Paste a link above to see which tracking codes it carries and what each one does.
The utm codes
utm_source, utm_medium, utm_campaign, utm_term and utm_content are added by marketers so their analytics can tell where visitors came from. For example, utm_source=newsletter&utm_medium=email says the click came from an email newsletter. They usually describe a campaign rather than a person, but they still tell the site where you found the link. The name comes from Urchin, the analytics company Google bought that became Google Analytics.
Click IDs
fbclid (Facebook), gclid (Google Ads), msclkid (Microsoft Ads), ttclid (TikTok) and twclid (X) are unique to a single click. They let the ad network connect your visit to the ad or post you clicked on their platform.
Email and subscriber codes
Some codes are tied to you personally. Mailchimp's mc_eid identifies the subscriber, Marketo's mkt_tok is linked to your email address, and HubSpot's _hsenc and _hsmi track who clicked from which email.
Share codes
Spotify and YouTube add "si" to shared links, which can link the share to the account that shared it. Instagram adds igsh for the same reason.
Can I delete them?
Yes. These codes are for the site's records, not for showing the page, so removing them doesn't change what you see. Link Unmasker gives you a clean copy of any link with the tracking codes taken out.
Guides
What this can't do
- It can't tell you a site is safe. It shows where a link goes, not whether the page there is honest. Check the final address yourself, letter by letter.
- Some redirects need a full browser. Pages that run a lot of code before moving you on, or that ask you to click a button, stop the trail there. We show the page we reached.
- Some sites block automated visits. They may show a "checking your browser" page or an error instead of what you'd see.
- Links that need you to be logged in end at a sign-in page here, because we never use your accounts.
- It doesn't see tracking inside the final page, such as analytics scripts and ad pixels. Only the redirects, address codes and cookies on the way.
