Post a shortened link to most subreddits and it disappears. Not with an error, not with a message: the post exists for you, is invisible to everyone else, and you find out days later when the click count never moves.
The fix is unglamorous. Post the full canonical URL, put the campaign tags on it, and read the traffic in your analytics rather than in a link dashboard. We sell short links, and this is the one channel where I tell people not to use them. What follows is why the filters behave this way, how to confirm a removal, and how to measure Reddit without the tool you would normally reach for.
Why Shorteners Get Removed
Three reasons stack up, and none of them are about you.
A shortener hides the destination. A moderator scanning a queue can see example.com/guide and judge it in a second; a short link has to be opened, and nobody opens forty of them. Communities that grew tired of that made a rule.
The rules are enforced by AutoModerator, a configurable bot each subreddit runs for itself. Domain blocklists are one of its most common uses, and a shortener domain is on a lot of them. Because every community writes its own configuration, there is no single list to check and no way to be sure in advance except reading the rules in the sidebar.
Above that sits Reddit's own spam filtering, which reads the whole shape of a submission: account age, karma, posting frequency, and how often that domain has been posted lately. Reddit's content policy forbids spam in general terms, and the self-promotion guidance sets the cultural expectation that you participate in a community rather than broadcast into it. A new account posting shortened links across five subreddits in an hour matches the spam pattern precisely, whatever the content is.
How to Tell Whether You Were Removed
This is the part that wastes weeks, because removal is quiet by design.
Open the post in a logged-out browser window. If it does not appear there, or it is missing from the subreddit's new listing, it was filtered. Checking from your own account proves nothing, since removed posts commonly still render for their author.
Two other signals are worth watching. A post that gets zero views in an hour on an active subreddit was almost certainly removed rather than ignored. And if you have a click count on the link, a flat line while the post appears live to you is the same conclusion from the other direction.
What to Post Instead
The full URL, with tags. Concretely:
https://example.com/guide?utm_source=reddit&utm_medium=social&utm_campaign=launch
That link shows its destination to moderators and readers, matches nothing on a domain blocklist, and still attributes correctly on your side. Campaign parameters are not what the filters are looking for.
What to strip: affiliate identifiers, session tokens, and anything that makes the URL look like a tracking wrapper. Affiliate links are removed on sight in most communities and are against the rules in many, and link cloaking or masking is a fast route to a sitewide ban rather than a clever workaround.
One nuance about tags: keep them short and human-readable. A URL with eleven parameters reads as machinery even when it is honest, and moderators pattern-match too.
Measuring Reddit Without a Short Link
You lose the click count. You keep everything that matters.
The campaign tags on the URL do the attribution, so arrivals land in your reports as a Reddit row with a campaign attached. That covers the desktop web, the mobile apps and the third-party clients, which is more than referrer data manages on its own: app traffic frequently arrives with no usable referrer, and Reddit's own outbound redirect means the referring host is not always what you would expect.
Two habits make the numbers usable. Use a distinct utm_campaign per thread, so a post that quietly earns traffic for a year is separable from the one that did nothing. And check your landing page for parameter stripping, because a destination that redirects and drops the query string turns the whole exercise into direct traffic; why UTM parameters do not show in GA4 walks that failure down.
Everywhere else, the tracked link stays the better tool. Elido's link analytics covers the channels that do not fight you, and the tagging convention you use on Reddit is the same one, so the reports still line up.
The Rules Behind the Rules
Removal is not only about the URL. Four account-level factors decide as much as the link does.
- Karma and account age. Many subreddits gate link submissions behind a minimum, precisely to stop drive-by posting. There is no way around it except participating first.
- History shape. An account whose submissions are all one domain reads as a marketing channel. Comment somewhere you have no commercial interest, regularly, and the shape changes.
- Frequency. The same link across several subreddits in a short window is the single strongest spam signal available.
- Fit. A post that would be useful even if the link were removed tends to survive; one that is only a link does not.
Read the sidebar rules before posting, every time. They differ enormously, they change, and the ones that matter are usually specific: no links in the first week, no self-promotion outside a weekly thread, text posts only.
Where Short Links Still Belong
Reddit ads are a different surface with different rules, and tracking URLs are normal there. Your profile links, off-platform posts about a thread, and anything printed or spoken all keep the usual advantages of a link you own: readable, repointable, countable. What a branded link is covers those advantages, and where short links get blocked in Slack and Teams covers the other platform family that treats them with suspicion.
The rule I have settled on: if a human moderator will look at the link, show them the destination. Everywhere else, use the tracked version.

Frequently asked questions
Does Reddit block shortened links?
Reddit's sitewide spam filtering treats shorteners with suspicion, and a large share of communities configure AutoModerator to remove them outright. The result depends on the subreddit rather than on one global rule, and the removal is usually silent: your post looks fine to you and does not exist for anyone else.
How do I know if my Reddit post was removed?
Open the post in a logged-out browser window or a private tab. If it is not there, or the subreddit listing does not include it, the filter took it. Your own profile is not a reliable check, because removed posts often still show for the account that made them.
Are UTM parameters allowed on Reddit links?
Yes. Campaign parameters on a full URL are not what triggers removal filters, and they are the practical way to attribute the traffic. Keep them short and readable, and strip anything that looks like an affiliate or session identifier, since those attract a different kind of scrutiny.
How do I track Reddit traffic without a short link?
Put the campaign tags on the canonical URL you post, and read the arrivals in your analytics. Referrer data from the mobile apps is unreliable enough that the tags are the dependable signal, which makes tagging the full URL the whole method.
What is the self-promotion ratio on Reddit?
The old guidance was roughly one self-promotional submission for every nine ordinary contributions, and while it is no longer enforced as a single sitewide rule, moderators still judge accounts by that shape. An account whose entire history is links to one domain gets treated as a marketing channel, because it is one.
Can I use a branded short domain instead?
Sometimes, and it is still a gamble. A domain nobody recognises is exactly what the filters are tuned to catch, so a fresh short domain can be removed as readily as a generic one. Where the destination is your own site, posting the real URL costs you nothing and removes the risk entirely.
