Your best-performing channel might just be a passenger

Last-click and even a mix model can flatter the spend that only harvested demand it never created. Incrementality testing is the causal tie-breaker: geo experiments and holdout lift tests that show which dollar actually caused a sale.

Do you actually need a CDP in 2026, or is the warehouse enough?

Packaged customer data platforms and warehouse-native, composable stacks now do most of the same jobs. The real fork is not buy vs build. It is where you put identity and consent, and how fast you need to act on them.

The referral fee is the smallest line on your Amazon bill

Amazon called its 2026 fee change slight, and for one unit it is. The real cost of selling on Amazon and Walmart sits underneath it: a stack of fulfillment, storage, and ad charges that turns a 6-15% referral into something operators put near 30-40% of gross merchandise value (GMV), and each platform hurts in a different place.

How to get quoted by the machine that replaced your search traffic

Generative engine optimization isn’t SEO with a new coat of paint. It’s writing for extraction (answer-first, evidence-dense, cleanly structured) so ChatGPT, AI Overviews, and Perplexity pick you as the source. This piece is built the way it tells you to build.

The average LinkedIn CPC is a number that will lose you money.

Published 2026 benchmarks put LinkedIn cost per click (CPC) anywhere from $5.58 to $10.11, and as high as $15.72 in peak quarters, with cost per lead (CPL) from $15 to $350. The spread isn’t noise. It’s the whole game. Plan to the range that matches your audience, not the headline that matches nobody’s.

Automate the plumbing, not the judgment: n8n and Make

RAG for marketing: how to ground an LLM in your own brand knowledge

Retrieval-augmented generation is how you stop a large language model (LLM) from inventing your product facts. In 2026 the work is a governed pipeline, not a prompt, and the payoff is brand-safe content and support you can actually audit.
