UTM Link Builder with Reusable Templates
Build, save, and reuse UTM campaign links instantly. A mini SaaS prototype powered by vanilla JavaScript.
What Are UTM Parameters?
UTM parameters are tags you add to URLs to track the effectiveness of marketing campaigns in analytics tools like Google Analytics. They help you identify which sources, mediums, and campaigns drive the most traffic and conversions.
The five standard UTM parameters are: utm_source (traffic source), utm_medium (marketing medium), utm_campaign (campaign name), utm_content (ad variation), and utm_term (paid keywords).
Interactive Demo
Try the UTM builder below. Enter your URL and campaign details, then save templates for quick reuse.

Why Templates Speed Up Growth Experiments
Growth marketers run dozens of experiments weekly. Manually building UTM links for each campaign is tedious and error-prone. Reusable templates eliminate repetitive work and ensure consistency across campaigns.
With saved templates, you can instantly generate links for recurring campaigns like newsletters, social posts, or paid ads. This speeds up execution and reduces mistakes in tracking parameters.
How the JavaScript Works
The demo uses vanilla JavaScript with no external libraries. It listens to input changes, validates the base URL format, and builds the final URL by appending UTM parameters using encodeURIComponent() to handle special characters safely.
Templates are stored in localStorage as JSON objects. When you save a template, the app serializes the current form state and stores it with a unique name. Loading a template retrieves the data and populates the form fields instantly.
The copy-to-clipboard feature uses the modern navigator.clipboard.writeText() API with fallback handling. Success and error messages appear as toast notifications with auto-dismiss timers.
Accessibility Considerations
All form inputs have proper labels for screen readers. The copy button is disabled until a valid URL is generated. Toast messages use ARIA live regions to announce status changes to assistive technologies.
How AI Builder Can Generate This in WordPress
AI Builder is a WordPress plugin that generates complete pages from simple descriptions. Instead of manually coding Gutenberg blocks, CSS, and JavaScript, you describe what you need and the AI creates production-ready code instantly.
For this UTM builder prototype, AI Builder would generate the Gutenberg JSON structure, custom CSS for styling the form and preview area, and vanilla JavaScript for URL building, validation, localStorage management, and clipboard operations—all in seconds.
This approach is perfect for rapid prototyping. You can test ideas, gather feedback, and iterate quickly without writing boilerplate code. AI Builder handles the technical implementation while you focus on product strategy.
Prompt to Reproduce This Feature
Want to recreate this UTM builder in your own WordPress site? Copy the prompt below and use it with AI Builder:
Create a mini SaaS prototype: "UTM Link Builder with reusable templates." The page must include a working interactive demo built with vanilla JavaScript inside a single HTML block (no external libraries). Requirements: inputs for base URL + utm_source + utm_medium + utm_campaign + optional utm_content/utm_term; live preview of the final URL; validation for URL; a "Copy link" button; a "Save template" button that saves current UTM fields to localStorage; a "Templates" dropdown to load/delete saved templates; small success/error toasts.
