line.me app-ads.txt check

line.me is missing out on higher CPMs: its app-ads.txt has 2 invalid lines and lists only 3,270 of the 4,771 lines its 28 ad networks expect (31% missing). Unlisted sellers can't be verified, so buyers bid less or skip the inventory.

Checked 19 Oct 2026. 4,287 lines, 3,833 unique records, 170 duplicates, 2 invalid lines, 43 ad networks detected.
