How Search and Retrieval in LLMs Actually Work
Coalition Technologies

Key insights from Session 1
Recap: Rankscale AI and Coalition Technologies test whether training data or live web search decides which brands AI recommends, using an established US bridal brand across Gemini, Claude, and GPT-5.
- 9:30: Branded prompts look fine either way. The brand scored 100% with and without web search. The real difference shows on non-branded prompts.
- 16:12: Web search can wipe out an established brand. With web search on, non-branded visibility dropped sharply, sometimes to 0%, because the brand had no content for those prompts.
- 13:10: Training-data answers barely cite. GPT-5's five citations without web search were hallucinated. With web search, answers link evidence, but misattribution still happens.
- 17:21: Sentiment freezes at the training cut-off. Negative product reviews in the months before one model's cut-off left the brand at 58% sentiment a year later.
- 20:54: Web search is a content meritocracy. It narrows the field: brands with content tailored to the prompt gain, broad brands without it collapse. Publish or be replaced.
- 24:34: More posts is not more coverage. 98 off-topic blog posts did nothing; a smaller competitor with two targeted posts won the answer.
- 27:12: The year in the URL is a recency signal in the query fan-out.
- 39:32: Self-promotional listicles backfire. Google uses them as a source but drops your brand and recommends the competitors you listed.
