Define your ICP and offer: Who are you targeting, and what's the conversion event? (e.g., demo, download, booked call)
- Rationale: The sharper your ICP and offer, the less you waste on irrelevant clicks.
Set your pipeline goal: How many qualified leads or meetings do you need per month?
- Rationale: Budget should be reverse-engineered from pipeline targets, not gut feel.
Use the benchmarks: Plan for £100–£200 per qualified lead (see verticals below).
- Rationale: These are field-tested numbers from real B2B campaigns, not vendor guesses.
Calculate your starting budget: Leads needed × CPL = starting budget. (e.g., 20 leads × £150 = £3,000)
- Rationale: This keeps you honest—no more "let's just try £500 and hope."
Test, measure, and scale: Start with a 2–4 week pilot. Double down on what works, pause what doesn't.
- Rationale: The best budgets are dynamic. Let the data decide, not your boss's hunch.

Simple ROI Calculator (How to Set Your Budget)

How many qualified leads do you need per month? (e.g., 20)
What's your average close rate? (e.g., 10%)
What's your average deal value? (e.g., £8,000)
What's your target CPL? (use the benchmarks above)

Example:

Need 20 leads × £150 CPL = £3,000/month budget
20 leads × 10% close rate = 2 deals
2 deals × £8,000 = £16,000 pipeline from £3,000 spend
ROI = (£16,000 – £3,000) / £3,000 = 4.3x

Pro Tip: If your ROI is under 2x, revisit your offer, targeting, or creative before scaling spend.

💸 Budget Blunders: What Kills ROI Before You Even Launch

Setting a budget based on "what's left over" instead of pipeline goals.
Chasing "brand awareness" with no conversion target.
Ignoring real benchmarks and hoping for the best.
Not tracking CPL or ROI—flying blind is not a strategy.
Scaling spend before you have a proven winner.
Smart marketers reverse-engineer from pipeline, not leftovers.

💡 Pro Tips from the Trenches

Don't start with "brand awareness" campaigns—optimize for pipeline and qualified leads.
Test 2–3 offers and audiences before scaling budget.
Use retargeting to lower CPL and boost conversion rates.
Review results weekly—pause losers, double down on winners.
Use B2B Ads Assistant to automate targeting, creative, and reporting.
