Audience Architect for metal fabrication

Your account targets OEM procurement leads, engineering designers, and quality managers — but you're running all three through one audience layer and wondering why ROAS is flat. Audience Architect translates your job-title list plus industry into the targeting structures you need: custom segments (built from search behavior and site affinity), in-market audiences (showing active B2B buying intent), observation layers (learning from competitor site visitors). For metal fabrication, you segment procurement leads (cost-driven, vendor-evaluation focused) from engineering leads (capability-driven, DFM-focused) from quality managers (certification-driven, compliance-focused). Each gets different bid strategies, different landing-page destinations, and different ad copy (procurement talks cost; engineering talks capability; quality talks documentation). Audience Architect sizes each layer so you're not accidentally shrinking your reach to nothing with overly-tight targeting. The outputs are editor-ready segment lists so your team can build audience layers quickly without guessing. Recommendation: build separate audience layers per job title and run them as observation-only initially to validate size. Once you confirm segment viability, split them into separate campaigns per layer so you can optimize bid strategies per persona.
