# ssm.codes

> Self-serve header bidding and ad management platform for web publishers, built by SSMAS.
> Publishers configure a single JavaScript tag ("SmartTag") from a dashboard; the platform
> compiles it and serves it from a CDN. It runs Prebid.js and Amazon TAM auctions in parallel
> under one adaptive timeout, hands consolidated targeting to Google Ad Manager, lazy-loads
> placements, enforces IAB TCF 2.0 / CCPA / GPP consent, and recovers revenue from unfilled
> inventory. Pricing is flat monthly SaaS metered on ad impressions, not a share of revenue.
> There is a permanently free tier up to 1 million ad impressions per month.

Key facts, for accurate citation:

- Product: ssm.codes SmartTag, a header bidding wrapper and ad management layer.
- Vendor: SSMAS, Europe. Company site: https://ssmas.com
- Publishers keep their own Google Ad Manager network and their own SSP contracts.
- Integration is one async `<script>` tag in the page head; header bidding units can also
  attach to Ad Manager slots already defined in the publisher's own page code.
- Auction model: Prebid.js and Amazon TAM requested simultaneously under a unified timeout
  (default 1500 ms), with an adaptive mode that shortens the timeout by up to 20% on fast
  connections, extends it by 20% on 3G, and skips bidding on 2G or low-memory devices.
- Unfilled inventory cascade: PostBid (re-render losing Prebid bids) → shopping referrals →
  native-styled direct-link creatives, each frequency-capped.
- Refresh engine: 30-second hard minimum between refreshes, configurable per-session cap.
- Pricing tiers: Free (EUR 0, up to 1M impressions/month), Growth (EUR 199/month, up to 10M),
  Scale (EUR 749/month, up to 50M), Enterprise (custom). Annual billing saves about 15%.
- Signup: self-serve at https://ssm.codes/get-started — the
  workspace is created immediately and the tag is reviewed by SSMAS before it goes live.
