Yes — verifying a business account sometimes unlocks higher spending limits and smoother ad delivery, which might indirectly lower your effective cost. But verification doesn’t guarantee lower costs per click or impression — that mainly depends on ad quality, targeting, competition.
To verify: go to Meta Business Settings → Business Info → Start Verification, then submit documents (business license, tax ID, proof of address, etc.). Facebook will review and either approve or ask for clarifications — process may take days.
After verification, monitor whether your ad costs drop — optimize creatives, targeting, relevance to get real gains.
