Paid social platforms don’t all do the same job. Picking one because a competitor is on it is how budgets get wasted fast. Meta reaches a different audience to TikTok. TikTok reaches a different audience to LinkedIn. What actually matters is matching the platform to what you’re trying to achieve, not which one has the most hype attached to it this month.
Meta Is Still the Default Starting Point
Facebook and Instagram together still give you the widest reach of any platform on this list, and the targeting data built up over a decade and a half of pixel tracking, interest data and lookalike audiences is hard to match anywhere else. Meta suits almost any objective. Cold awareness campaigns, warm retargeting, direct response conversions all run comfortably on the same platform, which is exactly why most businesses start here. The trade-off is cost. CPMs have climbed steadily for years now, more advertisers piling into the same auction every quarter. Default doesn’t mean cheap. Not anymore.
Is Meta Advertising Still Worth It in 2026?
For most businesses, yes. Treat it as a baseline though, not a guaranteed win. The targeting maturity and audience scale are still unmatched. Most customers still use Facebook or Instagram in some form, so Meta remains the platform most likely to reach them at every stage of the funnel. What’s actually changed is the assumption that Meta alone is enough. The businesses winning on Meta right now are usually running it alongside something else, not betting everything on one account.
TikTok Reaches an Audience Meta Increasingly Can’t
TikTok skews younger. Its algorithm rewards content that looks native to the platform, not an obvious repurposed ad. Take a polished product shot that’s been performing well on Instagram and drop it straight into TikTok, and it can fall completely flat. The feed expects something that belongs there, not an interruption. Different platform, different creative job, not a second place to dump the same assets. Where TikTok actually earns its place is awareness. Top of funnel discovery. Introducing a brand to people who’ve never heard of it, rather than closing a sale in that same session.
LinkedIn Is Built for B2B, Not Volume
Nobody advertises on LinkedIn for a bargain. Cost per click routinely sits well above Meta and TikTok, and that’s the price of targeting by job title, company size and industry rather than broad interest categories. For a business selling to other businesses, particularly anything with a considered, higher value sale, that precision is worth the premium. For a low cost ecommerce product chasing volume, LinkedIn is almost always the wrong platform, whatever the account manager on your last call suggested.
Why Is LinkedIn Advertising So Expensive?
Because you’re paying for professional intent, not just an impression. LinkedIn’s user base is smaller than Meta or TikTok’s, and the advertiser pool competing for that same professional audience is intensely focused, since B2B budgets chase the same job titles and company profiles again and again. Small audience, high competition, high stated intent. That combination pushes cost per click up in a way no amount of campaign optimisation fully undoes.
Snapchat and the Smaller Platforms
Snapchat still holds a genuinely loyal younger audience in the UK, particularly the under 25 bracket, but its overall scale is a fraction of TikTok’s. It’s rarely worth building a strategy around on its own. Where it earns a place is as a targeted addition once you already know your core audience skews young and you’ve got the creative capacity to support a third or fourth platform properly. Pinterest sits in a similar bracket. Useful if you’re selling into home, fashion or weddings specifically, but not somewhere most businesses should lead with.
Which Paid Social Platform Should I Start With?
Choosing between paid social platforms starts with your primary customer, not the other way round. Selling a physical product with broad appeal? Lead with Meta. The reach and targeting maturity give you the best chance of finding buyers quickly. Selling a B2B service into a specific job title or industry, LinkedIn is worth the extra cost, because the precision saves wasted spend that a cheaper platform would burn through anyway. Building a brand on visual identity for a genuinely younger audience is TikTok’s job, and the creative needs building for that platform specifically. Borrowed assets from somewhere else won’t do the work.
Audience Targeting Looks Different on Every Platform
The targeting options on each platform aren’t interchangeable, and building the same audience definition three times across three platforms usually produces three different results. We’ve gone into this properly in our piece on paid social competitor and audience targeting, because getting the audience right on each individual platform matters as much as picking the right one in the first place.
Why Betting Everything on One Platform Is a Mistake
Putting your entire budget behind one paid social platform means your entire performance depends on one algorithm, one auction, one set of rising costs. When that platform’s CPMs spike, and every major platform has had a period where they did, you’ve got nowhere else to shift spend. A considered approach across multiple paid social platforms spreads that risk and usually reaches more of your actual audience too, since almost nobody’s customer base lives entirely on a single app.
Where Paid Social Fits Alongside Everything Else
Paid social rarely works best in complete isolation from your other marketing either. It plays a specific role feeding awareness and consideration that other channels, particularly PPC, can pick up and convert once someone’s already searching with intent. We look at exactly this kind of cross channel relationship as part of our wider PPC work, because a paid social campaign that’s building demand and a search campaign that’s capturing it should be planned together, not run as two separate accounts that never talk to each other.
Should I Advertise on Multiple Platforms at Once?
Eventually, yes. Not on day one though. Start with the platform that best matches your objective and audience. Prove it can work first. Add a second platform once you actually understand what’s converting, not before. Spreading a small budget across four platforms from the start usually means none of them get enough spend to leave the learning phase, and you end up with four sets of mediocre data instead of one set of good data.
Choosing between paid social platforms isn’t really a one-time decision. It’s an ongoing judgement call as audiences shift, costs move and new formats appear, and getting it right consistently is exactly where a paid social agency earns its keep rather than just running whichever platform was recommended on a podcast last month.
