The Largest Creator Boost in March Never Touched a Profile
March set this year's highs: 1.2M partnership ads, 9.6B in adjusted reach, up to €100M in modeled spend. The single biggest boost in all of it ran fully dark.
March was the biggest month for boosted partnerships in the EU so far this year, on every axis the Paid Partnership Report measures: 1.2M ads, 9.6B in adjusted reach, and a modeled €67–100M in spend.
One dark boost reached 19.9M people
The largest single creator boost we measured in March – and the largest this year – was a Shopify partnership with a 743k-follower creator. It reached an estimated 19.9M people on a modeled €80–120k. On the creator's profile there is no post to find; the entire campaign ran as a dark ad.
For scale: the biggest public boost of the month reached 9.1M. The biggest activity keeps happening behind the wall.

Dark reach grew to 6.5B impressions
68% of March's boosted-partnership reach was dark – 6.5B impressions with no public trace, more than any other month this quarter. More brands are labeling their boosts, and the dark layer is growing anyway; the whole market is simply bigger.
3,200 brands, 15,500 creators
3,247 brands ran at least one boosted partnership in March, the second straight monthly increase (2,350 in January, 2,722 in February). 15,500 creators fronted at least one boost.
Temu alone still delivered over half of all EU boosted-partnership reach; the story of everyone else keeps growing underneath it.
Country spotlight: France
France took 1.3B boosted-partnership impressions in March, and Temu's pages delivered about two-thirds of them. 431 other brands shared what was left.
The biggest public boost in the country came from the other end of the market: Apple partnered with one of francophone pop's biggest stars, reaching 5.2M people on a modeled €15–22k.
