We're a vertical SaaS in dynamic pricing with 35+ help articles ranked #1 for 'how to optimize [product category] prices in [our platform]' queries. When Gemini answers those exact queries, it cites Shopify and pricing aggregator blogs instead of ours—even though we have schema.org/HowTo + schema.org/DefinedTerm markup for our proprietary pricing algorithms, higher organic rankings, and confirmed 2–3x weekly crawls. We've tested adding schema.org/VideoObject to embedded pricing workflow demos without shift. Before we assume deliberate trust-based deprioritization, what diagnostic test isolates whether Gemini is (A) silently failing to parse our DefinedTerm schema for pricing concepts, (B) weighting pre-training data over current crawl signals, or (C) applying a neutrality heuristic that deprioritizes all vendor-owned commerce content regardless of topical authority?

Build a test cohort: republish 3 identical HowTo articles under a neutral domain + your domain, keep schema identical, monitor Gemini citation patterns over 14 days. If neutral domain gets cited equally, you've isolated a vendor-content bias; if your domain still loses despite identical markup, the issue is pre-training data weight. Also check Gemini's actual crawl via GSC to confirm it's parsing schema—failed parsing usually shows as zero impressions for branded queries.
