Proxies for Ad Verification

Ad verification is checking correct ad display. Proxies allow seeing ads through the eyes of users from different regions.

Verification Tasks

Brand Safety

• Ads don't appear next to unwanted content
• Placement context compliance

Viewability

• Ad is actually visible to user
• Correct size and position

Geo-compliance

• Ads displayed in correct regions
• Targeting compliance

Fraud Detection

• Bot traffic detection
• Impression reality verification

Why Proxies are Needed

Ad networks show different content depending on:
- User geolocation
- Device type (mobile/desktop)
- Browser history
- Time of day

Proxy Types for Ad Verification

Residential

• Real home user IPs
• High trust score
• Suitable for all ad networks

Mobile

• Mobile carrier IPs
• For mobile ad verification
• Best real user simulation

Verification Example

import requests
from selenium import webdriver

def check_ad_in_region(url, country, city=None):
    # Get proxy for region
    proxy = get_proxy(country=country, city=city)

    # Setup browser
    options = webdriver.ChromeOptions()
    options.add_argument(f'--proxy-server={proxy}')

    driver = webdriver.Chrome(options=options)
    driver.get(url)

    # Find ad elements
    ads = driver.find_elements_by_css_selector('[data-ad-slot]')

    for ad in ads:
        screenshot = ad.screenshot_as_png
        ad_content = ad.get_attribute('innerHTML')
        # Analyze ad content
        analyze_ad(screenshot, ad_content, country)

    driver.quit()

# Check in different regions
regions = ['US', 'UK', 'DE', 'FR', 'JP']
for region in regions:
    check_ad_in_region('https://example.com', region)

Best Practices

1. Use different proxy types — residential and mobile
2. Check at different times — ad campaigns change
3. Save screenshots — for evidence and analysis
4. Automate the process — regular checks
5. Compare results — between regions and time
