# Google Search Adlibrary Advertisers Search API (https://www.socialcrawl.dev/platforms/google/adlibrary-advertisers-search)

> Searches the Google Ads Transparency Center for advertisers matching a query. Returns matching advertisers with `name`, `advertiser_id`, and `region`, plus their website domains. Defaults to US when `region` is omitted — pass a 2-letter country code (e.g. `AU`, `CA`) to search advertisers in another region.

TL;DR: `GET /v1/google/adlibrary/advertisers/search` costs 5 credits per call and returns SocialCrawl's unified JSON schema. Single x-api-key auth, 100 free credits on signup.

## Parameters

| --- | --- | --- |
| `query` | yes | Search keyword or phrase to find advertisers in the Google Ads Transparency Center. |

## FAQ

### How do I search the Google Ad Library with an API?

Send a GET request to /v1/google/adlibrary/advertisers/search with a brand or keyword in the query parameter. SocialCrawl queries the Google Ads Transparency Center and returns matching advertisers: name, verified status, region, and total ad count per advertiser.

### What does each advertiser search result include?

Advertiser name, advertiser ID (use it with the company/ads endpoint), verification status, primary region of operation, and the total number of ads that advertiser has run on Google surfaces in the Transparency Center's tracked window. Perfect as a lookup step.

### Can I monitor a brand's Google ad portfolio?

Yes. Run advertisers/search with the brand name as the query on a cron, grab each advertiser_id, then call company/ads with that ID to list every ad the brand is running: creatives, regions, and date ranges included. Two endpoints = full competitor ad intelligence.

### How is this different from the Google web search endpoint?

The Google Search API returns organic SERP results: web pages ranked by Google's index. This endpoint returns advertisers from the Ads Transparency Center (companies running ads on Google) with ad counts. Use SERPs for SEO research, this for ad research.

### How much does the Google Ad Library API cost?

Each advertiser search costs 5 credits on the advanced tier because the Transparency Center requires heavier upstream rendering. New accounts get 100 free credits, enough for 20 advertiser lookups, or mix it with the 1-credit SERP endpoint for broader research.
