Does ZipFencer work for Performance Max location exclusions?
Yes. Performance Max location targeting lives at the campaign, so ZipFencer builds ZIP inclusion and exclusion lists you paste into campaign location settings — not the asset group. Drop a pin or import locations, choose an exclude-focused mode such as a donut or exclude-only ring, then export paste batches or Google Ads Editor CSV on Starter and Pro. Use the exclusion list to cut geo bleed outside the area you serve. Lists use Census ZCTA polygons; Google Ads may expand ZIP reach slightly beyond the ZCTA shape, so treat this as a practical control rather than a pixel-perfect match to Google's map. ZipFencer does not auto-sync live Ads — revisit exclusions with geo reports.
