Why this needs proxies
Sites vary what they return based on where the request appears to come from, and they rate-limit or block addresses that ask too often. Both problems have the same fix: exit from real consumer IPs in the right places, and spread the load so no single address looks unusual. That is the whole job a proxy does here.
The reason residential IPs succeed where datacenter ones fail is classification by ASN. Hosting networks can be challenged wholesale with a single rule; consumer ISP networks cannot, because doing so would block real customers.

Start with the cheapest option your target tolerates and move up only when it blocks you. Concurrent sessions are unlimited on every plan and country targeting is included in the price. Full tiers are on our pricing page.
How this works in practice
- Pick the cheapest product that works. Test the target on rotating datacenter first; move to residential only when you are actually refused.
- Choose the exit country deliberately. The data you get back is the data that country sees, so record which exit produced every record.
- Decide rotation vs sticky. Per-request rotation suits stateless collection; anything with a login or a multi-step flow needs one IP held for the whole session.
- Pace against the target, not your budget. Back off on 429 responses instead of rotating past them, and randomise intervals rather than hitting on the hour.
Common mistakes
- Rotating inside a session. The single most common cause of empty results and flagged accounts.
- Mismatched signals. An exit in one country with an Accept-Language header for another creates a visitor that does not exist, and some sites respond to the contradiction.
- Paying for residential too early. Plenty of targets never check, and the gap between $1.00/GB and $2.75/GB is substantial at volume.
- Not recording the exit. Data without its point of observation cannot be compared across markets.
Sizing your bandwidth
Work from page weight rather than guesswork. A page averaging 250 KB across 100,000 requests is roughly 25 GB. JSON APIs are far lighter, often a few kilobytes per call, while anything rendered in a headless browser pulls images and scripts too and can be several times heavier. Start at 1 GB, measure your actual average, then buy the package that matches.
Getting set up
Every product speaks HTTP(S) and SOCKS5, so this is a one-line change in most stacks. Credentials are assembled from a variable below rather than pasted inline, because a literal user:pass@host string in page copy can be rewritten by email-obfuscation filters.
import requests
endpoint = "geo.spyderproxy.com:12321"
creds = "USERNAME:PASSWORD"
proxy = f"http://{creds}@{endpoint}"
r = requests.get(
"https://example.com",
proxies={"http": proxy, "https": proxy},
timeout=30,
)
print(r.status_code)Confirm your exit is landing where you expect with the IP lookup tool before starting a long run. Bandwidth products begin at 1 GB, so you can validate for under $2.
Frequently Asked Questions
Why do I need proxies for ad verification?
Ad servers target by geography, so the creative you see from your office is rarely the creative your audience sees. Checking from a residential IP in each market is the only way to confirm what actually rendered.
Can I detect ad fraud with proxies?
You can detect misplacement, geo-mismatch and cloaked landing pages by loading placements from real consumer IPs across markets. Proxies give you the vantage point; the fraud analysis is yours.
Which product suits ad verification?
Budget Residential at $1.75/GB for breadth across markets, or Premium Residential at $2.75/GB when you need to verify a specific city's placements.
