Every marketing budget has waste in it. Not because marketers are careless, but because spend decisions accumulate over time — a channel that made sense six months ago, a tool nobody questioned at renewal, a campaign that quietly stopped performing but kept getting funded. Before long, you're defending a budget that hasn't been properly scrutinised in years.
A full audit sounds like a big project. It doesn't have to be. With the right prompt, ChatGPT can work through your current spend with you, flag the areas worth questioning, and help you build a case for reallocation, in a single sitting.
Try this prompt:
You are a senior marketing strategist helping me audit and reallocate my current marketing budget.
My details:
- Total monthly budget: [e.g. £20,000]
- Channel breakdown: [list each channel and spend e.g. Paid social: £5k, SEO agency: £3k, Email platform: £500]
- Business goal right now: [e.g. lead generation, brand awareness, retention]
- Performance notes: [e.g. paid social CPL has doubled, SEO traffic is flat, email open rates strong]
- Tools or subscriptions included: [list any platforms, software, or agency retainers]
Review this spend against my goals and give me:
1. WASTED OR UNDERPERFORMING SPEND
- Which line items are most likely wasting budget
- Why (based on the signals provided)
2. CUT / REDUCE / KEEP
- For each line item, label it: Cut, Reduce, Keep, or Double Down
- Give a short justification
3. REALLOCATION PLAN
- Where I should move budget to get better results
- Provide a revised budget split (even if directional)
4. IMPACT PRIORITISATION
- Top 3 changes that would have the biggest impact
- Why these matter most
5. QUESTIONS TO PRESS ON
- Specific, direct questions I should ask my team or agency about each major spend area
Be decisive and practical. Don’t hedge. If data is limited, make the best assumption and state it clearly.
Happy prompting!
