How to link Google Ads to GA4
Let’s dive into the steps to connect your GA4 property with Google Ads:
1. Get editor permission for GA4 and admin access to Google Ads
Before linking your Google Ads account to a GA4 property, ensure you have the necessary ‘editor’ permission for that property.
You’ll also need admin access to the Google Ads account that you’re trying to link.
Note: You are able to link all your GA4 properties to both individual Google Ads accounts and Google Ads Manager accounts. Plus, there’s a generous limit of creating up to 400 links property.
2. Go to Google Analytics admin settings

3. Select Google Ads links
Click the ‘Google ads links‘ from the ‘property‘ column.
4. Select link
Then click on the ‘Link’ option

6. Chose the Google Ads accounts you want to link

Then select the “Next” option.
7. Choose your configuration settings
You will see a screen like the one below:
Next, you’ll see the option to disable the following features: ‘Personalized Advertising’ and ‘Auto-Tagging‘.
When you choose to disable Personalized Advertising and Auto-Tagging when connecting Google Ads to GA4, the following will happen:
What happens when you disable personalised advertising?
When you disable Personalised Advertising, Google cannot collect data about your users’ interests and demographics. This data is used to show your ads to people who are more likely to be interested in them. As a result, you may see a decrease in the impressions and clicks your ads receive.
In order to disable ‘Personalized Advertising’, simply hit the toggle button to ‘OFF’.
What happens when you disable auto-tagging?
When you disable Auto-Tagging, Google will not automatically add tracking codes to your website’s pages when someone clicks on one of your ads. This means you must manually add the tracking code to your pages. If you do not do this, you will not be able to track the performance of your ads in Google Analytics.
In order to disable ‘Auto-Tagging’, first hit the down arrow button:
Then select “Leave my auto-tagging settings as they are” from the dropdown.
We recommend keeping “Personalized Advertising” and “Auto-Tagging” enabled.
Now click the “Next” button.
8. Review your configuration and submit
Now, take a moment to check all the configuration settings we’ve set so far. If everything looks in order, simply hit the “Submit” Button.
You should now be looking at a screen confirming the successful linking of your GA4 property with your chosen Google Ads account(s). You now know how to link Google Ads to Google Analytics

Where to find Google Ads data in GA4
There are a few different ways to find Google Ads data in GA4.
Reports > Acquisition > Acquisition Overview > View Google Ads campaigns card
This card provides a comprehensive overview of your Google Ads campaigns, including metrics such as clicks, cost, cost per click, and return on ad spend. You can also select different Google Ads dimensions, such as ad group name, keyword text, and query.
Reports > Acquisition > User acquisition > Select Google Ads dimensions
This report shows how users find your website through different channels. But unfortunately, you can’t find ad-related metrics here.
Reports > Acquisition > Traffic acquisition
You can then select the “Session campaign” dimension to see which marketing campaigns are driving the newest sessions. However, this would also include other campaigns being tagged with UTMs, and you won’t see any Google Ads-specific metrics here.
Explorations
You can also create explorations reports for Google Ads in GA4. This gives you the flexibility to add whatever metrics are important to you and apply any segments to get more context.
Whichever method you use to find Google Ads data in GA4 depends on your needs.
If you want a comprehensive overview of your Google Ads data, the first one is a good option. If you want to see how users came to your website through Google Ads, then both the second & third options from the list are good picks.
And if you want the flexibility to add whatever metrics are important to you, Explorations is the one you should look into. Once you have found the Google Ads data you are looking for, you can start digging more to make the necessary adjustments for improving your ROI.
Data discrepancies between GA4 and Google Ads
You can encounter some cases where the data from GA4 and Google Ads accounts do not match but that’s pretty normal. There are several common reasons for that, depending on each business account.
Here are some of the common reasons for discrepancies between GA4 and Google Ads:
Google Ads and Google Analytics use different dates of transaction
Google Ads reports conversions against the date/time of the click that led to the conversion. Analytics uses the date/time of the conversion itself. Note that the All conv. (by conv. time) column shows the number of conversions imported from Analytics based on the date of the conversion rather than the date of click.
Attribution models
The discrepancy often lies in each platform’s distinctive attribution models. Google Ads typically utilises the last-non-direct-click model, whereas GA4 uses a data-driven attribution model, accrediting each relevant interaction point. This difference might result in an increased number of conversions on Google Ads.
Note: Google is developing a ‘Conversion Differences’ report within GA4. This report will enable users to compare differences between both tools based on their distinct attribution models.
Different metrics
Google Ads primarily measures clicks and ad impressions, while GA4 is more interested in sessions, engaged sessions, and views. Therefore, multiple clicks on the same ad that lead to the website will be counted individually in Google Ads, while GA4 will consider them as a single session.
UTM tagging
Failing to enable Auto-Tagging or improperly tagging URLs can lead to discrepancies. Data may become distorted and fail to be correctly attributed to your Google Ads campaigns.
Data Sampling
In GA4, large data sets or long-range data may invoke sampling, meaning you won’t have access to all the data for analysis. You can get around this by shortening the time range or exporting the data to BigQuery for comprehensive analysis.
Inaccurate or Missing Tracking
If your tracking setup is erroneous or absent on specific landing pages, it can generate inconsistencies. A common pitfall is when cross-domain tracking malfunctions, causing broken sessions, resulting in more data appearing in Google Ads and incorrect data in GA4.
Different Time Zones
Non-aligned time zones can cause data synchronisation problems. It’s a simple fix, as we can change and set matching time zones across both tools.
Usage of Ad-blockers
Users employing ad-blockers can cause data discrepancies. Ad-blockers could either block both tools entirely or inconsistently, resulting in partial data transmission. This situation can pose a challenge when attempting to compare data.
While certain circumstances may be beyond your control, efforts can be made to address them. However, it’s essential to understand that a certain level of inconsistency will always exist between these two tools. A time-tested approach would be to utilise a cloud-based tool, such as BigQuery from Google Cloud Platform, and join the tables to extract valuable insights.
For your colleagues within the department, crafting user-friendly dashboards can be a powerful way to illustrate the effects of your marketing endeavours. The crux of the matter is that understanding the root causes of discrepancies allows you to make efforts to minimise the differences.
Additional tips for avoiding data discrepancies between GA4 and Google Ads

Make sure you use the same conversion goals in both GA4 and Google Ads. This will help you compare apples to apples when looking at your data.
Use the same attribution model
As mentioned above, GA4 and Google Ads use different attribution models. Using the same attribution model in both cases is vital to compare the data between the two platforms.
Use the same time frame
When comparing GA4 and Google Ads data, it is crucial to use the same time frame. This will help you to ensure that you are comparing apples to apples.
Use the same data sources
Make sure you use the same data sources in both GA4 and Google Ads. This will help you to ensure that you are comparing apples to apples.
