Google Shopping Ads

Part of our complete guide to ecommerce marketing – this post goes deep on the Google Shopping side specifically.

Key takeaways

• Google Shopping ads are driven by your product data, not keywords – so your product feed is the biggest lever you control.
• You set up products in Google Merchant Centre, then run them through Google Ads as either a Standard Shopping campaign or a Performance Max campaign.
• There’s no minimum spend – you set your own daily budget and pay only when someone clicks.
• Start with Standard Shopping for control and visibility, then graduate to Performance Max once your tracking and feed are solid.

What are Google Shopping ads?

Google Shopping ads are product adverts that show a photo, title, price and store name directly in Google’s results, pulled from the product data you give Google rather than from keywords you bid on. They’re the image-and-price listings you see at the top of a search for something like “cordless drill” or across the Shopping tab.

They were originally called Product Listing Ads (PLAs), and you’ll still occasionally see that term – it’s the same thing. Unlike a text ad, a Shopping ad lets a shopper see the product and the price before they click, which means the clicks you pay for come from people who already like the look of what they’re buying. That’s a big part of why the format works so well for ecommerce, a point we cover in our guide to PPC for niche and B2B ecommerce.

How do Google Shopping ads actually work?

They work by matching your product data to relevant searches, rather than matching keywords you’ve chosen. To advertise on Google Shopping, you don’t pick keywords at all – you give Google a product feed and it works out which searches your products deserve. This is the most important thing to understand about the channel, and it catches a lot of people out.

The chain runs like this: you upload your product information (titles, images, prices, availability and more) to Google Merchant Centre; you link that to a Google Ads account; and Google then decides which of your products to show for which searches, based on the data in your feed. As Google puts it, Shopping ads use your Merchant Center product data, not keywords, to decide how and where to show your ads.

Once running, your products can appear across Google Search, the Shopping tab, Google Images, and – through Performance Max – YouTube, Gmail, Discover and Maps too. You don’t pick keywords. Instead, the quality and structure of your product feed does the targeting for you, which is exactly why the feed matters so much.

Google Shopping vs standard search ads: what’s the difference?

The core difference is simple: search ads are driven by keywords and bids you choose, while Shopping ads are driven by the product data in your feed. With a search ad, you decide the keywords, write the copy and bid on the terms you want. With a Shopping ad, Google reads your product feed and works out which searches your products deserve to appear for.

That changes how you steer the campaign. Because you’re not bidding on keywords, your main control lever is negative keywords – terms you tell Google to keep your products away from. It’s a different way of working, and store owners moving over from search ads sometimes find the loss of direct keyword control unsettling at first. The trade-off is worth it: for a product-based business, letting Google match on rich product data usually beats trying to second-guess every keyword a shopper might type.

Setting up Google Merchant Centre

To run Google Shopping ads you first need a Google Merchant Centre account (Google spells it “Merchant Center”), which is the free platform where your product data lives before it feeds into your ads. If you looked into this a while ago and found something called “Merchant Center Next”, don’t worry – that was the rebuilt version Google rolled out to all retailers through 2024, and in mid-2026 Google dropped the “Next” label entirely. It’s now simply Google Merchant Centre, and there’s nothing extra you need to do about the name.

Setting it up comes down to a few essentials:

• Claim and verify your website, so Google knows the store is yours.
• Add your business information – name, contact details, delivery and returns.
• Add your product data, either manually, via a feed file, or through a direct connection from your ecommerce platform.
• Link your Google Ads account, which is what turns your product data into running ads.

One practical note worth knowing: any campaign you create inside Merchant Centre itself will be a Performance Max campaign. If you want a Standard Shopping campaign (more on that choice below), you build it in Google Ads directly.

It’s also worth switching on free listings while you’re there. Since 2020, Google has shown free product listings on the Shopping tab alongside paid ads, so a well-built feed earns you some visibility even before you spend a penny.

The product feed: where Google Shopping campaigns are won or lost

Your product feed is the single biggest factor in whether Google Shopping works for you, and it’s the part store owners most often neglect. This is the genuine difference between campaigns that quietly waste money and campaigns that transform a business. We’ve seen a retailer’s ecommerce revenue grow many times over across two years primarily by cleaning up product data and running it properly through Google Shopping, reaching a return on ad spend around ten to one – and the lever that did it was the feed, not a bigger budget.

A Google Shopping feed is the file of product data Google reads to decide what to show and when. Google’s own product data specification sets out what’s required. The core attributes every product needs are:

• id – a unique identifier for each product
• title – Google displays up to about 70 characters, so lead with the words that matter (brand, product type, key attributes)
• description – accurate and detailed, with the important information first
• link – the product’s landing page
• image_link – a clean, high-quality image
• price and availability – which must match your website exactly
• brand and GTIN (the barcode number) – Google requires a GTIN for any product that has one, and a wrong or missing GTIN will get the product disapproved

That last point about matching is where a lot of stores come unstuck. If the price or availability in your feed doesn’t match your landing page, or a GTIN is missing or wrong, Google will disapprove the product and it simply stops showing. Disapprovals are the silent killer of Shopping performance – products vanish and the store owner doesn’t notice for weeks.

So the practical work that actually moves the needle is unglamorous: write clear, keyword-rich product titles, use good images, keep prices and stock accurate, fill in GTINs, and keep on top of disapprovals. It’s precisely because this is fiddly and easy to ignore that getting it right is such an advantage. We go deeper on feeds, bidding and realistic returns in our guide to PPC for niche and B2B ecommerce.

Standard Shopping vs Performance Max: which should you use?

There are two ways to run a Google Shopping campaign, and choosing between them is the main strategic decision you’ll make. Standard Shopping gives you control and visibility; Performance Max gives you reach and automation. Here’s how they compare:

Performance Max is Google’s fully automated, goal-based campaign type that spreads your products across every Google channel from a single campaign. It absorbed the older “Smart Shopping” campaigns back in 2022, so if you remember Smart Shopping, Performance Max is where it went.

For a while, the honest criticism of Performance Max was that it was a black box – you handed Google your budget and got very little visibility into where it went. That’s changed. Through 2025 Google added channel-level performance reporting, brought search-terms reporting into Performance Max, and raised the negative-keyword limit from 100 to 10,000 per campaign – all of which make it far easier to keep automation honest. Google also reports its own quality improvements have lifted conversions for advertisers, though that’s Google’s figure rather than an independent one, so treat it as the vendor’s claim.

Our genuine view, from running both: start with a Standard Shopping campaign. The control and the search-term visibility teach you what’s actually converting, and they stop you handing your budget to an automated system before you understand your own numbers. Once your conversion tracking is solid and your feed is clean, Performance Max is the natural way to scale reach – with brand exclusions and a healthy list of negative keywords so it doesn’t quietly turn into an expensive branded-search campaign.

How much do Google Shopping ads cost in the UK?

There’s no minimum spend for Google Shopping ads – you set your own daily budget and pay only when someone clicks. Google works on an average daily budget you choose, and won’t charge you more than roughly 30.4 times that budget across a month, so your spend stays within your control from day one. That makes Shopping genuinely accessible for smaller stores: you can start modestly, learn what works, and scale.

On cost per click, be wary of any “average UK Google Shopping CPC” figure you see quoted online – a lot of them are recycled US data from years ago. There’s no reliable, UK-only public benchmark we’d stand behind. The most current, properly measured figure we’ve seen puts the median ecommerce Shopping CPC at around €0.36 across Europe, but that’s a European median, not a UK-specific number, and your own costs will depend entirely on your products and competition. The only figure that really matters is your own: judge Google Shopping UK performance against your margins and your return on ad spend, not against someone else’s benchmark.

Are Google Shopping ads worth it for small UK businesses?

For most UK stores selling products people actively search for, yes – and the reasons are structural. With 91% of UK searches on Google and more than a quarter of retail spending now online, your customers are already searching Google for what you sell, at the exact moment they’re ready to buy. Shopping puts your product, price and image in front of them there. The entry cost is controllable, and the main success lever – your feed – is entirely within your own hands.

That said, it isn’t automatically right for everyone, and it’s worth being honest about when it struggles. If you’re selling a genuinely new product nobody is searching for yet, Shopping can’t capture demand that doesn’t exist – that’s a job for social-led marketing first. And if your margins are thin and your feed is a mess, Shopping will expose that fast. It rewards stores that have done the unglamorous groundwork.

On the question of doing it yourself versus bringing in help: the mechanics are learnable, and plenty of small stores run their own campaigns perfectly well. Where Google Shopping ads management earns its keep is in the ongoing feed hygiene, disapproval-fixing and bid strategy that quietly compound over time – the work that’s easy to start and hard to sustain alongside actually running a business.

Getting started: a practical checklist

If you’re setting up Google Shopping from scratch, this is the order we’d suggest:

1. Build the foundation. Create your Google Merchant Centre account, verify your site, and build a clean product feed – accurate titles, good images, correct prices and stock, valid GTINs. Switch on free listings.
2. Fix every disapproval before you spend anything. Aim for a feed with no outstanding issues in Merchant Centre.
3. Start with Standard Shopping. Launch with a modest daily budget, watch the search-terms report, and add negative keywords to cut wasted spend.
4. Give it real data. Let it run a few weeks before judging it, and measure against your margins.
5. Scale with Performance Max once your tracking and feed are solid – with brand exclusions and negative keywords in place to keep the automation honest.
