Step 1
What it checks
The checker scores discussion potential, title curiosity, stakes, comment catalysts, and weak spots.
Free Reddit tools
Reddit virality checker
Test a Reddit post's discussion potential before posting and find the hooks that could make people reply.
Virality is a prediction, not a guarantee. Reddit timing, audience mood, and moderation can change the outcome.
How it works
Each Rankhog tool turns one Reddit decision into a short workflow: add context, review the result, then decide whether to post, rewrite, wait, or move into Rankhog.
Step 2
How to use it
Paste a title, idea, or draft. The result suggests stronger hooks and comment prompts.
Step 3
What the output means
Use this as a secondary editing pass. Rankhog prioritizes safe, useful visibility over chasing viral posts.
Example input and output
The live tool runs with your own context. This example shows the kind of practical answer you can expect.
Sample input
- Post idea
- We cut support tickets by rewriting onboarding emails
Potential: medium
The idea has discussion potential if the title makes the tradeoff obvious.
- Specific outcome helps
- Add stakes in the title
- End with a question founders can answer
Use it with subreddit-specific context
Pair the tool with Rankhog's subreddit guides when you are posting somewhere strict. The guides cover rules, stats, what works, and removal risks.
