Summary
Editor's update, October 2026: 19 Oct 2026 accuracy audit: take-rate claim removed and pricing set to free for publishers, empty copy written.
Authenticated Traffic Solution (ATS) and RampID graph with deep SSP/DSP integration; free for publishers, with costs carried on the buy side, but a notable implementation lift.
LiveRamp's Authenticated Traffic Solution (ATS) lets publishers recognise logged-in users and newsletter readers and make that inventory addressable through RampID, LiveRamp's people-based identifier. When a user authenticates, LiveRamp turns their data into a RampID envelope stored in a first-party cookie; SSPs read the envelope and re-encode it for each DSP in the bid request.
Its standout is cost and reach. ATS is free to publishers, with costs built into the buy side, the basic integration is a JavaScript snippet, and LiveRamp works with Prebid.js and header-bidding partners to pass the ID. Publishers such as Prisma Media use it to offer more addressable inventory to advertisers.
The limitations are implementation and proof. Publishers must submit domains for review and deploy ATS.js across all pages, value depends on the share of authenticated users, and LiveRamp publishes no match-rate or uplift figures for ATS.

Capability is itself a weighted average of 10 criteria; the heaviest are match rate & cross-domain reach (16%), privacy & consent-native design (14%) and prebid/ssp integration & signal distribution (12%). Vendors cannot pay for a score.
What size publisher is LiveRamp RampID built for?
LiveRamp RampID is built for enterprise publishers. That is the vendor's own stated target, and it is one of the inputs to our publisher-fit score — a platform that suits a national newsroom often carries more operational load than a small one can absorb.
What does LiveRamp RampID cost?
ATS is free for publishers; costs are built into the buy side. Our cost-of-ownership score is 3.4/5, which weighs pricing transparency, entry cost, implementation cost, hidden-fee risk and ongoing cost. Ask the vendor for a written first-year figure that includes implementation before you commit.
Who uses LiveRamp RampID?
We have evidenced 24 publishers running LiveRamp RampID. Adoptions are detected from site code, ads.txt records and published case studies rather than taken from the vendor's own customer list, and each one is listed on this page.
Can LiveRamp RampID pay for a better score?
No. Scores come from our editorial review of the product's documentation, demos and public evidence. A vendor can claim this listing or request a re-review, but nothing they buy changes a score or a position.
