Best Subreddits to Promote a YouTube Channel

You can promote your channel content, but only under clear conditions. The sidebar says, "Rule 1: No Link Dumping" and adds that you can promote your channel in community growth threads "provided you support other members of the community," and it also says, "It is required that you view other videos if you post your own."

You generally should not promote your product in r/Twitch. The rules are especially restrictive under Rule 2, "Advertisement Guidelines," which say "Don’t post an account name or link," "Don’t post tools, apps or services without prior mod permission," and "Don't post a link to a YouTube video, social media account, blog, or similar website." There is a narrow exception if you have prior mod permission for tools, apps, or services, and the sidebar also lists a "Services Megathread," so you should check whether your topic belongs in that megathread.

You should not promote your product in r/socialmedia unless your post clearly fits the subreddit’s professional discussion purpose and does not function as unsolicited promotion. Rule 6 says, "please refrain from unsolicited self-promotion or driving traffic to personal channels," and the submit page warns, "SPAM/Advertising/Selling Accounts = BAN." If you share links, Rule 4 also requires your own commentary, context, or analysis.

You cannot broadly promote your product in r/Instagram. Rule 6 says, "No self-promotion, F4F, S4S, C4C, L4L, giveaways, hacking services, ban/unban, verification, etc," and Rule 2 adds, "Don't post anything for sale here. We are not a marketplace." The rules do allow a narrow lane for introducing yourself and your profile in the weekly Introduction thread, and the submit page says to post links to your Instagram pictures, not links to your account directly.

You generally cannot promote your product in r/NewTubers. Rule 1, "No Self Promotion," says, "This is not a place to dump your videos and leave!" and only allows links to your content in the Weekly Feedback Friday and Self-Introduce Saturday megathreads, or in critique threads by other users. Rule 2, "No Advertising," also says advertising is not allowed without prior written authorization from the mod team, and that applies to third-party products, services, and market research.

No, you cannot promote your product freely in r/youtubers. Rule 3, "No self-promotion or engagement begging," says you may not link your own videos or channel except where explicitly allowed, and Rule 5, "No Spam, Surveys, Services, or Hoodwinkery," says posts or comments that exist primarily to sell, promote, or drive traffic to a product, service, app, platform, course, survey, or website are considered spam and you will be banned for it.

The rules provided do not address self-promotion directly. You can see posting limits and behavior rules, such as "You need at least 20 karma and 7 days of account age to post" in Rule 1, "Selling, buying or offering paid services of any kind is Not Allowed" in Rule 2, and "Do not spam" in Rule 3, but there is no explicit self-promo rule, so Reddit-wide norms also apply.

No, you cannot promote your product in r/Blogging under the posted rules. Rule 7 says, "Self-promotion, 3rd-party promotions & external links are not allowed," and the sidebar also says "No Promotions, Self-promotion or 3rd-party promotion isn't allowed." If your product is an ad, Rule 5 adds that "Advertising services or tools is disallowed without a moderator's approval."
