Google Display Network Case Study: How Remarketing Helped Drive $1.9M in Revenue at a 708% ROI
Image ads, continuous A/B testing, and a disciplined remarketing campaign turned Display Network visibility into measurable, trackable purchases.
Quick summary: In this Google Display Network case study, a supplement manufacturer achieved a 708% return on ad spend and an estimated $1.9 million in revenue, by combining continuously tested Display image ads, keyword-researched Search campaigns, and a remarketing strategy that brought hesitant visitors back to complete a purchase.
Introduction
This Google Display Network case study looks at a supplement manufacturer specializing in weight gain products. The goal going in was simple to state and hard to deliver: increase online visibility in a way that actually improved return on investment, not just traffic for its own sake.
Our Strategy
Display Network image ads, continuously tested
The core of the strategy was spreading visibility across the Google Display Network using image ads and content ad variations, tested continuously against each other rather than launched once and left alone. Ongoing A/B testing is what separated this from a typical “set it and forget it” display campaign.
Search, built on real keyword research
Display wasn’t the only channel. A Search campaign was built on top of thorough keyword research, capturing the more direct, higher-intent searches that Display alone wouldn’t reach.
Remarketing to recover hesitant visitors
Not everyone buys on the first visit. A remarketing campaign brought people back to the site who had shown interest but hadn’t purchased yet, keeping the brand in front of warm prospects instead of losing that traffic for good.
The Results
Visibility increased quickly, and it translated into sales almost immediately, not just impressions.
Key results at a glance:
- 708.22% value to cost ratio, roughly $7 in revenue for every $1 spent
- Estimated total revenue exceeding $1.9 million since the strategy began
- Directly trackable (1-per-click) conversions grew 245%, from 490 to 1,689
- View-through conversions grew 854%, from 59 to 563, revealing revenue influence that click-only tracking would have missed entirely
- Total campaign scale: 972,087 clicks and over 112 million impressions, at an average cost of $9.96 per conversion
Conversions tracked directly to a click grew 245%, from 490 to 1,689.
View-through conversions, purchases influenced by an ad the visitor saw but didn’t click, grew 854%.
What Business Owners Can Learn
- The Google Display Network can drive real revenue, not just impressions, when the creative is continuously tested rather than launched once and forgotten.
- Click-based conversion tracking misses a real category of buyers. View-through conversions capture people who see an ad, don’t click, and purchase later on their own.
- Search and Display work better together than either does alone. Search captures direct intent. Display builds the broader visibility that creates that intent in the first place.
- Remarketing recovers revenue that would otherwise be lost the moment a visitor leaves without buying.
- Any revenue estimate built on assumptions, like average purchase price applied to view-through conversions, should be disclosed as an estimate, not presented as a confirmed number.
Frequently Asked Questions
What is the Google Display Network and how is it different from Search ads?
Search ads show up when someone actively types a query into Google. The Display Network instead shows image and content-based ads across a huge network of partner websites and apps, reaching people while they’re browsing, not actively searching. In this case study, Display Network ads with continuously A/B tested creative were the primary driver of new visibility, complemented by Search campaigns built from thorough keyword research.
What are view-through conversions, and why do they matter?
A view-through conversion happens when someone sees a display ad, doesn’t click it, but later goes on to make a purchase on their own. Standard conversion tracking often misses this entirely because it only counts conversions tied to a direct click. In this case study, view-through conversions grew 854% and represented a meaningful share of estimated revenue that would have been invisible to click-only reporting.
What’s a good ROI for Display Network advertising?
It varies significantly by product margin, price point, and industry, so there’s no single benchmark that applies everywhere. In this case study, the account achieved a value to cost ratio of 708.22%, meaning roughly $7 in revenue for every $1 spent, driven by continuous ad testing, thorough keyword research on the Search side, and a disciplined remarketing campaign working together rather than any single tactic alone.
How does remarketing help ecommerce sales?
Most visitors don’t purchase on their first visit to a site. Remarketing shows ads specifically to people who have already visited but haven’t bought yet, keeping the brand in front of warm prospects instead of letting that traffic disappear for good. In this case study, remarketing was a core part of the strategy alongside Display and Search, and is a meaningful contributor to the conversion growth seen across the account.
Final Thoughts
None of this came from one channel working in isolation. It came from Display building visibility, Search capturing direct intent, and remarketing recovering the visitors who needed a second look before buying, three channels working as one system rather than three separate campaigns.
If you’re not sure whether your own advertising is missing revenue that click-only tracking can’t see, that’s exactly the kind of question a Competitive Marketing Analysis is built to answer. It’s free, it takes a real look at where you stand, and there’s no pressure attached either way.
