Home Depot’s AI Citation Lead Is 16.5%, Not 28.9%
A widely shared 28.9% AI search figure does not match 5WPR’s Home Services & Improvement AI Visibility Index, which estimates Home Depot’s AI citation share at 16.5%.
Home Depot leads the buying-query rankings in 5WPR’s 2026 Home Services & Improvement AI Visibility Index, but its estimated AI citation share is 16.5%, not 28.9%. The distinction matters because the two figures are not interchangeable measures of retailer visibility in AI-generated answers.
The 28.9% claim circulated in an X post describing Home Depot as the ecommerce leader in AI search across analyzed platforms. However, the most directly relevant source for that specific comparison, 5WPR’s Home Services & Improvement AI Visibility Index 2026, places Home Depot first with an estimated 16.5% AI citation share. Lowe’s follows at 13.5%, while Ace Hardware is listed at 6.5%.
This is not simply a correction of a single percentage. It is a reminder that AI search measurements need their metric, dataset, category, and methodology stated together. A percentage drawn from AI Overview mentions, domain concentration, conventional search visibility, or another study cannot be presented as AI citation share without evidence that both measurements cover the same sources and calculation method.
What the index measures
5WPR describes its index as a directional view of which brands AI systems cite for home services and improvement-related questions. It tracks more than 60 homeowner prompts during Q2 2026 across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. The resulting percentages are estimates, not precise market-share measurements.
That methodology gives the ranking useful scope, but also clear boundaries. It reflects performance within the report’s selected prompts, engines, and home services and improvement category. It does not establish a universal measure of all ecommerce AI search visibility, nor does it prove that a cited brand will receive a particular amount of traffic, revenue, or customer conversion.
The report’s buying-query results show a concentrated competitive picture:
- Home Depot ranks first with an estimated 16.5% AI citation share.
- Lowe’s ranks second with an estimated 13.5% share.
- Ace Hardware ranks third with an estimated 6.5% share.
- The index separates buying-query visibility from hiring-query visibility, where brands such as Angi, Thumbtack, and TaskRabbit lead.
| Brand or query surface | Position in the index | Estimated AI citation share or leading role |
|---|---|---|
| Home Depot | First in buying queries | 16.5% |
| Lowe’s | Second in buying queries | 13.5% |
| Ace Hardware | Third in buying queries | 6.5% |
| Hiring queries | Led by service-marketplace brands | Angi, Thumbtack, and TaskRabbit are identified as leaders |
Why the metric needs careful interpretation
AI citation share is a measure of how often a brand appears in answers generated by the platforms and prompts covered by the index. It is not automatically equivalent to a retailer’s ecommerce market share, search ranking, AI Overview mention rate, or authority across every product category.
The unsupported 28.9% figure may be connected to a different AI visibility dataset or measure, including research about the concentration of mentions among top domains. Even if a figure is valid within its original study, it should not be relabeled as Home Depot’s citation share in 5WPR’s index. Doing so changes the meaning of the number and can overstate what the available evidence shows.
For retailers, the practical takeaway is that AI visibility reporting should be evaluated as a measurement framework, not as a standalone score. Before using a percentage in strategy discussions, teams should confirm which engines were tested, which prompts were included, whether the result concerns citations or mentions, and whether it applies to product buying, service hiring, or another user intent.
The split between buying and hiring surfaces is particularly relevant. Home improvement retailers may be prominent in answers to product-oriented questions, while marketplaces and service platforms can be more visible when users ask who can perform a job. These are adjacent customer journeys, but they are not the same competitive query set.
Organizations assessing AI answer visibility can work with Scalevise on AI visibility measurement, content strategy, and workflow design that connect reporting definitions to practical implementation decisions.
What retailers should watch next
The index offers a snapshot for Q2 2026 rather than a permanent ranking. AI systems, their retrieval behavior, and the content they cite can change over time. Future measurements may also differ if they use different prompt sets, categories, regions, engines, or definitions of a citation.
That makes repeatable measurement more valuable than isolated claims. A useful assessment should preserve the underlying prompts, platform coverage, reporting period, and calculation method so that changes can be interpreted rather than merely announced. It should also keep buying and hiring journeys separate when the underlying user question calls for different types of businesses.
