meetup.com app-ads.txt check

meetup.com is missing out on higher CPMs: its app-ads.txt lists only 332 of the 3,001 lines its 17 ad networks expect (89% missing). Unlisted sellers can't be verified, so buyers bid less or skip the inventory.

Checked 19 Oct 2026. 521 lines, 415 unique records, 30 duplicates, 0 invalid lines, 27 ad networks detected.
