Four layers. Each one solves a different problem. None of them do what the others do.
Research reads the market before anything gets briefed. Reviews, competitor gaps, past performance, customer language. All of it processed into angles and personas with a traceable source. The raw material.
Coverage takes that material and audits how it sits across the account. What personas are missing creative. Which angles have been over-tested. What the account is telling Meta versus what it should be.
Hooks decide how each individual ad enters its territory. The hook is where every upstream decision (persona, angle, awareness level) becomes a signal the algorithm can read and a reason for the right buyer to stop. It is a targeting decision expressed in three seconds.
Lifecycle manages what happens to a signal once it starts working. Discovery, validation, expansion, saturation, decay. The goal is to extend the signal before decay forces the account into emergency creative mode.
The research stack feeds the loop. Coverage, hooks, and lifecycle run continuously from there. Read them in order, or jump to the part of the system that matches the problem in front of you.
Three playbooks that go deeper on specific parts of the research process. Not part of the main loop. Deep dives on individual sources within Layer 00.
Research and Coverage don't end in a report. They end in a creative blueprint: a matrix of distinct directions built before a single brief is written. Research surfaces the raw material, customer language, angle territory, personas defined by decision context. Coverage audits how that material sits against the account and identifies what's missing.
The map is where those two layers converge into something you can hand to a writer. Personas, awareness levels, one primary angle each. Every direction is genuinely distinct, and every one earns its own entity ID in the delivery system.
From there, Hooks decides how each direction enters the feed. Lifecycle manages what happens once something wins. When the cycle closes, the data goes back into Research and Coverage, and the map gets updated for the next round.
See it worked through: the roofing creative blueprint →Research reads the market and surfaces the angles, personas, and hook language that go into the brief. It is the only layer that works from external signal rather than account data.
Coverage takes that material and maps it across the account. Which personas have creative. Which angles are over-served. What needs to exist before the next round gets briefed. Coverage works from the inside out.
Hooks decide how each ad enters the territory coverage identified. Persona, angle, and awareness level are all decided upstream. The hook is where those decisions compress into three seconds: a signal the delivery system reads to find the right buyer, and a reason for that buyer to stop when the ad reaches them.
Lifecycle manages a winning ad through its predictable stages. The goal is extension before decay, not reaction after it. When the cycle closes, its data feeds back into research and coverage, and the process starts again.
Meta rebuilt its ad delivery infrastructure from the ground up between 2024 and 2025. The result is a system that no longer starts with the audience you defined. It starts with the creative you uploaded and works backward to find the right person. Most advertisers are still running the old playbook.
Understanding how the delivery stack works explains why coverage, hook selection, and creative diversity are not just strategic preferences. They are what the algorithm requires to function well.
Andromeda, GEM, and Lattice each have specific requirements from the creative going into them. Each of the four layers in this system addresses a different part of those requirements directly.
You are not buying access to audiences anymore. You are buying algorithmic distribution based on creative signals.
The lever you actually control is the creative. What you put in, how distinct it is, and how well it reflects a specific buyer's situation at a specific point in their decision: that is what determines how well the system works for you.
