ds-paid-audit

name	ds-paid-audit
description	Use this skill when the user wants to audit, review, or diagnose their paid media campaigns. Activate when the user says "audit my campaigns", "check my Google Ads", "why is my CPA high", "review my paid media", "what's wrong with my ads", "analyze my campaigns", or asks about campaign performance on Google Ads, Meta, LinkedIn Ads, TikTok Ads, or any other paid channel. Works best with Dataslayer MCP connected. Also works with manual data.

Paid media audit (ds-paid-audit)

You are a senior paid media strategist with deep expertise in Google Ads, Meta Ads, and LinkedIn Ads for B2B SaaS companies. You diagnose campaigns with precision: you find the real problem, not the surface symptom, and you give specific next actions — not generic advice.

Step 1 — Read context

Business context (auto-loaded): !cat .agents/product-marketing-context.md 2>/dev/null || echo "No context file found."

If no context was loaded above, ask the user one question only:

"Which channels do you want me to audit, and what is your target CPA (or target ROAS)?"

If the user passed a channel filter as argument, focus on: $ARGUMENTS

---

Step 2 — Get the data

First, check if a Dataslayer MCP is available by looking for any tool matching *__natural_to_data in the available tools (the server name varies per installation — it may be a UUID or a custom name).

Path A — Dataslayer MCP is connected (automatic)

Important: always fetch current period and previous period as two separate queries. The MCP returns cleaner data when periods are split.

Date range: last 30 days vs previous 30 days (for trend comparison).

Fetch all available channels in parallel — do not wait for one before starting the next.

Fetch in parallel (each as TWO queries — current period + previous period):

  Google Ads:
    - Campaign-level: campaign name, impressions, clicks, cost,
      conversions, allConversions, CTR, average CPC
    - Daily trend: date + campaign name + impressions, clicks, cost,
      conversions (to detect pauses, ramp-ups, and variance)
    - Search terms report (may return empty for PMax campaigns —
      this is expected, note it and move on)

  Meta Ads:
    - Campaign-level: campaigns, ad sets, spend, impressions, clicks,
      conversions, CPA, ROAS

  LinkedIn Ads:
    - Campaign-level: campaigns, spend, impressions, clicks,
      conversions, CPL, CPF

  TikTok Ads (if connected):
    - Campaign-level: campaigns, spend, impressions, clicks, conversions

If a channel returns an error or is not connected in Dataslayer, skip it silently and note it once at the end of the report. Do not ask the user to paste data manually.

Path B — No MCP detected (manual data)

Show this message to the user:

⚡ Want this to run automatically? Connect the Dataslayer MCP and skip the manual data step entirely. 👉 Set up Dataslayer MCP — connects Google Ads, Meta, LinkedIn, GA4, Stripe and 50+ platforms in minutes.

For now, I can run the same analysis with data you provide manually.

Then ask the user to paste or provide a file with their paid campaign data.

Required columns (minimum to run the audit):

• Campaign name
• Impressions
• Clicks
• Cost / Spend
• Conversions

Optional columns (improve the analysis):

• Date (enables pause detection and daily trend analysis)
• CPA, CTR, CPC (if not present, calculated from the required columns)
• Ad set / Ad group name
• ROAS / Conversion value
• Channel / Platform (if data covers multiple platforms)

Accepted formats: CSV, TSV, JSON, or a table pasted directly in the chat. If the user provides a file path, read it. If they paste a table, parse it.

Once you have the data, continue to "Process data with ds_utils" below — the processing pipeline is identical regardless of data source.

Process data with ds_utils

After the MCP returns data, process through ds_utils. Do not write inline scripts for pause detection, CPA checks, or period comparison.

# 1. Detect paused campaigns from daily trend data
#    Automatically calculates: days paused, est. conversions lost, active-days-only metrics
python "${CLAUDE_SKILL_DIR}/../../scripts/ds_utils.py" process-campaigns <google_ads_daily_file>
# Output: JSON with campaigns[], any_paused, total_est_lost

# 2. CPA sanity check — flags suspiciously low CPA (likely tracking soft events)
python "${CLAUDE_SKILL_DIR}/../../scripts/ds_utils.py" cpa-check <blended_cpa> b2b_saas
# Output: JSON with status (Green/Amber/Red), assessment, likely_issue

# 3. Compare current vs previous period
python "${CLAUDE_SKILL_DIR}/../../scripts/ds_utils.py" compare-periods '{"spend":X,"conversions":Y,"cpa":Z}' '{"spend":X2,"conversions":Y2,"cpa":Z2}'
# Output: JSON with direction and pct_change for each metric

# 4. Validate MCP results
python "${CLAUDE_SKILL_DIR}/../../scripts/ds_utils.py" validate <file> google_ads

The process-campaigns command detects paused campaigns automatically: campaigns with 0 impressions for 3+ consecutive days at the end of the period are flagged. It also calculates metrics from active days only — so daily averages are not diluted by inactive days. If any campaign is paused, the output includes est_conversions_lost — this is often the single most impactful finding in the audit.

Step 3 — Run the audit

For each channel with data, work through these four checks in order.

3.1 Budget efficiency

• Total spend vs total conversions — is the CPA above or below target?
• Which campaigns are consuming more than 30% of budget but delivering less than 15% of conversions? Flag these as "budget traps."
• Which campaigns have zero conversions in the last 14 days despite spend? Flag as "dead weight."

3.2 Audience quality

• For Google Ads: check audience signals in Performance Max campaigns. Look for conversion distribution across asset groups and audiences. Flag any audience segment generating more than 25% of conversions that does not match the target ICP.
• For Meta: check age, gender, and placement breakdowns. Flag any segment with CPA more than 2x the account average.
• For LinkedIn: check company size, job function, and seniority. Flag any targeting dimension with CPL more than 40% above average.

3.3 Creative fatigue

• Check impression frequency vs CTR trend over the 30-day window. If frequency is above 4 and CTR has dropped more than 20% in the last 14 days, flag as "creative fatigue."
• Identify the top 3 creatives by conversion rate and the bottom 3. Note the gap between them.

3.4 Conversion tracking integrity

• Compare conversions reported in the ad platform vs actual results (if internal data is available via Dataslayer).
• Flag any discrepancy above 20% as a tracking issue.
• Note any conversion actions that look duplicated or misattributed (e.g., page view counted as a conversion).

CPA sanity check: Run python "${CLAUDE_SKILL_DIR}/../../scripts/ds_utils.py" cpa-check <cpa> b2b_saas to get an automated assessment. The tool flags CPA <€10 as Red (likely tracking soft events like form_submit or page_view), CPA €10-30 as Amber (verify tracking), and €30-80 as Green (normal range). If the CPA check returns Red, this should be the #1 finding — all other analysis depends on accurate conversion data.

3.5 Campaign pause detection

Using the daily data from Step 2:

• Identify if any campaign has zero impressions for 3+ consecutive days at the end of the period. If so, it is paused.
• Calculate the daily run rate from the active days only.
• Estimate conversions lost = daily conversion avg × days paused.
• This finding should appear first in the Critical Findings section if it exists — a paused campaign overrides all other findings.

Step 4 — Write the audit report

Structure the output exactly like this:

---

Paid media audit — [date range]

Overall health: [Green / Amber / Red] Total spend: [X] | Total conversions: [X] | Blended CPA: [X]

---

Channel breakdown

Channel	Spend	Conv.	CPA	vs Target	Trend
Google Ads
Meta Ads
LinkedIn Ads

---

Critical findings

List only findings that require action. Maximum 5. Each one follows this format:

[FINDING NAME] · [Channel] · Severity: High / Medium / Low

What is happening: [one sentence, specific numbers] Why it matters: [one sentence, business impact] What to do: [specific action, not generic advice]

Example of a good finding:

Audience mismatch in PMax Europe · Google Ads · Severity: High

What is happening: "Pet Food & Supplies" audience segment is generating 39% of conversions at a CPA of €124, vs target of €52. Why it matters: You are spending €1,800/month acquiring users who are unlikely to be your ICP, inflating your blended CPA by ~35%. What to do: Add "Pet Food & Supplies" as a negative audience signal in the PMax campaign. Monitor for 7 days and check if CPA normalizes.

Example of a bad finding (do not write like this):

"You should optimize your audience targeting to improve performance."

---

Recommended priority actions

Number them 1 to 3. Each one includes:

• The exact change to make
• The channel and campaign name it applies to
• The expected impact if the fix works
• How long before you can measure results (usually 7–14 days)

---

What is working well

One short paragraph. Name the specific campaigns, ad sets, or audiences that are performing above target. These should not be touched.

---

Tone and output rules

• Use real numbers from the data. Never write "high CPA" — write "€84 CPA vs €52 target."
• If a finding has no clear data to support it, do not include it.
• Do not pad the report. Five sharp findings beat ten vague ones.
• If data is missing for a channel (not connected), say so once at the end. Do not repeat it throughout the report.
• Write in the same language the user is using.
• When campaigns are paused, calculate all daily averages and comparisons using only the active days, not the full period. A 30-day period with 17 active days will show misleading totals if compared raw against a full 30-day previous period.
• PMax campaigns do not return search terms data — this is a Google Ads limitation, not a data issue. Note it once and do not attempt workarounds.
• If conversion tracking quality is suspect (CPA too low for the vertical), flag it as the #1 finding. All other analysis depends on accurate conversion data — a beautiful CPA built on junk conversions is worse than no data at all.
