ZipFencer vs Google Radium
Both generate radius-based ZIP lists for Google Ads. Google Radium is a free open-source script you self-host in Google Sheets. ZipFencer is a finished web app with polygon zones, bullseye tiers, and an exclusion-first workflow built for Performance Max.
Google Radium
Open-source Apps Script
An Apps Script project that runs inside a Google Sheet to generate radius-based geo targeting CSVs. Powerful if you're comfortable with scripts — there's no UI, you configure runs in spreadsheet cells.
ZipFencer
Web app — built for Google Ads
Address-anchored ZIP rings, donut and bullseye tiers, polygon zones, and Google Ads CSV export in one workflow. No setup — sign in and you're targeting in seconds.

Custom polygon zones Draw any shape on the map for non-circular service areas | ||
Exclusion list for PMax surrounding ZIPs | ||
Google Ads bulk-upload CSV | ||
No setup required Radium needs Apps Script + sheet template setup | ||
Named saved searches with cloud sync | ||

When Google Radium makes sense
Developer-leaning advertisers who want a free, self-hosted tool and don't mind setting up Apps Script, copying templates, and editing spreadsheet config to run a job.
Where it falls short for Google Ads
- Requires Google Apps Script setup, sheet templates, and config knowledge — not a tool a marketer can hand to a junior.
- Radius targeting only — no donut, no bullseye tiers, no polygon zones for non-circular service areas.
- No exclusion-first workflow for Performance Max — generating the surrounding-ZIPs exclusion list is manual.
- No saved/named campaigns to reload later — every run starts from spreadsheet config.
- No cloud sync, no team access controls, no history — whatever lives in the sheet is what you've got.
If you're a script-comfortable PPC engineer and you only need basic radius targeting, Google Radium is free and gets the job done. If you need bullseye tiers, polygon zones, or PMax exclusion lists — and you'd rather click than code — ZipFencer is the faster path.
