YouTube Ads for E-commerce: The Overlooked Channel

If you’re running paid media for an e-commerce brand, it’s worth paying close attention to where budgets are quietly shifting. While most marketers are still crowding the usual suspects: Meta, TikTok, Google Search – the savvier brands are moving a step ahead.

They’re leaning into YouTube.

And not in a small way. In the final quarter of 2024, YouTube ad spend rose by 13.8%. That’s not a temporary jump- it’s the start of a meaningful shift in the digital ad landscape. For brands looking to diversify their media mix and unlock more scalable acquisition, YouTube is fast becoming a critical part of the strategy.

Here’s why.

YouTube is built around intent

Let’s start with user behaviour. TikTok and Instagram are excellent for entertainment, but users aren’t there to make decisions, they’re there to scroll.

YouTube is different. It’s a platform people actively use to solve problems, do research or evaluate purchases. They type in specific queries. They watch product comparisons, how-tos and reviews. As an advertiser, that’s an opportunity to place your brand right next to high-intent moments.

You’re not interrupting; you’re showing up exactly where your product naturally fits into the conversation. And when you’re promoting a product that requires a bit of thought before purchase, this makes a huge difference to results.

Time spent on YouTube isn’t just higher-it’s higher quality

Here’s how monthly average watch time stacks up:

• TikTok: 9.5 hours
• Instagram: 12 hours
• YouTube: 23.1 hours

And around 70% of that YouTube viewing is happening on TV screens.

That’s a completely different level of attention. It’s not someone scrolling on their phone between tasks. It’s leaned-back, living room-style viewing-more like traditional TV than mobile social media.

For brands, that means you get a longer window to make your case. It also means more emotional connection, stronger recall and a far better shot at moving someone from awareness to purchase.

YouTube’s audience is older-and they spend more

One of the myths we hear all the time is that YouTube is a Gen Z channel. In reality, the majority of meaningful conversions are coming from older segments.

Here’s what the actual audience split looks like:

• 25–34: 20%
• 35–44: 15%
• 45–54: 11%

These are prime-age buyers with disposable income-ideal for brands selling products in the £50–£100+ range. If you’ve been running campaigns on TikTok or Instagram and struggling with low AOV or inconsistent conversion rates, YouTube could be the answer.

YouTube leverages the power of Google’s data ecosystem

This is where YouTube becomes more than just a video platform-it becomes a strategic growth engine.

Because YouTube ads run through Google Ads, you can use all the first-party search data you’ve already collected. That includes the search queries converting on Google, the shopping campaigns driving revenue, and the audiences showing the strongest intent.

You can:

• Build YouTube audiences based on proven keyword performance
• Repurpose winning creative from Meta or TikTok
• Track performance across the entire funnel with much more visibility

It’s a rare advantage. You’re not starting from scratch-you’re building on a foundation that already works.

A real-world result from our agency

We recently helped a consumer brand test YouTube as a new acquisition channel. They started with a modest £1,000 weekly spend. Within 90 days, we had scaled to £13,000 per week-and their ROAS actually improved during that ramp-up.

We followed a layered structure:

1. Start with high-performing Google Search and Shopping
2. Add retargeting to re-engage recent visitors
3. Introduce Performance Max for broader reach
4. Scale with YouTube Demand Gen and in-feed video ads

Because we already had the funnel in place, adding YouTube allowed us to amplify what was working-not guess our way through a new channel.

Which YouTube campaign types to use for e-commerce

Here’s the part most “YouTube is underpriced” pieces skip: how you actually buy the inventory has changed. If you last looked at YouTube a couple of years ago, you’ll remember Video Action Campaigns (VAC) and TrueView for Action. Both are gone. Google stopped letting advertisers create new Video Action Campaigns in April 2025 and began automatically upgrading existing ones to Demand Gen from July 2025, with the final campaigns migrated in early 2026. So the naming in a lot of older guides is now out of date.

For an e-commerce brand today, the two campaign types that matter are Demand Gen and Performance Max.

Demand Gen is the successor to Video Action Campaigns and the workhorse for YouTube. It runs across YouTube in-stream (the skippable ads before and during videos), YouTube in-feed (in the Home feed, Search results and watch-next), YouTube Shorts, plus Discover and Gmail. You get channel controls to decide precisely where you serve, and if you connect a Google Merchant Center account you can attach a product feed so shoppable products sit alongside the video.

Performance Max casts wider still, automatically serving across YouTube, Search, Shopping, Display, Discover, Gmail and Maps from a single campaign. It’s the broad-reach layer rather than a YouTube-specific tool, but it does put your products in front of YouTube audiences.

YouTube campaign type	Best funnel stage	What it optimises for	Best-fit e-commerce use
Demand Gen (in-stream)	Upper-to-mid	Conversions / conversion value	Skippable video ads that introduce the product and build intent
Demand Gen (in-feed)	Mid	Considered clicks and views	Reaching people actively browsing and comparing
Demand Gen (Shorts)	Upper-to-mid	Conversions / reach	Short vertical creative for lower-funnel discovery
Performance Max	Full funnel	Conversion value (blended)	Broad, automated reach across Google’s surfaces including YouTube

How to structure and launch a YouTube e-commerce campaign

You don’t need a big production budget to start, but you do need the plumbing in place. A straightforward launch runs like this:

1. Link Google Ads to your YouTube channel. Your video ads live as (usually unlisted) uploads on your channel, so the account link has to exist before anything can run.
2. Connect Google Merchant Center. If you sell physical products, link your Merchant Center account and attach the product feed so shoppable products can appear beneath and beside your Demand Gen video.
3. Build audience signals from your Search data. Feed the campaign your best-converting search terms, your customer lists and your remarketing audiences. This is the Google-data advantage we talked about earlier, applied at setup.
4. Choose the right bidding strategy. For sales, use Target ROAS if you have enough conversion history to hit a value target, or Target CPA if you’re optimising to a cost-per-acquisition. Maximise conversions or maximise conversion value are sensible starting points while the campaign learns.
5. Set your channel controls. Decide whether you want in-stream, in-feed, Shorts, or a mix, and whether to include Discover and Gmail.
6. Upload creative in multiple aspect ratios (see below) and launch.

What your YouTube ad creative needs

Creative is where e-commerce YouTube campaigns are won or lost. A few rules that hold up:

• Hook in the first five seconds. In-stream ads are skippable after five seconds, so the product, the problem it solves and a reason to keep watching all need to land before then.
• Cover the aspect ratios. Google’s Demand Gen specs accept 16:9 (horizontal), 1:1 (square), 4:5 and 9:16 (vertical). Supply 9:16 for Shorts and vertical placements, and 16:9 for standard in-stream, rather than letting one ratio get letterboxed everywhere.
• Mind the length. Demand Gen videos can be as short as five seconds, but anything under 10 seconds won’t serve on YouTube in-stream, and Google recommends 15 seconds or more to maximise reach across formats. A tighter 10-15 second cut for Shorts and a slightly longer in-stream version is a sensible pairing.
• Finish with a clear CTA and end card. Tell the viewer exactly what to do and pair it with the product and price. If you’re running a product feed, let the shoppable cards carry the click.

How to measure YouTube’s true contribution

The most common objection to YouTube is “does it actually work, or is it just claiming credit?” Fair question, and the answer is to measure it properly rather than judging YouTube on last-click alone:

• View-through conversions capture people who saw the ad, didn’t click, then came back and bought. Video’s contribution is often heavily view-through, so ignoring it undercounts YouTube badly.
• Blended ROAS across the whole account is the number that matters. If overall revenue and efficiency improve as you add YouTube spend, the channel is pulling its weight even if its in-platform ROAS looks softer than Search.
• Incrementality tests (a geo split or a conversion lift study) are the cleanest way to prove YouTube is adding sales rather than harvesting ones you’d have won anyway. Understanding the difference between claimed and incremental return sits at the heart of sensible media-buying unit economics.

A realistic budget and ramp

You don’t need a five-figure budget to begin. The bigger constraint is giving the campaign enough conversions to exit the learning phase, so start with a weekly spend that generates a steady flow of conversions rather than a trickle, and hold your nerve while the algorithm settles.

In the case above we opened at £1,000 a week and scaled to £13,000 within 90 days, but the exact numbers matter less than the shape: increase budget in measured steps (roughly 20-30% at a time rather than doubling overnight), watch blended ROAS as you go, and pull back if efficiency slips rather than chasing volume off a cliff. Expect CPA to be choppy in the first couple of weeks and to settle as the data builds.

The opportunity is now-but it won’t last forever

Right now, YouTube ads are still underpriced relative to the value they deliver. You’re getting a combination of intent, attention and targeting that few other platforms can offer-and you’re doing it at CPCs that haven’t yet caught up to the demand.

If your brand is looking for the next real growth lever-and you’ve already tapped into Meta or Search-YouTube should be high on your list.

It’s not about abandoning what’s worked. It’s about building on it. And if you get your structure right, YouTube doesn’t just generate views. It drives profitable, scalable revenue.

Frequently asked questions

Do YouTube ads work for e-commerce?

Yes, when they’re measured properly. YouTube reaches people in a leaned-back, higher-attention environment and, because it runs through Google Ads, it can use your existing search and shopping data to target high-intent audiences. The key is to judge it on view-through conversions and blended ROAS across the account rather than last-click alone, since much of video’s contribution shows up as assisted rather than direct sales.

Which YouTube campaign type should e-commerce brands use?

Demand Gen is the main one. It replaced Video Action Campaigns in 2025 and runs across YouTube in-stream, in-feed and Shorts, plus Discover and Gmail, with product feeds from Google Merchant Center. Performance Max is the broader, fully automated layer that includes YouTube alongside Search, Shopping and Display.

Are Video Action Campaigns still available?

No. Google stopped allowing new Video Action Campaigns in April 2025 and automatically upgraded existing ones to Demand Gen through 2025 and into early 2026. If you’re following an older guide that mentions Video Action Campaigns or TrueView for Action, the equivalent today is Demand Gen.

What budget do you need to start with YouTube ads?

There’s no fixed minimum, but you want enough weekly spend to generate a steady flow of conversions so the campaign can exit the learning phase. Start at a level that produces consistent conversions, scale in measured 20-30% steps, and watch blended ROAS as you increase budget.

What creative do you need for YouTube e-commerce ads?

Video that hooks in the first five seconds, supplied in multiple aspect ratios (16:9 for standard in-stream, 9:16 for Shorts and vertical placements), ideally 15 seconds or longer to serve across all formats, and finished with a clear call to action and end card. If you attach a product feed, shoppable cards can carry the click through to your site.
