Reddit’s immune system attacks opaque links, new domains with no history, and mismatch between post title and destination. Short links are fine if they read as human and land where you said.
Transparency beats stealth
State the destination domain in text: “Full write-up on my site—brand.link/guide.” Slugs that mirror the topic help moderators preflight your intent.
One community, one norm
Read sidebar rules. Some subs ban all shorteners; others allow branded ones. When in doubt, ask mods with a long URL and offer a short mirror for comments if permitted.
Value before CTA
The link should support a detailed comment or post: data, diagrams, code. Drive-by drops fail regardless of URL length.
Long-term reputation
Consistent short paths on posts that help accumulate account trust. Random churn of domains looks like fly-by-night marketing.
Octilink emphasizes speed and readable paths—useful when you participate authentically and need a tidy link in a technical comment.
