Artificial intelligence (AI) is now a core part of eCommerce marketing, driving everything from AI-generated product descriptions to automated ads and personalised campaigns.
Recent guidance from the AANA, increased ACCC scrutiny of digital advertising, and clear messaging from Ad Standards confirm that using AI does not reduce your legal obligations.
In this article, our eCommerce lawyers explain why these tools, while powerful, are creating new legal risks for online businesses.
Key Takeaways
AI-generated ads can create real legal liability under Australian Consumer Law
Businesses remain legally responsible for AI outputs used in marketing
Misleading, exaggerated or unsubstantiated claims remain high-risk
Ad Standards can require AI ads to be amended or removed
Pre-publication legal review is now a critical risk-management step
Why AI Advertising Creates Legal Exposure
New Technology, Existing Laws
AI advertising operates within an established legal framework that includes:
Australian Consumer Law (misleading or deceptive conduct)
AANA Code of Ethics
Ad Standards determinations
Digital platform advertising policies
Privacy and data protection obligations
The key legal test is not how an ad is created, but how a reasonable consumer is likely to interpret it.
While Australian law allows a degree of promotional “puffery”, this is limited to obvious, opinion-based exaggeration – AI-generated claims that appear factual, comparative or measurable can quickly fall outside this protection and create legal risk.
Legal tip: If an AI-generated statement could influence a consumer’s purchasing decision as a matter of fact, it is unlikely to be treated as harmless puffery.
Ethical AI Guidelines: AANA’s Role in Shaping Legal Risk
The AANA’s Industry Guidelines on the Ethical Use of AI in Marketing are not legislation, but they provide a clear indication of how industry bodies (and potentially regulators) expect AI to be used in advertising.
From a legal perspective, the guidelines reinforce the need for:
Transparency where AI materially affects marketing content
Human oversight of AI-generated outputs
Accountability for claims generated at scale
Responsible use of consumer data and targeting
Failure to align with these principles increases the likelihood of complaints to Ad Standards and regulatory scrutiny, particularly where AI-generated advertising lacks context or oversight.
For businesses in regulated sectors such as health and wellness, AI-generated claims demand even closer scrutiny – learn more about advertising rules for health and wellness products to avoid costly missteps.
ACCC Oversight and Digital Advertising Trends
The ACCC continues to closely monitor digital platforms and services, including how businesses advertise online using automated systems and algorithms.
For e-commerce businesses, this scrutiny is particularly relevant where:
AI influences pricing, discounts or urgency claims
Advertising appears native or indistinguishable from content
Consumers are targeted using behavioural or transactional data
Algorithms amplify claims at scale
Although the ACCC does not approve advertising content, its focus on consumer harm and digital markets means businesses should expect increasing attention on how AI-driven advertising affects consumer decision-making.
Legal tip: The more automated and scaled your advertising is, the more important it is to ensure claims are accurate, clear and defensible.
Ad Standards: “New Tech, Same Rules”
Ad Standards has been clear that existing advertising rules apply regardless of the technology used. AI-generated ads must still comply with the AANA Code of Ethics and meet community expectations around honesty, transparency and fairness.
Ad Standards can:
Investigate complaints about digital and AI-generated advertising
Require non-compliant ads to be modified or removed
Publish determinations that may impact brand reputation
For e-commerce businesses, this reinforces the importance of reviewing AI-generated marketing before it goes live.
Where E-Commerce Businesses Commonly Face Risk
In practice, legal exposure often arises from:
AI-generated product descriptions that overstate performance
Automated comparisons with competitors
Dynamic pricing or discount claims without clear conditions
Influencer or affiliate content amplified by AI tools
Environmental, health or “best in market” claims lacking substantiation
Even unintentional inaccuracies can amount to misleading or deceptive conduct when repeated across multiple platforms.
Checklist: Reviewing AI-Generated Advertising
Before publishing AI-assisted marketing, businesses should ask:
- Have all AI-generated claims been reviewed by a human decision-maker?
- Could a reasonable consumer interpret the claim as factual?
- Are comparisons, endorsements or guarantees supported by evidence?
- Is advertising clearly identifiable as advertising?
- Does the content align with AANA and Ad Standards requirements?
- Has a legal or compliance review occurred for higher-risk campaigns?
To ensure your entire e-commerce operation is legally sound, see our guide on the legal essentials for e-commerce businesses for practical tips on compliance beyond advertising.
Real Life Example: AI Ads and Liability
An e-commerce retailer uses AI to generate ad copy stating that its product “outperforms leading brands at half the price”. The claim is published across social media and product listings without verification by the business.
Potential consequences may include:
A complaint to Ad Standards requiring removal
ACCC investigation for misleading or deceptive conduct
Competitor challenges
Platform account suspension
A targeted legal review by experienced eCommerce lawyers would likely have identified the comparative claim as high-risk and required evidence or revised wording before publication.
Frequently Asked Questions
Who is responsible for AI-generated advertising content?
The business publishing the advertisement is legally responsible, regardless of whether the content was created by AI.
Does Australian Consumer Law apply to AI ads?
Yes. The ACL applies to all advertising, including AI-assisted and automated marketing.
Since the Australian Consumer Law applies fully to online advertising and e-commerce, it’s essential to understand how ACL protections affect your business – see our article on whether Australian Consumer Law applies to online business for full context.
Can i be required to take down my AI ads?
Yes, regulatory bodies (like Ad Standards) can require non-compliant advertising to be amended or removed.
Is legal review required for all marketing materials?
While it’s not a legal requirement, it is strongly recommended for AI-generated or high-volume campaigns to reduce your business’s legal risk.
Does AI increase regulatory risk?
Yes, if not used responsibly. AI can increase your business’s exposure by providing inaccurate or misleading claims.
If your business uses AI or automation in advertising, the risk is not theoretical – it is commercial and immediate. Contact Prosper Law’s eCommerce lawyers to review your marketing materials and reduce the risk of AI-driven advertising liability.
