# 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. |
| `region` | no | 2-letter country code to search in. Defaults to US. |

## 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.
