What’s the best way to prompt ChatGPT for business?

ROI answers

ChatGPT, as of early 2026, functions best when provided with highly specific, role-defined prompts – essentially, you’re instructing it to *be* a particular expert and deliver a specific output. The more context and constraints you provide, the more relevant and useful the response will be for your business needs.

  • Persona Assignment: Begin prompts with “Act as a…” followed by a role (e.g., “Act as a digital marketing strategist specialising in the Australian retail sector”).
  • Format Specification: Clearly define the desired output format (e.g., “Provide a table comparing the costs of Google Ads vs. Facebook Ads for a small business in Melbourne”).
  • Data Inclusion: Feed ChatGPT relevant data about your business – target audience demographics, existing marketing materials, competitor analysis – to personalise responses.
  • Constraint Setting: Limit the scope of the response (e.g., “Generate five social media post ideas, each under 120 characters, focused on promoting our new winter sale”).

In 2026, current systems include advanced data privacy features, crucial for Australian businesses adhering to the updated Privacy Act. ChatGPT now features improved natural language understanding, allowing for more nuanced prompts. However, always verify generated content for factual accuracy and compliance with Australian Consumer Law, particularly regarding advertising claims. Remember, ChatGPT’s knowledge cut-off still exists, so it won’t have real-time data on market trends without you providing it.
