Similar-topic warning before new support thread
Use the composer’s similar-topic warning so users see likely answers before they create another near-duplicate support thread.
Why this can grow a startup
Duplicate support topics do not only waste moderator time. They also split search equity and force future readers to pick between several half-overlapping answers. Discourse surfaces similar topics while someone is composing a new thread, with settings for title length and how much existing topic volume is needed before suggestions appear. That small interruption can save a forum from steady answer fragmentation. It is one of the cheapest ways to protect both support bandwidth and the public answer archive.
Source-backed example
Discourse documents a composer message that warns users when a new topic looks similar to existing topics and shows possible matches before posting.
Source-reported evidence
Source: Discourse Meta: Composer Popup Messages Guide
The similar-topics composer message is controlled by settings for minimum title length and minimum existing topic count.

When to use it
Use this when Support, SEO, Community is relevant to duplicate prevention, forum seo, support deflection and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
How to do it
- Choose one target segment and define the exact next action this tactic should prompt.
- Adapt the tactic to Support and SEO, using evidence from Discourse Meta: Composer Popup Messages Guide as context—not as a promised result.
- Record a baseline for: Qualified search visitors who complete the intended next action. Set a guardrail that would make you pause the test.
- Run a narrow pilot and choose a test window that fits the normal decision or use cycle; do not scale before you have observed the full cycle.
- Compare the signal with its baseline. Scale only if the intended action improves without crossing the guardrail; otherwise revise one variable or stop and record what you learned.
