Intent Classifier for industrial controls

Industrial controls search terms exist on a spectrum from early-stage research ('difference between Rockwell and Siemens PLC') to late-stage purchase signals ('CompactLogix 5380 processor in stock'). Most accounts don't structure their campaigns differently by intent stage, which causes a single ROAS target to average out into poor performance at both ends. Intent Classifier routes search terms into TOFU (top of funnel: early research, comparison, education), MOFU (mid-funnel: specification research, proof-of-concept), BOFU (bottom-of-funnel: buying signals, quote requests), and EXISTING (existing customer, support, upgrade queries). For controls, TOFU queries look like 'Allen-Bradley versus Siemens PLC comparison', 'what is a gateway in industrial controls', 'Modbus to EtherNet/IP'; MOFU queries look like 'Studio 5000 v33 Ethernet IP module price', 'Modbus TCP gateway latency specifications'; BOFU queries look like 'CompactLogix 5380 in stock', 'ControlLogix spare parts'; EXISTING queries look like 'Studio 5000 software update', 'gateway firmware patch'. Each stage wants different landing pages and different bid strategies. Recommendation: run Intent Classifier on your top 100 search terms quarterly. Build separate campaigns per intent stage — route TOFU to educational landing pages and blogs with tCPA bidding, MOFU to specification pages with manual CPC, BOFU to quote-request forms with maxConversions bidding.
