YSK: Social media platforms attach trackers to the end of share URLs (which you can and should delete)

Why YSK: Trackers don't do good for anyone except the platform, and they're not necessary to view the content in the URL.

It's courteous to not subject the recipient (most likely your friends and family) to this tracking. You're already sending them to the platform, which is tracking them in other ways. But you can help reduce that tracking by removing everything after the ampersand in the URL. Here are some examples.

Twitter example

URL: https://x.com/CookieSlayers/status/1623712884902567937?s=20

The s=20 is a Twitter-specific parameter to show that the tweet was copied from the web app. s=46 is iOS, and I can't remember what Android's code is. This is a relatively clean link, but there are some links that'll concatenate unique identifiers, like: https://x.com/CookieSlayers/status/1623712884902567937?s=20&t=Fn47fnSDJUD74bd9.

In this case, you'll notice there's also a &t= parameter, which is a unique identifier to the person who shared it.

The only part of the URL you need is https://x.com/CookieSlayers/status/1623712884902567937.

Instagram example:

URL: https://www.instagram.com/reel/CzP877du2EB/?igshid=MzRlODCFWFlZA==

The only part of the URL you need is https://www.instagram.com/reel/CzP877du2EB.

TikTok example

URL: https://www.tiktok.com/@inthepaintcrew/video/7301348328602717482?is_from_webapp=1&sender_device=pc&web_id=7302915057791436331

You'll notice TikTok's is a lot more readable in terms of what the URL contains.

The is_from_webapp parameter is self-explanatory, as is the sender_device, and then there's the identifier that's unique to you. In this case, 7302915057791436331.

The only part of the URL you need is https://www.tiktok.com/@inthepaintcrew/video/7301348328602717482.

The best route¹ would be to use privacy-respecting frontends, but if you don't, simply deleting everything after the ampersand goes a long way.

¹The best route would actually be to not use/reward platforms that are literally destroying humanity, but we're not there yet, so... in the meantime, let's just try to decrease the tracking and stop subjecting our friends and family to it as much as possible.

Tldr, anything after a '?' In a url is unnecessary.
- Not always, but it's a good rule of thumb.
- It's getting worse too. Recently I've noticed Reddit links from friends looking like:
  
  reddit.com/r/example/s/1234567
  
  Which then redirects to the actual reddit.com/r/example/post/comments/1938473
  
  I believe Spotify and Tiktok do short tracker-filled links like that too. If you're on android, URLCheck can wrangle those links to find the actual content without the trackers. I've set it to intercept all clicked links so I can modify as needed.
  
  On web / iOS, I'm not sure
  
  I haven't checked how reddit does this but just from the example it seems like there is no anti tracking from the use of urlcheck that you're describing.
  
  reddit appears to generate tracking link with a specific numeric identifier in their database, so instead of attaching a bunch of removable url parameters they instead do a lookup in their database and then redirect to the original destination.
  
  this also means your app checking the redirect will need to fetch the url to determine the destination, which means their tracking still works just fine.
  
  edit: a word
- No, this applies to these specific parameters. Removing question marks and ampersands from urls will often break the pages if you don't know what you're doing or don't know what the parameters are for.
- On YouTube, adding "&t=37s" starts the video at 37 seconds. It is pretty useful.
  
  That is the full extent of my coding knowledge.
  
  I don't know why "amp;" appeared. I didn't write it and it is not necessary. It's just the and symbol. Followed by t=__s
- Not true on every site. Try it in your browser without the query string first before assuming that's the case. The app I work on, for instance, uses the query string to set date/time ranges and filter data.
- Except when it's not.
- Though I've always wondered if that's always consistently the case, and when that's not the case is there any mostly consistent way to identify the separator symbol in the URL text strings :/
I use this installable web app for cleaning extra parameters from links - https://linkcleaner.app/

Adds a share target to Android once you install it as well, makes it easy to send links to. Open source too!
- That sounds useful. Although I always fix them, I do get tired of squinting at urls looking for the &.
- Anyone have an Android version of this?
  
  I found URLCheck recently. It's great!
  
  I use https://play.google.com/store/apps/details?id=com.svenjacobs.app.leon
  
  It's an installable PWA, click the ... Menu in Chrome browser and choose "install". Hope this helps!

- What i do when sharing from an app would be to use a url cleaner app first and then share the cleaned link.
  
  This is the app i use https://play.google.com/store/apps/details?id=com.svenjacobs.app.leon
- Came here for this
I've found the android app URLCheck to be useful for this. You set it as your default Web browser and it lets you check for redirects before you open the link
- Yeah, I also recommend URLCheck on Android. You make it your default web browser and you can manually or automatically have the query string removed. It can do other stuff such as resolving redirects before sending it to a web browser.
  
  Or you can use it to clean the URL before sharing it.
I will add to this that UTM tracking is a little less invasive. I have gotten my boss to use UTM codes instead of full-blown tracking so we can at least capture which ads people clicked on and on which platform without capturing any personal data. As long as you pay attention to the other tags, UTM are reasonable from what I have seen in my research. Gives enough info to let the business know what is going on without letting them know who is doing it.
- That said, I use ScriptSafe on Chrome and a similar one on Firefox to ban the tracking code on websites entirely (along with anything that is not 100% necessary to view the page), so even if there are codes in the URLs I open, they are never logged by the analytics services that capture it.
  
  I suggest it to everyone. Block the scripts. It is a pain in the ass whenever you go to a new page, but you have the opportunity to see what off-domain script sources are attempting to execute and you can research the sources, then decide if you want to allow them to execute or not, and decide if you want to associate with a page before you give them much of anything. Overall, distrust google tag manager, Google Analytics, and literally anything that has "ad" in it and you get about 60% of the nasty out of the way.
  
  Fuck cutting the snake off at the head, I for his damn balls. Seems to work too as what advertising I do see, usually while casting streams, is all over the map. I get ads for video games next to ads for hip replacements, and I smile knowing that I have ghosted them as effectively as I can without going off grid.
  
  Not familiar with ScriptSafe—wonder if anyone here can confirm it's necessary if you're already using uBlock Origin. I would err on the side of "no," but you never know.
- Indeed, not all UTM tracking parameters are harmful. For example, you could have parameters like ?src=email&campaign=summer2023 that would denote how users engaged with the URL, without necessarily identifying them.
  
  Many platforms, however, will try to identify you and collect as much as possible.
  
  That is how we use them.
Just to add, the part of the URL that goes like “/foo/bar/123/article/whatever_blah_blah” is called the “path” and the part that looks like “?foo=bar&t=12345&flavor=chocolate&priceInCents=350&etc=etc” is called the “query string”.
I searched up this and am pasting it in again to get rid of the tracking:

  Good bot
What if you modify the tracker, like change some letters? Could that mess up their system if many did it?
- I like the way you think
  
  Garbage in, garbage out.
  
  "In computer science, garbage in, garbage out (GIGO) is the concept that flawed, or nonsense (garbage) input data produces nonsense output"
- If you go that route, start collecting real ids of loads of random people and then randomly add those. If you add invalid ones, they'll just get ignored, but with real random ones it really will fuck with their systems
- A few years ago, I came across a tool that did exactly this. It might've been a browser extension... When you clicked a link that had trackers, rather than providing a clean URL, it sent incorrect/invalid parameters to the tracking link.
If you want to remove parameters from urls you can use the removeparam filter in uBlock Origin. Documentation: https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#removeparam

For example: /?igshid=$removeparam=igshid,domain=instagram.com

For the best performance it's recommended to make sure the parameter is included in the filter as seen above with /?igshid, and with the domain it originated from.

Filters for the examples in OPs post:

/?igshid=$removeparam=igshid,domain=instagram.com ?is_from_webapp$removeparam=is_from_webapp,domain=tiktok.com &t=$removeparam=/^amp;/,domain=x.com

There's also a filter that removes a lot of known params: https://github.com/DandelionSprout/adfilt/blob/master/LegitimateURLShortener.txt
I personally use an app called URLCheck on Android (link)

Replaces your default browser handles and lets you manipulate the URL before it goes to your actual browser.
- F-droid link: https://www.f-droid.org/packages/com.trianguloy.urlchecker/
Apps should just strip these for us?
- Firefox does exactly that, in beta at least. When you copy a URL one of the options is to copy without trackers.
- That's exactly what URLCheck does on Android, acts like a middleman for links and allows you to strip tracking parameters etc, before forwarding you to another app to view the link's contents
Lemmy does not. So, just dump these other social media scams.
- Google search does it too. Hangouts used to. Not sure about Messages and other Google services.
  
  Fuck Google AMP as well.
  
  Even Wikipedia does it. I think it's to see what platforms people are using it on
YouTube has also started attaching a Share ID of sorts:

https://youtu.be/dQw4w9WgXcQ?si=rzmQCXsZkblahblah

The "si" query parameter is the tracker in question.

Presumably, it has your user ID embedded in it so all your efforts to concele your identity by using anon IDs on Lemmy/Reddit/Twitter etc routing through VPNs Tor whatnot can be shattered with a single share of a YouTube video. Plus, they can track and associate users with each other based on who all opened your link.
- Thank you senpai next lesson ?

  Bad bot you included the trackerz
- Really don't wanna be that guy but I think si stands for - source identifier, correct me if I'm wrong though.
  
  Yeah that seems plausible.
does anybody bother with blocking javascript anymore, like with noscript.net on firefox?
- Im using uBlock (Medium Mode) and JShelter (Strict Mode). It's an awesome combination, mixed with Firefoxs already existing anti tracking and resist fingerprint setting (default on Librewolf)
  
  NoScript isn't very popular anymore since it breaks many Webpages. Only exception is Tor, which comes with NoScript by default. Also there's uBlock, uMatrix, LibreJS and many more to block scripts nowadays
  
  noscript breaks webpages on purpose, because it blocks javascript
Amazon does it as well when you share an article.
- The op is about social media sites, but almost every site does it. Amazon, news sites, just about anything Google, Facebook.
  
  Shopping sites all do so they can track you across their platform even if you are not signed in. 'You looked at (premium) Widget, then (bargain) Widget'. They will probably show (mid-priced) Widget somewhere on that page then. If you click an external link on that page it will have tracking parameters along with it.
- How do we know which links would have this? What is the connection Amazon has to an article? I’m confused, I thought this meant only if you are sharing a link from a social media site.
  
  Some random article from the Amazon Android App:
  Share button: https://amzn.eu/d/2Ok2Czn
  Clicking the link: https://www.amazon.de/dp/B0BZ5RRT1B?ref_=cm_sw_r_apan_dp_F70NMAH6BZPA74X38C31&language=de-DE
  Cleaned link: https://www.amazon.de/dp/B0BZ5RRT1B
  
  Affiliate links I'm assuming but I'm not sure
I search up this link that helps spread to word about getting rid of trackers:

- Your link has tracking in it tho. You dont need the ?si= part
  
  Yup. I caught that after I clicked send. Oops
