About this tool
Paste or upload your campaign URLs (one per line, or a CSV containing links). The auditor checks each link for missing utm_source, utm_medium or utm_campaign, capital letters, spaces and mixed separators, repeated parameters and empty values, then finds inconsistent spellings of the same source or medium (such as Facebook, facebook and fb) and duplicate links. It exports a cleaned list of links with consistent lower-case values. Your files are read in your browser and never uploaded.
UTM Link Auditor is part of ToolStack Hub's SEO & Marketing Tools. It runs entirely in your browser, which keeps your data private and makes results instant. There is nothing to install, no account to create and no usage limit.
Frequently asked questions
Which UTM parameters are required?
utm_source, utm_medium and utm_campaign are the three most analytics tools expect. utm_content and utm_term are optional.
Why does letter case matter?
Analytics tools treat Facebook and facebook as different values, which splits your reports. Keeping everything lower case avoids that.
Is the UTM Link Auditor free?
Yes. UTM Link Auditor is completely free with no sign-up, limits or watermarks.
Is my data private when I use the UTM Link Auditor?
Yes. It runs in your browser, so your input is not uploaded to our servers.
Does it work on mobile?
Yes. ToolStack Hub tools work on phones, tablets and desktop browsers.
