100K-Listing Scrape Reveals Google Hides GBP Services from Data Center ASNs

Data center proxies pulling Google Business Profile (GBP) results return stripped or altered service lists, reveals Ted Kubaitis.

To block mass extraction by LLMs and competitors, Google filters local data based on the request's Autonomous System Number (ASN) and IP reputation.

Extracting 100,000 listings within a two-hour window requires routing all requests exclusively through residential IPs; firing the exact same scrape via data center ASNs triggers the filter and returns a sanitized payload missing core service data.

Separately, the algorithm weaponizes user interaction to block headless scraping in the map pack.

Google actively hides local business phone numbers from the initial HTML response.

The system reveals the contact data only when a cursor triggers a specific hover event over the element.

To capture this content, scrapers must execute JavaScript to physically spoof the mouse-over interaction before parsing the DOM.
