Contextual Targeting

New Features

Sublime Ads now supports contextual ad targeting via the API.

If you’re building with LLMs, you can now pass conversation-aware signals when fetching ads, and get more relevant placements.

What's New

  • Context-aware ad serving on GET /api/ads using:
    • context
    • topic
    • intent
    • audience
    • locale
    • conversation_keywords
  • Smart fallback: if no contextual matches are found, we automatically fall back to the normal eligible ad pool.
  • AI-assisted targeting context generation in the ad editor:
    • Generate context from ad copy with one click
    • Loading state and quick insert into the targeting field
  • Updated docs with:
    • A new contextual targeting section
    • An example system prompt for LLMs that call Sublime Ads
    • Updated API examples for contextual requests
  • Demo endpoint (GET /demo/ads) now supports contextual params too, so you can test relevance without auth.

Example Request

curl -H "Authorization: Bearer YOUR_TOKEN" \
  "https://sublimeads.com/api/ads?format=json&count=2&topic=ruby&intent=learn&audience=developers&locale=en-US&conversation_keywords=rails,api,hotwire"

Why This Matters

LLM experiences are context-first. Ads should be too.

With this release, you can keep ad delivery lightweight and API-first while making placements more relevant to what users are actually discussing.
