Meta announced that ad prices will rise in six countries because it will no longer absorb local digital service taxes. The increases range from 2 to 5 percent and apply based on where ads are delivered, not only where the advertiser is based. That detail matters for arbitrage teams running cross-border traffic, because even if the ad account sits elsewhere, the campaign economics still change at the GEO level.  

For affiliate buyers, this is not just “platform news.” It hits campaign math directly. Margins get tighter on already expensive geos, break-even bids move, and previously acceptable funnels can slip below target ROI without any visible creative or offer change. In practice, teams running Meta traffic into thin-margin verticals will need to recheck bid ceilings, EPC floors, and approved CPA ranges market by market.
