Refinements applied to this skill:
| Code | Refinement | How it lands in linkedin-ads-copy |
|---|---|---|
| R1 | Source placement | Ad copy is end-customer-facing. No source tags. |
| R3 | Product-update tone | Intro text + headlines frame as "[Product] does X" not "thrilled to introduce." |
| R5 | Blog as voice anchor | Anchor blog opener = intro text first line across funnel stages. |
| R6 | CTA hierarchy | Awareness → blog/learn-more. Consideration → sign-up + blog as fallback. Conversion → trial primary. |
| R9 | Action-oriented section names | Intro / Headline / Description verb-led, no "About us" copy patterns. |
Triggers
Run this skill when:
- Paid-campaign-strategy is locked and the next step is generating ad-set copy
- A client wants TOFU/MOFU/BOFU LinkedIn coverage built out across formats
- Existing LinkedIn campaigns need refreshed copy (e.g., low CTR, format expansion)
- ABM targeting needs accompanying ad copy with variant breakdowns
Do NOT run when:
- Strategy isn't locked — run
/paid-campaign-strategyfirst - Target channel is Google search/display — use
/google-ads-copy - The ask is a single LinkedIn organic post — use
/linkedin-contentor/linkedin-hooks
The Iron Law — voice-locked
EVERY CHARACTER COUNT MUST BE VERIFIED.
LinkedIn will truncate or reject copy that exceeds format limits. There is no "close enough." Count every character including spaces, punctuation, and emojis.
No exceptions:
- "It's only 1 character over" → LinkedIn truncates it. Trim it.
- "The visible limit is 150 but max is 600" → Users see 150. Write for 150. Use 600 only when expanding is worth it.
- "Carousel headline limit is 70 chars" → It's 45 with a link. Know which format you're writing for.
- "We can just shorten the CTA" → Conversation Ad CTAs are ≤20 chars. Spotlight CTAs are ≤18 chars. Different formats, different limits.
Funnel-stage discipline — voice-locked
| Stage | Voice | What's allowed | What's banned |
|---|---|---|---|
| TOFU | Educational, not sales-y | Insight hooks, soft CTAs, thought leader format | Product names in intro, hard sell, demo CTAs |
| MOFU | Product education | Feature spotlights, before/after, named proof | Generic awareness copy, missing CTA |
| BOFU | Conversion drivers | Single direct CTA, de-risking language, social proof | Multiple CTAs, soft hooks, vague offer |
| Retargeting | Closing language | Urgency, social proof, direct CTA | New-to-brand intros (audience already engaged) |
Hooks must be genuinely distinct across the three variants — different angles (stat / contrarian / question / proof / before-after), not synonym swaps.
Targeting invariants — voice-locked
- Skills-only > title+skills > title-AND-skills. Title AND skill in separate facet groups shrinks the audience 60-80% silently. Default to skills + seniority + function in the same group for ABM.
- Audience-size bands match funnel stage. TOFU 30-150K, MOFU 10-50K, BOFU 5-30K. If your numbers are off-band, the layering is wrong.
- Competitive displacement is MOFU/BOFU only. Listing competitor products as skill targets at TOFU reads as aggressive and tanks engagement.
- Insight Tag required for retargeting. No tag = no retargeting audience. Confirm before recommending it.

| competitor-research | For competitive displacement campaigns | Optional |
| brand-kit + tov-guidelines | Voice + visual constraints | Recommended |
Process
Four-phase flow: Funnel-stage selection → Copy generation (3 variants per ad, character verification) → Targeting + budget mapping → Verification + structured output. Full flowchart, ad-format spec table, hook patterns per stage, targeting AND/OR logic, and competitive displacement playbook in the premium reference.
Anti-Hallucination Guardrails
- Never invent metrics or customer names. If proof isn't in product-messaging or messaging library, mark
[NOT AVAILABLE]and omit. - Don't approximate character counts. Count every variant before output.
- Don't recommend bid strategies the client can't run. Manual bidding requires Campaign Manager access; flag if unavailable.
- Don't fabricate skill IDs for competitive displacement. If you don't have the verified LinkedIn skill ID, name the skill in plain text and flag for the client to verify in Campaign Manager.
- Audience-size estimates are estimates. Always note "approximate" — LinkedIn forecasts shift based on time of day and recent activity.
Quality
Self-evaluation checklist (character compliance, variant distinctiveness, funnel logic, voice rules), anti-examples (close-enough char counts, paraphrase variants, TOFU with hard CTA, title-AND-skill targeting), failure-mode triage (low CTR / CPC spikes / under-performing carousels) in the premium reference.

Final ship gate
Run /premortem --output before ship. See /premortem skill for the 5 execution domains (will-it-resonate / will-it-convert / will-it-stay-on-brand / will-stakeholder-push-back / will-it-degrade-over-time) and output template.
Trivial-case escape: ## Premortem\nNo failure modes — trivial change satisfies the contract for genuinely trivial outputs.
Persuasion & stickiness pass
Output complies with persuasion-and-stickiness.md — Cialdini's 7 persuasion levers + Heath's SUCCESs. Deploy the 1-2 Cialdini levers that fit the reader's barrier (never all seven; every lever must be TRUE), run the SUCCESs diagnostic (Simple / Unexpected / Concrete / Credible / Emotional / Stories) over the near-final draft, then the rule's pre-ship gate.
