I've spent years inside the Amazon ecosystem, which is a very different beast from B2B or DTC content marketing, but I see the same pattern playing out across channels. Everyone is producing content because it feels productive-like watering a garden without ever checking if the soil chemistry actually supports growth.
i recall a similar discussion where someone described post-purchase interviews with customers, trying to trace which piece of content genuinely influenced a buying decision. The sample was small, but the result was sobering: not a single one could point to a blog post, white paper, or industry trend piece. It's a tiny data set, sure, but it echoes what I see in PPC. most impressions are noise. The difference is that on Amazon, the feedback loop is brutally short-you know within hours if a keyword or creative is losing money.
The real issue for agencies and brands is that the content calendar has become a sacred cow. It gives the illusion of strategy when really it's just a schedule of output. We treat white papers and case studies like assets that must be produced because "that's what B2B does," yet we rarely isolate their actual contribution to revenue.
For me, the only content that matters is content that captures intent at the moment of search-or content that reshapes the consideration set before a search even happens. Everything else is overhead. I'd rather test one tightly targeted piece across two different placements and measure lift in direct response than pump out a calendar full of educated guesses.
Would be interested to hear if anyone has run controlled experiments on longer-form content directly influencing closed deals, or if it's all just feeding the SEO machine under the guise of authority.
