How Reddit's Algorithm Actually Works in 2026

I've been posting on Reddit for about six years now. For the first four, I had no idea what I was doing. I'd write something I thought was genuinely useful, hit publish, and watch it sit at 2 upvotes for eternity. One of those upvotes was mine.

Then I started paying attention to how Reddit's algorithm works under the hood, and everything changed. Not overnight, but enough that I went from mass-posting into the void to consistently getting posts into the top 10 of mid-sized subreddits. Here's what I figured out.

Reddit cares about the first hour more than anything

When you publish a post, Reddit gives it a small window of initial exposure. Think of it like a trial run. Your post gets shown to a handful of people in the subreddit, and what happens next determines everything.

If those first few people upvote it, leave a comment, or give it an award, Reddit's algorithm reads that as a signal. It pushes the post to more people. Those people engage, and the cycle keeps going. That's the momentum phase, and it's where posts either take off or quietly die.

I tested this myself. I posted the same type of content at different times and tracked what happened. Posts that got 3-4 comments in the first 30 minutes almost always outperformed posts that got the same number of comments spread over 3 hours. Speed matters. The algorithm is watching how fast engagement comes in, not just how much.

Each subreddit is its own little ecosystem

One thing that tripped me up for a long time was treating all subreddits the same. They're not. A post that works in r/marketing will bomb in r/entrepreneur even if the topic overlaps.

Every subreddit has its own culture, its own posting norms, and its own algorithmic quirks. Some subreddits heavily weight upvote velocity. Others seem to favor comment depth, meaning threads where people actually go back and forth. I've seen subreddits where a post with 15 upvotes and 40 comments outranks a post with 200 upvotes and 3 comments.

The mods matter too. Some subreddits have automod rules that shadow-remove posts from new accounts or accounts with low karma in that specific subreddit. You won't even know your post got removed. It just never gains traction and you assume nobody cared.

Video is getting pushed hard right now

This is the big shift I've noticed in 2026. Reddit has been quietly giving more weight to video content. If you scroll through popular feeds now versus a year ago, you'll see way more native video posts ranking high.

I think Reddit is trying to compete with TikTok and YouTube Shorts, and the algorithmic boost for video is part of that. I started experimenting with short video posts in a few subreddits where I usually post text, and the reach difference was noticeable. Not massive, but enough that I keep doing it.

That said, this doesn't mean you should force video where text works better. If you're in a subreddit where people expect detailed written answers, a random video will feel out of place and probably get downvoted. Read the room.

Google changed the game for Reddit content

Here's something a lot of people miss when they think about how Reddit's algorithm works. It's not just Reddit's internal algorithm that matters anymore. Google has been featuring Reddit results more and more in search. You've probably noticed it yourself. Search almost anything with a question and there's a Reddit thread on page one.

This means your Reddit posts have a second life. A post might get moderate traction on Reddit itself but then pull in steady traffic from Google for months. I have posts from late 2025 that still get comments from people who found them through Google search.

This changes how you should think about writing on Reddit. It's not just about going viral in the subreddit. If you write a genuinely useful answer to a question people actually search for, the Reddit algorithm and Google's algorithm both work in your favor.

What actually matters when you post

Engagement is the whole game. Upvotes, comments, awards, all of it feeds the algorithm. But here's the part nobody talks about enough: the type of engagement matters.

A post that gets 100 upvotes and no comments doesn't perform the same as a post that gets 50 upvotes and 30 comments. Comments signal to Reddit that people care enough to respond, and responses to responses signal even more. The algorithm loves threads.

I've started writing my posts to end with something that invites a real response. Not "what do you think?" because that's lazy and people scroll past it. More like sharing a specific opinion I know people will disagree with, or asking about a specific experience. Friction creates comments. Comments feed the algorithm.

The honest version

I won't pretend I've cracked some secret code. Reddit's algorithm changes, the weight of different signals shifts, and what works in one subreddit fails in another. But after years of paying attention, the pattern is pretty clear: make something people want to engage with, post it when your audience is active, and let the first hour do the heavy lifting.

The algorithm rewards real engagement. That hasn't changed, and I don't think it will.
