The way you structure Google Ads campaigns for an e-commerce brand has a direct effect on performance. A well-structured account gives you control over where the budget goes, clear data on what works, and a base you can scale. A poorly structured account hides problems, spreads data too thin for the bidding system to learn from, and makes optimisation hard. This guide covers the structure that works for most e-commerce accounts.
Start with Campaign Type Logic
E-commerce brands usually need three kinds of campaign running side by side:
- Shopping campaigns (Standard Shopping or Performance Max) to capture demand from people searching for products you sell.
- Search campaigns to capture branded searches and high-intent non-brand queries that Shopping does not cover well.
- Remarketing campaigns (Display, YouTube or Demand Gen) to bring back visitors who did not buy.
Starting with Shopping makes sense for most accounts because it puts the actual product, price and image in front of people searching for it. For many product queries, a Shopping ad is more useful to the shopper than a text ad. Once Shopping runs profitably, add Search for brand terms and high-intent modifiers, then add remarketing to recover lost conversions.
How to Structure Shopping Campaigns
The key structural decision for Shopping is how to segment products. Putting every product in one campaign leaves you no control over budget allocation and makes it impossible to prioritise high-margin items.
A practical way to segment:
- Best sellers and high-margin products. These get the largest share of budget and a target return on ad spend (ROAS) that reflects the real margin on these items.
- Mid-tier products. Items with moderate margin or volume sit in a separate campaign with a smaller budget.
- New arrivals and test products. These can be tested without disturbing proven performers.
If you are deciding between campaign types, read our comparison of Performance Max vs Standard Shopping. Setting the right targets matters just as much, and our guide to what counts as a good ROAS for Google Ads explains how to base targets on margin instead of a round number.
How to Structure Search Campaigns
Keep branded and non-branded keywords in separate campaigns. Branded searches usually convert better and cost less per sale, so when they share a campaign with non-brand terms they make the non-brand results look better than they are. The branded campaign will nearly always look healthy. The non-brand campaign shows how the market really responds to your ads.
Within non-brand Search, segment by product category or intent level. A broad search such as “running shoes” has different economics from a specific one such as “men’s trail running shoes size 10”. Exact and tightly controlled phrase match keywords in dedicated ad groups give you more control than broad match across everything. Our guide to broad, phrase and exact match in 2026 explains when each one fits.
Ad Group and Landing Page Structure
Each ad group should hold keywords with similar intent and send traffic to a relevant landing page. Avoid sending ad groups to your homepage. Send people to the product or category page that matches what they searched for. A homepage makes visitors hunt for the item, and that usually lowers the conversion rate.
Review the search terms report regularly to see what people actually typed, and use it to move good queries into their own ad groups.
Automated Search Campaigns and Negative Keywords
Automated Search options such as Dynamic Search Ads work as a catch-all for queries your regular keywords miss. Keep them in a separate campaign. Without that separation they can pull budget away from priority campaigns and show ads for products you did not intend to promote.
Negative keywords are essential here. Exclude product lines, price points or categories where you do not want ads to appear. Our guide to Google Ads negative keywords explains how to build and maintain that exclusion list.
The Remarketing Layer
Once Shopping and Search are running, add remarketing aimed at people who visited your site but did not buy. Dynamic remarketing shows people the specific products they viewed, which tends to work better for e-commerce than generic banner ads. Segment these audiences by recency, because a visitor from the last three days should see different messaging from a visitor from two to four weeks ago.
Maintaining the Structure Over Time
Campaign structure is not a one-time setup. It needs to change as your catalogue grows and as you learn which segments earn their keep. Review it every quarter. A fast-growing category may deserve its own campaign, and a campaign that chronically underspends may be better merged with a related one. If you are building from scratch, our guide to setting up a Google Ads account the right way covers the foundations to check first.
Frequently Asked Questions
How many campaigns does an e-commerce account need?
Enough to separate budgets that need different targets: typically one or two Shopping campaigns, a brand Search campaign, a non-brand Search campaign and one remarketing campaign. Add more only when a segment needs its own budget or target.
Should I run Performance Max and Standard Shopping together?
Many accounts do, using Standard Shopping for control and Performance Max for extra reach. Keep an eye on overlap so the two do not compete for the same products without a reason.
Why separate brand and non-brand Search?
Brand searches convert at a different rate and cost from non-brand searches. Mixing them hides how your non-brand campaigns really perform.
How often should I review the account structure?
A quarterly review works for most accounts, with a closer look after large catalogue changes or seasonal peaks.
