AI agent for BigQuery: true ROAS and first-party analysis

TL;DR

The agent reads from BigQuery — running SQL it writes itself from a plain-language question — so you can join Google Ads or DV360 spend with your own GA4, CRM or revenue tables and compute true ROAS from numbers you trust, not platform-reported conversions. It's read-only: the agent queries whatever project and dataset you select in the context picker, and never creates, inserts, updates or deletes a table.

What the agent does with BigQuery

  • Writes and runs SQL against your chosen project/dataset from a plain-language question.
  • Joins ad-platform cost data (Google Ads, DV360) with your own GA4, CRM or order tables for true, margin-aware ROAS.
  • Hands off to the Python sandbox for anything SQL can't express cleanly — cohort/LTV math, custom charts.

Real use cases

Goal you'd typeWhat the agent does
"Join last month's Google Ads cost with our Shopify order revenue and give me true ROAS per campaign."Writes the SQL join keyed on campaign/date/order id and returns per-campaign profit-aware ROAS.
"What's the 90-day repeat-purchase rate for customers who came from paid search vs. organic?"Queries your CRM/orders tables joined with attribution data and computes the cohort comparison.
"Pull a custom report: spend, impressions and margin by DV360 line item for Q2."Runs the SQL directly against whatever tables hold that data in your warehouse.

Guardrails

  • Read-only — the agent never runs CREATE, INSERT, UPDATE or DELETE against your warehouse.
  • Scoped to the project/dataset you select in the context picker; it doesn't discover or query tables outside that scope.

Frequently asked questions

Can the agent write to my BigQuery tables?
No — the connection is read-only. It queries your data and returns results; it never creates, modifies or deletes tables.
Do I need to know SQL to use this?
No — describe the question in plain language and the agent writes the SQL. If you already know exactly what query you want, you can also just ask for that directly.
How is this different from just trusting Google Ads' reported conversions?
Platform-reported conversions use the platform's own attribution and can miss refunds or offline revenue. Joining spend with your own warehouse data gives you a ROAS number built from what actually happened.
