SVZ AI search visibility study Collected September 17, 2026, approximately 05:36 to 05:41 UTC. 33 prompts; 26 discovery, 4 brand, 3 comparison. 3 planned providers; 99 planned pairs. 66 valid API answers from OpenAI GPT-5.4 web-search and Perplexity Sonar; 33 Gemini/OpenRouter observations unavailable after access failure (32 blocked locally). One observation per prompt/provider. Consumer UI behavior, geography and personalization were not measured or controlled. CSV true/false flags reflect configured name matching and returned svz.io-domain sources, not recommendation quality or sentence-level attribution. Empty flags on unavailable rows mean unknown, not false. A Webflow staging URL returned for one OpenAI answer was not counted as a production svz.io-domain source. The svz_related_returned_urls column preserves relevant returned URLs, including that staging URL. The study did not qualify for an aggregate cross-provider score. No causal claim, trend comparison with prior methods, current visibility score, revenue result or inferred consumer behavior. The accompanying 37-article audit found none of its individual post URLs in the returned source lists, within this sample only. Publisher: SVZ.
