One SEO Week Sponsor Is Dominating AI Visibility. It’s Not Who You’d Expect.

Why It Matters

AI‑driven search is becoming a primary influence on buyer research, so brands that secure credible, third‑party citations can outperform larger competitors in the AI memory layer.

Key Takeaways

• Siteimprove secured 16 of 24 brand‑owned citations, leading AI visibility
• 58% of ChatGPT citations came from sources brands don’t control
• AI visibility diverges from market size; smaller firms can outrank giants
• G2 report shows 71% of buyers use AI chatbots for software research
• Ross Simmonds will teach AI‑search branding at SEO Week April 29

Pulse Analysis

The Foundation team ran a controlled audit of ChatGPT’s answers to a single prompt about each of the 15 SEO Week 2026 sponsors. By logging every URL the model cited, they captured 220 citations and classified them into brand‑owned, third‑party editorial, review sites, and user‑generated content. This approach reveals exactly which digital assets feed the large‑language‑model’s knowledge graph, offering brands a rare glimpse into the “memory layer” that powers AI‑driven search results. The data set, though small, mirrors the broader shift toward conversational discovery in B2B buying.

The results upended expectations. Siteimprove dominated brand‑owned citations with 16 of 24 URLs, while 58 % of all references originated from domains the companies do not control. High‑authority institutions such as Northwestern and the Nevada state government appeared alongside the brand, signaling deep integration that outweighs sheer marketing spend. For competitors like SimilarWeb, Semrush, and Ahrefs, lower on‑domain presence suggests that AI visibility is not a simple function of market share. Marketers must therefore prioritize earned placements in reputable third‑party sites to shape LLM outputs.

These insights dovetail with G2’s Answer Economy Report, which found 71 % of B2B decision‑makers now rely on AI chatbots for software research and that two‑thirds change vendors after AI guidance. The convergence means AI visibility can directly influence purchase pipelines, making proactive LLM audits essential. At SEO Week, Ross Simmonds will walk attendees through a playbook for embedding brand language into the AI memory layer, from content frameworks to Reddit ad strategies. Companies that act now can convert AI‑driven curiosity into measurable revenue.
