Tracking parameters are extra bits added to a URL to measure where a click came from, which ad was shown, or which email recipient opened a link. Common examples include utm_source, fbclid, gclid, mc_eid, ref and _ga. As of April 2026, stripping them will usually not break the page itself, but it can reduce cross-site attribution, make links shorter, and stop you from forwarding identifiers that were attached to your click or inbox. The practical rule is simple: keep the part before the question mark when the rest is only tracking, or use a tool that removes known junk safely.
What tracking parameters are and why they matter
A URL has a base address and, often, a query string after a ?. In https://example.com/article?utm_source=newsletter&utm_medium=email, the query string starts after the question mark. Those key-value pairs are not inherently bad; some are needed for search, language selection, pagination or product filters. The problem is that many are only there to attribute your click.
As reported by Google in its Campaign URL Builder documentation in 2025, utm_source, utm_medium, utm_campaign, utm_term and utm_content are standard campaign tags for analytics. As reported by Meta in its developer and ads documentation in 2024, fbclid is a click identifier appended to outbound links from Facebook properties. As reported by Google Ads Help in 2025, gclid is Google’s click identifier for ad measurement. As reported by Intuit Mailchimp in 2025, mc_eid can identify an email recipient for campaign tracking.
A concrete example: if you copy a newsletter link like https://shop.example/sale?mc_eid=123abc&utm_source=newsletter&utm_medium=email, forwarding it passes along both the campaign tags and a recipient-linked identifier. Removing the query string gives https://shop.example/sale, which will normally load the same page.
The most common tracking parameters
The table below covers the ones you will see most often. Some names are standard across the web; others are vendor-specific. As of April 2026, none of these are required to display the destination page in the usual case.
| Parameter | Common system | What it does | Usually safe to remove? |
|---|---|---|---|
utm_source | Google Analytics-style campaign tagging | Records traffic source | Yes |
utm_medium | Google Analytics-style campaign tagging | Records channel, eg email or cpc | Yes |
utm_campaign | Google Analytics-style campaign tagging | Records campaign name | Yes |
utm_term | Google Analytics-style campaign tagging | Records keyword or audience | Yes |
utm_content | Google Analytics-style campaign tagging | Distinguishes ad or link variant | Yes |
utm_id | Google Analytics-style campaign tagging | Campaign identifier | Yes |
fbclid | Meta/Facebook | Click identifier for outbound links | Yes |
gclid | Google Ads | Google ad click identifier | Yes |
dclid | Google marketing stack | Display ad click identifier | Yes |
msclkid | Microsoft Ads | Microsoft ad click identifier | Yes |
mc_eid | Mailchimp | Email recipient/campaign identifier | Yes |
mkt_tok | Marketo/Adobe | Marketing attribution token | Yes |
vero_id | Customer messaging tools | Visitor/email campaign identifier | Yes |
_ga | Google Analytics linker | Cross-domain measurement value | Yes |
igshid | Instagram share links | Share/click tracking value | Usually |
si | YouTube and other platforms in some contexts | Share or session-style identifier | Often |
ref / ref_src | Affiliate/referral/internal attribution | Referrer label | Often |
The two parameters to treat more carefully are generic ones such as ref and source. Some sites use them for harmless attribution; some use them for routing or support flows. If removing ref=support breaks a help-centre journey, put it back. If removing ref=twitter changes nothing, leave it out.
How to strip tracking parameters manually
The fastest method is still manual editing. It takes 5 seconds once you know what to look for.
- Copy the full URL.
- Look for a
?. Everything after it is the query string. - Remove known tracking pairs such as
utm_*,fbclid,gclid,mc_eid,_ga. - If several parameters exist, they will be separated by
&. - Test the cleaned URL before sharing if the page is important.
Example:
- Original:
https://news.example/story?utm_source=twitter&utm_medium=social&fbclid=IwZXh0bgNhZW0CMTAAAR1... - Cleaned:
https://news.example/story
If a URL contains both useful and tracking parameters, keep the useful ones. Example:
- Original:
https://shop.example/search?q=ssd&utm_source=newsletter - Cleaned:
https://shop.example/search?q=ssd
The key distinction is intent. q=ssd changes the page. utm_source=newsletter does not. In a typical ecommerce URL with 4 parameters, 1 may be necessary and 3 may be disposable.
A simple rule works well: if a parameter starts with utm_, remove it. If it is a known click ID like fbclid, gclid or msclkid, remove it. If it looks like search, page, sort, product, language or currency state, keep it until tested.
Using ClearURLs in your browser
If you do this more than a few times per week, an extension is quicker than manual editing. ClearURLs is one of the better-known options because it strips known tracking parameters automatically and can clean links before you open or copy them. As of April 2026, ClearURLs is open source and its filter rules are publicly maintained on GitLab.
The trade-off is convenience versus control. Manual removal is precise but slow. ClearURLs is faster across hundreds of clicks but depends on a maintained ruleset and browser-extension permissions. For a heavy web user opening 50 tracked links per day, the extension approach saves time immediately. For someone who only cleans a few newsletter links each week, manual editing may be enough.
A few practical points:
- Check the extension permissions before installing.
- Review whether it rewrites links automatically or only on demand.
- Keep an eye on breakage on sites with complex query strings.
- Prefer open-source tools with public issue trackers over opaque “privacy cleaner” extensions with no code or changelog.
ClearURLs versus manual stripping is straightforward: ClearURLs wins on speed; manual stripping wins on certainty. ClearURLs versus a share-link cleaner tool is also straightforward: the extension helps during browsing, while a web tool is better when you want a clean URL to paste into chat, email or notes.
Using NoTrackr’s free tool for safe sharing
If your goal is share-link hygiene, use our free tool: https://tool.notrackr.com/. It is the easiest option when you have a long URL from email, social media, a shopping app or a copied address bar and want a cleaner version before sending it on.
Paste the URL, let the tool remove known tracking parameters, then copy the cleaned version. This is especially useful for links with 6 to 12 parameters, where manual editing is annoying and mistakes are common. It also avoids the main extension downside: always-on browser permissions.
This is the best workflow for three common cases:
- Forwarding newsletter links: remove
mc_eid,utm_*and similar campaign tags. - Sharing social links in chat: remove
fbclid,igshidand related identifiers. - Saving research links: keep the canonical page URL instead of a cluttered tracking version.
If you routinely clean links before posting them publicly, bookmark https://tool.notrackr.com/. It is the practical middle ground between editing URLs by hand and handing continuous access to an extension.
When not to remove parameters
Not every query parameter is tracking. Some are functional. Removing the wrong one can change the page or empty a basket.
Common examples of functional parameters include:
q=for search queriespage=for paginationlang=orlocale=for language selectionsort=for ordering resultscolor=orsize=for product variantstoken=or one-time login/reset values
A concrete scenario: https://store.example/product?id=42&color=blue&utm_source=email should usually become https://store.example/product?id=42&color=blue, not just the bare product path. Likewise, never strip a password-reset or magic-login link unless you want to break it.
There is also a privacy limit worth stating clearly. Removing tracking parameters stops you from sharing obvious identifiers in the URL, but it does not block all tracking. The site can still log your IP address, browser details, referrer policy permitting, and any account you sign into. As reported by Mozilla Support in 2025, browser-level query parameter protections can reduce some of this leakage, but they do not replace sensible browsing habits or tracker blocking.
What to do next
Start with the low-risk habit: delete utm_*, fbclid, gclid, mc_eid and _ga before you share links. If you do that more than a few times a week, test ClearURLs in one browser profile. If you mostly want clean links to paste into messages, use https://tool.notrackr.com/ and keep functional parameters like search terms or language settings when they matter. The right goal is not perfection. It is to stop forwarding unnecessary identifiers by default.
