What Recruiters Need to Know About TikTok This Year

TikTok reaches around 24.9 million adults in the UK, roughly 136 million in the US and 10.2 million in Australia. That’s somewhere between a third and two-fifths of the adult population in each of those markets. The audience sits mainly in early- to mid-career stages, and because the For You Page hands out reach based on interest rather than follower count, a brand-new account can get in front of thousands of people. For recruitment, search and staffing businesses, the honest answer is that TikTok is a candidate channel, not a client one. There’s no sourced example of a recruitment business winning new client work through TikTok, and no verified UK, US, or Australia return-on-investment benchmark for the sector. The people who sign off recruitment spend aren’t concentrated on the platform. So if you hire at volume for entry- to mid-level roles, it’s worth testing with a small, defined budget of around 300 to 500 pounds over a fortnight, measuring your own cost per lead rather than relying on anyone else’s numbers. If you’re targeting senior or executive people, put that time into LinkedIn, your email list, and direct outreach instead. This post covers the audience data, what the algorithm rewards in 2026, what a test costs in time and money, and four questions to help you decide either way. What You Will Learn in This Post • Who’s really on TikTok in the UK, the US and Australia, and what those numbers mean for the roles you fill • Why the change of ownership in January 2026 removes the one objection that stopped a lot of recruiters from looking at the platform at all • What the algorithm rewards now, and why a brand new account with no followers can still get real reach • Why TikTok can get you candidates but there’s no evidence it will get you clients • The difference between attracting candidates and winning clients, and why mixing the two up costs you money • What a proper test costs in time and money, and four questions that’ll tell you whether to run one at all I know what some of you are thinking. TikTok is for dancing. It’s not for a serious recruitment business. My clients aren’t on there. Some of you will be right about that. And I want to say up front, you have my permission to walk away from this one. Not every channel is for every company, and part of my job is helping you say no with confidence rather than adding another thing to a list you’re already struggling to get through. But it’s a fair question, so let’s answer it properly. Here’s where I’ve landed after going through the research. TikTok can get you candidates. I couldn’t find any evidence that it will get you clients. That’s the short version. The rest of this post is why, and what you should do about it. What Changed in 2026 Let me start with what’s shifted, because if you looked at TikTok a year or two ago and backed away, your reason might not apply anymore. TikTok is a short-form video app owned by the Chinese technology company ByteDance. It launched internationally in September 2017. In January 2026, its US operations were sold to a new, majority American-owned entity called TikTok USDS Joint Venture LLC, led by Oracle, Silver Lake and Abu Dhabi’s MGX. They hold 80.1 per cent between them, with ByteDance keeping 19.9 per cent. The deal closed on 22 and 23 January 2026. Why does that matter to you? Because for years, the objection I heard most about TikTok had nothing to do with the audience. It was the risk that the whole thing might disappear overnight in the US. Hard to build a plan on that. That question has now been answered. I’ll be straight with you, though. Some legal commentators, including at Harvard Law School, argue the data and influence questions haven’t been fully settled. So not every concern is gone. It’s that the one that made planning impossible has. If you parked TikTok because of that, it’s worth another look. Who’s Really on TikTok in Your Market These are TikTok’s own advertising reach estimates for adults, which are the most current, source-dated data available. • UK: around 24.9 million adults, roughly 36 per cent of the population • US: around 136 million adults, roughly 39 per cent. Estimates vary between sources from 136 million up to 153 million, so treat it as a range • Australia: around 10.2 million adults, roughly 37.5 per cent So in all three of the markets most of you work in, somewhere between a third and two-fifths of the adult population is reachable on this platform. That isn’t a niche. Which is why it’s worth making a proper decision about, rather than dismissing it because of what you assume is on there. Now, the make-up of that audience is what matters for you. In the UK, TikTok’s adult audience is around 62 per cent female, which is a big difference from...
