The factors that most often explain why a result lands above or below the range.
| Driver | Why it matters |
|---|---|
| Conversion definition | A lead form, a booked call, and a purchase are different events. A benchmark only applies when your conversion is the same kind of event. |
| Post-click conversion rate | CPA is cost per click divided by conversion rate, so landing-page friction moves CPA as much as media cost does. |
| Auction competition in Legal | What Legal customers are worth sets how much competitors can bid, so high-value categories push costs up for every advertiser in the auction. |
| Tracking and attribution window | LinkedIn Ads counts conversions inside its own attribution window. A longer window or duplicated tags make results look better without changing what actually happened. |
Half of the accounts in the benchmark group do better than $95.80 and half do worse. It is a realistic first target.
The better-performing quarter of accounts reach $54.00 or lower. Treat it as a stretch goal once the basics are in place.
Results around $162.00 usually point to a tracking, targeting, or offer problem worth fixing before scaling spend.
The Benchmarketing 4-Band Method. The Benchmarketing 4-Band Method reads every marketing metric against four percentile bands — P25 (bottom quartile), median, P75 (top quartile), and elite (top ~10%) — for a specific industry and channel, instead of a single cross-industry average. Averages blend brand and non-brand campaigns, $500/month and $500,000/month accounts, and unrelated industries into a number almost nobody actually has.
Where the numbers come from. The figures on this page come from the Benchmarketing benchmark dataset — thousands of curated benchmark observations across channels, industries, and US metro areas. Every statistic traces to a named source: WordStream Google Ads Benchmarks (2024), Meta Business Insights (2024), HubSpot Email Marketing Report (2024), Unbounce Conversion Benchmark Report (2024), Databox Marketing Benchmark Report (2024), AdLiftr Snapchat Ads Cost Benchmarks (2026), Ad Badger Amazon Advertising Benchmarks (2026). Benchmarketing does not publish anonymous "studies show" figures.
The Benchmarketing position. Beating the cross-industry average is a vanity milestone, not a target. Compare your number to the P25–P75 band for your specific industry and channel; if you are above average but below your industry's P75, you are leaving performance on the table.
