Blog/Paid Media Strategy
Paid media KPIs that actually matter — stop tracking vanity metrics.
A good paid media report has 5–7 metrics with a clear action for each: CPL and CPA for efficiency, ROAS for eCommerce profitability, CVR for funnel health, Impression Share to spot budget waste on Google, and Frequency to spot audience exhaustion on Meta. CTR is a diagnostic metric, not a success metric. Most reports contain 30+ metrics and no clear story. The result: executives feel informed and have no idea what to change.

“I see agency reports with 40 metrics and no clear story. The client is impressed and has no idea what to do next. A good report has one conclusion per metric: this is working, this isn't, here's why.”

The KPI hierarchy
Three tiers of metrics — and what each tier tells you.
Business KPIs — are we profitable?
Revenue from paid media, total leads generated, cost per acquisition (CPA), customer acquisition cost (CAC), and return on ad spend (ROAS). These are the metrics that determine whether paid media is worth running at all. Review monthly. They should drive go/no-go and budget increase decisions.
Channel KPIs — is each channel performing?
CPL by channel, ROAS by channel, CVR by campaign, CPA by audience segment. These tell you which channels and campaigns within your mix are working and which need reallocation. Review weekly with a 30-day trend lens. Use these to allocate budget between channels and campaigns.
Diagnostic metrics — why is performance changing?
CTR, Quality Score (Google), Frequency (Meta), Impression Share, search term relevance, audience overlap. These don't measure success — they diagnose the cause of success or failure. High CTR with low CVR = landing page problem. Rising Frequency + falling CVR = audience exhaustion. Falling Impression Share = budget or bid problem. These are investigation tools, not headline metrics.
Vanity metrics to stop prioritising
Impressions
Volume without quality tells you nothing. 10M impressions at 0% CVR is waste.
Reach
A downstream metric of impressions. Same limitation applies.
Engagement rate
Likes and comments don't buy products. Brand awareness KPI at best.
CTR alone
High CTR on a poorly converting landing page is just expensive traffic.
Reporting cadence
Search Terms report (add negatives), Frequency check (creative refresh if >4), budget pacing vs plan, CPA/CPL 7-day trend.
Channel-level ROAS and CPL vs target, creative performance ranking, audience fatigue review, budget reallocation recommendation.
CAC:LTV ratio review, channel mix evaluation, testing roadmap for next quarter, strategic budget increase decisions.
KPI reference
| Metric | What it measures | Good benchmark | Action threshold |
|---|---|---|---|
| CPL (Cost per Lead) | Ad spend ÷ leads generated | Varies by industry — benchmark against deal value | CPL exceeds 20% of average deal value |
| ROAS (Return on Ad Spend) | Revenue ÷ ad spend | 3–5x for most eCommerce (margin-dependent) | Below break-even ROAS (1 ÷ margin) |
| CVR (Conversion Rate) | Conversions ÷ clicks (or sessions) | 2–4% eCommerce, 3–8% lead gen LP | Below 1% — landing page or audience problem |
| CPA (Cost per Acquisition) | Ad spend ÷ conversions | Below maximum allowable CPA (LTV ÷ target ratio) | Above max allowable CPA for 7+ days |
| Impression Share (Google) | Impressions received vs available | 90%+ branded, 50–70% non-brand | Lost to budget IS >20% — increase budget |
| Frequency (Meta) | Avg times same user saw your ad | 1–3 for cold audiences | Above 4 — audience exhaustion, refresh creative |
| CTR (Click-Through Rate) | Clicks ÷ impressions | 2–5% Search, 0.5–2% Display/Social | High CTR + low CVR = LP problem, not ad problem |

FAQ
Common questions about paid media KPIs.
What is a good ROAS for paid media?+
There is no universal good ROAS — it depends entirely on your margins. A 3x ROAS means $3 revenue per $1 spent. If your product margin is 70%, 3x ROAS is profitable. If your margin is 30%, you need 4–5x ROAS to break even after ad spend. The correct target is: 1 ÷ (margin - overhead percentage). For a product with 40% gross margin and 10% overhead, your break-even ROAS is 1 ÷ 0.30 = 3.3x. Target above that for profitability.
What is a good cost per lead (CPL) benchmark?+
CPL benchmarks vary enormously by industry and channel. B2B SaaS on LinkedIn: $50–$300 per lead. B2B services on Google Search: $30–$150. Consumer services on Meta: $15–$60. eCommerce lead gen (email capture): $1–$5. The right CPL is determined by your close rate and deal value: if you close 10% of leads at $5,000 average deal, a $200 CPL gives you a 25x ROI on marketing spend. Always benchmark CPL against qualified CPL — not all leads are equal.
What is Impression Share in Google Ads and why does it matter?+
Impression Share (IS) is the percentage of impressions your ads received vs the total impressions available for your keywords. If your IS is 40%, your ads showed in 40% of eligible auctions. Lost IS is split into 'lost to rank' (your ad rank wasn't high enough) and 'lost to budget' (your daily budget ran out before the day ended). For branded keywords, target 90%+ IS. For non-brand, 50–70% IS is often efficient. Lost to budget IS is the most actionable — it tells you exactly how much more revenue you could capture by increasing budget.
How often should I review paid media KPIs?+
Weekly reviews for diagnostic metrics: Search Terms (Google), Frequency (Meta), budget pacing. Monthly reviews for performance KPIs: CPL, ROAS, CPA trends, channel-level performance versus targets. Quarterly reviews for strategic decisions: budget reallocation, channel mix changes, CAC:LTV review. Don't make strategic changes based on daily data — too much noise. Weekly review with 7-day and 30-day trends is the right cadence for most accounts.
