Inside this guide

Short cards you can read in order or jump straight to. Tap the link icon on any card to share just that part.

01

Learn why Reddit is different

Reddit runs on communities called subreddits, and each one has its own rules and culture. Redditors prize honesty, expertise, and humor, and they are quick to reject anything that feels fake or promotional.

On Reddit, you grow by being truly useful, not by being loud.

02

Find your subreddits

  • Search Reddit for your interests and areas of expertise
  • Ask AI for related subreddits, then vet each one yourself
  • Compare member counts and activity levels
  • Choose three to five communities to focus on
03

Read the rules first

  • Find each subreddit’s own rules in its sidebar or About tab
  • Expect many to limit self-promotion or links
  • Check for minimum karma or account age requirements
  • Have AI summarize long rules, then read the key parts yourself
04

Use AI for research

  • Summarize long threads before you jump in
  • Spot the questions a subreddit asks most often
  • Check Reddit Answers, Reddit’s AI search, for what the community has already said
  • Verify facts before you share them
05

Write helpful comments

  • Answer questions from real experience
  • Add details, examples, and sources
  • Admit what you do not know
  • Write in your own voice, not an AI voice

Here is my draft comment. Make it clearer and shorter, keep my experience and my tone, and cut anything that reads like marketing.

06

Write strong posts

  • Write clear, specific titles
  • Share stories, guides, or questions that help others
  • Pick the correct flair
  • Answer the comments on your posts
07

Start your own subreddit

  • Spot a gap: a topic that lacks a good community
  • Write clear rules and a welcome post
  • Seed the subreddit with useful posts
  • Invite people respectfully and within other communities’ rules
  • Draft rules, FAQs, and weekly discussion threads with AI
08

Moderate well

  • Set up AutoModerator for simple filters
  • Act on reports quickly
  • Bring in trusted moderators as the community grows
  • Stay consistent and fair
09

Never automate these

  • Bot-driven posts or comments
  • Mass-produced AI comments
  • Fake accounts or vote manipulation
  • The same post spread across many subreddits

Each of these breaks Reddit’s rules and can get you banned.

10

Follow a weekly routine

15 minutes of helpful comments in your chosen communities

The golden rule

Do not use AI to fake participation. Use it to understand communities faster, so your real contributions help more people.

  • Rules
  • Research
  • Comments
  • Posts
  • Community
  • No bots

Choose three subreddits today, read their rules, and leave three truly helpful comments.
