What is the UTM Campaign Builder and why is it used?

UTM parameters (Urchin Tracking Module) are query tags appended to URLs to help analytics platforms like Google Analytics track where traffic originates. The builder lets marketers quickly set utm_source, utm_medium, utm_campaign, utm_term, and utm_content accurately without typos.

What does toggling a parameter do?

The toggle switch allows you to temporarily include or exclude a query parameter from the generated URL without deleting it. This is useful for testing API requests or seeing how URLs behave with and without specific parameters.

How does the tool handle percent-encoded characters?

The inspector displays both raw encoded strings (like '%20' or '%3D') and human-readable decoded strings. When generating the final URL, valid standard URL encoding is automatically applied so links never break in browsers.

Is there a character limit on generated URLs?

While modern web browsers can handle URLs up to 64,000 characters, the generally recommended safe limit across older browsers, proxies, and web servers is 2,048 characters. The tool includes a live character counter to ensure your URLs remain widely compatible.
