UTM Link Builder

📖 About this tool

UTM parameters are the standard way to attribute traffic: adding source, medium, campaign, term and content to a landing page URL lets analytics tell how much traffic and how many conversions each channel delivered. This tool turns the assembly into a form, detecting whether the URL already carries a query string and joining with ? or & correctly, which avoids the formatting errors common when拼接 by hand. Values can be lowercased with spaces replaced by underscores so a channel is written the same way by everyone. Put one channel per line in the source list to generate many links at once; each can be copied individually, or the whole batch copied or exported as CSV for the media team. Everything runs locally. Typical uses include preparing投放 links for several channels in one campaign, keeping parameter naming consistent across a team, handing channel links to external partners in bulk, and checking the assembled URL before launch.

✨ Features

• All five parameters：Source, medium, campaign, term and content assembled together, empty ones skipped
• Detects existing query strings：Joins with & when the URL already has parameters, preserving its structure
• Consistent naming：Values lowercased with spaces replaced by underscores so one channel has one spelling
• Batch by channel：One channel per line in the source list generates every link at once
• Copy per link or export：Copy any single link, the whole batch, or export CSV

🚀 How to use

1. Enter the landing page URL;
2. Set source, medium and campaign;

4. Click Generate and copy or export.
