What is a URL parameter?

A URL parameter is a name-value pair after the question mark of an address – some parameters control the page, others only measure the click.

Local-first: No upload, no cloud, no AI – the cleanup happens directly in your browser, on your device.

The short answer

A URL parameter is an extra in a web address that consists of a name and a value. The first parameter starts after a ?, further ones are joined with &.

?q=hiking+boots&lang=en

Parameters can serve different purposes: they can be functional, analytical, presentation-related or state-related. Functional parameters control the page – such as search, filters or language – while measuring parameters attribute a click or campaign, such as utm_source or click IDs.

That is why parameters should not be deleted blindly. Removing everything after the question mark can remove search, filters or settings as well.

Before / After

Before

https://example.org/search?q=hiking+boots&utm_campaign=summer

After

https://example.org/search?q=hiking+boots

Try it yourself: Copy this test link, paste it into RALIMU and compare original and result. The campaign parameters are unnecessary – q=hiking+boots stays, because otherwise the search would be empty.

https://example.org/search?q=hiking+boots&utm_campaign=summer&utm_source=mail

Functional or measuring?

Functional parameters

Control what the page shows: search (q), language (lang), page number (page), filters like color. Without them the link no longer shows what you meant.

Measuring parameters

Attribute the click to a source or campaign: utm_source, utm_campaign, click IDs like gclid. The destination of the link works without them.

Rule of thumb: If the parameter visibly controls the content, it is functional. If it only attributes the click, it is usually unnecessary when sharing.

What RALIMU removes – and what stays

Not every parameter is pure tracking. Some keys are functionally necessary, for example for language, search, filters, variants or IDs. That is why it is better to check links instead of simply deleting everything after the question mark.

Typically removable extras

utm_source
utm_medium
utm_campaign
utm_term
gclid

Handle with care

Search terms (e.g. q)
Language settings (e.g. lang)
Page numbers (e.g. page)
Filters (e.g. color)
Product or variant IDs

RALIMU is not meant to break links. The app helps make recognizable link extras visible and use cleaned links deliberately.

How to clean the link

Three ways, depending on your device. The check runs local-first – the link does not have to be uploaded to a RALIMU server for this.

iPhone & iPad

Copy the link or pass it on via the share menu.
Run the RALIMU shortcut.
Paste or share the cleaned link directly.

Free shortcuts

Android

Copy the link from a browser, app or messenger.
Open RALIMU in the browser and paste the link.
Copy and use the cleaned URL.

Open RALIMU

Desktop

Copy the URL from the address bar.
Paste it into RALIMU or use a RALIMU bookmarklet.
Check the result and copy the cleaned link.

Honest scope

Yes: RALIMU reduces recognized tracking and click parameters in URLs before sharing.
No: RALIMU is not a VPN, not an ad blocker and not complete tracking protection.
In short: a concrete hygiene step – not a promise of invisibility.

When a quick check becomes a workflow

For individual links, RALIMU Free is enough – permanently and free of charge.

If you regularly check, explain or document links before sending – for example in newsletters, editorial content, customer communication or team approvals – RALIMU Link Review is the next step: understand, check, document.

Your newsletter tool checks whether the link works.
RALIMU Link Review shows what is inside the link.
