Your agency doesn't know what a BOM is.

Most marketing agencies have never heard a buyer ask for AS9100 certification. They don't know that your Plant Manager, Engineering Director and Procurement lead all have different objections at different stages of the buying process. And they're running your campaigns.

The knowledge gap nobody acknowledges

The brief for manufacturing marketing is specific. Specification-led selling. 6-12 month sales cycles. Multi-stakeholder buying committees where technical, commercial and procurement decisions are made by different people at different times. RFQ conversion flows that bear no resemblance to an ecommerce checkout. Content that needs to work for a plant engineer at 11pm doing their own research and a procurement director presenting options to a board.

A generalist agency builds what the client asks for. A sector specialist builds what the buyer needs, before the client even knows to ask for it.

What the output looks like

The output of a generalist agency in manufacturing is predictable. Websites that look acceptable but don't convert a Plant Manager researching at 11pm. Content that reads like it was written by someone who has never been on a factory floor, because it was. Campaigns optimised for cost-per-click rather than cost-per-qualified-enquiry. And reports that show traffic and reach but cannot tell you where your last three RFQs came from.

The worth-actioning point

Ask your current agency one question: what does a qualified lead look like for a manufacturing business with a 6-month sales cycle and a three-person buying committee? If they cannot answer it immediately and specifically, your budget is working harder for their case studies than it is for your pipeline.
