SEO and SERP tracking

The problem

Search engines localise results down to the city and adapt them to the device and network. A rank tracker running from a datacentre in Frankfurt does not see what a searcher in Lyon sees, and its requests are quickly answered with consent walls, CAPTCHAs or HTTP 429 responses.

Accurate tracking therefore needs many independent requests from residential addresses in the right city, spread over enough IPs that no single address carries a recognisable query pattern.

Configuration

Product

Rotating residential, billed per GB

Rotation

Per request (no session parameter)

Targeting

-country-fr-city-lyon, one city per tracked market

Request headers

Accept-Language and hl/gl parameters matching the target country

Concurrency

10–30 parallel requests per market; spread keywords over the day

Typical volume

A results page weighs 150–400 KB, so 1 GB covers roughly 3,000–6,000 queries

Example

import random, time
import requests

LOGIN, PASSWORD = "px7h2k9m4q", "Rq4Tn8Vw2Lx6Bz9C"

def fetch_serp(query, country="fr", city="lyon"):
    user = f"{LOGIN}-country-{country}-city-{city}"
    proxy = f"http://{user}:{PASSWORD}@resi.gw.proxuno.com:7000"
    r = requests.get(
        "https://www.google.com/search",
        params={"q": query, "hl": "fr", "gl": country, "num": 20},
        headers={"Accept-Language": "fr-FR,fr;q=0.9"},
        proxies={"http": proxy, "https": proxy},
        timeout=30,
    )
    r.raise_for_status()
    return r.text

for keyword in ["avocat droit du travail lyon", "plombier lyon 3"]:
    html = fetch_serp(keyword)
    time.sleep(random.uniform(2, 5))

Best practices

• Match the language parameters and the Accept-Language header to the targeted country; mismatches produce mixed-language results.
• Do not reuse cookies between queries. Personalisation from one search leaks into the next.
• Retry a CAPTCHA or 429 response once through a new IP, then back off for that keyword instead of hammering it.
• Store the raw HTML with the timestamp and the exit country so ranking changes can be audited later.
