SEO gets you into Google. GEO gets you into ChatGPT, Perplexity, Claude, and Gemini. The playbooks are different.
Generative Engine Optimization (GEO) means structuring your online presence so that AI-powered search engines — ChatGPT, Perplexity, Claude, Gemini — cite your product when someone asks about your category.
Traditional SEO optimises for Google's ranking algorithm. GEO optimises for AI training data and real-time AI search sources. The signals are different: domain authority matters less; genuine community endorsements matter more.
This is early. Most SaaS founders haven't started thinking about GEO yet. The ones who start now will own the AI search landscape in their category within 12 months.
AI models were trained on the internet, and Reddit is one of the most influential parts of that training data — particularly for product recommendations, tool comparisons, and community opinions.
When ChatGPT recommends a tool, it's drawing on the aggregate of what it's seen people say about that tool in places like Reddit. A product that's been enthusiastically recommended by real users in real conversations has a strong AI recommendation signal.
For live AI search engines like Perplexity, Reddit is even more direct: it often searches Reddit threads in real time and cites them as sources. Your replies today are Perplexity citations tomorrow.
First: be present in the conversations your potential customers are having. That means active participation in the subreddits where they ask about tools, workflows, and problems.
Second: make your product easy for AI to recommend. That means using consistent naming, writing replies that are specific and quotable, and being present across multiple high-authority subreddits.
Third: play a long game. GEO isn't a one-week campaign. It's a six-month commitment to being the most helpful, most consistently present product in your category's corner of Reddit.
Ask ChatGPT and Perplexity the questions your customers would ask. Note which products they recommend and why. This tells you exactly what kind of Reddit presence you need to build to displace them.
Search Reddit for threads that rank in Perplexity's results for your category queries. These threads already have AI attention. A well-placed reply in them carries outsized GEO weight.
The replies that get cited aren't 'check out my product'. They're 'I use this for X, here's how it works, here's what it doesn't do well'. Honest, specific reviews build the kind of trust that AI models encode as recommendations.
Ask ChatGPT and Perplexity about your category every month. Track whether your product appears, what context it appears in, and what the sentiment is. Use this to refine your Reddit strategy.
Redgrow's GEO view shows you the AI citation potential of every subreddit you're monitoring — how frequently it's cited by Perplexity, how often AI models reference threads from it, and which thread types get cited most often.
