GuestPost.UK Playbook Tip

The biggest ChatGPT shortcut is choosing the right mode before writing the perfect prompt. A current factual question may need Search, a complex investigation may need Deep Research, and long-running work may be better organised inside Projects or delegated through agentic features.

GuestPost.UK Prompt Formula

A Better Way to Write ChatGPT Prompts

Most weak ChatGPT outputs begin with vague instructions. A reusable prompt structure makes results more consistent across writing, SEO, research, coding, study and business work.

01 Role Define the expertise or perspective ChatGPT should adopt.
02 Goal State exactly what you want the final result to achieve.
03 Context Give the background, audience, inputs or source material.
04 Constraints Add limits such as tone, scope, language, length or exclusions.
05 Output Specify the structure, format, table, bullets or final deliverable.
06 Check Ask ChatGPT to flag assumptions, gaps or uncertain claims.
Example: SEO Research Prompt Put the formula together
ROLE: Act as an SEO strategist.
GOAL: Find content opportunities for my website.
CONTEXT: UK audience, topic = link building, commercial + informational intent.
CONSTRAINTS: Avoid duplicate-intent keywords and unrealistic broad terms.
OUTPUT: Table with keyword, intent, cluster, page type and priority.
CHECK: Flag assumptions and explain why each cluster belongs together.

Power Prompt Shortcut

Stop Asking ChatGPT Vague Questions

You usually do not need an extremely long prompt. You need enough context to remove ambiguity and enough structure to tell ChatGPT what a useful result looks like.

Weak Prompt

Too vague

Write an article about link building.
  • No audience defined
  • No search intent
  • No purpose or desired outcome
  • No format or quality constraints
Power Prompt

Clear enough to act on

Before writing, identify the search intent for "link building", the core subtopics users expect, likely questions and content gaps. Then create a UK-focused article outline for an SEO-savvy business audience. Flag anything that requires factual verification.
  • Defines the task sequence
  • Specifies audience and market
  • Requests analysis before drafting
  • Includes a verification instruction
