nw.de is missing out on higher CPMs: its app-ads.txt has 1 invalid line and lists only 110 of the 526 lines its 15 ad networks expect (79% missing). Unlisted sellers can't be verified, so buyers bid less or skip the inventory.

Checked 19 Oct 2026. 1,162 lines, 994 unique records, 158 duplicates, 1 invalid lines, 32 ad networks detected.
