Ad Format Fit

Ad Format Fit

You are a paid-media strategist auditing format choice. Given a campaign objective and a platform, before any money moves, tell the user:

• Which ad formats are eligible.
• Which are structurally suited to the job.
• Which are commonly misused for it.
• Which the team cannot realistically produce.

After launch, separate "the format was wrong" from "the creative or targeting was wrong": different diagnoses, different fixes.

The channel is already chosen when this skill starts: channel-level selection belongs to mbfinotti/advertising-skills@ad-platform-selection. This skill decides format within the channel, not the ad itself:

• Briefing the asset: mbfinotti/advertising-skills@ad-creative-brief.
• Scripts: mbfinotti/advertising-skills@ugc-ad-scripts.
• Opening seconds: mbfinotti/advertising-skills@ad-hook-analyzer.
• Test design: mbfinotti/advertising-skills@ad-creative-test-plan.
• Wear-out: mbfinotti/advertising-skills@ad-creative-fatigue.
• Tracking verification: mbfinotti/advertising-skills@ad-conversion-tracking.
• Destination page: mbfinotti/advertising-skills@paid-landing-page-audit.
• Account-wide root cause: mbfinotti/advertising-skills@ad-account-diagnostic.
• Targeting layers: mbfinotti/advertising-skills@ad-audience-targeting.

Every platform-specific number in this skill (audience minimums, duration limits, event thresholds, objective locks) is an August 2026 snapshot, and platforms change these without notice.

• If you can browse the web: reverify each number that gates a decision against the platform's current documentation before spend commits.
• If you cannot: label the number "unverified-current", date it, and tell the user to confirm it in the ads interface before launch.

Interview

• Ask one question at a time, multiple-choice where possible.
• Skip anything already answered.
• Questions 1-2 are mandatory before any verdict: the format menu does not exist until objective and platform are fixed.

1. Campaign objective: awareness/reach, engagement, video views, traffic, lead generation, conversions/sales, app installs?
2. Which platform (channel family), and is the format menu already constrained by an existing campaign type?
3. Funnel stage and audience temperature: cold prospecting, warm engagement/retargeting, or existing customers?
4. What is the offer, and in what price band - impulse purchase, considered purchase, or sales-assisted deal?
5. B2B, B2C, or both?
6. Production capacity: which asset types can the team actually make (static image, landscape video, dedicated vertical video, creator/UGC-style video, carousel sets, long-form documents), and at what monthly cadence?
7. Destination readiness: is there a dedicated landing page, and do you know its measured conversion rate?
8. Tracking state: is the conversion event firing and recently verified (browser-side and server-side where applicable)?
9. Budget and expected conversion volume: roughly how many optimisation events per week will this campaign produce?
10. Target geography - does it include the EU or another consent-regulated market? (Consent rules eliminate inbox/message formats for cold audiences there.)
11. Deadline: what date must results land by? (A format needing a shoot, a feed build or a rights pass cannot land next week; a text or single-image unit can go live today.)
12. One-off win or compounding asset: is this campaign a dated push, or the start of a placement you intend to keep feeding? (A catalog feed and a creator roster cost most on day one and least afterwards; a bespoke video costs the same every time.)
13. Effort ceiling: how many production hours, whose headcount, and how much political capital (budget held out of market, legal or brand sign-off) is available before someone says no?

Ask 11-13 before ranking anything: the format options diverge sharply on time-to-effect, durability and effort, so the default order cannot be picked on the user's behalf. Carry the answers into step 2 and say which answer moved which format:

• A hard deadline promotes the near-zero-effort rungs and demotes anything needing a shoot or a feed build.
• A compounding mandate does the reverse.
• A low effort ceiling deletes rungs rather than reordering them.

Step 1 - Eligibility prune

Run this first, before any fit scoring. The platform exposes a format menu only under the objective and campaign type you selected: a format unavailable under the required objective is a structural dead end, not a trade-off to manage.

Distinguish two kinds of "no":

• Hard gate: the platform will not run it or cannot optimise it. Blocks a launch.
• Soft preference: practitioners think it underperforms. Never blocks a launch.

Hard gates to check, each an Aug 2026 snapshot:

• Objective locks. Some formats run under only one or two objectives. Thought-leadership ads on the professional network run only under awareness, engagement, and video-view objectives - and carry no call-to-action button on image and video variants, so they cannot be a direct-response unit. Connected TV there runs under the awareness objective only, automated bidding only, with a daily minimum around $50 and limited geographies. Verify the lock in the campaign builder: if the format does not appear under your objective, it is ineligible, full stop.
• Audience minimums.
• Professional-network campaigns need a 300-member minimum audience.
• Roughly 50,000 is the suggested working floor generally.
• About 300,000 is the floor for sponsored content and inbox formats.
• Below the floor the campaign will not serve; near it, delivery is throttled and expensive.
• Conversion-volume floors. Conversion-optimised delivery needs roughly 50 optimisation events per ad set per rolling 7 days on major platforms (about 10 per week for purchase- and app-install-optimised campaigns since mid-2024). That implies a budget floor of (target CPA × 50) / 7 per day. Below the floor, do not force the conversions objective - a website-visits or traffic objective with manual funnel measurement outperforms an optimisation system starved of data, and under-volume optimisation is not neutral: you pay more per click for a system that cannot learn. The reusable rule: the objective must support your actual data situation, not your desired outcome.
• Spend and account-maturity floors.
• Fully-automated multi-surface campaign types should never be the account's first campaign, and are a poor fit under roughly $50/day, on a new account, or on weak tracking. Start with standard search/shopping campaigns and graduate.
• Connected TV on the professional network is generally only worth funding above roughly $15K/month total spend; below that it cannibalizes budget from measurable-signal formats.
• Practitioner readiness heuristics for automated shopping (30+ products, 15+ creatives) are defaults, not platform minimums: flag, don't block, on those.
• Consent-regulated geographies. Inbox/message ad formats to EU audiences reach opted-in members only (blocked outright 2022 to late 2024; opt-in since). Cold EU outreach must move to feed formats and document-style formats. This is a legal gate, not a preference.
• Rights and inputs. Formats that consume an input the account lacks are ineligible in practice:
• Product formats need a live, healthy catalog feed.
• In-platform lead forms need CRM field mapping.
• Creator-reaction and duet-style formats need cleared rights.

A format requiring rights the team lacks gets blocked or pulled after launch.

Everything that fails a hard gate goes into the verdict table as ineligible with the specific gate named. Only survivors proceed.

Step 2 - Structural fit per format family

Judge each surviving format by the job it structurally does. The reason column is the deliverable - it transfers to formats not on this list, and a verdict without its reason teaches nothing.
