Platform-dependent. Google Search Ads: 5-9% average; over 10% excellent. Meta Ads: 0.9-1.5%; over 2% excellent. LinkedIn: 0.5-0.8%; over 1% excellent. TikTok: 1-3%; over 4% excellent. Display Network: 0.05-0.5%. Don't expect Google Search CTRs on Meta — search captures intent (user typed a query); social captures attention (user is scrolling). Different mechanisms, different baselines.

Three levers: (1) Improve CTR — better creative, more relevant copy, A/B test. (2) Improve CVR — landing page optimization, clearer CTA, social proof, better offer. (3) Lower CPC — improve quality score (Google), narrow targeting (Meta), bid strategy adjustments. The biggest gains usually come from CVR improvements — even small changes (3% to 4% CVR = 33% lower CPA) compound throughout the funnel. Don't fixate on CPC alone.

What's CPM useful for?

Awareness campaigns where impressions matter (brand-building, product launches). Programmatic display buying. YouTube and connected TV. Comparing reach efficiency across channels. For performance marketing (lead gen, e-commerce), CPA matters more than CPM — you don't care about cheap impressions if they don't convert. Use CPM to evaluate awareness; CPA to evaluate performance.

Why is LinkedIn so expensive?

Premium audience. LinkedIn users are often high-income B2B decision-makers; advertisers pay correspondingly more. Average LinkedIn CPM $30-50 vs Meta $7-15 — 3-5× higher. But conversion value is also higher (B2B leads often worth $500-5000 vs B2C $50-200). The math works for high-LTV businesses; doesn't for low-ticket consumer products. LinkedIn is rarely cost-effective for B2C.

Search vs Social ad strategy?

Search Ads (Google, Bing): user typed a query — high intent, ready to convert. Highest CVR (4-10%); highest CPC ($1-50); often best ROI for established demand. Social Ads (Meta, TikTok, LinkedIn): user is scrolling — interruption, lower intent. Lower CVR (1-3%); lower CPC ($0.50-3); better for awareness, demand creation, retargeting. Most successful brands run both: search to capture demand, social to create demand.

What's a benchmark CPA?

Wildly industry-dependent. E-commerce average: $15-50 CPA. SaaS B2B: $200-2000 CPA. Mortgage / insurance leads: $50-500. Mobile app installs: $2-15 CPA in most categories. Don't use generic CPA benchmarks; look up your specific industry. Better question: what's your maximum acceptable CPA based on customer LTV? Generally CPA should be 20-30% of first-year LTV for healthy unit economics; 30-50% for mature businesses with high retention.

What it does

Digital advertising metrics are layered: impressions (how many times an ad was shown) → clicks (how many of those impressions resulted in a user click) → conversions (how many of those clicks resulted in a desired action like signup, purchase, or download). Each transition has its own efficiency metric: CPM (Cost Per Mille — cost per 1000 impressions, the headline rate for awareness campaigns and programmatic buying), CTR (Click-Through Rate — clicks/impressions, measures ad appeal), CPC (Cost Per Click — spend/clicks, the dominant pricing model on Google Ads and Microsoft Ads), CVR (Conversion Rate — conversions/clicks, measures landing page and offer effectiveness), CPA (Cost Per Acquisition — spend/conversions, the headline efficiency metric for performance marketing). Understanding the full funnel matters: a low CPC with poor CVR can produce worse CPA than a high CPC with strong CVR.

The converter takes any two metrics (typically spend + impressions, or spend + clicks, or impressions + clicks + conversions) and computes the rest. Plus shows the full funnel visual: 100% of spend → X impressions → Y clicks (CTR%) → Z conversions (CVR%) → CPA per conversion. Helpful for: planning ad budgets backwards from desired conversion volume; comparing channel performance (Google Ads vs Meta vs LinkedIn vs TikTok); identifying funnel bottlenecks (low CTR = ad creative problem; low CVR = landing page problem; high CPA despite good CTR/CVR = price too high or targeting wrong audience).

Industry benchmarks worth knowing (2024- 2025 data): Google Search Ads: CTR 5-9% average, CPC $1-5 most categories ($20-50 insurance/legal), CVR 4-7%, CPA varies wildly by industry. Meta (Facebook + Instagram) Ads: CTR 0.9-1.5% average, CPM $7-15 in US, CPC $0.50-2.50. LinkedIn Ads: CTR 0.5-0.8% (lowest of major platforms), CPC $5-15, CPM $30-50 (premium audience). TikTok Ads: CTR 1-3%, CPC $1-3, CPM $5-12. Display network (Google/programmatic): CTR 0.05-0.5% (much lower than search), CPM $1-3, CPC $0.30-1.50. Search ads convert best (high intent); display is for awareness; social mid-funnel. Don't compare CPM/CPC across platforms without context — different audiences, different intent levels.

Enter any two known metrics: spend, impressions, clicks, conversions.
Read calculated CPM, CTR, CPC, CVR, CPA.
Compare to platform benchmarks for your industry and audience.
Identify the weakest funnel stage (low CTR = creative; low CVR = landing page; high CPA = pricing/targeting).
Use back-calculations to plan budget: target X conversions / target CPA = required spend.

When to use this tool

Setting up a new ad campaign — backing into budget from conversion targets.
Comparing channel performance across Google, Meta, LinkedIn, TikTok.
Diagnosing underperforming campaigns — which funnel stage is the bottleneck.
Quarterly marketing review — calculating efficiency metrics from raw spend data.
Forecasting — “if we double spend, what conversion volume should we expect?”

When not to use it

Brand campaigns where conversions aren't the goal — different metric set (reach, frequency, brand lift).
Multi-touch attribution analysis — needs more sophisticated tools (Northbeam, Triple Whale, Hyros).
Influencer marketing pricing — different model (CPM by follower count, plus engagement metrics).
Affiliate marketing — uses different fee structures (commission %, CPL, CPS).

Common use cases

Verifying a number or output before passing it on
Quick conversion during a typical workday
Pre-decision sanity-check on inputs and outputs
Educational use — demonstrating the underlying concept
