Question 1

What rules actually govern advertising, and what does the ASA do?

Accepted Answer

Advertising in the UK sits under a **co-regulatory** system: industry-written codes enforced by a self-regulatory body, **backed by statutory regulators** who can act where self-regulation fails. Understanding the two layers explains why the system has more teeth than it appears to.

**The codes.** The CAP Code covers non-broadcast advertising — websites, social media, email, print, outdoor — and the BCAP Code covers broadcast. A brand's own website and social media **are** advertising for these purposes, which surprises people regularly.

**The ASA** administers them: it investigates complaints, rules on whether an ad breached the code, and publishes rulings. Anyone can complain, **a single complaint is enough** to trigger investigation, and complaints from competitors are treated the same as those from the public.

**The core requirements**, which are short and broad:

**Not misleading.** This is the one most rulings turn on. **Advertisers must hold documentary evidence for objective claims before publishing**, and the burden sits with the advertiser — it is not for the ASA to disprove the claim.

**Not harmful or offensive**, including rules on social responsibility.

**Obviously identifiable as advertising**, which is the basis of influencer disclosure enforcement.

**Specific sector rules** for alcohol, gambling, food and drink high in fat, salt or sugar, financial products, medicines and health claims, and anything directed at children.

**What happens when you breach.** The ASA cannot fine. Its sanctions are **publication of the ruling** — reputationally significant and highly visible in search results — removal of the ad, withdrawal of trade privileges, ad space denial, and paid search ads highlighting the non-compliance. For persistent breaches it **refers to statutory bodies**: Trading Standards, the CMA, Ofcom, or the FCA for financial promotions, and those bodies do have fining powers.

**Other regimes apply simultaneously**, including consumer protection law and specific rules on pricing and subscriptions.

**Copy advice is free** before publication. General information, not legal advice.

Question 2

What is brand safety, and how is it managed?

Accepted Answer

Preventing advertisements appearing alongside content that would damage the brand — and the discipline has matured from crude keyword blocking into something considerably more careful, partly because

Question 3

How do ad blockers affect marketing measurement?

Accepted Answer

They remove a non-random slice of your audience from the data, which distorts more than the raw blocking rate suggests — and the browsers themselves now do much of the blocking, independently of

Question 4

Why does accessibility matter in marketing?

Accepted Answer

Because a substantial proportion of your audience cannot use inaccessible content, the legal position is stricter than most marketers realise, and — practically — accessible content performs better

Question 5

What is out-of-home advertising, and how is it measured?

Accepted Answer

Advertising in public space — billboards, transport, street furniture, retail and increasingly digital screens — and its measurement problem is fundamental: you cannot ask a poster who saw it. The

Question 6

What is ad fraud, and how much of it is there?

Accepted Answer

Any activity that generates payable advertising events — impressions, clicks, installs, conversions — without a genuine human being exposed to the advertisement. Estimates of its scale vary

Question 7

Can you name a competitor in your advertising?

Accepted Answer

Yes — comparative advertising is lawful in the UK and EU, and it is deliberately permitted because comparison helps consumers. But it is permitted only on strict conditions, and failing any one of
