Four chapters, one for each craft and one for the loop. Every chapter has a hands-on project with a before-and-after number, plus the best free courses and videos we could find.
You can explain the system and produce a supervised piece of work. Finishing the four chapters is a Foundation step.
You can deliver, monitor and improve the system in a live account with routine review.
You can design safeguards and trade-offs across a team, and teach others.
Levels are per craft: someone can be Advanced in Creative and Foundation in Signal. The chapters take about ten hours if you already work in paid media; that is an entry point, not a qualification. Practitioner and Advanced come from doing the work on real accounts. Capabilities by level ›
Platforms optimise toward the conversions you send. This chapter makes sure those conversions are real, complete and worth something.

Become a PME / Chapter III · creative / Deep dive
Chapter III · deep diveEvery platform crops, overlays and rebuilds your ad in its own way. This page covers the four things a creative agent needs before it can make anything worth testing: the right sizes, the brand inputs, a layout that reads in a second and a research loop that teaches it what wins.
Design for the tallest frame first, then crop down. Keep the message inside the safe zone so no caption, button or profile bar covers it.
Facebook · Instagram
Default for feed. 1:1 still runs but gives up screen.
One safe zone for both: keep 14% top, 35% bottom, 6% sides clear.
1:1 also works. Keep every card in the same ratio.
Fallback for older placements.
No separate logo field: the Page picture is the only brand mark, so the logo lives inside the creative.
Primary text shows about 125 characters before “See more”; keep headlines near 40.
Demand Gen · Performance Max
Minimum 600 × 314. Max 5 MB, JPG or PNG.
Minimum 300 × 300.
Minimum 480 × 600.
Same safe zones as 9:16 video.
Google builds the ad around your assets: give a square logo (1200 × 1200, under 150 KB) and the business name, and keep images free of overlaid logos, text and buttons.
Headlines 30 characters, long headline 90, descriptions 90.
via Google Ads
Under 10 seconds cannot serve in-stream.
Keep text away from the right rail and the bottom.
Channel name and icon come from the linked channel; an end screen or last frame carries the logo.
Minimum length 5 seconds.
In-feed ads
Minimum 540 × 960. Use TikTok’s safe-zone overlay: the right rail and bottom caption cover the frame.
Accepted; loses most of the screen.
Accepted; rarely the right choice.
Profile image 98 × 98 (key element inside 66 × 66, under 50 KB) and a display name up to 20 characters. Spark Ads use the creator’s profile instead.
Ad text around 100 characters; it renders in TikTok’s own font.
Single image ads
Safest choice on desktop and mobile.
Mobile feed.
The company page logo and name show above every ad automatically.
Intro text truncates around 150 characters; headlines near 70.
Standard pins
Taller pins may be cut off in the feed.
Brand name from the business profile; a small logo on the pin itself helps saves travel.
Titles up to 100 characters; the first 40 carry it.
covered by the app’s interface on 9:16 · Checked 26 Oct 2026 against the platforms’ help pages. Specs change; confirm in Ads Manager before production.
Google assembles the ad from separate assets, Meta shows only the Page picture, TikTok a 98-pixel profile image. Know which one you are feeding before the logo goes into the image.
Google · LinkedIn. Logo, name and headline arrive as separate fields. Keep the image clean: no overlaid logo, text or button, or the ad shows them twice.
Meta · Pinterest. The only brand mark is a small profile picture. The logo, the product and the promise have to live in the image itself.
TikTok · Shorts · Reels. Ads that look like posts win. Brand in the first seconds through product, voice or a short end card, not a fixed corner logo.
A phone viewer decides in about a second. Give the eye one place to land, keep the brand readable and leave room at the edges. Change the frame, the logo position and the margin, and watch the checks.
Eye-tracking work agrees on the basics: faces, contrast and motion are seen first. Pick the one thing that should be seen, and place it on a thirds line.
Keep logo and text at least 4–8% in from every edge. Crops differ by placement, and a logo glued to the border looks like a mistake.
Top-left or top-centre logo, the promise across the middle third, the button bottom-right where the thumb already is. On 9:16, lift it all above the caption zone.
The rest goes in the ad copy. Large type, one weight change, brand colours from the kit, and contrast that survives a dimmed screen.
Put a website into an image model and you get the model’s default taste. Teams getting results wrap the model in research: brand, competitors, a library of winners and a person’s judgement, then feed the test results back.
Website, product pages and reviews: what is sold, to whom, the claims you can prove and the tone of voice.
Logo files, fonts, colours and product shots, taken from the site so every ad stays on brand without a designer checking pixels.
Which formats run today, and how long each ad has stayed live. Ads that survive for weeks are the ones the budget kept paying for.
Public ad libraries show what competitors run and for how long. Long-running formats are the ones worth learning from.
A labelled set of winning ads across industries: format, hook, layout and run time. One team describes about 1,000 of them.
A person rates ads and says why. With hundreds of rated examples (one team rated about 700) the agent stops producing the model’s default look.
All of it becomes one specific instruction: format, layout, copy, brand kit and taste, instead of “here is my website”.
Variants run as a sized test. Results go back into the library, so the next brief starts from what actually won.
The wrapper, not the image model, is the asset. Models get swapped every few months; the brand research, the labelled library and the rated examples stay and get better with every test.
The agent produces the variants. The PME owns the inputs, the test and the verdict.
Which brand inputs are allowed, which claims are off limits, how many variants the budget can judge, and when a winner is a winner. That is the hypothesis-and-verdict system Chapter III teaches.
Back to Chapter IIIThe research-loop pattern and its numbers (about 1,000 reference ads, about 700 rated by hand) follow a workflow shared by practitioner Josh Jackson in a video on building ad-creative agents.
Claude Hopkins treated advertising as salesmanship in print, and every claim as something to test. His Scientific Advertising was locked in a safe for 20 years because it gave away the secrets. Models make the variants now; his rules are still the best instruction you can give them.
Never judge buyers by your own taste. Hopkins made his mistakes small, learned from each, and let public response decide every claim.
For the agentSized tests only. The agent proposes; spend gives the verdict. Your favourite variant gets no extra vote.
It picks the right person out of the crowd, like calling “Hey there, Bill Jones”. Put the main promise in it. Hopkins spent hours on one line and threw scores away.
For the agentGenerate many headlines per idea and test the headline before the visual. The biggest lift is usually there.
Schlitz cleaned every pipe twice a day and filtered the air in its cooling rooms. Every brewer did it; nobody had said it. Makers are too close to their product to see what amazes buyers.
For the agentMine the website, specs and process docs for the dull facts competitors never mention, and turn one into the hook.
“Best in the world” rolls off like water. Real numbers are believed and remembered.
For the agentEvery variant needs one concrete number: time saved, price, results. Ban unprovable superlatives in the brief.
One dramatic demonstration beats any argument. Samples work best when people asked for them and made a small effort.
For the agentOpen on the product in use, before and after, in the first two seconds. Gate the free trial behind one small step.
Boasting and selfishness are the two great faults. “Insist on this brand” and “avoid imitations” kill ads.
For the agentLead with the buyer’s outcome. Cut every sentence that is about the company, not the customer.
People will do anything to cure a trouble and little to prevent it. Pepsodent sold beautiful teeth, never decay, and never pictured the afflicted.
For the agentFrame the gain, not the fear. Show the after-state and attractive results, not the problem.
A woman asking about sewing machines got the sewing-machine catalogue and the names of owners in her town, not the whole range.
For the agentSegment by intent: one ad, one landing page, local or peer proof for each audience the platform finds.
You are not advertising to a standing army but to a moving parade. The ad that won millions usually keeps winning; only the advertiser is bored of it.
For the agentRotate on data, not on boredom. Retire a creative when its numbers fatigue, not when the team does.
Give them to the agent as a gate, and to the person who approves. “Genius is the art of taking pains.”
