Online Safety Acts are regulatory frameworks that require internet services to protect users from illegal content and shield children from harmful material. These laws transition platforms from passive hosts to active moderators with a legal duty of care. For marketers and SEO practitioners, these acts influence site technical requirements, content moderation strategies, and the visibility of brand assets on third party platforms.
What are Online Safety Acts?
These acts are sets of laws that place responsibility on social media companies, search engines, and other user to user services for the safety of their platforms. The primary goal is to reduce the risk of illegal activity and prevent children from encountering age inappropriate content.
In the United Kingdom, the Online Safety Act 2023 (OSA) leads this regulatory shift. It applies to any service that allows users to interact or post content online, including messaging apps, forums, and search services. In the United States, similar efforts include the Kids Online Safety Act (KOSA) and updates to the Children's Online Privacy Protection Act (COPPA 2.0).
The legislation is often referred to as a "Duty of Care" model. This means platforms must proactively assess risks and implement systems to mitigate harm rather than just reacting to reported content.
Why Online Safety Acts matter
- Financial risk: Non compliance carries massive penalties. Under the UK Act, companies can be fined up to £18 million or 10 percent of qualifying worldwide revenue (Gov.uk).
- Operational changes: Search engines and social platforms must change their algorithms to prioritize safety, which may impact how content is discovered or ranked.
- Ad placement safety: New duties require platforms to remove illegal content like fraud making environments safer for brand advertisements.
- User friction: Requirements for age verification and identity checks can change user behavior and conversion funnels on social platforms and adult sites.
- Global reach: The laws apply based on user location. If a service has a significant number of UK users or targets the UK market, it must comply regardless of where the company is headquartered.
How Online Safety Acts work
The regulatory process generally follows a cycle of assessment, mitigation, and reporting.
- Risk Assessment: Providers must identify the risk of illegal content appearing on their service. This includes considering how their algorithms might disseminate harmful material.
- System Implementation: Platforms must design features to reduce criminal activity. This involves creating easy to use reporting tools and redress mechanisms for users.
- Content Removal: Services have a legal mandate to take down "Priority Offences." These include child sexual abuse, terrorism, fraud, and the sale of illegal weapons or drugs.
- Age Assurance: For services likely to be accessed by children, providers must use robust age checks to prevent minors from seeing "Primary Priority Content" like pornography or material promoting self harm.
- Transparency Reporting: Large platforms (Category 1 services) must publish annual reports about their safety measures and algorithmic impacts.
Types of Online Safety Legislation
Current legislation varies by jurisdiction and the specific harms they target.
| Act Name | Jurisdiction | Primary Target | Key Requirement |
|---|---|---|---|
| Online Safety Act 2023 | United Kingdom | Adults and Children | Duty of care to remove illegal and child-harmful content. |
| KOSA (Proposed) | United States | Minors | Policies to prevent physical, sexual, and financial harms (Davis Wright Tremaine). |
| COPPA 2.0 (Proposed) | United States | Minors under 17 | Prohibits targeted advertising and requires an "eraser button" (Davis Wright Tremaine). |
| App Store Accountability Act | United States (Proposed) | App Users | Obligations for age verification at the store and developer level. |
Best practices for practitioners
- Review content guidelines: Ensure any user generated content (UGC) features on your site have clear moderation policies. This prevents your platform from becoming a host for illegal material.
- Monitor platform updates: Stay informed on how major social networks (Category 1 services) are changing their "terms of service." The Act requires platforms to uphold these terms consistently.
- Audit age gating: If your content is age sensitive, implement robust age assurance. Regulators like Ofcom are already moving toward enforcement for services that fail these checks.
- Update privacy notices: If you are operating in the US under proposed laws like COPPA 2.0, prepare to obtain explicit consent for users aged 13 to 16.
- Verify ad placements: Use platform tools to ensure brand assets do not appear alongside content flagged under the "Priority Offences" list.
Common mistakes
- Mistake: Assuming the Act only applies to social media giants. Fix: Check if your site allows user interaction or content sharing: even small forums or messaging tools are in scope.
- Mistake: Thinking your location shields you from the law. Fix: Evaluate your UK user base. If you target the UK market, the Act applies to you regardless of your physical headquarters (Gov.uk).
- Mistake: Ignoring "legal but harmful" content when targeted at children. Fix: Systems must be in place to prevent children from seeing legal content that encourages eating disorders or dangerous stunts.
- Mistake: Relying on simple "date of birth" self declarations. Fix: Prepare for "robust age checks" as defined by regulator guidance, which may require stricter verification technology.
Examples of Enforcement
UK Cyberflashing Conviction: The first conviction under the new criminal offences occurred in March 2024. This followed the Act making cyberflashing a specific criminal offence (Wikipedia).
Ofcom Fines for Non Compliance: In August 2025, Ofcom fined the anonymous imageboard 4chan £20,000 for alleged non compliance (Wikipedia). In a separate case, an adult website group was fined £1 million for a lack of age checks (Wikipedia).
US Legislative Push: The US House of Representatives recently held a hearing considering 19 new federal digital media bills (Davis Wright Tremaine) aiming to standardize safety rules across the country following various failed state level attempts.
FAQ
What is the deadline for compliance? In the UK, the illegal content duties are already in effect. Services likely to be accessed by children had a deadline of July 24, 2025, to complete their children's risk assessment (Gov.uk). In the US, KOSA would become effective 18 months after enactment.
Does this law affect private messaging? Yes. The UK Act includes online instant messaging services. While there is conflict regarding end to end encryption, the government maintains the power to require services to scan for child pornography and terrorism content when technically feasible.
How does this impact search engine optimization? Search services have a specific legal duty to reduce the risk of users encountering illegal content. This may lead to stricter filtering of certain keywords or categories to comply with "Priority Offences" lists. It also means search engines must provide users with tools to minimize certain types of content.
Can individual users be prosecuted? Yes. The Act introduced new offences that apply directly to individuals, such as sending false information intended to cause non trivial harm (Gov.uk) and epilepsy trolling.
How do platforms determine if a user is from the UK? Platforms typically use IP addresses, but users have responded to these acts by increasing their use of VPN services to circumvent age verification requirements (Wikipedia).
What content is considered "Priority" illegal content? This includes child sexual abuse, terrorism, fraud, inciting violence, illegal immigration assistance, and the sale of illegal drugs or weapons.
What is the "Eraser Button" in US proposals? Under COPPA 2.0, an eraser button allows parents and teens to delete personal information (Davis Wright Tremaine), including data that was republished or resubmitted by another person.
