Measuring AI's Effect on Your Marketing

A research team measured how badly people misjudged their own speed-up when they worked with AI. The error averaged **39 percentage points**. That number is bigger than the effect you are trying to measure — which is why you need four metrics, not an impression.

Competitor Monitoring with AI

A weekly automated digest can technically be put together in half a day. The question is not whether it works — it is what you are allowed to monitor, and what you do with what you found out. Because in price monitoring, according to an EU court judgment, even *becoming aware* has consequences.

AI Sales Agents and Outbound: Where It Breaks

AI Sales Agents and Outbound: Where It Breaks

Platform data covering 53 million cold emails shows that campaigns aimed at target groups under 200 people bring roughly twice the reply rate of those over 500. Which is the exact opposite of what automation promises. And that is only the arithmetic — the legal part is harder.

Personalization Without Creeping People Out

The same heavily personalized ad scored 4.38 on click intent when the company collected the data openly, and 3.16 when it collected it covertly. What decides is not the degree of personalization but whether the customer understands how you know. And there is a cheap fix for it, which was also measured.

Customer Research from Reviews and Support Tickets

Customer Research from Reviews and Support Tickets

An analysis of 18,682 Amazon reviews showed that when the language style of a text matches the reader's, conversion goes up — and that a shift in negative content moves the needle harder than a shift in positive content. Your customers' words are not a matter of mood, then. You only have to know where you are allowed to take them from.

Email Marketing: Segmentation and Copy with AI

Three pre-registered experiments, 27,500 customers each, on real newsletters: the AI-written email brought in exactly as much as the paid copywriter's. The AI still won — on cost. And meanwhile the open rate, the number everybody watches, has stopped measuring anything.

A Social Media Calendar with AI

A month's plan really can be put together in half a day — just not by asking the machine to write thirty post ideas. The method is about topic buckets, not about the number of posts. And the frequency figures everybody quotes do not prove what you think they prove.

Ad Creative at Volume: Process, Not Magic

In one peer-reviewed measurement, AI creative had a 0.98% click-through rate against the designer's 0.65%. Eighteen months later it was 3.38% against 3.24%. The advantage held, but it shrank — and in the meantime labelling became mandatory. Those two together decide what is worth doing.

Landing Page Copy: Testing Variants Fast

You really can write five variants in forty minutes. Which one wins is something 161,358 visitors decide at a 2% conversion rate — and if you want to detect an effect half that size, four times as many. This post is about what to do until then.

Building Topic Clusters and Pillar Pages with AI

The source of the method is a nine-year-old company report with no sample size and no control group. The search engine officially recognises no such signal. And on AI answers there is zero data. It is still worth doing — just not for the reason people give.

Content Briefs That Produce Publishable Drafts

The first AI draft is generic because the brief was generic. Seven fields that change the outcome — plus an honest note on which of them measurement backs up and which it does not.

Keyword Research with AI, Without the Fluff

Ask a model how many people search for a phrase each month and you will get a number. The number is invented. But there are four jobs in keyword research where a language model really is better than any tool — and one where it is measurably worse.
