How to Write Effective Signal Criteria in Radar

Last updated: June 30, 2026

What are Signal Criteria?

Signal criteria are a critical building block of your product profiles. This is where you explain what you want your signals to look for and match.

Key Takeaways

  1. this is the primary area to tweak and control what signals get surfaced

  2. rough target of 15-30 criteria (not a hard and fast rule but general guidance)

  3. The best signal criteria are those that are as explicit as possible, semantically, to what you want the source documents to surface

Steps

  1. Write each as a phrase or sentence using the language of your customer(s)

  2. Phrase your criteria in the language your target documents actually use

    1. e.g. "line item for [competitor product] subscription costs is stronger than "agency interested in [competitor product]"

  3. Keep each criterion to one idea

  4. Describe what you're looking for and the category it belongs to.

    1. If your target could be confused with a similar one, add a word that pins it to your audience — like "college" to keep a higher-education search out of K-12 results

  5. Set each criterion's priority from 1 to 5, where 5 is highest, based on how directly it targets what you want

What Success Looks Like

You're getting signals that point to real intent and activity

Common Issues

Results outside your target: strengthen the name, category, or audience-specific word in the criterion.

Fewer signals than expected: focus on your strongest criteria rather than adding more lines.
