How to market to Gen Z with paid media (2026)

Gen Z, born roughly between 1997 and 2012, are aged about 14 to 29 in 2026. To reach them with paid media, go where they spend their time, mainly TikTok, Instagram, YouTube and Snapchat, with ads that look and sound like the content around them. In practice that means vertical video, made with or in the style of creators, tested in volume, and judged on what it adds to sales, not on last-click numbers alone. Remember that part of Gen Z is still under 18, and the rules for advertising to them are much tighter.

This guide covers who you’re really targeting, where to advertise, how to make creative that works, how to measure it, and the rules to follow.

First, split Gen Z in two

“Gen Z” covers both 15-year-olds at school and 28-year-olds with careers and mortgages. For paid media, the most important split is age 18:

• Adults (18 to 29): you can use the full targeting, audiences and ad formats each platform offers, within normal advertising rules.
• Under-18s: the platforms limit what you can do. Meta only uses age and location to decide which ads teens see, and blocks some ad topics for under-18s entirely. Google doesn’t personalise ads for users under 18, including with its own predefined audiences, and restricts sensitive categories such as gambling and weight loss.

If your product is for adults, target 18 and over. If it’s for teenagers, plan for broad targeting and let the creative do the work.

Where to advertise

Gen Z spends a lot of time on video-first apps. Ofcom’s Online Nation research finds YouTube is the UK’s most-used social media service by users and time, and young adults who use TikTok and Snapchat spend around an hour a day on each. Each platform does a different job:

Don’t drop search. Plenty of Gen Z discovery happens on social, but when they’re ready to buy, many still search for your brand or product. Social creates the demand and search often captures it. Our guides to TikTok ads, Meta ads and YouTube ads cover each platform in more depth.

Make creative that fits the feed

On TikTok, Reels and Shorts, polished TV-style ads often get scrolled past. What tends to work:

• Vertical, sound on, captions on. Shoot 9:16, design for sound and add captions for people watching without it. Check that text and logos aren’t hidden by the app’s buttons with our social ad safe zone checker.
• Hook in the first second or two. Open with the problem, the result or a person talking to camera, not your logo.
• People, not products on white. Real people using the product, explaining it, reviewing it or showing a before and after.
• Creators. Creators already know what their audience responds to. You can run their posts as ads from their own account with Spark Ads on TikTok and partnership ads on Instagram and Facebook, which keep the creator’s name and feel.
• Volume and variety. Platforms now use the creative itself to find the right people, so you need a steady flow of different concepts, not one hero ad. See Meta Andromeda: why creative is now your targeting and our creative testing framework.

Don’t try too hard. Forced slang, borrowed memes and fake “relatable” scripts are easy to spot. Clear, honest, useful content from real people usually beats trying to sound young.

Be honest and transparent

Gen Z has grown up surrounded by ads and influencer content, and is quick to notice when something feels fake.

• Label creator content as an ad. The ASA expects paid influencer posts to be obviously identifiable as ads, with a clear label such as “#ad” up front or the platform’s own paid partnership tool. Vague phrases such as “in association with” aren’t enough, and brands are responsible for this too, not just creators. ASA research published in 2026 found only around half of people could confidently tell an influencer post was an ad.
• Show real prices and real reviews. The total price should be clear up front, and reviews must be genuine.
• Make claims you can back up. “Best”, “number one” and “clinically proven” all need evidence under the CAP Code.

Measure what Gen Z ads really add

Social ads to younger audiences often drive sales that last-click reports miss: someone sees a TikTok, then searches for you a week later, or buys in a shop. Judge campaigns on more than in-platform numbers:

• Watch blended results, such as total sales, new customers and MER, alongside platform ROAS.
• Track brand search. Rising searches for your brand name are often a sign social is working.
• Ask customers how they heard about you, with a simple question at checkout.
• Run lift tests where budget allows. Our guide to lift tests explains how, and the incrementality calculator helps size one.

Set up tracking properly too: server-side tracking with the Meta Conversions API and TikTok Events API recovers conversions that browser tracking misses.

The rules to follow

• Under-18s. Meta limits teen ad targeting to age and location and blocks topics such as alcohol, financial products and weight loss for under-18s. Google doesn’t personalise ads for under-18s and restricts categories such as gambling, dating and weight loss.
• Age-restricted products. Alcohol and gambling ads mustn’t be targeted at under-18s, and under the CAP Code the people shown in them mustn’t be, or seem to be, under 25.
• Less healthy food and drink. Since 5 January 2026, paid online ads for identifiable less healthy food and drink products are banned in the UK for businesses with 250 or more employees. Brand ads that don’t show a specific less healthy product are exempt.
• Influencer labelling. Paid creator content must be clearly labelled as an ad, and brands share responsibility with creators.

Common mistakes

1. Treating Gen Z as one audience, when a 16-year-old student and a 27-year-old professional need different products, messages and rules.
2. Running TV ads on TikTok. Repurposed landscape ads with no hook rarely hold attention.
3. One ad, everywhere. Each platform needs creative made for it.
4. Judging on last click, which undervalues social and overvalues brand search.
5. Forgetting the rules on under-18s, labelling and restricted products.

Reaching Gen Z with a subscription app

Subscription apps are one of the most common Gen Z advertisers, and the same rules apply with a few extras:

• Optimise for paying subscribers, not installs. Cheap installs from people who never start a trial look good and cost money. Tell the platforms about trial starts and paid subscriptions so they find more people like your payers.
• Show the app being used. A creator or real user demoing the app on screen, in the first few seconds, beats animated feature lists.
• Lead with the free trial or free tier. Gen Z is price-sensitive and wary of subscriptions they can’t cancel easily, so make the trial and how to cancel clear.
• Consider sending people to the web first. A web sign-up page lets you track and optimise sign-ups more reliably than in-app tracking on iPhones, and can sell the subscription before the download.
• Judge it on retention. Look at how many trial users become paying subscribers and are still paying after a few months, not just the cost per install.

FAQs

What is the best platform to reach Gen Z?

There isn’t one. TikTok and Instagram are strongest for discovery, YouTube for reach and storytelling, Snapchat for younger audiences, and search for capturing people ready to buy. Most brands start with one or two social platforms plus search.

What is the best platform for video advertising to Gen Z?

For discovery, TikTok and Instagram Reels; for reach, YouTube, which Ofcom finds is the UK’s most-used social media service. YouTube Shorts and TikTok in-feed ads use the same vertical video, so one set of creative can run on both. Snapchat adds reach among younger Gen Z.

Which ad formats perform best with Gen Z?

Short, vertical, sound-on video that looks like normal content in the feed: creator-led clips, product demos and reviews, often run as Spark Ads on TikTok or partnership ads on Instagram. Polished TV-style ads and static images tend to get scrolled past, though static ads can still work well for retargeting.

What content do Gen Z prefer in ads?

Real people over brand voice-overs, useful content such as how-tos, demos and honest reviews, humour that fits the platform, and clear prices. Content that feels staged or tries too hard to sound young usually does worse.

Can I target under-18s with ads?

Yes, but with limits. Meta only uses age and location for teens, Google doesn’t personalise ads for under-18s, and products such as alcohol, gambling and many financial products can’t be advertised to them at all.

Do I need influencers to reach Gen Z?

Not always, but creator-style content usually performs better than polished brand ads. You can work with creators and run their posts as Spark Ads or partnership ads, or make creator-style content yourself with real customers and staff.

How do I measure Gen Z social campaigns?

Use platform numbers alongside blended results: total sales, new customers, brand search volume and a “how did you hear about us?” question. Lift tests give the clearest answer where budget allows.

How much should I spend to reach Gen Z?

Enough for each platform’s algorithm to get regular conversions, and enough to keep producing new creative. For one platform plus search, that often means at least £1,500 a month in ad spend, plus the cost of content.

In short

To reach Gen Z with paid media, split by age first, because the rules for under-18s are much tighter. Advertise on TikTok, Instagram, YouTube and Snapchat with vertical, creator-style video tested in volume, keep search running to capture demand, label creator content clearly, and judge results on blended sales and new customers rather than last click alone.
