Audience Architect for industrial controls

Building audience layers for industrial controls requires translating three dimensions — job title (controls engineer, plant manager, IT lead), company size ($10M to $1B revenue), and ecosystem preference (Rockwell, Siemens, Schneider, Mitsubishi) — into the audience segments Google Ads actually lets you target. Most accounts try to build segments manually and end up with either too many (fragmented reach) or too few (no signal). Audience Architect takes a list of job titles and industries and suggests the audience-layer structure: which job titles belong in the same custom segment, which should be observation-only, which should be explicitly excluded. For controls, the output might be: Controls Engineers + Plant Automation Managers in one audience (both drive technical evaluation), IT Directors in a separate observation audience (they see the ads but are not targeted directly — the ads have to prove value first), and Procurement Leads in a third segment with restricted reach (only show to them when they are actively searching). Audience Architect also estimates segment sizes — 'Segment 1: Controls Engineers + Plant Managers targeting Rockwell keywords, 250K people' — so you know whether you have reach. Recommendation: run Audience Architect with your three primary personas. Use the output to build three separate ad-group structures, not three separate campaigns — this preserves reach while keeping the audience layers distinct.
