What is Content Grouping in Google Analytics?

Scrolling through your Google Analytics “Pages and screens” report often feels like wading through an endless stream of individual URLs. You see traffic for /blog/post-a/, /blog/post-b/, and a hundred other variations, making it nearly impossible to answer a deceptively simple question: "Is my blog working?" To do that, you need a way to group all those individual pages together. This is exactly what Content Grouping is designed to solve, transforming your messy page reports into clean, high-level insights. This tutorial will walk you through exactly what Content Grouping is, why you need it, and how to set it up step-by-step in Google Analytics 4.

What is Content Grouping in GA4?

Content Grouping is a Google Analytics feature that allows you to organize your website’s pages into logical, meaningful categories based on your own custom rules. Instead of analyzing hundreds of separate URLs, you can analyze the performance of entire sections of your website at a glance.

Think of it like creating folders for your website's content right inside your analytics reports. For an e-commerce store, raw reports might look like this:

• /products/womens-running-shoe-xyz
• /products/mens-hiking-boot-abc
• /products/womens-running-shoe-123
• /products/kids-sneaker-asdf

This is too granular to be useful for strategic decisions. With Content Grouping, you could organize this long list into clear, high-level categories that actually mean something to your business:

• Women's Shoes
• Men's Shoes
• Kids' Shoes

Suddenly, you can compare the overall performance of "Women's Shoes" against "Men's Shoes" to understand which larger categories are driving traffic, engagement, and conversions.

Why Should You Use Content Grouping?

Organizing your content is more than just a nice-to-have, it unlocks a much deeper level of analysis that isn’t possible with default page reports. Here are the core benefits:

• Big-Picture Performance Analysis: Immediately see which sections of your site are most popular. You can finally answer questions like, "Does our Blog Content or our Services Pages generate more qualified leads?" or "Are customers more engaged with our 'Tops' or 'Bottoms' clothing categories?"
• Cleaner, More Actionable Reports: Say goodbye to overwhelming lists of URLs. Content grouping aggregates your data into a dozen or so meaningful lines instead of a thousand noisy ones, making reports easier to read and interpret.
• Compare Apples to Apples: You can directly compare different content strategies. For instance, you could group user-generated content (like reviews), expert interviews, and case studies to see which format drives the most registrations or revenue.
• Smarter Decision-Making: When you know which content types are delivering the best results, you know where to invest your time, budget, and resources. If you find that the "Case Studies" group has the highest conversion rate, you have a data-backed reason to produce more of them.

How to Set Up Content Grouping in Google Analytics 4

If you're coming from Universal Analytics, you’ll notice a big difference here. In the old version, Content Grouping was a dedicated feature in the Admin settings. In GA4, things are more flexible but require a few more steps. You’ll need to send the group information as a custom event parameter and then register that parameter as a custom dimension.

The parameter GA4 recognizes by default is neatly named content_group. While there are a few ways to send this parameter, the most common and powerful method is using Google Tag Manager (GTM).

Method 1: The Google Tag Manager (GTM) Method (Recommended)

This is the best method for most users because it doesn't require hard-coding anything on your website and offers incredible flexibility. Just follow these three steps.

Step 1: Create a "RegEx Table" Variable in GTM

First, we need to create a variable that will tell GTM which content group a page belongs to based on its URL. The "RegEx Table" variable sounds technical, but it’s essentially just a powerful find-and-replace tool.

1. In your GTM container, navigate to Variables and in the User-Defined Variables section, click New.
2. Give your variable a clear name, like “GA4 - Content Group.”
3. Click Variable Configuration and choose the variable type RegEx Table.
4. In the Input Variable field, select {{Page Path}}. This tells GTM to look at the part of the URL that comes after your domain name (e.g., /blog/some-article/).
5. Now, we set up the "lookup table" that does the actual grouping. Click + Add Row. In the Pattern column, you’ll enter a regular expression to identify a page type. In the Output column, you’ll enter the name of the content group you want.

Here’s a practical example for a typical company website:

A Quick Breakdown of the Regex:

• ^ means the pattern starts at the beginning of the text.
• /blog/ is the literal text we're looking for.
• .* is a wildcard that means "any character, zero or more times." So, ^/blog/.* matches anything that starts with "/blog/".
• $ means the end of the text. This is useful for exact pages like "/contact-us".
• The final .* pattern on its own is a "catch-all" that will match any URL that didn't match the rules above it, which we group into "Other Pages."

Finally, under Advanced Settings, uncheck "Full Matches Only" and check "Enable Capture Groups and Replace Functionality."

Click Save.

Step 2: Add the Parameter to Your GA4 Configuration Tag

Now that we have our grouping logic in a variable, we need to send it to Google Analytics.

1. In GTM, navigate to Tags and find your main GA4 configuration tag (it's usually called something like "GA4 Config - [Your Measurement ID]"). Click on it to edit.
2. Under Tag Configuration, head to the Fields to Set section (or Configuration Parameters for some setups). Click + Add Row.
3. In the Field Name input, type exactly: content_group. It’s important to use this exact name.
4. In the Value input, click the lego brick icon and select the variable you just created ("GA4 - Content Group").
5. Save your tag.

Step 3: Register the content_group Parameter as a Custom Dimension in GA4

This is the final, crucial step. Even though we’re sending the data, GA4 won't know what to do with it until you officially register it as a dimension you can use in your reports.

1. Go to your Google Analytics 4 property.
2. Click on Admin (the gear icon in the bottom-left).
3. In the Property column, under Data streams, click on your data stream.
4. Scroll down to Configure tag settings and select Custom definitions.
5. On the Custom dimensions tab, click the blue Create custom dimension button.
6. Fill out the fields exactly like this:
7. Click Save.

That's it! Don’t forget to Submit and publish your changes in Google Tag Manager. Keep in mind that it can take up to 24-48 hours for the data to begin appearing in your GA4 reports.

Finding and Using Your Content Groups in GA4 Reports

Once your data starts collecting, you can find your shiny new Content Groups in your page reports.

1. In GA4, go to Reports > Engagement > Pages and screens.
2. By default, you’ll see the standard table with the primary dimension set to “Page path and screen class.”
3. To see your content groups, click the small blue + icon next to the primary dimension dropdown.
4. In the search box that appears, start typing "Content Group" and select it from the list under CUSTOM.

Voila! The report will now be broken down by your custom Content Groups, showing you a beautiful, top-level view of your website's performance by section. You can see Views, Users, Engagement Rate, and Conversions for each group, helping you spot trends and make smarter content decisions instantly.

Final Thoughts

Setting up Content Grouping in Google Analytics 4 is one of the most effective ways to turn a chaotic list of URLs into clean, strategic business insights. By organizing your pages into logical categories, you can finally get a clear, high-level picture of which types of content are truly resonating with your audience and driving your business goals.

While setting up custom dimensions in GA4 is incredibly powerful for ongoing analysis, we know that configuring tools like Google Tag Manager can be time-consuming, especially when you have immediate questions you need to answer. At Graphed, we connect directly to your Google Analytics (along with Shopify, your CRM, ad platforms, and more) to eliminate that initial friction. Instead of manually creating these reporting structures, you can simply ask questions in plain English, like, "Compare engagement for my blog pages versus my services pages last quarter" and get an instant report - no setup required. It lets you explore your data and get answers in seconds, not hours.
