Choosing the right TikTok agency for your strategy

The number of agencies claiming TikTok expertise has grown dramatically in the last two years. Most of them are social media agencies that have added TikTok to their service list without meaningfully changing how they work. A few of them are genuine TikTok specialists. The difference in results between the two is significant – and it’s not always obvious which is which from a pitch deck.

This guide gives you a framework for evaluating TikTok agencies properly: what credentials actually matter, what questions to ask in a meeting, and what red flags to watch for.

It’s written by Nonsensical – a TikTok-first agency that has been working on the platform since 2020 – so you should read it with appropriate scepticism. But the criteria we’re outlining are objective, and they’d disqualify us too if we didn’t meet them.

Start with platform credentials

Are they an Official TikTok Marketing Partner?

TikTok’s official partner programme is the clearest baseline credential available. Agencies with Official TikTok Marketing Partner status have been verified by TikTok directly, have demonstrated platform expertise, and have direct access to TikTok’s support teams and early product information.

This doesn’t guarantee results, plenty of excellent TikTok work has been done by agencies without partner status, but the absence of partner status from an agency claiming deep TikTok expertise is worth questioning.

Are they an Official TikTok Shop Partner?

If e-commerce or TikTok Shop is part of your brief, ask specifically about TikTok Shop partner status. It’s a separate accreditation from the marketing partner badge, and there are very few UK agencies that hold both.

An agency without Shop partner status managing your TikTok Shop account won’t have the same platform access, support relationships or early feature visibility as one that does.

How long have they been on TikTok?

TikTok launched in the UK in 2018. Agencies that started working on the platform in 2020 or earlier have seen the platform go through multiple eras – from dance trends to social shows, from basic organic content to full-funnel commerce.

That institutional knowledge is hard to shortcut. An agency that added TikTok to its service list in 2023 simply hasn’t accumulated the same depth of platform understanding.

Look for evidence of genuine platform understanding

Do they run their own TikTok accounts?

This is one of the most telling signals. Agencies that run their own TikTok communities, not just client accounts, have skin in the game.

They’re learning from the platform daily, experimenting with formats that aren’t client-funded, and building the kind of real-time platform knowledge that only comes from actually being on TikTok constantly.

At Nonsensical we run our own TikTok communities – including Endless Mythology (381K followers, 46M views) and Endless Pride – alongside client accounts. That gives us daily insight into what the algorithm is doing, what formats are emerging, and what content is resonating. Agencies without owned channels don’t have this.

Can they explain the algorithm in plain terms?

Ask any prospective agency to explain how TikTok’s algorithm works.

A genuine TikTok specialist should be able to explain the difference between the For You Page and the Following feed, how watch time and completion rate influence distribution, why shares are weighted more heavily than likes, and how the algorithm tests content in waves before pushing it to a wider audience.

Vague answers about ‘engagement’ and ‘the algorithm liking consistency’ are a red flag.

Do they understand the difference between TikTok and other platforms?

Ask how they’d approach content differently for TikTok versus Instagram Reels.

If the answer is primarily about format ratios and caption length rather than the fundamental difference in how content is discovered and what native TikTok creative looks like, you’re talking to a social media generalist rather than a TikTok specialist.

Evaluate their case studies properly

Every TikTok agency will present case studies. Here’s how to evaluate them beyond the headline numbers:

Are the results specific and attributed?

Vague claims like ‘we grew a client’s following by 200%’ are meaningless without context. Look for specific client names, specific metrics (views, followers, engagement rate, conversion data), and a clear description of what the agency actually did. Our case study for CarCloud shows 100,000+ app installs at 60p CPI – specific, attributed, and verifiable.

Do they have cases across multiple service types?

A strong TikTok agency should have results across organic content, paid advertising and – if relevant to you – TikTok Shop. An agency with only organic case studies may not have the paid media expertise to run your ads effectively. An agency with only paid cases may lack the content capability to create what you need.

Are the case studies recent?

TikTok in 2022 was a different platform to TikTok in 2026. A

lgorithm changes, format evolution, the rise of TikTok Shop, and the maturation of the audience have all changed what effective TikTok marketing looks like.

Case studies more than two years old should be treated as historical context, not evidence of current capability.

For reference, our insight reports and webinars are updated regularly – they’re a good indicator of whether an agency is tracking the platform actively or relying on old knowledge.

The questions to ask in a pitch meeting

Beyond credentials and case studies, these are the questions that will tell you the most about whether an agency truly understands TikTok:

• What’s your process for staying on top of TikTok trends? How quickly can you turn around trend content for a client?

The right answer involves a specific process. A regular internal session reviewing the platform, a clear brief-to-publish timeline. Our answer is a 24–48 hour turnaround.

If an agency doesn’t have a specific answer, they’re not operating with the speed TikTok requires. Our webinar on being reactive on TikTok explains why speed is so fundamental.

• How do you approach creative strategy for a new client? What’s the process before you post the first piece of content?

Look for answers that mention audience research, identifying the right ‘Tok’ or niche, competitive analysis, and a period of testing before optimising. Agencies that jump straight to content production without this foundation are guessing.

• What does your reporting cover, and how frequently will we get it?

Strong TikTok reporting goes beyond views and follower growth. It should cover watch time, completion rate, save rate, share rate, and, for paid activity – CPM, CPC, ROAS and creative-level performance. Weekly reporting cadence is standard for active campaigns. Monthly is too slow to optimise effectively.

• How do you handle TikTok Shop if it becomes relevant?

Even if TikTok Shop isn’t your immediate priority, understanding an agency’s Shop capability tells you a lot about their platform depth. The answer should cover affiliate recruitment, live shopping strategy and Shop ads, not just listing optimisation. Our TikTok Shop page explains exactly how we approach this.

• Who will actually be working on our account day to day?

This is the question most brands forget to ask and most regret not asking. In many agencies, the senior people who pitch are not the people who do the work.

Ask who your day-to-day contact will be, what their TikTok experience is, and how many other accounts they’re managing simultaneously.

Red flags to watch for

• They describe TikTok as ‘similar to Instagram Reels’ or lead with format specs rather than content strategy
• Their case studies are all views and follower counts with no commercial outcomes (sales, installs, leads)
• They can’t name a specific trend or format that’s currently working on TikTok
• They propose to repurpose your existing video content rather than create natively for the platform
• They have no owned TikTok presence – no brand account, no communities, nothing
• They guarantee specific follower or view numbers – no legitimate agency can guarantee algorithmic outcomes
• Their retainer structure doesn’t include dedicated creative production time – TikTok without content creation isn’t TikTok

What should a TikTok agency cost?

Retainer pricing varies significantly based on scope but be cautious of pricing that feels too low. 

TikTok requires genuine creative investment – agencies charging sub-£1,500/month are either cutting corners on creative, spreading account managers too thin, or both.

If you’re trying to evaluate whether to bring in an agency or build the capability in-house, our TikTok training programme is worth considering. 

t’s designed specifically for in-house teams who want to develop real platform expertise rather than outsourcing everything.

The honest version

We’re a TikTok agency, so take our criteria with the appropriate pinch of salt. What we’d say is this: the questions above are genuinely useful for separating agencies that understand TikTok deeply from those that don’t. 

Apply them to us too. Ask us about our owned communities, our process, our recent case studies, and who’ll be on your account.

We’d rather lose a pitch to a client who asked hard questions than win one from a client who’s going to be disappointed in six months.
