Google Shopping Ads: How They Work and What to Fix First
By Josh Croom · October 27, 2026 · 11 min read
Google Shopping ads show a product's photo, title, price and store name right in Google's results, and you pay only when someone clicks. They run on your product feed in Google Merchant Center instead of keywords, so the words in that feed decide which searches your items appear for.
The boots that didn't show
11:48 PM. A buyer on her couch types "women's waterproof hiking boots wide size 8" into Google. A row of boots appears, each with a photo, a price and a store name, and she taps the second one.
Your store sells that exact boot, in her size, and it's in stock. It didn't show up, because two weeks ago your site changed the price and the feed kept the old one. Google opened the boot's page, saw that the two prices didn't match and switched the listing off. Nobody on your team saw the notice.

What Google Shopping ads are
A Shopping ad is a product card with a photo, a title, a price and your store's name, and sometimes a rating or a shipping note.
Google's help page says Shopping ads use your Merchant Center product data, not keywords, to decide how and where your ads show. You're charged per click, and only when a shopper clicks through to your page.
Standard Shopping campaigns show your catalog on the Shopping tab, Google Search, Google Images and, if you turn them on, partner sites. Performance Max campaigns can reach those spots plus YouTube, Gmail, Maps and the display network. The same feed also fills unpaid listings in the Shopping tab, which cost nothing when a buyer clicks one.
Every campaign can only show what your feed says about each item.
| Standard Shopping | Performance Max | |
|---|---|---|
| Where it shows | Shopping tab, Search, Images and partner sites | All of those, plus YouTube, Gmail, Maps and the display network |
| What it runs on | Your product feed | Your product feed, plus the images, videos and text you add |
| How you steer it | Product groups, bids and negative keywords | Asset groups, the products in each one and your sales goals |
How your feed becomes an ad
Every Shopping ad starts as one row in your feed, and that row goes through five steps before a buyer sees it.
Step 1
Your store sends the feed
Each product goes to Merchant Center with its title, price, stock, photos, link and details like size or color. Most stores send it through a plugin or an app, so the feed updates when the store changes.
Step 2
Google reviews every item
Google checks each item, its page and its photos against its policies. It also opens the page and compares the price and stock with the feed, and when they don't match, it may correct the number itself or switch the item off.
Step 3
Google matches searches to your data
It reads your title, description, product type and brand to decide which searches fit. A title that opens with what the item is, then the model or size, matches more of the right searches.
Step 4
Bidding learns from your sales
Your purchase tracking reports each sale and what it was worth. Over time, the bidding learns which items, searches and shoppers lead to orders, and it bids more where they do.
Step 5
Offers show on the ad
A sale price in your store's sale price field, with start and end dates, can show on the ad as a marked-down price. A code or a shipping deal at checkout can become a promotion under your listings once Google approves it.
What we found in five store feeds
In October we read five store feeds in Merchant Center to see how much of each catalog could show. Google had cleared most items, and it had switched off the rest, left them waiting on review or kept them out of ads.
- 90%of products cleared for U.S. Shopping adsfive store feeds, October 13, 2026
- 10%had a price or stock status that didn't match the product pageGoogle found it when it opened the page
- 1.4%had a product link Google couldn't openin the same five feeds
An item that's switched off can't sell at any bid, which is why links, prices and stock come first and titles come after.
Fix the blockers first
Open Merchant Center and find every item Google switched off or flagged, since each one comes with a written reason.
Fix the cause in your store, and the next sync carries the correction to Merchant Center. Google's rules ask you to match the feed price with your page, its structured data and your checkout, so when a price changes on your site, the feed has to change the same day.
Make every change in your store, not in Merchant Center. Your store sends the feed again on its own schedule, and it writes over any edit you typed in by hand. And never set a sold-out item's price to zero; mark it out of stock instead.
For a sale, put the sale price in the sale price field with start and end dates, and keep sending the regular price beside it. Editing the regular price down for a weekend sale makes the feed and the page disagree as soon as the sale ends.
Write titles the way people search
Your title does the job a keyword does in a search ad, so open with what the item is.
Buyers search for exact things. On three of our store accounts, 19% of search ad clicks came from searches with a number in them, like a model or a size. A title with the model and size in it can match those searches. A title like "Trail Boot" can't.
Google allows up to 150 characters in a title, but it says shoppers usually notice only the first 70 or fewer on their screen. So put what the item is first, and follow it with the model it fits, its size, color and material.
Merchant Center's rules bar prices, sale words, shipping offers, dates and your store's name from titles, along with capital letters used for emphasis. Rewrite your best sellers first and then work down the list a few each week. When you add something new, check its title, photo, price and stock during its first week.
A title that hides
- Trail Boot by Our Store
- BEST HIKING BOOT, SALE ENDS SUNDAY
- Hiker 2 (brown)
A title that gets found
- Women's Waterproof Hiking Boot, Wide Fit, Size 8, Brown Leather
- Men's Insulated Work Boot, Steel Toe, Size 11, Black
- Men's Leather Belt, 1.5 Inch Wide, Size 36, Brown
Ten feed fixes to tick off
Work through these on your best sellers first, then the rest of the catalog. Your ticks stay on this device.

Use your support tickets to fix product pages
People search the way they talk to your support team, so the questions in your inbox often hold the exact words your pages are missing.
Give every ticket one of the five tags in the table, so you can count them each month. Copy the buyer's exact words, because "Will this fit a 2019 model?" is what the next buyer types into Google, and "fit question" isn't. When you can, ask the buyer what they searched to find you, and write the answer down word for word.
Once a month, take your top tag and fix the page behind it on your best seller, in the buyer's words. A fit list, a size chart or a short how-to answers the next buyer before they write in, and it gives Google those same words to match. If a buyer saw one price on Google and another on your site, fix that the same day in your store.
| Tag | Capture this | Fix it here |
|---|---|---|
| Fit or size | The model or size | A fit list, a size chart and the title |
| Shipping | What they expected | Shipping cost and dates on the page |
| Price | Where they saw each price | The price in your store |
| Return | The reason, in their words | Photos and product details |
| How to use | The question they asked | A short how-to on the page |
How buyers really search
Is your feed ready for Shopping ads?
Answer five quick questions. Your answers stay on your screen.
Does every link in your feed open the right item, in stock, at the feed's price?
Does your feed update the same day a price or stock level changes on your site?
Do your best sellers' titles start with what the item is?
Have you checked Merchant Center for switched-off items in the last week?
Do your sale prices sit in the sale price field, with dates?
Your feed is in good shape. Keep checking each new listing in its first week, so a weak title or a missing photo gets caught early.
You're close. Fix the first question you answered No, starting with links and prices, because a switched-off item can't sell.
Start in Merchant Center today and find the items Google switched off. Read each reason and fix the cause in your store, then come back to the titles.
What Google Shopping ads cost
You pay Google per click, and you set the budget, so the ad cost stays in your hands.
What a click costs depends on what you sell, your prices and who else is bidding, so watch what each sale costs you. Your purchase tracking reports it. To make sure that tracking works, run the conversion checks in our PPC audit checklist.
If you'd like us to run it, Open Spots Store is $997 every 4 weeks, plus a $1,997 build paid once, or $0 on the 13-cycle plan. We set up or fix your product feed in Merchant Center, add tracking that shows which orders came from your ads, and run Shopping and Performance Max with as many campaigns as your store needs. Your own card pays Google, in your own Google Ads and Merchant Center accounts. Every price we charge is on our pricing page.
We’ll have your Shopping or Performance Max campaign live and tracking a test order within 21 days of getting your access and answers, not counting the days Google takes to review your products. If we miss that and the delay is on us, you don’t pay your first 4-week fee.
Where to start this week
Open Merchant Center, fix what's turned off and rewrite the titles on your five best sellers. Standard Shopping also lists the searches behind each click. Our search terms study explains how to read that report and block searches that will never buy.
If you'd like a second set of eyes on your feed, book a call with Miguel. He'll ask how your store sends its feed today and talk through what's worth fixing first.
Questions people ask
How do Google Shopping ads work?
Your store sends a product feed to Google Merchant Center, with a title, price, photo and link for each item. Google checks each one, and your Shopping or Performance Max campaigns turn the approved items into ads. It then matches searches to the words in your feed, and you pay only when someone clicks.
Do Google Shopping ads use keywords?
No. Google reads your product data instead, and it leans on your titles, descriptions, product types and brand. You can still add negative keywords to block searches that don't fit.
Why are my products not showing in Google Shopping?
An item may have broken a policy or sold out, or Google found a page that didn't load or a price that didn't match. Merchant Center lists everything it switched off, along with the reason, so start there and fix the cause in your store.
What's the difference between Shopping ads and Performance Max?
Both run on your product feed. Standard Shopping shows your products on the Shopping tab, Search, Images and partner sites. Performance Max can also put them on YouTube, Gmail, Maps and the display network, and it uses the images, videos and text you add.
How much do Google Shopping ads cost?
You pay Google per click and set your own budget. If we run them, Open Spots Store is $997 every 4 weeks plus a $1,997 build, and your own card pays Google directly.
