Task Packs

Marketing Foundation

Compact two-skill starter: clarify positioning and choose a lead magnet. Use Marketing Launch for the broader eight-skill go-to-market workflow.

Marketing Launch

Build an evidence-led marketing plan from ICP and competition through positioning, campaigns, growth and measurement.

Agent Audit Essentials

Diagnose architecture and context, plan agent-team responsibilities, then organize project context and session handoffs. Memory and cost-runtime reviews remain outside this pack.

Conversion and Activation Review

Review the journey from landing page and lead capture through registration, first value and transparent upgrades.

Campaign Content and Brand Review

Plan a campaign, draft its channel content and review the work against actual brand guidance.

Content and Launch Planning

Prioritize an editorial roadmap and plan how to launch and distribute it across suitable channels.

Customer, Market and Community Research

Understand customer needs, compare competitors and plan a community around real member value.

Lead Magnet to Lifecycle Nurture

Choose a relevant lead magnet, then draft a permission-based nurture journey with entry, suppression and exit rules.

API Contract and Observability

Define the API contract, then plan how to observe its latency, failures and retries. Guidance and checklist; no production changes.

Data Analysis Foundation

Profile a dataset, choose and interpret statistical methods, then validate calculations and conclusions before sharing.

# Google Ads Guardrails

**READ BEFORE GENERATING ANY RECOMMENDATION.**

## Budget Reallocation Prohibition

You CANNOT allocate, shift, increase, reduce, or "optimize" budget for: keywords, search terms, match types, devices (unless bid adjustments in Search), locations (unless bid adjustments or exclusions), audiences (unless bid modifiers), asset groups (PMax has no asset-group budgets).

**Before writing ANY recommendation, ask:** Does this imply moving money between keywords, queries, products, devices, audiences, or asset groups? If YES → rewrite using valid controls below.

## Valid Budget Controls

| Campaign Type | Valid Controls |
|--------------|---------------|
| Search / Shopping | Campaign daily budget, bid strategy targets (tCPA/tROAS/max CPC), pause/enable campaigns or ad groups |
| Performance Max | Campaign daily budget, bid strategy targets (tCPA/tROAS), pause asset groups or campaign |

If a recommendation does not map to one of these controls, it is not actionable.

## Mandatory Rewrites

❌ "Shift budget from keyword A to keyword B"
✅ "Pause keyword A. Increase campaign daily budget by 10–20% to allow keyword B more eligible demand."

❌ "Allocate more to [breakdown: placement/device/demographic/product/asset group]"
✅ "Create a new campaign targeting [dimension] with its own budget, OR use bid adjustments/exclusions."

**Rule**: Any recommendation implying budget movement between sub-campaign entities must be rewritten to use campaign budget, bid targets, pause/enable, or structural separation.

## Metric Selection

First infer conversion type:
- **Ecommerce**: Use ROAS, conversion value, cost per purchase. Never use CPA alone for revenue decisions.
- **Lead gen**: Use CPA, cost per lead. Never use ROAS unless offline revenue is imported.
- **Unclear**: ASK the user. Do not assume.

## Scaling Limits

- Max budget increase: **20% at a time**
- Never scale if: CPA > target, ROAS < target, or query/search term hygiene not done
- Never scale based on: Impression Share alone, CPC alone, or early data (< 7 days)
- Frame scaling as: "Incremental test with downside risk"

## Learning & Stability

- Do not stack changes (budget + bids + structure simultaneously)
- Do not judge performance on: < 30 conversions (Search), < 50 conversions (PMax/Shopping)
- Avoid changes that reset learning unless absolutely required

## Immediate STOP Triggers

Halt any recommendation that attempts:
- "Scale keywords / products / asset groups"
- "Reallocate spend between queries"
- "Optimize placements in PMax"
- "Increase bids and budget at the same time"
- "Scale > 20% in one step"
- "Fix low IS by increasing budget blindly"

## Required Diagnostics Before Any Action

Before any scale/pause/restructure suggestion, check:
1. Search term quality (Q4/Q5 presence)
2. CPA/ROAS vs target
3. IS Lost (Rank vs Budget breakdown)
4. CPC trend direction
5. Conversion volume sufficiency
6. Bidding strategy compatibility

If diagnostics are incomplete → say **insufficient data**, do not recommend.

When to use

Check Google Ads recommendations against valid budget controls, metric choice and source scaling rules.

What you get

The complete original GoMarble guidance, with source attribution and declared limits.

How it works

Clarify scope, use available evidence, and apply the relevant source workflow within actual user authorization.

Requirements

Campaign type, actual controls, conversion type, targets and supporting account evidence.

Delivery and review notes

The source thresholds and 20% scaling rule are heuristics, not performance guarantees; validate current platform controls. GoMarble connectors, referenced sibling skills and runtime dependencies are not bundled or installed by M11. Brief obvious-danger screening only; no functional test or comprehensive safety certification. Loading this text authorizes no external calls, account mutations or ad spend.

Starting prompt

Use Google Ads Optimization Guardrails for [TASK]. Clarify Campaign type, actual controls, conversion type, targets and supporting account evidence. Separate observed evidence from heuristics and recommendations. Check actual connector availability and approval semantics before any external action.

Not for

Claiming installed GoMarble tools, proven campaign outcomes or authorization to launch ads merely from loading this source.

What M11 added

German routing and explicit scope. Original attribution: GoMarble. The source thresholds and 20% scaling rule are heuristics, not performance guarantees; validate current platform controls. GoMarble connectors, referenced sibling skills and runtime dependencies are not bundled or installed by M11. Brief obvious-danger screening only; no functional test or comprehensive safety certification. Loading this text authorizes no external calls, account mutations or ad spend.
