Ofcom: UK traffic to porn sites has fallen by almost a third since introducing new age verification rules in July; Aylo says Pornhub's traffic has fallen by 77%
British government applied tougher checks on adult sites in July to stop children accessing content
Context & Ripple Effects
Ofcom’s result extends the early traffic drop measured soon after the rules began, when major compliant sites saw sharp UK declines in the first weeks of age-check enforcement. The policy had been designed around robust checks that could include ID, age estimation, or payment-card methods under Ofcom’s age-assurance framework.
The aggregate decline matters because it separates lower measured access from the question of where users go instead. Earlier coverage found non-compliant sites gaining UK users while compliant services lost them as enforcement created a compliance gap.
First-order effects
- UK adult-site operators using age checks face lower measured traffic; Aylo reports a particularly steep 77% decline for Pornhub.
- Ofcom has evidence that the July rules are reducing recorded visits to pornography sites, advancing the policy’s child-access objective.
Second-order effects
- The uneven burden gives non-compliant sites a near-term traffic advantage, increasing the commercial cost for platforms that implement robust checks.
- The traffic losses strengthen the case for Ofcom to focus enforcement on operators that have not adopted effective verification, rather than treating aggregate traffic as the sole outcome.
Third-order effects
- If enforcement becomes more consistent across sites, adult-content distribution in the UK may shift toward providers able to absorb verification, privacy, and compliance costs.
- The results illustrate a broader access-control trade-off: rules can reduce measured access at regulated services, but their effectiveness depends on limiting substitution to less-regulated alternatives.
The trend: The UK is testing whether platform-level age assurance can become an enforceable access-control layer rather than a compliance burden borne only by the largest services.
