Large language models lean heavily on Reddit. If your brand is absent from those threads, you are skipping the highest-leverage GEO play of 2026.
Look closely at the citations under any Perplexity or ChatGPT answer about software, tools, or buying decisions. Reddit threads dominate.
Why? Because LLMs were trained heavily on Reddit, and because Reddit content is exactly what the models want to summarize: real people, real opinions, real comparisons.
The implication is uncomfortable for traditional marketing teams: your perfectly polished landing page matters less than a single thread on r/SaaS where someone asked "what do you use?" and ten people answered.
You don't game Reddit. You participate honestly. But you absolutely need to know which threads mention you, which mention competitors, and which threads are about to shape the next generation of AI answers.
