AI Web Search Risks: How Businesses Can Mitigate Data Accuracy Threats

Introduction: The Growing Use of AI for Web Searches in Business

Over half of internet users now rely on artificial intelligence (AI) tools to perform web searches, a trend that is increasingly common in corporate environments. While generative AI (GenAI) offers remarkable efficiency improvements, a recent investigation reveals a troubling gap between user trust in these tools and their actual accuracy. This disparity presents new risks for businesses, especially in areas such as compliance, legal decision-making, and financial management.

The Accuracy Gap in AI-Powered Web Searches

A study conducted by Which? evaluated six leading AI tools — ChatGPT, Google Gemini (standard and AI Overviews), Microsoft Copilot, Meta AI, and Perplexity — by asking 40 questions related to finance, law, and consumer rights.

The results showed that Perplexity led with a 71% accuracy score, closely followed by Google Gemini AI Overviews at 70%. In contrast, Meta AI scored the lowest at 55%, and ChatGPT, despite its popularity, scored only 64%, ranking second-lowest. This highlights a critical issue: popularity does not necessarily equate to reliable output in the GenAI space.

Risks of Inaccurate Financial and Legal Information

The study revealed concerning errors in responses that could expose businesses to risk. For example, when asked about investing a £25,000 ISA allowance, ChatGPT and Microsoft Copilot failed to identify a deliberate mistake in the query regarding statutory limits, potentially leading to advice that breaches HMRC regulations. Conversely, Google Gemini, Meta, and Perplexity detected the error.

Legal teams face similar challenges due to AI’s frequent generalization of regional laws. The tools often overlooked jurisdictional differences between regions such as Scotland and England/Wales. Moreover, AI systems rarely recommend consulting qualified professionals for high-stakes legal or financial issues, sometimes offering advice that could harm a user’s legal standing, such as Gemini’s suggestion to withhold payment in a builder dispute, which experts warned could breach contracts.

Issues with Source Transparency and Data Lineage

Enterprise data governance demands clear information provenance, yet many AI tools provide vague or unreliable source citations. Some responses cited outdated forum posts or links to paid third-party services instead of official government resources. For example, queries about tax codes often returned links to premium refund companies rather than free HMRC tools, risking unnecessary costs.

This opacity complicates vendor due diligence and procurement decisions, as AI-driven recommendations may inadvertently direct businesses towards risky or costly service providers. Technology companies acknowledge these limitations, emphasizing that users bear responsibility for verifying AI outputs.

Provider Responses on Accuracy Challenges

Microsoft characterized its Copilot as a synthesizer of multiple web sources rather than an authoritative source, urging users to verify content accuracy. OpenAI highlighted ongoing industry efforts to improve accuracy, noting that its latest model, GPT-5, represents significant progress in this area.

Strategies to Mitigate AI Business Risks

Rather than banning AI tools—which can drive their use underground—business leaders should adopt governance frameworks designed to ensure data accuracy and reduce operational risks. Recommended approaches include:

• Enforcing Specificity in Prompts: Employees should be trained to provide detailed queries, specifying context such as jurisdiction, to reduce ambiguous or incorrect AI outputs.
• Mandating Source Verification: Users must critically evaluate AI responses by checking cited sources manually and corroborating information across multiple AI platforms, particularly for high-risk topics.
• Operationalizing a “Second Opinion”: AI outputs should be considered preliminary insights rather than definitive answers. For complex financial, legal, or medical decisions, human expert review must remain mandatory.

By implementing these policies, enterprises can balance the efficiency benefits of AI with the need for accuracy and regulatory compliance.

Conclusion: Balancing Efficiency and Risk in AI Web Search

AI tools for web search are evolving and their accuracy is improving, but current limitations mean that overreliance can lead to costly compliance and legal failures. Businesses must embed verification processes into workflows to safely leverage AI-powered research. The difference between harnessing AI to boost efficiency and falling victim to its inaccuracies often lies in robust governance and human oversight.
