WebMax study finds contractors can be invisible to AI shortlists

WebMax Canada says a new study found gaps between online visibility and inclusion in AI-generated contractor recommendations across Victoria, Vancouver, Calgary and Toronto. The August 2026 research tested ChatGPT, Gemini and Claude to see which Canadian businesses made the shortlist and why that may matter for how customers choose contractors.

Why it matters: - WebMax Canada’s study suggests being easy to find on the web does not guarantee a contractor will appear in AI-generated shortlists. - For Canadian businesses, AI visibility now affects whether customers and buyers even see a company during early research. - The finding matters beyond contracting because many industries depend on being shortlisted before a final decision is made.

What happened: - WebMax Canada conducted the Canadian Contractor AI Visibility Study 2026 during August 2026. - The research tested repeated contractor recommendations in Victoria, Vancouver, Calgary and Toronto. - The study covered four trades: plumbing, electrical, home renovation and landscaping. - ChatGPT, Gemini and Claude were the primary platforms compared. - The balanced comparison dataset included 144 AI responses and 720 contractor recommendation positions across 16 city-and-trade combinations. - Each city, trade and platform combination was tested three times in new chats, and the responses were preserved for review. - Susan Jones of WebMax Canada said the team wanted to test the process the way a customer would by asking which local companies an AI service would recommend.

The details: - Each AI service was asked to recommend five businesses. - The services often produced different shortlists, and some companies appeared repeatedly while others appeared on only one platform. - Agreement also varied by city and trade. - The services cited or emphasized different public information when explaining their recommendations. - A separate web-search benchmark found overlap between web visibility and AI visibility, but the two were not the same. - Some established businesses that ranked well in the web-search benchmark did not appear in the primary AI testing. - WebMax Canada manually ran the searches, preserved the original responses, organized the companies that appeared and reviewed recommendation patterns. - The team also compared frequently recommended businesses with legitimate Canadian businesses that were not observed in the primary testing. - The study checked a sample of factual claims made by the AI services about the businesses they recommended. - WebMax Canada says the project was observational, not a controlled experiment, and documents what was observed during testing without proving why a system included or omitted a business.

Between the lines: - The results point to a new kind of competition for local businesses: not just ranking in search, but being selected in AI-generated lists. - A company can have strong web presence and still miss the shortlist when a customer asks an AI tool for recommendations. - The study also suggests AI platforms may be drawing on different signals, since the same query produced different recommendations and different supporting details. - The findings are limited to four contractor categories, so they should not be treated as a universal rule for every Canadian industry.

What's next: - WebMax Canada is not publishing the full company-by-company results, detailed percentages or full platform comparisons in the announcement. - The company says the full findings include platform comparisons, repeat recommendation patterns, city and trade differences, the web-search benchmark, public information cited by AI services, a factual accuracy review, methodology and study limitations. - Full study details are available by request to Canadian businesses, industry organizations, journalists and publications. - Requests for the Canadian Contractor AI Visibility Study 2026 can be made through WebMax.ca or SpottableAI.ca.

The bottom line: - For Canadian contractors, the next visibility gap may be between search results and AI shortlists.
