How to exploit this ranking

1. Pick 3-5 subs in 1-2 categories aligned with your niche. 2. Build karma on these subs first (see Karma Threshold). 3. Understand AutoModerator for each sub (see AutoModerator). 4.

To automate this workflow at scale, the managed Reddit Backlinks service handles account pool + warm-up + tracking.

FAQ

How many subs to target simultaneously? 3-5 max. More = dilution + pattern detection risk.

Does Reddit penalize cross-posts? Yes since 2023. Cross-posting the same content on 5 subs in 24h = guaranteed shadowban.

Are subs under 10k members worth it? Often yes: less aggressive mod, qualified audience, higher link acceptance.

Does international Reddit (r/france, r/UK) have SEO value? Moderate. Limited geographic traffic but cited by AIs in local language.
