Google Ads for eCommerce: Strategies, Tips & Examples

Google Ads puts your store in front of people at the moment they search for what you sell. For most eCommerce businesses that makes it one of the first paid channels to get right: you bid in an auction to show ads in Google Search, in Shopping listings, on YouTube, in Gmail, and on partner websites and apps, and you pay mainly when someone clicks.

If you are a growing eCommerce brand trying to get your products seen, or an established store looking for new acquisition and retention strategies, this guide covers the whole picture: how the auction works, how to set up a campaign, which campaign types sell products, and the strategies worth testing. For inspiration from real advertisers, Google publishes its own Google Ads success stories.

How do Google Ads work?

Google Ads campaigns, previously known as AdWords campaigns, are mostly pay-per-click (PPC) advertising. You choose the keywords, products, or audiences you want to reach, and you compete with other advertisers who want to reach the same people. Ads can be short text ads, product listings, images, or videos.

How you pay: bidding options

You pay according to the bid strategy you choose. The main options for an online store are:

• Cost-per-click (CPC). You pay when a user clicks your ad. With Manual CPC you set the maximum you are willing to pay per click yourself.
• Cost-per-thousand impressions (CPM). You pay for every 1,000 impressions, mostly on Display and Video campaigns aimed at awareness. On Display, Google charges viewable CPM (vCPM), so you pay only for impressions that could actually be seen.
• Cost-per-view (CPV). On YouTube video campaigns, you pay when a viewer watches your video ad or interacts with it.
• Smart Bidding. Google sets the bid for each auction to reach a goal you choose: Maximize conversions (optionally with a target CPA) or Maximize conversion value (optionally with a target ROAS). For stores that track order value, conversion value bidding is usually the better fit.

Whatever strategy you pick, you also set a daily budget, which controls how much you spend over a period. Manual CPC with a modest budget is still a sensible way to test a new campaign and get a clearer picture of how expensive it is to advertise your products before you hand the bids over to automation.

Quality Score and Ad Rank

Your bid is not the only thing that decides where your ad appears. According to Google Ads Help, Ad Rank is based on six factors:

1. your bid
2. the quality of your ads and landing page
3. Ad Rank thresholds, the minimum quality an ad needs to show
4. the competitiveness of the auction
5. the context of the search, such as location, device, and time
6. the expected impact of your ad assets and formats

To help you judge quality, Google gives each keyword a Quality Score from 1 to 10, where 10 is the highest. It summarizes three components: expected click-through rate, ad relevance, and landing page experience. Treat it as a diagnostic tool. A low score tells you which of the three to fix.

Why are Google Ads so important for your eCommerce?

Google is the world's leading search engine, and a large share of shopping journeys start with a search. That means your target audience is there, and your competition is definitely there too. Ignoring Google PPC ads is like closing the door on hundreds of people interested in your products, then letting the competition come by and hand out free samples.

The reach goes beyond Search. The Google Display Network alone is a group of more than 2 million websites, videos, and apps where your ads can appear, according to Google Ads Help. YouTube adds video reach on top of that.

Academic research points the same way. In An Analysis on the Use of Google AdWords to Increase E-Commerce Sales (Tricahyadinata and Za, 2017), the authors reviewed eCommerce companies that used Google's ad platform and concluded that it helped them grow website visits, new customers, and sales. The study is several years old and predates today's campaign types, but its main finding still holds.

How to set up a Google Ads campaign

If you have never run Google Ads for eCommerce, the process can look cumbersome at first. It is more intuitive than it seems, and every step is documented in the Google Ads Help Center, so you can always go back and double-check. Google moves menu items around from time to time, so follow the structure below rather than exact button positions.

1. Prepare tracking and your product feed

   Set up Google Ads conversion tracking for purchases, with order value, and consider enhanced conversions for more accurate measurement. Link Google Analytics 4. If you sell products, create a Google Merchant Center account, upload your product feed, and link it to Google Ads.
2. Sign in to your Google Ads account

   If this is your first campaign, sign up for an account first.
3. Create a new campaign

   Use the Create button (the + icon) and select Campaign.
4. Choose your campaign objective

   Google optimizes your ads for the objective you choose, so pick the one most aligned with the result you want to see. For example, choose Awareness and consideration if you are just starting and want more people to know your brand. Be realistic about the results: you will see more awareness, not necessarily more sales from that campaign. Choose Sales when purchases are the goal. You can change your conversion goals later.
5. Choose your campaign type

   Pick the campaign type that fits the objective. For an online store, Performance Max and Shopping both use your Merchant Center feed. Each type is described in the next section.
6. Set bidding and budget

   Choose your bid strategy and daily budget. With purchase values tracked, Maximize conversion value, with or without a target ROAS, lets Google bid more for bigger orders.
7. Set locations and audiences

   Select the geographic areas where your ads can appear. This matters if you run an offline or hybrid store, but even a pure online store can narrow locations to the places where it ships or finds its best customers. Add audience segments or, for Performance Max, audience signals.
8. Create your ads and publish

   Add your headlines, descriptions, images, videos, and final URLs, check the landing pages, and publish the campaign.

Types of Google Ads campaigns

Search campaigns show your business in Google's search results to people searching for terms related to your products. Since June 2022 you build them with responsive search ads: you give Google several headlines and descriptions, and it tests combinations.

Performance Max campaigns are goal-based. They let you show ads on all Google Ads inventory from a single campaign. You provide conversion goals, a product feed, creative assets, and optional audience signals, and Google's automation decides where to serve the ads. Performance Max absorbed the old Smart Shopping and Local campaigns.

Shopping campaigns give users detailed information about your products, such as an image, price, and store name, before they even click an ad.

Demand Gen campaigns replaced Discovery campaigns. They let you tell your brand's story in visual feeds such as YouTube, Discover, and Gmail, to people who are not searching yet.

Video campaigns let you reach and engage your audience on YouTube, one of the most visited websites in the world. Display campaigns show image ads to visitors of websites and apps in the Display Network. App campaigns promote your store's mobile app. Smart campaigns are simple to set up and run mostly on automation.

What are the best types of Google Ads for eCommerce?

1. Shopping campaigns

Shopping ads come first for a reason. If a user searches for a product, they already have a buying intent. With a Shopping ad you advertise to people who are already interested in purchasing products like yours, and they see the image and price before they click, so the clicks you pay for are better qualified. Converting them should not take as much.

Your product feed is the ad. Clear titles that use the words shoppers search for, good images, accurate prices, and up-to-date availability do more for Shopping performance than any bid adjustment.

2. Remarketing campaigns

If Shopping ads let you reach users with high purchase intent, remarketing lets you reach people who have already visited your website or bought from you. Google now calls these lists your data segments. Remarketing does an excellent job in both the acquisition and the retention stages.

Say you sell home decor and want to advertise your kitchen chairs collection. You can create a segment of people who visited your chair pages and show them ads for those chairs. These users are already interested in buying chairs to spruce up their kitchens, so you can draw them back to your store. An extra perk, such as a discount or free returns, can trigger the buying decision.

Remarketing also works for retention and for getting more value from existing customers. If you track the average days between transactions (ADBT), you know when your customers need to restock your products, and you can show them perfectly timed ads. And if your marketing strategy includes cross-selling or upselling, remarketing ads can push complementary products to your existing customers.

3. Performance Max campaigns

Performance Max is where Smart Shopping went. It combines product listings with ads across Search, YouTube, Display, Discover, Gmail, and Maps, and relies heavily on machine learning to choose the best combination of your text, images, and videos for each placement and deliver better results.

If you are unsure of your Google Ads skills, that automation can give you a sense of ease. The trade-off is less control and less visibility into where your budget goes. Performance Max works best with accurate conversion values, a clean feed, and good audience signals, including your own customer lists. Many stores run it alongside Standard Shopping or Search to compare results.

4. Video campaigns

YouTube is one of the largest platforms on the internet, which makes Video ads hard to ignore if you want to engage new shoppers. Video lets your creative team show your brand and your products in action in a way plain text ads cannot. It is easier to digest than text, so you can use it for both prospecting and remarketing.

Google Ads supports several video formats across YouTube and partner sites, including skippable and non-skippable in-stream ads, in-feed video ads, and Shorts ads.

5. Display campaigns

Display ads appear on websites and apps that partner with Google, and the network is large: more than 2 million sites, videos, and apps. However, these ads require more work from your creative team, because you show them to people who are not necessarily looking for your products, unlike Shopping and Search ads.

To be effective, rely on bold, disruptive visuals and persuasive copy that clearly shows the benefits of your product.

Google Ads strategies for eCommerce

It would not be a Google Ads guide without a series of strategies you can try, would it?

1. Use context to create memorable ads

Contextual ads relate to the content around them, or to current trends and events, and they are good at driving awareness of your products. You can use Google Trends to find heavily searched topics and build campaigns around them. On the Display Network, content targeting lets you show ads on pages that match your keywords, topics, or chosen placements, so a running brand can appear next to articles about marathon training.

Because we spend so much of our time online reading and watching content, contextual ads can feel less intrusive than other ads. But do not rely only on contextual advertising, especially if your Customer Lifetime Value is low. These ads bring awareness and put your products in front of new customers, but if your retention game is weak, acquisition soon starts to feel forced. Still, contextual campaigns are fun to try, and they get your products in front of shoppers reading about topics close to your business.

2. Target users with topic and interest ads

If your products fit a specific interest category, or your target audience shares certain hobbies, you can reach that segment with Google's audience segments:

• Affinity segments reach people based on long-term interests and habits, such as outdoor enthusiasts or home cooks.
• In-market segments reach people Google sees actively researching a purchase category.
• Custom segments let you describe your ideal customer yourself with keywords, URLs, and apps. They replaced the separate custom intent and custom affinity audiences.

Interest targeting can range from health and fitness to home decor, travel, and beauty, giving you plenty of segments to try and test. For how to build custom segments and what they can and cannot do, read our custom segments guide.

3. Target your competition

If you want to reach new shoppers who do not know you yet but know your competitors, you can bid on your competitors' branded keywords. In most markets Google allows trademarked terms as keywords, but it can restrict their use in your ad text. Your ad must still be honest about who you are.

Be careful here and do not go after the big players: their budgets are larger, and they can outbid you. A competitive analysis helps you pick competitors you can realistically take on. If your CLV is strong and you know how to play the retention game, it is worth trying to capture some of your competitors' traffic.

How to use your customer data in Google Ads

Since similar audiences were removed, first-party data does more of the work. Customer Match lets you upload lists of your customers so you can show them ads, exclude them from prospecting, or use them as signals for Performance Max. Google requires a Customer Match list to hold at least 100 members added or updated within the last 540 days to stay eligible, so lists need regular refreshes.

Performance Max also supports a new customer acquisition goal, which lets you bid higher for new customers or bid only for new customers. Your Customer Match lists help Google tell new customers from existing ones.

The question is which customers to upload. Not all of them. RFM segmentation scores customers on Recency, Frequency, and Monetary value, and each segment has a different job in Google Ads:

Customer Intelligence in Nexus by Omniconvert builds those segments from your order data and pushes them directly to Google Ads, Meta Ads, and Klaviyo, so your lists stay fresh without manual exports. Nexus is built on 13 years of data across 7,000+ websites and 15+ industries. To see which audiences to build across platforms, read our guide to custom audiences for eCommerce, and for the Meta side of your paid mix, see Facebook ads for eCommerce.

Retention campaigns pay off because it is cheaper and easier to convince customers to repeat their purchases than to win a stranger's trust.
