Sync data from Snowflake to Google Ads
Activate your Snowflake data by syncing it directly into Google Ads. With Weld's reverse ETL, you can push enriched and transformed data such as Tables, Views, Schemas, and Databases from your database into Google Ads, making it actionable for your team without manual exports or CSV uploads.

Why sync Snowflake to Google Ads?
Push enriched segments and computed attributes from Snowflake into Google Ads to power personalized outreach and targeted campaigns.
Keep Google Ads updated with the latest data from Snowflake to automate workflows and reduce manual data entry.
Common use cases
Audience activation
Build audiences from Snowflake data and sync them to Google Ads for targeted campaigns without manual list exports.
Conversion tracking
Send conversion events and offline purchase data from Snowflake to Google Ads to improve attribution and ad optimization.
Operationalize analytics
Turn insights from your database into action by pushing model outputs and metrics into Google Ads where your team works.
What data can you sync?
You can sync transformed, enriched data from Snowflake to Google Ads. The specific fields and objects depend on what you model in your database using SQL or dbt transformations.
How to set up Snowflake to Google Ads in Weld
Connect your database
Add Snowflake as a data source in Weld by providing your connection credentials. Weld connects securely using encrypted tunnels and never stores raw credentials — only the OAuth token or connection string needed for read access.
Define your transformation
Write a SQL query or dbt model that selects and transforms the data you want to push to Google Ads. This is where you build audience segments, compute lead scores, aggregate metrics, or reshape data into the structure Google Ads expects. You can preview results before activating.
Connect Google Ads
Authenticate Google Ads as a reverse ETL destination. Weld supports OAuth or API key authentication depending on the connector. Once connected, Weld automatically discovers the available objects and fields in Google Ads.
Map fields and configure sync
Map your SQL columns to Google Ads fields using Weld's visual mapper. Choose your sync mode — insert (create new records), update (modify existing), or upsert (create or update) — and set a schedule from every 5 minutes to daily.
Activate and monitor
Enable the sync and monitor it from the Weld dashboard. Track record counts, sync duration, and error rates in real time. Configure Slack or email alerts so you're notified immediately if a sync fails or encounters data quality issues.
ELT vs. reverse ETL: Snowflake and Google Ads
ELT (Extract, Load, Transform) moves data from Google Ads into Snowflake for analytics. It's about centralizing data in your warehouse so analysts can query and join it with other sources.
Reverse ETL does the opposite — it takes data that's already in Snowflake and pushes it into Google Ads so operational teams can act on it. This is the approach used on this page.
Many teams use both: ELT to centralize data in the warehouse, and reverse ETL to activate that data back in business tools. Weld supports both directions between Snowflake and Google Ads.
Technical considerations
Sync modes
Choose between insert, update, or upsert sync modes when pushing data to Google Ads. Upsert is recommended to avoid duplicates.
Rate limits
Weld respects Google Ads's API rate limits and automatically throttles requests to avoid hitting quotas.
Data freshness
Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
Security
All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
Frequently asked questions
How do I sync Snowflake data to Google Ads?
Sign up for Weld, connect Snowflake as a source and Google Ads as a reverse ETL destination. Weld handles the extraction, loading, and lets you transform data using SQL or dbt.
What Snowflake data can I sync to Google Ads?
You can sync Tables, Views, Schemas, and Databases. The available objects depend on your Snowflake account permissions and configuration.
How often does Weld sync data from Snowflake?
Sync frequency depends on your Weld plan. Schedules range from every 5 minutes to daily intervals. Each sync processes only new and changed data.
What is reverse ETL and how does it work with Google Ads?
Reverse ETL takes data from a warehouse or database and pushes it into operational tools like Google Ads. With Weld, you write a SQL query to define what data to sync, map it to Google Ads fields, and schedule the sync.
Is the Snowflake to Google Ads integration secure?
Yes. Weld encrypts all data in transit and at rest, is SOC 2 Type II certified, and supports IP whitelisting. Credentials are stored encrypted and never logged.
Can I also sync data from Google Ads to Snowflake?
Yes. Weld supports both directions. You can use ELT to pull data from Google Ads.
