Learn how to scrape Google Ad Library ads using Go. This comprehensive guide will walk you through the entire process, from setup to implementation.
First, you'll need a ScrapeCreators API key to authenticate your requests.
Sign up at app.scrapecreators.com to get your free API key with 100 requests.
Make sure you have the following installed:
Resty is a simple HTTP and REST client library for Go
go get github.com/go-resty/resty/v2Now let's make a request to the Google Ad Library API using Go. Replace YOUR_API_KEY with your actual API key.
package main
import (
"fmt"
"io"
"net/http"
"net/url"
"time"
)
const (
API_KEY = "YOUR_API_KEY"
BASE_URL = "https://api.scrapecreators.com"
ENDPOINT_PATH = "/v1/google/ad"
)
func main() {
result, err := scrape()
if err != nil {
fmt.Printf("Error: %v", err)
return
}
fmt.Printf("Response: %s", result)
}
func scrape() (string, error) {
client := &http.Client{
Timeout: 30 * time.Second,
}
// Build query parameters
params := url.Values{}
params.Add("url", "https://adstransparency.google.com/advertiser/AR07541154843046445057/creative/CR17778900238552006657")
params.Add("cache_max_age", "7d")
req, err := http.NewRequest("GET", BASE_URL+ENDPOINT_PATH+"?"+params.Encode(), nil)
if err != nil {
return "", err
}
req.Header.Set("x-api-key", API_KEY)
req.Header.Set("Accept", "application/json")
resp, err := client.Do(req)
if err != nil {
return "", err
}
defer resp.Body.Close()
if resp.StatusCode != http.StatusOK {
body, _ := io.ReadAll(resp.Body)
return "", fmt.Errorf("HTTP %d: %s", resp.StatusCode, string(body))
}
body, err := io.ReadAll(resp.Body)
if err != nil {
return "", err
}
return string(body), nil
}This endpoint accepts the following parameters:
urlRequired(string)The url of the ad
Example: https://adstransparency.google.com/advertiser/AR07541154843046445057/creative/CR17778900238552006657
cache_max_ageOptional(select)If we have a response in the cache that is this many days old or newer, return the cached response (0 credits, with "cached": true and a "cached_at" timestamp). Otherwise, scrape a live result (1 credit). [See the Caching page for details.](https://docs.scrapecreators.com/caching)
Example: 7d
Execute your script to test the API connection. You should see a JSON response with Google Ad Library ads data.
β Success: You should receive a structured JSON response containing the requested data.
Here's an example of the JSON response you'll receive:

}Check that your response includes the expected fields:
success(boolean)credits_remaining(number)credits_charged(number)advertiserId(string)creativeId(string)Implement comprehensive error handling and retry logic for failed requests. Log errors properly for debugging.
Cache responses when possible to reduce API calls and improve performance. Consider data freshness requirements.
Never expose your API key in client-side code. Use environment variables and secure key management practices.
When scraping multiple ads, consider batching requests to maximize throughput while staying within rate limits.
Use asynchronous processing in Go to handle multiple requests concurrently and improve overall performance.
Analyze Google Ad Library ads to understand market trends, competitor analysis, and audience insights.
Track performance metrics, engagement rates, and content trends across Google Ad Library ads.
Identify potential customers and business opportunities throughGoogle Ad Library data analysis.
Check your API key is correct and properly formatted in the x-api-key header.
You ran out of credits and need to buy more.
The resource might not exist or be private.
Temporary server issue. Implement retry logic with exponential backoff.
ScrapeCreators offers 100 free API calls to get started. After that, pricing starts at $10 for 5k requests with volume discounts available.
Scraping publicly available data is fair game, and we only collect public data. So anything that you can see in an incognito browser is what we collect.
There is no rate limit! So you can scrape as fast as you want!
All API responses are returned in JSON format, making it easy to integrate with any programming language or application.
Yes! This tutorial focuses on core Go HTTP concepts that work with any framework. The API calls remain the same regardless of your specific Go setup.
For large datasets, implement pagination, use streaming responses where available, and consider storing data in a database for efficient querying.
