and the product-level contribution reporting stay with your team if management changes, and none of it sits behind software you would lose access to.
Google Shopping Deliverables
Google Shopping management should leave you holding assets rather than a login. These are the ones we build and hand over.
Month One
The feed and the campaigns
✓The fault list, grouped by category — Every disapproval, warning and blank attribute mapped back to the source field, grouped by category because that is how the faults actually repeat.
✓Which campaign may bid on which products — The product coverage of every campaign across Standard Shopping and Performance Max, with the inventory filters that keep them out of each other's auctions.
✓Supplemental feeds you keep — Custom labels, promotion data and local inventory built as supplemental feeds and documented, so nothing depends on a release from your engineering team.
✓Weekly product-level optimization — Item-level review with the bid and budget changes made against it, and the reason recorded next to each change.
Months 2-3
Shopping Ads reporting
✓What each product contributed — Revenue, return and margin contribution per item and per category, counted after cost of goods and returns rather than before them.
✓The monthly feed and auction read — Where feed health moved, what the price benchmark did around you, and the two or three things we are changing next.
✓Where Performance Max actually spent — How each asset group performed, which audience signals earned their place, and where the placements landed.

•Frequently asked questions
Common Questions
You need a Merchant Center account, a verified and claimed website, and a product feed that meets Google's data requirements. Once products are submitted and approved they can show as free listings, and paid Shopping placements need a linked Google Ads account and a bid. Most of the effort sits in the feed rather than the sign-up, which is why a Google Shopping agency earns its keep inside Merchant Center.
