How to Conditionally Display Content in WordPress Based on URL Rules (The Easy Way)

Have you ever needed to display a specific banner only when a user clicks an ad campaign link? Or perhaps you wanted to inject a tracking pixel exclusively on a “Thank You” page that contains a unique URL query parameter?

Historically, doing this in WordPress required writing custom PHP logic in your functions.php file or relying on clunky page builders. But what if you could manage this with a clean, centralized rule engine?

I’m excited to introduce Custom Link Display, a powerful and lightweight WordPress plugin we’ve built entirely to solve this exact problem. In this guide, I’ll show you how to use it to inject conditional content like a pro.

The Problem: Dynamic Content for Dynamic Users

Standard WordPress pages are static in their layout. If you need to output HTML based on how the user arrived (e.g., yoursite.com/checkout?campaign=blackfriday), you usually hit a wall.

Common use cases include:

• Marketing & SEO: Showing a special discount code banner only to users from a specific ad campaign.
• Tracking: Firing a JavaScript conversion pixel only on very specific, nested, or query-generated URLs.
• UX Localization: Giving localized welcome messages if the URL path matches a region keyword (e.g., /uk/ vs /us/).
• Affiliate Links: Dynamically replacing standard links with affiliate links depending on dynamic URL strings via shortcodes.

The Solution: Custom Link Display Plugin

Custom Link Display steps in to give you absolute control over what gets displayed and exactly where and when it gets displayed.

Instead of writing code, you get a beautiful, native WordPress dashboard to set up conditional visibility rules.

Core Features

• 🎯 Smart Target Matching: Match URLs by an Exact string, use “Contains” to catch query parameters (like ?source=newsletter), or use full Perl-Compatible Regular Expressions (Regex) for ultimate precision.
• 🛠️ Mutually Exclusive Content Modes:
  • Custom HTML: A raw sandbox for you to paste <script>, <style>, <div>, or pixel tags perfectly tailored to the condition.
  • Visual Link Configurator: A no-code visual builder that instantly constructs clean, SEO-friendly HTML anchor links. Perfect for updating call-to-actions dynamically.
• 📍 Flexible Placements: Automatically inject your rules straight into the Header, Footer, Before Content, or After Content.
• 🧩 Shortcode Flexibility: Put your rule on ‘Shortcode Only’ placement, copy the generated  tag, and drop it anywhere in Elementor, Divi, or the Gutenberg block editor. The shortcode will evaluate the URL and only render if it’s a match!
• ⏳ Auto-Expiry: Running a weekend promotion? Set an expiry date on your rule, and it will automatically stop displaying when the timeline ends.

How to Set Up Your First Conditional Rule

Getting started is blazing fast.

1. Install and Activate: Download the plugin and upload it to your WordPress dashboard via Plugins > Add New.
2. Access the Dashboard: Click the new URL Content menu item on your admin sidebar.
3. Create the Rule: Click the Add New Rule button.
4. Configure the Match: Under Target URL / Path, enter your conditional string (e.g., ?promo=20). Change the Match Type to Contains.
5. Decide Placement: Select where you want this to show up. For a global banner, Before Content is a great default.
6. Add the Content: Click the pencil icon to toggle the content editor. Here, select Custom HTML and paste your banner code or tracking pixel.
7. Save: Hit Save All Rules and you’re done!

That’s it. Next time a user visits a URL containing ?promo=20, your HTML will inject instantly. The next user who visits the identical page without the query string will see nothing.

Conclusion

Customizing your visitor’s experience based on how they browse your website shouldn’t require hiring a developer. Whether you’re tracking complex funnels, managing dynamic affiliate links, or crafting personalized user experiences, Custom Link Display brings enterprise-level routing logic directly to your WordPress dashboard.
