AI web search risks: Mitigating business data accuracy threats

Over half of us now use AI to search the web, but the stubbornly low data accuracy of widespread instruments creates new business dangers.

While generative AI (GenAI) affords plain effectivity beneficial properties, a brand new investigation highlights a disparity between person belief and technical accuracy that poses particular dangers to company compliance, authorized standing, and monetary planning.

For the C-suite, the adoption of those instruments represents a traditional ‘shadow IT’ problem. According to a survey of 4,189 UK adults carried out in September 2025, round a 3rd of customers imagine AI is already extra necessary to them than customary web looking. If staff belief these instruments for private queries, they’re virtually definitely using them for business analysis.

The investigation, carried out by Which?, means that unverified reliance on these platforms could possibly be pricey. Around half of AI customers report trusting the knowledge they obtain to a ‘affordable’ or ‘nice’ extent. Yet, trying on the granularity of the responses offered by AI fashions, that belief is usually misplaced.

The accuracy hole when utilizing AI to search the web

The research examined six main instruments – ChatGPT, Google Gemini (each customary and ‘AI Overviews’), Microsoft Copilot, Meta AI, and Perplexity – throughout 40 widespread questions spanning finance, regulation, and client rights.

Perplexity achieved the very best whole rating at 71 p.c, carefully adopted by Google Gemini AI Overviews at 70 p.c. In distinction, Meta scored the bottom at 55 p.c. ChatGPT, regardless of its widespread adoption, acquired a complete rating of 64 p.c, making it the second-lowest performer among the many instruments examined. This disconnect between market dominance and dependable output underlines the hazard of assuming reputation equals efficiency within the GenAI house.

However, the investigation revealed that every one of those AI instruments incessantly misinterpret data or offered incomplete recommendation that would pose critical business dangers. For monetary officers and authorized departments, the character of those errors is especially regarding.

When requested the best way to make investments a £25,000 annual ISA allowance, each ChatGPT and Copilot didn’t determine a deliberate error within the immediate concerning the statutory restrict. Instead of correcting the determine, they provided recommendation that doubtlessly risked breaching HMRC guidelines.

While Gemini, Meta, and Perplexity efficiently recognized the error, the inconsistency throughout platforms necessitates a rigorous “human-in-the-loop” protocol for any business course of involving AI to make sure accuracy.

For authorized groups, the tendency of AI to generalise regional laws when utilizing it for web search presents a definite business danger. The testing discovered it widespread for instruments to misconceive that authorized statutes usually differ between UK areas, equivalent to Scotland versus England and Wales.

Furthermore, the investigation highlighted an moral hole in how these fashions deal with high-stakes queries. On authorized and monetary issues, the instruments occasionally suggested customers to seek the advice of a registered skilled. For instance, when queried a couple of dispute with a builder, Gemini suggested withholding cost; a tactic that specialists famous may place a person in breach of contract and weaken their authorized place.

This “overconfident recommendation” creates operational hazards. If an worker depends on an AI for preliminary compliance checks or contract evaluate with out verifying the jurisdiction or authorized nuance, the organisation may face regulatory publicity.

Source transparency points

A main concern for enterprise data governance is the lineage of knowledge. The investigation discovered that AI search instruments usually bear a excessive accountability to be clear, but incessantly cited sources that have been obscure, non-existent, or have doubtful accuracy, equivalent to outdated discussion board threads. This opacity can result in monetary inefficiency.

In one check concerning tax codes, ChatGPT and Perplexity offered hyperlinks to premium tax-refund firms slightly than directing the person to the free official HMRC software. These third-party providers are sometimes characterised by excessive charges.

In a business procurement context, such algorithmic bias from AI instruments when utilizing them for web search may result in pointless vendor spend or engagement with service suppliers that pose a excessive danger on account of not assembly company due diligence requirements.

The main expertise suppliers acknowledge these limitations, putting the burden of verification firmly on the person—and, by extension, the enterprise.

A Microsoft spokesperson emphasised that their software acts as a synthesiser slightly than an authoritative supply. “Copilot solutions questions by distilling data from a number of web sources right into a single response,” the corporate famous, including that they “encourage folks to confirm the accuracy of content material.”

OpenAI, responding to the findings, stated: “Improving accuracy is one thing the entire trade’s engaged on. We’re making good progress and our newest default mannequin, GPT-5, is the neatest and most correct we’ve constructed.”

Mitigating AI business danger by way of coverage and workflow

For business leaders, the trail ahead is to not ban AI instruments – which frequently will increase by driving utilization additional into the shadows – however to implement sturdy governance frameworks to make sure the accuracy of their output when convey used for web search:

• Enforce specificity in prompts: The investigation notes that AI continues to be studying to interpret prompts. Corporate coaching ought to emphasise that obscure queries yield dangerous data. If an worker is researching laws, they have to specify the jurisdiction (e.g., “authorized guidelines for England and Wales”) slightly than assuming the software will infer the context.

• Mandate supply verification: Trusting a single output is operationally unsound. Employees should demand to see sources and verify them manually. The research means that for high-risk subjects, customers ought to confirm findings throughout a number of AI instruments or “double supply” the knowledge. Tools like Google’s Gemini AI Overviews, which permit customers to evaluate offered web hyperlinks straight, carried out barely higher in scoring as a result of they facilitated this verification course of.

• Operationalise the “second opinion”: At this stage of technical maturity, GenAI outputs needs to be considered as only one opinion amongst many. For advanced points involving finance, regulation, or medical data, AI lacks the power to completely comprehend nuance. Enterprise coverage should dictate that skilled human recommendation stays the ultimate arbiter for choices with real-world penalties.

The AI instruments are evolving and their web search accuracy is steadily bettering, however because the investigation concludes, counting on them an excessive amount of proper now may show pricey. For the enterprise, the distinction between a business effectivity achieve from AI and a compliance failure danger lies within the verification course of.
