A 5-step checklist to validate generative ai marketing copy without hallucinations or seo loss

I use generative AI for marketing copy all the time — landing pages, social hooks, product descriptions — but I don’t trust it blindly. Left unchecked, AI can invent facts (hallucinate), introduce subtle SEO problems, or produce copy that reads well but won’t convert. Over the last couple of years I’ve refined a short, repeatable validation checklist that catches the usual failure modes without slowing down creative velocity. Here’s the 5-step approach I run every draft through...

Why your creative briefs fail and a one-page template that gets faster approvals from stakeholders

I’ve reviewed enough creative briefs to fill a small archive room. The ones that ship projects forward quickly are rare; most are either a dense PDF nobody reads or a vague Slack thread that spawns three rounds of “clarifying” feedback. If you’re frustrated by slow approvals, missed creative intent or endless revision cycles, the problem usually isn’t the creatives — it’s the brief.Why most creative briefs failFrom my experience...

How to run a low-budget product review series that builds trust and drives affiliate revenue

I run product reviews for a living, and over the years I’ve learned that a high production budget isn’t a prerequisite for building trust or earning affiliate revenue. What matters is consistency, transparency, and an approach that treats reviews like a helpful conversation rather than a sales pitch. In this piece I’ll walk you through a practical, low-cost framework to launch a review series that builds credibility, grows an audience, and...

How to create a creative studio workflow in figma that halves iteration time with external freelancers

I’ve been running creative projects that mix in-house teams and external freelancers for years, and the single biggest time sink we used to fight was iteration friction: handing off work, getting feedback, updating files, re-sharing versions, and repeating. Figma changed a lot of that, but only when we paired the right file structure, component strategy and collaboration rules with a simple handoff and feedback process. Over time I refined a...

Why most social listening tools miss brand sentiment and how to calibrate them for accuracy

Most social listening dashboards promise a single pane of truth: sentiment over time, share of voice, and a neat green-yellow-red indicator that supposedly tells you how people feel about your brand. In practice, those signals are noisy, misleading, and often dangerously overconfident. I’ve built and audited listening setups for brands and agencies for years, and I keep seeing the same failure modes: missed sarcasm, ignored context,...

A step-by-step plan to migrate event tracking from ga3 to ga4 without data gaps

I remember the first time I had to migrate an entire event tracking setup from Universal Analytics (GA3) to Google Analytics 4 (GA4): it felt like defusing a bomb while trying to keep the lights on. The key to getting it right is planning, mapping and running both systems in parallel until you're confident the new implementation is capturing everything you need. Below is the step-by-step plan I use with clients to migrate event tracking without...

How to run a product review lab: testing methodology, scoring rubric and publishing cadence

I run a small product review lab at Mediaflash Co where the emphasis is simple: test like a skeptical user, measure like an analyst, and write like a peer. Over the past few years I’ve iterated a process that balances speed and rigor — fast enough to keep up with product cycles, rigorous enough that readers can actually rely on the recommendations. Below I walk through the testing methodology I use, the scoring rubric that keeps reviews...

The exact analytics events you must track for subscription onboarding on next.js sites

On subscription products, the onboarding flow is where you win or lose customers. I’ve spent years instrumenting flows for SaaS and content subscription businesses, and one thing keeps coming up: teams either track too little (so they can’t diagnose churn/handoff points) or they track too much (raw data with no action). Below I share the exact analytics events I recommend for subscription onboarding on Next.js sites — what to capture, when...

Why your brand voice feels generic and a simple framework to make it shareable on social

I used to get asked all the time: “Why does our brand voice feel...forgettable?” It’s a polite way of saying “generic.” I’ve seen teams pour hours into tone of voice documents, only for social posts to end up sounding like a bland corporate echo of every other brand in their category. The problem isn’t always a lack of creativity — it’s a lack of constraints that make creativity repeatable and recognisable.Why brand voice...

How to audit your first-party data flow so ad targeting survives third-party cookie loss

The end of third-party cookies didn’t come as a single knockout blow — it was a slow, predictable squeeze. But for many teams, the real challenge isn’t the headline change; it’s the messy, fragile plumbing of first-party data that suddenly matters a lot more. If you want ad targeting to survive and thrive in a cookieless world, you need to audit your first-party data flow end-to-end. I’m going to walk you through a pragmatic, hands-on...

How to choose the right martech stack for a two-person marketing team under £5k/year

Picking a martech stack for a two-person marketing team on a tight budget is less about finding the single "best" tool and more about choosing a set of services that work together, reduce overhead and scale sensibly. I’ve built and audited stacks for tiny teams and large brands, and the constraint that matters most isn’t money — it’s attention. With £5k/year, you can cover the essentials if you prioritise integration, automation and...
