Ask Claude about your Google Ads data
Load Google Ads into your data warehouse first, link campaign cost, clicks and conversions to web analytics and deals with SQL keys, then ask Claude in plain words. The answers come from your governed Data Marts, not from the ad account.

ClaudeDateCostClicksDaily 09:00An ad's click-through rate drops, and you can't tell whether you're losing buyers or only casual clickers.
Paste this into your AI assistant. It sets up a governed Google Ads Data Mart in OWOX Data Marts and connects Claude through the OWOX MCP server, so it compares weeks from your own ad data.
The prompt
Read https://www.owox.com/ai-agent-setup.md and follow it to set up OWOX Data Marts for me, starting from /connectors/google-ads-connector-to-claude.md. The task: answer in Claude from my Google Ads Data Mart: which running ads lost click-through rate against the week before, and whether their conversion value held. Tag the links you give me with utm_campaign=ai-task and utm_term=data-foundation. Use what you know about my context and goals

Why Claude needs your data warehouse, not the Google Ads account
Pointed at the Google Ads account alone, Claude sees one platform's own figures. The account does not show which campaign led to a deal, because ad spend, website visits and CRM deals live in different systems. Joining them reliably, at scale and business-ready is the job of a warehouse, so Claude reads the answers from there.
- Google Ads reports clicks and the conversions it counted, not what the customer was worth
- The data analyst links Google Ads spend, web analytics and CRM deals by SQL keys and controls the result
- Claude reads governed Data Marts, so every answer traces back to analyst-written SQL

Data warehouseJoined by idStep 1: Load Google Ads into your data warehouse first
Create a Data Mart with Google Ads as the source and choose where the data lands. It works with any popular data warehouse.
- Nine endpoints and 166 fields to choose from, each endpoint in its own table
- Open the Google Ads connector for your data warehouse below

In your data warehouse the model merges Google Ads with your other ad platforms, then joins web analytics sessions by a campaign key. Pick an industry to see the shape of its model.
- Ad spend from Google Ads, Microsoft Ads and Facebook Ads sits in one table
- Sessions and deals join by SQL keys, not VLOOKUP and gut feeling
- The measures, such as platform_cpa, are defined once

Add the OWOX MCP server in Claude under Settings > Connectors, then choose the Data Marts it may see. Claude gets only what you expose, never raw database access.
- Authorize specific Data Marts, not your whole data warehouse
- Publish the Data Marts you want Claude to answer from, such as Google Ads Campaigns Stats, Keywords Stats or Geo Stats

Ask in plain words. Claude finds the right Data Mart and runs analyst-defined SQL against it, so the answer is built from your data warehouse.
- The answer is built by get_relevant_data_marts_by_prompt and query_data_mart
- Ask by campaign, keyword or country: each is a separate Google Ads table the answer can read
- platform_roas and platform_cpa are what each platform claims; Sessions and Orders in the same model give the store's own count to set against them

In one click, export the answer or its source data to Google Sheets, CSV or XLS.
- The export is the same Data Mart the assistant read, so the file and the chat agree
- Optional: ask in chat first, export only what you need

Why OWOX for Google Ads in Claude
Google's BigQuery Data Transfer Service copies Google Ads reports once a day, into report tables named per Customer ID, and only into BigQuery. OWOX loads the same data on your schedule, into any popular data warehouse, in tables made to be joined with the rest of your marketing data, so Claude can answer from all of it.
- You own the data. It lands in your own data warehouse, in tables you control.
- Google Ads in any data warehouse. The Data Transfer Service serves BigQuery only. OWOX loads Google Ads into BigQuery, Snowflake, Redshift, Athena or Databricks alike, so blended ad spend stays one model.
- Campaigns, ad groups, keywords and geo. Campaigns Stats, Ad Groups Stats, Keywords Stats and Geo Stats are separate tables, ready to join to sessions and deals.
- Zero hallucinations. Claude queries governed Data Marts with analyst-written SQL, so every number traces back to the query behind it.
- Maintained for you. No scripts to fix when Google changes its API.
