The Google Ads Conversion Ladder: How to Get Closer to Revenue and Profitability

When setting up conversion tracking in Google Ads, there is one principle that matters above almost everything else:

Your conversion tracking should get as close to real revenue as possible.

The more accurately Google understands the actual financial outcomes of your campaigns, the better it can optimise bidding towards profitable customers instead of simply generating leads or clicks.

That is why Google continually pushes advertisers towards value-based bidding strategies such as Target ROAS (Return on Ad Spend). Ultimately, Google wants advertisers feeding real business data into the platform so its machine learning can make smarter decisions.

However, for many lead generation and service-based businesses, this is much easier said than done.

Unlike eCommerce stores with instant transactions, lead generation businesses often have long sales cycles, variable job values, and offline conversions that happen days or weeks later.

So how do you bridge that gap?

The answer is something called the Conversion Ladder.

This framework helps advertisers understand how to progressively improve their conversion tracking and bidding strategy over time.

What Is the Google Ads Conversion Ladder?

The Conversion Ladder represents the journey from basic conversion tracking to advanced profitability-based bidding.

Each rung on the ladder brings your Google Ads account closer to real business outcomes.

At the very top sits the ideal scenario:

Profit-Based Bidding (POAS)

The ultimate goal is not just bidding towards revenue, but towards profitability.

This is often referred to as:

• POAS (Profit on Ad Spend)
• Profit-based bidding
• Margin-based optimisation

Instead of optimising towards revenue alone, Google optimises towards the actual profit generated by each conversion.

For example:

• A £10,000 job with low margins may be less valuable than
• A £5,000 job with very high margins

Profitability-based bidding helps Google prioritise the most commercially valuable customers for your business.

However, most businesses cannot start here immediately.

You need to climb the ladder step by step.

The Starting Point: Forms and Phone Calls

Most lead generation campaigns begin in the middle of the ladder with two primary conversion actions:

• Form submissions
• Phone calls

These are the core actions that demonstrate genuine customer intent.

For service businesses, these are usually the foundation of Google Ads conversion tracking.

Examples include:

• Website enquiry forms
• Quote request forms
• Contact forms
• Calls from the website
• Calls from Google Ads call assets

At this stage, advertisers are usually running:

• Manual CPC
• Maximise Conversions
• Target CPA bidding

Google is primarily optimising towards lead volume rather than revenue quality.

---

When You Don’t Have Enough Conversion Data

One of the biggest issues smaller advertisers face is a lack of conversion volume.

Google’s automated bidding systems need sufficient data to learn effectively.

If your account is not generating enough:

• Form submissions
• Qualified phone calls
• Lead volume

…then it becomes difficult for Google to optimise accurately.

In these cases, advertisers often need to move down the ladder temporarily.

That may sound counterproductive, but it can actually improve campaign performance.

---

Using Micro Conversions to Feed Google More Data

Micro conversions are smaller user actions that indicate buying intent but are not full leads.

Examples include:

• Click-to-call actions
• Click-to-email actions
• WhatsApp clicks
• Live chat interactions
• Message button clicks

These actions do not necessarily mean the user became a lead.

However, they still provide valuable behavioural signals to Google.

For example:

Someone who clicks a phone number is far more likely to become a customer than someone who simply visits the page and leaves.

By adding these micro conversions into your account, you give Google significantly more data to work with.

This can help improve:

• Audience targeting
• Smart bidding performance
• Campaign scalability
• Conversion prediction accuracy

---

Why More Conversion Data Improves Performance

When Google receives more conversion signals, its machine learning systems become more effective at identifying users likely to convert.

This often leads to:

• Lower CPA
• Better lead quality
• Improved scalability
• Increased conversion volume

As campaigns scale, advertisers may eventually generate enough real lead data to remove some of the micro conversions and focus again on core conversions only.

At that point, the account begins moving further up the ladder.

---

The Next Step: Assigning Conversion Values

Once your campaigns are producing steady lead volume, the next stage is introducing conversion values.

Instead of treating every lead equally, you begin assigning estimated monetary values to conversions.

This allows Google to optimise towards:

• Lead quality
• Estimated revenue
• Return on ad spend

Rather than simply optimising for the cheapest leads possible.

---

How to Calculate Lead Values Properly

One common mistake advertisers make is assigning the full sale value to every lead.

That is inaccurate because not every lead becomes a customer.

Instead, you need to calculate an average lead value based on your close rate.

Example

Imagine:

• Your average sale value is £500
• You close 1 in every 5 leads

Your average lead value would be:

£500 ÷ 5 = £100

Therefore:

• Each lead should be assigned a £100 conversion value
• Not £500

This gives Google a much more realistic understanding of the actual value of your leads.

---

Moving Towards Target ROAS Bidding

Once conversion values are in place, you can begin testing value-based bidding strategies such as:

• Maximise Conversion Value
• Target ROAS

At this stage, Google is no longer just optimising for lead volume.

Instead, it is attempting to maximise the total value generated from your campaigns.

This is a major step forward in campaign sophistication.

However, there is still a limitation:

Google still assumes all leads with the same assigned value are equal.

Real businesses are rarely that simple.

---

The Importance of Accurate Conversion Values

The next rung on the ladder involves feeding Google actual sales values from your CRM system.

This is where true value-based bidding begins.

Instead of assigning fixed lead values manually, you send real transaction values back into Google Ads.

For example:

• One lead may generate £10,000
• Another may generate £2,500
• Another may generate only £200

Google can then analyse patterns associated with high-value customers and optimise accordingly.

This dramatically improves bidding accuracy.

---

CRM Integration and Offline Conversion Tracking

To achieve accurate value tracking, businesses typically need:

• A CRM system
• Offline conversion tracking
• Google Ads integration

Popular CRM systems that support this include:

• HubSpot
• GoHighLevel
• Zoho CRM
• Salesforce
• Pipedrive

With proper integration, sales values can be pushed directly back into Google Ads automatically.

This enables Google to optimise towards genuine revenue outcomes rather than estimated values.

---

Reaching the Top: Profitability-Based Bidding

The final stage of the ladder is profitability optimisation.

At this point, you are no longer sending revenue figures into Google Ads.

Instead, you send profit data.

This means Google can optimise towards:

• Highest-margin jobs
• Most profitable services
• Best customer types
• Strongest commercial outcomes

This is the closest possible alignment between Google Ads and actual business performance.

For large businesses with:

• High lead volume
• Strong CRM infrastructure
• Advanced tracking systems
• Sales teams
• Development resources

…it is possible to move directly towards this model.

However, many businesses will never realistically reach this stage.

And that is completely fine.

---

Not Every Business Needs to Reach the Top

One of the most important lessons from the Conversion Ladder is this:

The goal is not necessarily to reach the top.

The goal is to find the level that works best for your business.

Some businesses thrive using:

• Target CPA
• Form submissions
• Phone calls
• Micro conversions

Others succeed with advanced value-based bidding.

There is no universal “correct” rung on the ladder.

In fact, some advertisers move up too quickly and damage performance.

This often happens when:

• There is insufficient conversion data
• Conversion values are inaccurate
• ROAS targets are unrealistic
• Tracking systems are incomplete

When this happens, businesses sometimes need to move back down the ladder to restore profitability.

That is perfectly normal.

---

Enhanced Conversions Can Help You Climb Higher

One feature that can improve conversion measurement significantly is Enhanced Conversions.

Enhanced Conversions help Google recover conversion data that might otherwise be lost due to:

• Cookie limitations
• Browser privacy settings
• Cross-device behaviour

By securely using first-party customer data, Enhanced Conversions improve tracking accuracy and provide Google with more reliable conversion signals.

This can help advertisers generate better optimisation data and potentially move further up the ladder over time.

Final Thoughts

The Google Ads Conversion Ladder is ultimately about improving the quality of the data you give to Google.

The closer your conversion tracking gets to real business outcomes, the more effectively Google can optimise your campaigns.

However, not every business needs:

• Target ROAS
• Profitability bidding
• Advanced CRM integrations

Some businesses perform extremely well using simple CPA-based lead generation campaigns.

The key is understanding:

• Where your business currently sits
• Whether your data supports moving higher
• Which bidding strategy is actually most profitable

Climbing the ladder too aggressively can hurt performance just as much as staying too low.

The smartest advertisers focus on finding the rung that delivers sustainable profitability — not simply chasing the most advanced bidding strategy available.
