If you have ever opened Google Analytics and Google Ads side by side and wondered why the numbers do not match, you are not alone.
If you have ever opened Google Analytics and Google Ads side by side and wondered why the numbers do not match, you are not alone.
Maybe Google Ads says a campaign generated 24 conversions, while GA4 shows 17. Your CRM has a different number again. Then someone pulls up a dashboard with another version of the story.
So which number is right?
Potentially all of them.
The problem is that these platforms are not necessarily measuring the same thing, in the same way, over the same period of time. Understanding those differences matters because reporting is not just about producing numbers. Those numbers eventually become business decisions.
Google Ads and GA4 are designed for different purposes.
Google Ads is primarily concerned with understanding what happens after someone interacts with your advertising. GA4 is looking at behaviour across your website or app and can assign credit across a broader mix of channels and interactions.
That creates differences in how conversions are attributed and reported.
A customer might:
Google Ads and GA4 may not give the same amount of credit to those interactions.
Neither platform necessarily has bad data. They are answering slightly different questions.
Attribution determines which marketing interactions receive credit when someone converts.
GA4 allows businesses to configure things like the reporting attribution model, the channels eligible to receive credit, and the lookback window used for key events.
Those settings can significantly change what you see in a report.
The lookback window is a good example.
If someone discovers your company through a campaign and converts weeks later, whether that original interaction receives credit depends partly on how your analytics are configured.
For a business where customers typically make a decision within a few days, that may be relatively straightforward.
For a consulting firm, B2B company, professional service, or other business with a longer sales cycle, the customer journey can stretch across weeks or months.
Using analytics settings without considering how your customers actually buy can give you a distorted picture of what is working.
There is another surprisingly common problem.
Businesses often use the word "conversion" as though it refers to one universally defined metric.
It does not.
A conversion could mean:
Those are very different business outcomes.
Your Google Ads account might count one set of actions while GA4 tracks another. Your CRM may only contain people who made it further into the sales process.
That is why comparing the top-line conversion number from three different systems without first understanding what each one includes can create more confusion than clarity.
This is where we see businesses get into trouble.
Analytics gets installed. Events start firing. A dashboard is created. Reports contain plenty of numbers.
That does not necessarily mean the business has a good measurement system.
Before you can rely on your reporting, you need to decide what you are actually trying to measure.
Which actions matter to the business?
Which are leading indicators?
Which represent actual revenue?
How long does your typical customer journey take?
Which systems contain the most reliable information at each stage?
And when two platforms disagree,which one should you use to answer the specific question you are asking?
Without that foundation, adding more dashboards rarely solves the problem. You just end up with more ways to look at data you still do not fully trust.
If your GA4, Google Ads and internal numbers are telling you different stories, start by looking at the setup rather than immediately assuming your marketing performance has changed.
· Review what you are counting as a key event.
Make sure the actions being treated as important actually correspond to meaningful business outcomes.
· Check your attribution settings.
Review the attribution model, eligible channels and lookback windows being used in GA4.
· Compare conversion definitions across platforms.
Confirm that Google Ads, GA4 and your CRM are actually counting comparable actions before comparing their totals.
· Check for duplicate tracking.
If the same action is being measured in multiple ways, make sure you are not accidentally counting it twice.
· Look beyond conversions.
Traffic quality, engagement, lead quality, sales data and revenue can provide important context that a single attribution report cannot.
· Document your measurement strategy.
Your team should know what your primary metrics mean, where they come from and which source should be used for different types of decisions.
Businesses have access to an enormous amount of information now.
The challenge is deciding which information deserves your attention.
A dashboard with 40 metrics is not necessarily more useful than one with eight. A sophisticated attribution model is not useful if the conversion tracking feeding it is wrong. And a perfectly accurate marketing metric can still lead to a bad decision if it is interpreted without the context of the business.
Good analytics should help you understand what is happening, ask better questions and make better decisions.
If your reporting is creating more questions than answers, the solution may not be another dashboard. It may be taking a closer look at what you are measuring in the first place.
At Bishop & Royal, we help organizations turn complex data into useful decision support. That can include analytics and measurement strategy, dashboards and metrics, quantitative analysis, forecasting, and figuring out how different sources of business data fit together.
If your reports do not seem to agree, or you are not confident that your current measurement setup is giving you the information you need, we can help you sort through it.
