Hey B2B marketer! Without clearly defined rules for testing and optimizing your PPC campaigns, you’re either going to pause things prematurely, or you’re going to scale too early.

‍

In this article, you’ll learn how to make decisions based on logic instead of emotions when managing your PPC campaigns.

‍

Let’s dive in! 👇

‍

TABLE OF CONTENTS

1 - Find Your Breakeven Costs

Your goal is to drive more pipeline and revenue, so knowing how much you can afford to spend per lead or click is the first step to ensure you don’t lose money while optimizing for performance.

‍

Breakeven Cost per Lead

‍

Here’s what you will need  to  calculate your  breakeven cost per lead:

‍

  1. Take your average deal size
    ‍
  2. Multiply that towards your lead to close won rate.
    ‍

Example: 
‍

If your deal size is $3,000 and your close rate is 10%, your breakeven cost per lead is $300.
‍

This means that when optimizing your ppc campaigns, you can spend up to $300 to break even. So you’ll start to lose money if anything goes after $300.

Breakeven Cost per Click
‍

This is a step further and will inform what you’re willing to pay the channel for a click. 
‍

Here’s what you will need to calculate your  breakeven cost per click:
‍

  1. Take the breakeven cost per lead target
    ‍
  2. Multiply that towards your landing page or form conversion rate if you use lead gen forms.
    ‍

Example: 
‍

If your breakeven cost per lead is $300 and your landing page/form conversion rate is 5%, your breakeven cost per click is $15.

This foundational math grounds your optimization decisions and eliminates emotional bias, ensuring you stay within profitable bounds.

2 - Apply a Non-Performer Rule

When ads fail to deliver results, emotions often lead us to either pause campaigns too soon or let them run too long.
‍

This is where the non-performer rule saves the day.
‍

The rule is simple: 
‍

  • Pause any ad that spends 2-3x your target cost per lead without generating conversions.
    ‍
  • Timeframe: All time.

‍

Example:
‍

If your target is $300 per lead and you spend $600-$900 without results, it’s time to hit pause.
‍

This removes emotional bias and gives your ads a fair shot before deciding their fate.
‍

By doing this, you stop wasting money and gain clarity on what isn’t working, allowing you to allocate your budget more effectively.

‍

3 - Apply a Maintenance Rule

Even great ads don’t perform forever. Over time, performance may drop due to ad fatigue or other factors.
‍

The maintenance rule will help you handle these scenarios with logic, not guesswork. 
‍

Here’s how it works: 
‍

  • If an ad’s cost per lead increases to 1.5-2x your target over a 7-14-day period, it’s time to pause.
    ‍

Example:
‍

If your cost per lead target is $300, an ad costing $450-$600 per lead is no longer viable, and you should pause it.
