TikTok Ads Agency: Make Advertising That Does Not Look Like It
Castle produces and runs TikTok advertising built for the platform — native short-form creative, Spark Ads through real accounts, and Shop campaigns that turn attention into orders.
A specialist TikTok Ads agency
The platform punishes anything that feels like an advert.
TikTok is the one channel where production value can actively hurt you. A polished brand film gets scrolled; a slightly rough demo with a strong first second sells. That inverts how most brands and most agencies are set up to make work.
Castle produces TikTok creative natively — vertical, sound-on, hook-first — and runs it through Spark Ads from real accounts so it carries the credibility of a post rather than the tone of a campaign. Then we test relentlessly, because on TikTok creative fatigue arrives in weeks, not quarters.
What’s included
What’s included in our TikTok Ads management
A managed TikTok programme: creative production and creator sourcing, campaign management, Shop integration and the testing cadence the platform demands.
-
Native creative production
Vertical, sound-on video made for TikTok rather than trimmed from something else. Hook in the first second, payoff before the third, captions that work with the sound off, and enough variants to keep the account fed.
-
Creator and UGC sourcing
We brief and manage creators to produce authentic content at volume, then run the best of it as paid. Creator-made ads consistently outperform brand-made ones here, and they give you a content library beyond the ad account.
-
Spark Ads through real accounts
Running ads as boosted organic posts, from your handle or a creator’s, so they inherit the profile, comments and follows. It reads as content, and the engagement stays on the post rather than evaporating with the campaign.
-
TikTok Shop and Video Shopping
Catalogue setup, product tagging and Shop campaigns so the distance between watching and buying is a tap. For the right products this collapses the funnel entirely.
-
High-tempo creative testing
New concepts into the account every week, judged on hook retention and cost per acquisition rather than on likes. Fatigue is managed by refresh rate, which is the discipline most accounts lack.
-
Full-funnel measurement
Pixel and Events API setup, view-through and assisted conversion reporting, and blended performance alongside platform figures — because TikTok drives a lot of demand that converts elsewhere.
Why TikTok
Why do I need a TikTok Ads agency?
TikTok is a creative supply problem before it is a media problem. Accounts stall because they cannot produce enough native video, not because the targeting was wrong — and most brands and traditional agencies are not built to make short-form at that tempo.
The platform also rewards a tone most marketing teams find uncomfortable. Ads that acknowledge they are ads, creators talking plainly to camera, imperfect footage: these outperform brand-safe polish, and getting sign-off on that internally is its own piece of work.
Measurement needs care too. A lot of TikTok’s effect shows up as branded search and direct traffic days later, so a last-click view will consistently undervalue it and the channel gets cut just as it starts working.
A specialist agency brings the production line, the creator relationships and the measurement framework together, so the channel is judged on what it actually contributes.
On TikTok the algorithm finds the audience from who responds to the video, so the asset does the qualifying that audience settings do elsewhere. That is why our TikTok work is resourced as a production schedule with media buying attached, rather than the other way round.
Formats
How we buy TikTok
The formats are not interchangeable. Each one suits a different point in the relationship with the viewer.
-
In-Feed Ads
The default buy: your video in the For You feed. Lives or dies on the first second, which is why we test hooks separately from the rest of the edit.
-
Spark Ads
Ads served as real posts from a real handle, carrying profile, comments and follows. Higher trust, better engagement, and the social proof stays attached.
-
Creator partnerships
Briefed creators making content in their own voice, then amplified as paid. The most reliable way to get volume that does not feel like advertising.
-
TikTok Shop
In-app checkout with product tagging and live shopping. For impulse-priced products it removes the entire journey to your site.
-
Retargeting
Video-view and engagement audiences re-approached with a different hook rather than the same ad again, which is what makes warm TikTok traffic economic.
We run Spark Ads wherever we can, because an ad that lives on a real profile keeps earning after the budget stops.
Industry fit
TikTok strategies built for your category
TikTok suits some categories immediately and others only with the right angle. Visually demonstrable products sell almost natively; considered and regulated purchases need education-led content and a longer measurement window. We are straight with you about which you are before spending anything. Categories we work with include:
- Ecommerce
- Beauty
- Food and drink
- Health and wellbeing
- Fashion
- Home and garden
- Fitness
- Education
- Travel
- Subscription

Costs on TikTok are still below the equivalent reach on Meta in many categories, and that gap closes as more advertisers arrive. The brands building a creative library now are buying attention at a discount.
Short-form has also become the default way products are discovered by younger buyers, and increasingly by everyone else. Search is where they confirm a decision; short-form is frequently where they first heard of you.
The creative you build transfers. Native vertical video works on Reels, Shorts and paid social generally, so a TikTok production line raises performance across the whole paid mix rather than serving one channel.
And the barrier is lower than it looks. Creator-made content at volume costs a fraction of traditional production, which is exactly what the platform rewards.
Polish gets scrolled. On TikTok the winning asset usually looks like someone just filmed it.
Our expertise
Why choose Castle as your TikTok Ads agency
We have our own video and design team, so short-form production happens in-house at the cadence TikTok needs instead of waiting on an external studio.
We already run TikTok alongside Facebook, Instagram, Twitter and Snapchat as part of paid social programmes that have generated hundreds of thousands of pounds a month for clients, so it is planned as part of a mix rather than sold as a novelty.
And we will tell you if your product is wrong for the platform. Some are, and spending your budget finding that out slowly is not a service worth buying.
FAQ
TikTok Ads frequently asked questions
It suits products you can show, explain or demonstrate, and audiences who are on the platform. It is harder for narrow B2B and heavily regulated offers, though education-led content can work there with a longer view. We will give you an honest answer before you spend, including if the answer is no.
Enough to test several creative concepts properly rather than one, since creative is the variable that matters. In practice that means a budget which can run multiple concepts to statistical clarity within a few weeks. We size it from your product economics.
We do, with our in-house video and design team, plus briefed creators where a genuine outside voice performs better. You end up with a content library you can also use organically rather than assets that only exist inside the ad account.
Spark Ads run your campaign as a real post from a real account, so the ad carries the profile, comments, likes and follows. They read as content rather than advertising, engagement accrues to the post, and that social proof keeps working after the campaign ends.
Weeks rather than months. Fatigue is much faster than on Meta, so we plan a continuous production schedule instead of a launch batch, and judge concepts on hook retention as well as cost per acquisition.
Increasingly, yes — the age profile has broadened considerably and it is no longer a teenage platform. That said, we would not recommend it as your primary channel for an older demographic when the same budget on Meta or search would reach them more directly.
Pixel and Events API for the direct path, then view-through and assisted conversions, branded search lift and blended performance for the rest. Judging TikTok purely on last-click will undervalue it every time, so we set the measurement framework before launch.
Yes — catalogue setup, product tagging, Shop campaigns and Video Shopping Ads. For impulse-priced products it is often the strongest way to run the channel, because it removes the journey to your site altogether.
