AI search tools like Perplexity and ChatGPT analyse online content to form business recommendations. Here is how that process works and what it means for your content strategy.
Key Takeaways
Perplexity and ChatGPT approach business recommendations differently, but both rely fundamentally on the same thing: the quality, depth, and consistency of a business's online content footprint.
Perplexity is a real-time AI search engine — it actively searches the web when responding to queries. When someone asks Perplexity to recommend a local business, it performs live searches, retrieves current content, synthesises the information, and provides a cited recommendation. That differs from the training-data pattern described in how ChatGPT chooses which businesses to recommend.
This means Perplexity is highly responsive to recent content. A business that has published strong, specific content in the past few months will be better positioned than one whose content is years old. Perplexity cites its sources, which means businesses whose content is retrieved appear explicitly in the recommendation with attribution.
ChatGPT's base model relies on training data with a knowledge cutoff. When forming recommendations without web access, it draws on patterns in what it learned during training. ChatGPT with web browsing enabled behaves more like Perplexity, actively searching for current information — a shift that fits the broader GEO picture.
Despite their technical differences, both reward the same fundamental content characteristics: genuine expertise signals, specificity, geographic anchoring, and consistency over time. A sustained pattern of weekly publication builds the kind of persistent, multi-signal authority that both systems recognise and trust.
