Perplexity and ChatGPT form recommendations from public online content. Weekly expert posts strengthen brand and Google — and feed those systems as a bonus.
Key Takeaways
Perplexity and ChatGPT do not invent local experts from thin air. They analyse public online content — including the posts you publish on Google Business Profile and elsewhere. If you never post, there is little for those systems to work with. Brand and Google get the first benefit of weekly expertise content; AI recommendations are a bonus of the same library. Here is how that process works.
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.
You know you should post every week. You never have the time. Weekly Authority builds 26 or 52 weeks of practitioner-level posts and images — you upload one file to Publer (or a similar scheduler) and it runs from there. Built for businesses that want content Perplexity and ChatGPT can cite — after brand and Google are solid. Brand and Google first; AI readiness as a bonus.
