# GAQL Prompt Library: 50 Google Ads Queries to Paste Into Claude

**Key takeaways**

- **No GAQL required** — the assistant translates plain-English prompts into queries.
- **50 prompts across 8 jobs** — waste, keywords, budget, creative, audiences, conversions, competition, reporting.
- **Add a window and a threshold** to each prompt for sharper answers.
- **Read-only is enough** — every prompt here is analytical; changes need a separate write server.
- **The prompt library is the moat** — it's what separates a decent Google Ads agent from an excellent one.

The biggest determinant of how good an AI-assisted Google Ads workflow is turns out not to be the model or the server — it's the prompt library. A reusable set of well-scoped questions is what turns a novelty into a daily tool. Below is a working **GAQL prompt library** you can lift directly. Each prompt assumes an MCP connection to your account (see the [Google Ads MCP resource](https://www.growthspreeofficial.com/resources/google-ads-mcp) and [Ai Augmented Google Ads Workflow B2B SaaS B2B 2026 12 Step Operator Playbook](https://www.growthspreeofficial.com/blogs/ai-augmented-google-ads-workflow-b2b-saas-b2b-2026-12-step-operator-playbook)); the assistant handles the GAQL.

## How to use this GAQL prompt library

Paste a prompt, and optionally add a **time window** ("last 14 days") and a **threshold** ("CPL over $150"). The assistant fills in the GAQL dimensions and metrics, runs the query through your Google Ads MCP server, and returns the answer. Keep the connection read-only so the assistant can analyze freely without touching a live campaign.

4. Show top-of-page rate trend by campaign over 8 weeks.
5. Flag campaigns where absolute top impression share dropped this month.

> **Field note:** A practical habit is to run the Waste and Budget prompts on a schedule and route anomalies to a Slack channel for a human to action. Because a read-only Google Ads MCP server can analyze but not change anything, the assistant surfaces issues and a person makes every fix — the safest division of labor.

## How does this fit the rest of your stack?

These prompts run on a single connector, but the same assistant can reach further. Connect Google Ads alongside analytics and CRM using the [Ai Marketing Analytics MCP B2B](https://www.growthspreeofficial.com/blogs/ai-marketing-analytics-mcp-b2b), and reporting prompts can tie ad spend to pipeline. If you're still choosing a connector, [B2B SaaS Ad Testing Framework Google Ads Linkedin Ads 2026](https://www.growthspreeofficial.com/blogs/b2b-saas-ad-testing-framework-google-ads-linkedin-ads-2026) walks through the options, and the [MCP servers complete guide](https://www.growthspreeofficial.com/blogs/mcp-servers-b2b-saas-marketing-complete-guide) explains how the protocol works.

## Frequently asked questions

**Do I need to know GAQL to use these prompts?**
No. With a Google Ads MCP server connected, the assistant translates each plain-English prompt into the correct GAQL query, runs it, and returns the answer. The prompts are the interface; GAQL stays under the hood.

**Will these prompts change my Google Ads account?**
No, if you use a read-only server. Every prompt here is analytical — it reads data and reports. Making changes requires a separate write-enabled server with human approval.

**Can I schedule these GAQL prompts to run automatically?**
Yes. Many teams run the audit prompts on a schedule and route anomalies to Slack or email, with a human executing any fix.

**How do I get the most accurate answers from a GAQL prompt?**
Add a time window and a threshold to each prompt, and make sure conversion tracking is clean. The library is only as reliable as the underlying account data.

**What is GAQL?**
GAQL (Google Ads Query Language) is the query language for the Google Ads API. It's how reporting data is requested — and with an MCP server, the AI assistant writes it for you from a plain-English prompt.
