What is Content Drilldown in Google Analytics?

The "All Pages" report in Google Analytics is great for seeing a flat list of your best-performing content, but it doesn't tell you much about your site's structure. That's where the Content Drilldown report comes in, grouping your pages and showing you how entire sections or categories of your website are performing. This article will show you exactly how to find and use this powerful report in both Universal Analytics and GA4 to get a clearer picture of your content strategy.

What is the Content Drilldown Report?

Think about how files are organized on your computer. You don't have every single document saved on your desktop, you group them into folders and subfolders, like Documents > Marketing > Blog Posts. The Content Drilldown report in Google Analytics works the same way, but for your website's pages. It organizes your content based on your URL structure, also known as the page path or directory.

For example, if you have a blog with URLs like:

• www.yoursite.com/blog/google-analytics-tips
• www.yoursite.com/blog/seo-best-practices
• www.yoursite.com/store/product-a
• www.yoursite.com/store/product-b

The standard "All Pages" report shows you these four pages in a list, likely ranked by pageviews. In contrast, the Content Drilldown report would first show you two top-level directories: /blog/ and /store/.

You can see the total traffic for all /blog/ pages combined, and a separate total for all /store/ pages. From there, you can click on /blog/ to "drill down" and see a list of all the individual pages within that directory. This hierarchical view is fantastic for high-level analysis, allowing you to quickly spot which sections of your site are most popular.

Finding the Content Drilldown Report in Google Analytics

Finding this report depends entirely on which version of Google Analytics you're using. The classic version, Universal Analytics (UA), has a dedicated report, while in Google Analytics 4, you need to take a couple of extra steps to get similar insights.

For Universal Analytics (UA)

If you're looking at historical data in an older UA property, finding the report is straightforward:

1. Navigate to your Universal Analytics property.
2. From the left-hand menu, go to Behavior > Site Content > Content Drilldown.

That's it. You'll land on a report showing your website's top-level page paths (directories). You can click on any of them to see the subdirectories or pages within that path.

For Google Analytics 4

Google Analytics 4 rebuilt its reporting interface from the ground up, and you won't find a direct, one-to-one "Content Drilldown" report. However, you can easily replicate its functionality using filters within the standard Pages and Screens report.

Here’s how to do it:

1. Go to your GA4 property and navigate to Reports > Engagement > Pages and screens.
2. By default, this report shows you all your pages, similar to the "All Pages" report in UA.
3. Above the data table, you'll see a search box that says "Search." Click it.
4. The primary dimension should be "Page path and screen class." Make sure that's selected.
5. In the search box next to it, type the directory you want to analyze. For example, to see all your blog pages, you might type /blog/ and hit enter.

This filters the list to show you only the pages that live within that directory, effectively achieving the "drilldown" effect. While it requires an extra step, it allows you to analyze your content categories just as you would in the UA report.

How to Use the Content Drilldown Report: 5 Actionable Use Cases

Simply finding the report is only half the battle. Its real value comes from the insights you can pull to inform your content and marketing strategy. Here are five practical ways to use it.

1. Identify Your Top Performing Content Categories

The most immediate benefit is seeing which sections of your website resonate most with your audience. When you first open the report, you might see something like this:

• /blog/ - 150,000 pageviews
• /services/ - 40,000 pageviews
• /case-studies/ - 15,000 pageviews
• /about/ - 5,000 pageviews

Right away, you can tell that your blog is your biggest traffic driver. This kind of high-level insight helps you decide where to invest your resources. If the blog is driving traffic, maybe it's time to create more content. If your services pages are lagging, perhaps they need more internal links from the popular blog posts to guide users there.

2. Analyze and Compare Product Sub-categories

For e-commerce sites, this report is a goldmine. Imagine you have a URL structure like /products/mens/shoes/ and /products/womens/shoes/. The Content Drilldown lets you compare broad categories (/mens/ vs. /womens/) and then drill down further to see how shoes perform within each parent category.

If you discover that the /products/mens/ directory has a much lower average time on page and a higher exit rate than the /products/womens/ directory, that's a signal to investigate. Is there an issue with the product listings, photography, or navigation on the men's side?

3. Find Underperforming Content That Needs an Update

Every website has old content gathering digital dust. The drilldown report is an efficient way to find it. Drill into a major category like /blog/ and then sort the individual pages by Pageviews in ascending order. The pages at the bottom are your least popular.

These underperformers aren't necessarily failures - they might be excellent candidates for a content refresh. Could you update the information, improve the SEO, add new media, or merge it with another similar article? Often, giving an old post a refresh is much faster than writing a new one from scratch.

4. Spot Potential Navigation or User Experience (UX) Issues

The metrics in the drilldown report can illuminate how users interact with your site's structure. Pay close attention to the % Exit column for your parent directories (/blog/, /services/, etc.).

If a main category page itself has a very high exit rate, it could mean visitors aren't finding a clear next step. They land on your main /services/ page, get confused or overwhelmed, and leave without clicking through to an individual service. This could indicate you need clearer calls-to-action (CTAs), better internal links, or a simpler page design.

5. Diagnose URL and Site Structure Problems

Sometimes, this report uncovers things that shouldn't be there at all. For example, you might see entries like:

• A page path full of meaningless query parameters (e.g., /?id=12345&source=email).
• An entry for (not set), which can point to issues in your tracking code implementation.
• URLs from a staging or test version of your website that are accidentally being tracked in your live property.

Cleaning up your URL structure not only makes your analytics report more useful but is generally good practice for SEO and user experience.

A Quick Note on URL Structure

The Content Drilldown report is incredibly useful, but it has one major prerequisite: an organized URL structure. It relies entirely on readable, hierarchical URLs to group your content. If your URLs are built on query parameters (e.g., yoursite.com/default.aspx?pageid=42), the report will be less useful because it won't be able to identify clear directories.

For this reason, using clear, semantic URLs (like yoursite.com/blog/topic-name) is best practice not only for SEO but also for making your analytics data much easier to interpret.

Final Thoughts

The Content Drilldown report provides a bird's-eye view of your site's performance that you can't get from a simple list of pages. By grouping your content by directory, it helps you quickly understand which content categories are an attraction and which ones might be in need of attention, giving you foundational insights to guide your marketing efforts.

Of course, manually filtering reports in Google Analytics week after week can become a chore, especially when you need to combine insights with data from your ad platforms, CRM, or e-commerce store. That’s why we built Graphed. We wanted to make getting cross-platform insights as simple as asking a question. For instance, you could simply ask, “Show me how many leads my latest blog post generated from Facebook ads this week” and instantly see the data, pulling everything together without leaving the dashboard.
