Short answer
A B2B media plan should fit on one page and answer six questions: who you need to reach (accounts and people), how often, through which channel and why, what each line costs, how spend will be paced, and which KPI decides whether a line gets more money. Build it from the account list, not from last year's budget, and write the decision rules down before launch.
The six questions a plan must answer
- Who: target accounts by tier, and people per account by role.
- How often: impressions per person per week or month, and the share you want to reach three or more times.
- Where and why: one job per channel line.
- How much: budget per line, from impressions × CPM or clicks × CPC.
- How it's paced: flight dates, daily budgets, the platform's overspend rules.
- What decides: the KPI per line and the rule that moves money.
The one-page template
| Line | Job | Audience | Volume | Budget a month | KPI and rule |
|---|---|---|---|---|---|
| ChatGPT ads | Catch in-market buyers | Decision-stage questions, US and UK | 400 clicks at $5 | $2,000 | Cost per fitting company; +20% budget if under $150 |
| Reach the committee | Tier 1–2 company list × 5 job functions | 48,000 impressions at $50 CPM | $2,400 | Engaged accounts; cut ad sets with no account lift by week 6 | |
| Programmatic ABM | Stay known | Tier 3 list, 600 matched accounts | 78,000 impressions at $25 CPM | $1,950 | Accounts reached at 1–5 a week; pause if under 1 |
| Retargeting | Bring visitors back | Site visitors, 30 days | Capped at 6 a week | $600 | Return visits from target accounts |

Brand and demand in one plan
Binet and Field's B2B work for the B2B Institute found the best long-term growth at about 46% of budget on brand building and 54% on activation. In practice: broad reach to the whole account list at a steady frequency, and sharper activation on in-market signals. AI ads sit firmly on the activation side; LinkedIn and programmatic usually carry both.
Write the pacing rules in
- Know each platform's daily rules. Google Ads can spend up to twice the average daily budget on a day and up to 30.4 times it in a month; ChatGPT ads average daily budgets over a seven-day week.
- Agree an acceptable range, usually 90–110% of planned spend to date.
- Check pacing daily in week one, then twice a week. The pacing calculator gives the daily budget to land on target.
Decision rules beat dashboards
Every line gets one KPI and one rule, agreed before launch: what earns more money, what gets cut, and when you look. Without rules, every weekly report becomes a debate. With them, week 4 is a five-minute meeting.
| Checkpoint | Question |
|---|---|
| Week 2 | Is everything delivering and tracked end to end? |
| Week 4 | Which lines beat their KPI? Move 10–20% of budget. |
| Week 8 | Which accounts engaged? Re-tier the list. |
| Week 13 | Pipeline and cost per engaged account by line; plan next quarter. |
Questions
How detailed should a B2B media plan be?
One page per quarter, with one row per channel line. Detail lives in platform settings; the plan holds the decisions and the reasons.
How much should go to brand vs demand?
Research by Les Binet and Peter Field for the B2B Institute found B2B growth works best at about 46% brand building and 54% activation. Treat it as a starting point and adjust to your cycle length.
When should I change the plan?
At pre-agreed checkpoints, usually weeks 4 and 8 of a quarter, using the decision rules in the plan. Not every time a weekly number moves.
What should the plan say about AI ads?
Give them a clear job, usually catching in-market buyers on decision questions, and a KPI tied to accounts, not clicks.
