If you want better content analysis in Google Analytics 4, tracking just URLs is not enough. A list of individual web pages can tell you what got traffic, but it does not make it easy to understand which kinds of content are actually driving your website forward.

That is where page type tracking can help. Instead of only measuring individual URLs, you can classify each web page by format and send that value into GA4 as a custom parameter. This makes it possible to analyze performance by content type, such as case studies, book summaries, calculators, site search, the home page, and anything that does not yet fit into a defined bucket.

In my case, I used Google Tag Manager to identify page types based on URL patterns and page titles, then passed that value to GA4 using a custom parameter called page_type.

What page type tracking does

Page type tracking adds a structural content layer to your analytics. Instead of only seeing that a specific web page got traffic, you can now understand whether that traffic came from a case study, a calculator, a book summary, a home page visit, or some other kind of content.

Examples of page type values might include:

home-page
case-study
book-summary
calculator
site-search
404
not-classified

Once the custom dimension had been collecting data for a few months, I could finally analyze traffic by page type instead of individual URLs. Here’s what that report looks like on my own site.

Why page type tracking is useful in GA4

Once page type is available as a custom dimension, GA4 becomes much more useful for content analysis.

You can answer questions like:

1. Which page types attract the most sessions?
2. Which page types drive the strongest engagement?
3. Which page types are most likely to bring in organic traffic?
4. How much of my website still falls into a general not-classified bucket?

This becomes even more powerful when combined with topic tracking, because you can analyze both the format of the web page and the subject of the content.

Before you start

This walkthrough presumes:

1. You are using Google Tag Manager.

2. Your GA4 page_view event is firing through GTM.

3. Your website has consistent URL patterns or titles that can be used to identify different page types.

4. You want page types to be stable over time and mutually exclusive.

Why page type rules need to be precise

A page type should describe the format of the content, not the topic. For example, case study is a page type. Martech is a topic. Those are different things and should be tracked separately.

The goal is to give each web page one clear page type value. That keeps the classification stable and makes reporting easier to trust.

It is also important not to create too many page types too quickly. A small, meaningful set is usually better than trying to classify every edge case on day one.

Step 1: Define your page type values

Start by deciding which page types your website actually needs. In my setup, I used these values:

home-page
case-study
book-summary
calculator
site-search
404
not-classified

The first several values represent meaningful content structures. The final value, not-classified, acts as an intentional catch-all bucket.

Why not-classified matters

If no matching rule is found, the script returns not-classified.

This is not a mistake. It is a useful fallback. It gives you a deliberate “other” bucket so that uncategorized web pages do not get confused with GA4 system labels like not set. Over time, monitoring the percentage of sessions tied to not-classified can help you decide whether more page types are needed or whether the current taxonomy is already healthy.

Step 2: Create a Custom JavaScript Variable in Google Tag Manager

In GTM, create a new User-Defined Variable using the Custom JavaScript variable type.

Name it something like:

Page Type

Then use logic that checks the current URL path and page title to determine the correct page type.

Here is an example:

function() {

var path = window.location.pathname.toLowerCase();
var url = window.location.href.toLowerCase();
var title = document.title.toLowerCase();

if (
  title.includes("marketing with dave - all things digital marketing") ||
  title.includes("marketing with dave | all things digital marketing")
) {
  return "home-page";
}

if (title.includes("404")) {
  return "404";
}

if (url.includes("/search/?q=")) {
  return "site-search";
}

if (path.includes("case-study")) {
  return "case-study";
}

if (path.includes("book-summary")) {
  return "book-summary";
}

if (path.includes("the-a-to-z")) {
  return "the-a-to-z";
}

if (path.includes("the-evolution-of")) {
  return "the-evolution-of";
}

if (
  path.includes("calculator") ||
  path.includes("analyzer") ||
  path.includes("tools")
) {
  return "calculator";
}

return "not-classified";

}

How the script works

This script checks a small set of rules in order.

1. It looks for the home page title.

2. It checks for a 404 title.

3. It checks for a site search URL pattern.

4. It checks for specific URL structures like case-study, book-summary, the-a-to-z, and the-evolution-of.

5. It checks for calculator-related words in the URL.

6. If no match is found, it returns not-classified.

The order matters. More specific rules should always come before the fallback bucket.

Step 3: Add page_type to your GA4 page_view tag

Once the variable is created, open the GA4 page_view tag in Google Tag Manager.

If you have both a standard page_view tag and an internal version, update both so the data stays consistent.

In Event Parameters, add:

page_type = {{Page Type}}

This tells GTM to send the resolved page type value with each page_view event.

Step 4: Preview your changes in GTM

Before publishing, use Preview mode in GTM.

Visit several web pages on your website and verify that the variable returns the right values.

Examples:

A case study URL should return case-study.

A book summary URL should return book-summary.

A calculator or analyzer web page should return calculator.

The website home page should return home-page.

A regular article that does not match any defined rule should return not-classified.

Step 5: Publish the GTM container

Once Preview mode confirms the values are correct, publish the GTM container.

At that point, GTM is sending the page_type parameter to GA4, but GA4 still needs one final setup step before you can use it in reporting.

Step 6: Register the custom dimension in GA4

In GA4, go to Admin, then Custom definitions.

Create a new custom dimension with these settings:

Dimension name: Page Type

Scope: Event

Event parameter: page_type

Save the dimension.

From that point forward, GA4 will store and report on the page_type parameter.

Important note about historical data

GA4 custom dimensions are not retroactive.

This means page type data will only be available for traffic collected after the GTM changes are published and the custom dimension is created.

If you want a historical view, you would need to recreate it manually using existing URLs in a spreadsheet or another reporting layer.

How to analyze page type in GA4

Once the data starts flowing, one of the simplest and most useful reports is an Exploration showing sessions by page type.

A basic starting point is:

Rows: Page Type

Values: Sessions

This quickly shows what percentage of traffic is going to case studies, calculators, book summaries, site search, and everything else.

You can also combine page type with content topic to build a matrix like:

Rows: Content Topic

Columns: Page Type

Values: Sessions

That helps you understand both what the content is about and what format it takes.

Why this works well for content-driven websites

If your website includes multiple recurring content formats, page type tracking gives you a much better structural view of performance.

Instead of relying only on individual URLs, you can now see how the website performs by content model.

That is useful for editorial planning, content investment decisions, and identifying which kinds of web pages are becoming your strongest entry points.

Final takeaway

Page type tracking is one of the most useful content upgrades you can make in GA4. It adds a structural layer that makes your reporting far more meaningful than a simple list of URLs.

If your website already has recognizable URL patterns or stable page titles, Google Tag Manager can classify those web pages automatically and send the values into GA4 with very little maintenance required later.

And by keeping not-classified as an intentional fallback, you retain visibility into the portion of your website that still sits outside your current content taxonomy.

Reading Time: 5 minutes

If you run a content-heavy WordPress website, there is a good chance you care about more than just web page views. You may also want to know which content topics actually drive sessions, engagement, and returning visitors.

That is where category tracking can help. In my case, I wanted Google Analytics 4 to capture the WordPress Category assigned to each article so I could analyze traffic by topic. This is especially useful when your content spans areas like analytics, martech, paid advertising, SEO, content marketing, and more.

The important detail is that WordPress Categories and WordPress Tags are different. If your website uses Categories as the main topic label on articles, your Google Tag Manager setup needs to pull from the Category link, not from a Tag link.

What this setup does

This approach reads the article’s visible WordPress Category from the web page, normalizes it into a GA4-friendly value, and sends it with your page_view event as a custom parameter.

For example:

Martech becomes martech

Paid Advertising becomes paid-advertising

Search Engine Optimization (SEO) becomes search-engine-optimization-seo

Artificial Intelligence (AI) becomes artificial-intelligence-ai

Why use Category tracking in GA4?

Once this is set up, you can analyze website performance by topic instead of just by URL.

This lets you answer questions like:

Which categories attract the most sessions?

Which categories drive the longest engagement time?

Which categories perform best for case studies, calculators, or other content types?

If you already have page type tracking in place, category tracking becomes even more powerful because you can compare format and topic together.

Before you start

This walkthrough presumes:

1. You are using WordPress.

2. Your article category appears visibly on the web page as a link.

3. The category link uses a URL structure containing /category/.

4. You already have Google Tag Manager installed.

5. Your GA4 page_view tag is firing through GTM.

Step 1: Confirm that your website uses Categories, not Tags

This part matters more than people realize.

If your website displays the topic label under the title and that label links to a URL like /category/martech/, then your GTM script should look for Categories.

If your setup uses WordPress Tags instead, the link would usually contain /tag/.

Step 2: Create a Custom JavaScript Variable in Google Tag Manager

In Google Tag Manager, go to Variables and create a new User-Defined Variable.

Choose Custom JavaScript as the variable type.

Name it something like:

Content Topic

Then use this script:

Some tutorials detect categories using URL patterns like /category/. That works on some WordPress websites, but many themes remove the category base from URLs. A more reliable approach is to target the category element directly in the HTML.

function() {
  var category = document.querySelector('.ast-terms-link a');
  if (!category || !category.textContent) return 'not-classified';

  return category.textContent
    .trim()
    .toLowerCase()
    .replace(/[()]/g, '')
    .replace(/\s+/g, '-')
    .replace(/[^a-z0-9-]/g, '')
    .replace(/-+/g, '-')
    .replace(/^-|-$/g, '');
}

Note: The selector .ast-terms-link a works for Astra theme. If you are using a different theme, inspect the category link on the web page and adjust the selector accordingly.

How the script works

This script does five things:

1. It looks for the first link on the web page that contains /category/.

2. It grabs the visible text of that link.

3. It trims extra spaces.

4. It converts the value to lowercase.

5. It removes special characters and replaces spaces with hyphens.

If no category is found, it returns not-classified.

This acts as a deliberate “other” bucket. Instead of mixing uncategorized traffic with GA4 labels like not set, you can clearly see what portion of your content taxonomy is missing or incomplete. Over time, the goal is not to eliminate not-classified, but to keep it at a healthy percentage.

Step 3: Add the parameter to your GA4 page_view tag

Next, open the GA4 page_view tag in Google Tag Manager.

If you have a standard page_view tag and a separate internal version, make sure you update both so the data stays consistent.

In the Event Parameters section, add a new parameter:

content_topic = {{Content Topic}}

That tells GTM to send the normalized category value with every page_view event.

Step 4: Preview the changes in GTM

Before publishing, use Preview mode in Google Tag Manager.

Open a few different article web pages and confirm that the Content Topic variable returns values you expect from your WordPress Categories.

For example, on a Martech article, the variable should return:

martech

On a Paid Advertising article, it should return:

paid-advertising

If you see a value that does not match one of your approved categories, your selector may be pulling from the wrong part of the web page.

Step 5: Publish the GTM container

Once preview mode looks good, publish the container.

At this point, GTM is sending the custom parameter to GA4, but Google Analytics 4 still needs one more step before you can use it in reports.

Step 6: Register the custom dimension in GA4

In GA4, go to Admin, then Custom definitions.

Create a new custom dimension with the following settings:

Dimension name: Content Topic

Scope: Event

Event parameter: content_topic

Save the custom dimension.

From that point forward, GA4 will store and report on the content_topic parameter.

Important note about historical data

GA4 custom dimensions are not retroactive.

That means this setup will only classify data collected after the custom dimension is created and GTM is published.

If you want historical analysis, you will need to build it manually using a spreadsheet or another reporting layer.

How to use the data in GA4

After the data starts flowing, the easiest place to analyze it is in Explorations.

A simple starting report is:

Rows: Content Topic

Columns: Page Type

Values: Sessions

This makes it easy to see which topics are driving traffic and how those topics map to different kinds of content.

Examples might include:

Case studies in martech

Book summaries in leadership

Articles in analytics

Calculators in website-related topics

Why this works well for WordPress websites

The biggest advantage of this setup is that it uses the taxonomy you already maintain in WordPress.

You are not inventing a separate analytics classification system. You are simply exposing your existing editorial structure to GA4.

That makes the reporting much easier to trust.

Can this work outside WordPress?

Yes, but the implementation details change.

The broader concept is the same: identify the topic label on the web page, extract it with GTM, normalize it, and send it to GA4 as a custom parameter.

What changes is the selector. Instead of looking for a WordPress Category link containing /category/, another platform might use a different class name, data attribute, or metadata element.

So the process is portable, but the selector is platform-specific.

Final takeaway

If your WordPress website uses Categories as the primary topic label for articles, GTM should pull from Categories and not Tags. That one detail can be the difference between clean, trustworthy GA4 topic reporting and a messy dataset you cannot rely on.

Once you set this up, GA4 becomes much more useful for understanding what your content is really doing by subject area, not just by individual URL.
