LinkedIn Ads CPA

LinkedIn publishes floors, not rates: a $10 minimum daily budget and a $2 minimum bid for CPC and CPM campaigns. No CPA or CPL benchmark exists first-party. For most B2B buyers the honest LinkedIn metric is cost per lead; acquisitions close months later, offline.

Auction-based; objective-based pricing (CPC/CPM/CPS). Published floors: $10 minimum daily budget and $2 minimum bid for CPC/CPM campaigns. No published CPA/CPL benchmark first-party.▸LinkedIn · checked 2026 Auction pricing with objective-based billing; verified 2026-08-01. The floors matter practically: minimum bids in a professional-targeting auction set a high per-click cost basis, which is why LinkedIn CPLs run multiples of search CPLs for the same company.

A B2B deal signed in Q3 rarely maps cleanly to the Q1 campaign that sourced it. Platform-attributed "conversions" on LinkedIn are form fills and demo requests: leads. Report CPL from the platform, then translate to pipeline CPA with your own close rate: effective CPA = CPL ÷ lead-to-close rate. A $180 CPL closing at 15% is a $1,200 acquisition; whether that works is a ceiling question about contract value, not an ad-platform question. The multiple table is on CPA vs CPL.

• Judge lead quality per campaign, not platform-wide: title and company-size filters are the product; loose targeting buys cheap leads that never close.
• Compare against search honestly: LinkedIn reaches people not searching. The fair test is cost per closed deal by source over two quarters, walked through on LinkedIn vs Google.
• SaaS context and CAC-payback framing: SaaS benchmarks and CPA vs CAC.
