Tactics that worked from 2018-2022 (cheap paid, retargeting, basic SEO) are getting less reliable as privacy and AI reshape attention.

What scales now is not a “meta hack” but a clear marketing operating system that can survive platform shifts.

Why channel‑first breaks

• Over‑dependence on a few performance channels makes you fragile to auction inflation, tracking loss, and algorithm changes.

• AI has compressed creative cycles: everyone can ship more ads, faster, which makes channels noisier and drives up CPCs.

• Teams end up chasing short‑term CPA while ignoring positioning, message, and distinctive creative that actually move the market.

What a “marketing OS” looks like

[1] Clear ICP and problem thesis:

• Document who you’re for

• the key jobs/pains

• what “success” looks like in their words

[2] Three core motions instead of ten scattered tactics:

• Demand creation (brand, content, community, OOH/earned).

• Demand capture (search, marketplaces, review sites, website).

• Acceleration/expansion (email, product marketing, customer marketing).

[3] Shared GTM rhythm with sales and product:

• Weekly: pipeline + campaign review.

• Monthly: segment performance, experiments, backlog for next cycles.

How to operate it in 2026

[1] Measurement:

• Use click data to optimise capture, HDYHAU + MMM (when big enough) to see if creation is working, and always tie back to pipeline + CAC payback.

[2] Creative and differentiation:

• Explicitly carve 20–30% of budget/time for untrackable but high‑leverage bets (brand campaigns, outbound plays, community, “weird” creative), judged on lagging impact to direct traffic, branded search, and win‑rates.

[3] Feedback loops:

• Systematically capture learning from wins/losses, sales calls, and customer interviews into messaging and campaign briefs.

Final learnings

A resilient marketing engine is system‑led, not channel‑led: it can swap tactics in and out without losing its spine.

If you get ICP, motions, rhythm, and measurement right, you can ignore 90% of “growth hacks” and still outperform peers as the environment keeps changing.

That's it for today's article! I hope you found this essay insightful.

Wishing you a productive week ahead!
