FAQ

How is Didomi scored?

Didomi scores 3.7 out of 5 in Benchmark Grid's independent Best Consent Management Platforms (CMPs) for Publishers benchmark. The overall figure blends capability (45%), publisher fit (40%) and cost of ownership (15%). Capability is itself a weighted average of 10 criteria; the heaviest are iab tcf v2.2 compliance & ad-tech signal propagation (14%), consent capture ux & opt-in rate optimization (12%) and google consent mode v2 integration (12%). Vendors cannot pay for a score.

What size publisher is Didomi built for?

Didomi is built for mid-market publishers and 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 Didomi cost?

Our cost-of-ownership score is 2.5/5, 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 Didomi?

We have evidenced 21 publishers running Didomi. 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 Didomi 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.
