The paid social landscape in 2025 is almost unrecognisable compared to 2021 — the year that a certain iOS update changed the economics of digital advertising permanently.
The agencies still selling "precise audience targeting" and "detailed interest segments" are selling a product that no longer works as advertised. Here is what actually does.
Creative Is the Targeting
This is the single most important shift in paid social over the last three years, and many advertisers still have not absorbed it.
When Meta's delivery algorithm lost access to third-party signal data, it leaned more heavily on on-platform engagement signals to determine who sees what. The practical consequence: a well-crafted piece of creative that resonates with your ideal customer will, over time, self-select toward that audience. The algorithm watches who engages, who buys, who watches to the end — and serves the ad to more people like them.
Broad targeting with excellent creative now frequently outperforms narrow targeting with mediocre creative. The targeting is happening — it is just happening inside the creative, not inside the audience settings.
What this means in practice: invest the majority of your paid social budget into creative production and testing, not into audience research. If your creative speaks with specificity and precision to a real pain point, the algorithm will find your customer.
The First Three Seconds
On every major platform — Meta, TikTok, YouTube — the first three seconds of a video ad determine whether it will be served at scale. The algorithm measures the "hook rate" (what percentage of people watch past the first three seconds) and uses it as a primary quality signal.
A 40% hook rate is considered good. Above 50% is exceptional. Below 25% and the ad will rarely exit the learning phase.
The implication: the most valuable three seconds of any campaign budget is not the closing offer — it is the opening hook. A common mistake is to spend all creative energy on the product or the CTA and treat the opening as an afterthought. The opening is the entire ad as far as the algorithm is concerned.
Hooks that consistently perform: a counterintuitive statement, an unresolved tension, a specific claim with a number in it ("47% of e-commerce brands make this mistake"), or a visual that requires explanation.
What Broad Actually Means Now
Running "broad" on Meta in 2025 does not mean untargeted. It means trusting the algorithm to find your audience rather than specifying it yourself. The data suggests this approach delivers lower CPMs and, for most accounts, better CAC at scale — because the algorithm's data set is larger and fresher than any audience a human can construct in Ads Manager.
This works best when: your creative is strong, your pixel has sufficient conversion data (minimum 50 purchase events per week), and your landing page experience is consistent with the ad promise.
It works poorly when: you are launching a new account with no pixel history, your product has an unusual or restricted audience, or your creative is generic enough that the algorithm cannot identify a signal.
The Platform Mix
TikTok has proven its performance credentials and is no longer optional for brands targeting under-40 audiences. Its creative language is distinct from Meta — native-feeling, unpolished by comparison, driven by audio and trend participation — and brands that try to repurpose Meta creatives for TikTok typically see poor results.
YouTube remains underutilised by most SMB advertisers. The audience is older and higher-income than TikTok; the intent signals from search adjacency are valuable; and the competition for placement is lower than Meta in most verticals.
Pinterest and LinkedIn each have specific use cases. Pinterest for home, fashion, and lifestyle brands targeting female purchasers. LinkedIn for B2B lead generation where the cost-per-lead can be justified by deal size.
The playbook in 2025 is not "be on every platform." It is: choose the one or two platforms where your customer actually makes purchase decisions, master the creative language of those platforms, and invest deeply rather than broadly.
