Rank tracking with the SERP API: hiking boots searched on Google from Denver, Colorado on mobile, the results page in the middle with a rank on every row and haixusa.com at position 2, and the row to store with query, location, device, rank and source. Plain page, as the answer says: $0.0009 per search. — Rank tracking by city and device: every result carries its rank, and you store one row per check.

How it works

Search, then find your domain.

A rank tracker needs three things from a search: the right place, the right device and enough results to find you. The SERP API takes location (a city or coordinates), device (desktop or mobile) and num, and returns the organic results with their rank, link and domain.

Example

100 keywords, three countries, one script.

import requests

KEYWORDS = ["hiking boots", "trail running shoes"]   # up to as many as you track
DOMAIN = "example.com"
for country in ["us", "gb", "de"]:
    for kw in KEYWORDS:
        r = requests.post("https://api.quanticdata.io/v1/scraper/serp",
            headers={"Authorization": "Bearer YOUR_API_KEY"},
            json={"query": kw, "country": country, "device": "mobile", "num": 100})
        organic = r.json()["payload"]["organic"]
        pos = next((o["rank"] for o in organic if DOMAIN in o["link"]), None)
        print(country, kw, pos)

Python: position of one domain for each keyword and country

For many keywords at once, send them as one job to /v1/serp/bulk and collect the results when it is done. To schedule it without code, the n8n node and the MCP server run the same call.

Location and device

Rankings change by city and by phone.

Parameters that make a ranking local
Parameter	What it does
`location`	Human-readable place ("Denver, Colorado"), encoded server-side; or `uule` with lat,lon
`country`	Market and proxy exit (gl)
`device`	`desktop`, `mobile`, `ios`, `android`: the results page a phone gets
`num`	Results to read (up to 100), so you find positions beyond the first page
`engine`	`google`, `bing`, `duckduckgo`

How deep can I look?
