The Advertising Standards Authority no longer waits for the public to complain before it acts. Its Active Ad Monitoring system, built with AI and machine learning, now scans tens of millions of adverts a year across the internet and flags likely rule-breaks to human investigators — and for the marketing agencies running those campaigns, that changes how fast a mistake gets found.
From complaints to constant scanning
The old model was reactive: someone saw an ad, thought it crossed a line, and reported it. The ASA’s own briefing on the system shows how far that’s shifted. In 2024 the tool reviewed 28 million ads — ten times the year before — with the ASA aiming for around 50 million a year by the end of 2025 and continued growth through 2026. The AI layer does the first pass, sorting huge volumes of live advertising and surfacing the ones most likely to breach the CAP Code; ASA staff then review what it flags before any ruling is made. Nothing is banned by the algorithm alone, but the volume of ads it can put in front of a human investigator is a different order of magnitude to the complaints inbox.
Where the system is looking hardest
The ASA has been explicit that certain categories get the closest attention: alcohol, gambling, financial products, e-cigarettes, influencer marketing, and environmental (“green”) claims. A parallel sweep of influencer content on Instagram and TikTok — the ASA’s second since 2021, covering more than 50,000 posts — found that only around 57% of UK influencer content was clearly disclosed as advertising, with a further 9% carrying a disclosure label too vague to make the commercial nature of the post obvious. That’s the kind of gap active, AI-assisted monitoring is designed to close far faster than a one-off audit ever could.
What it means for agencies running client campaigns
For an agency, the practical shift is speed. A creator post with a buried #ad, a supplement ad making a health claim it can’t back up, or a “carbon neutral” line in a green-energy campaign used to have months, sometimes years, before a complaint might surface it. Under constant AI scanning, that same gap can now be days. Agencies in Westminster, in smaller digital shops around Holbeck, or running client work out of Bingham are all working under the same national rules — this isn’t a London-agency problem, it applies to every UK marketing agency regardless of size or postcode.
What to check before a campaign goes live
- Influencer disclosure — use the platform’s own paid-partnership label, not just a caption hashtag buried after a line break, on every sponsored post.
- Environmental claims — “eco-friendly”, “sustainable” or “carbon neutral” needs evidence behind it, not just on the client’s press release.
- Regulated sectors — alcohol, gambling, finance and vaping ads carry extra rules on audience targeting and content; if a campaign touches any of them, budget time for a compliance check before launch, not after a ruling.
- Ongoing campaigns, not just new ones — the system scans live ads continuously, so a campaign that passed review six months ago can still be picked up if the rules or the ad itself have moved on.
None of this is a reason to slow campaigns down for their own sake — it’s a reason to build the compliance check into the process agencies already run, the same way a final proofread happens before anything goes live.
