Reddit reports lower CPA for advertisers with high optimization scores
Ad platforms · 20 Oct 2026 · By the Cofoundr team
Reddit released a campaign planner, a 0 to 100 optimization score and budget optimization in its Ads Manager. It says advertisers scoring 80 percent or higher saw 19.6 percent lower blended CPA than those with lower scores.
The key points
- Reddit supplied the figures from its own data, and the measurement details were not visible in the coverage.
- The result describes an association, not proof that raising the score lowers cost.
- Three of five budget optimization objectives are still in beta.
What it means for agencies
Platform-reported links between a score and cost are worth reading with care, because accounts with high scores may simply be better run. Meta's own optimization score works the same way, so treat any score as a prompt to check, not a result.
