Links
Bulk UTM builder and checker
A batch of campaign links is easy to mistag by hand. Load your URLs, set shared tags and review the changes before launch.
1. URLs
Upload CSV
2. Shared tags
Empty fields preserve existing tags. By default, only missing values are filled.
Files and text are processed on your device and are not sent to the blog server. Individual tool settings are saved only in this browser.
How to use it
- Paste one URL per line or upload a CSV with a URL column.
- Set shared tags. Choose to fill missing values or replace existing tags.
- Review the original and prepared links, then copy or download the CSV.
This checks URL structure, not landing page availability or analytics delivery. Lowercasing only affects source and medium when you enable it.
Questions and answers
How do I import and export a batch?
Paste up to 500 URLs, one per line, or upload a CSV and select the URL column. Copy the prepared list or export it with original URLs and findings.
Can I keep existing tags and fill only missing ones?
Yes, that is the default. Enable the replacement option to overwrite tags. Empty fields preserve existing values. Optional lowercasing affects only source and medium.
Does the check confirm the landing page and tracking work?
It checks URL structure, missing tags and duplicate parameters. It does not open landing pages or inspect analytics events. Test the destination and tracking separately.
