OAuth + campaign creator are code-complete but publishing awaits LinkedIn Advertising API (MDP) approval. Knowledge, tips and generation work now; publish surfaces say so honestly.

Every campaign starts from a goal. Each goal maps to one LinkedIn objective with its own optimization events, required setup and learning phase.

LinkedIn has no app-install objective. The engine honestly maps App to WEBSITE_VISIT (store-page traffic). Never presented as an install objective.
Text limits
| Field | Hard max | Recommended |
|---|---|---|
| Headline | 200 chars | ≤ 70 chars |
| Intro text· check docs | 600 chars | ≤ 150 chars |
Headline: 200 is the API cap the draft schema enforces; ~70 chars show before truncation (same threshold the rules engine warns at).
Intro text: ~150 chars show before 'see more' (the engine warns there); re-verify the hard cap per ad format.
Creative specs
Ship the full ratio set per placement. Serving one stretched asset everywhere is penalized by delivery ranking.
Policy rules
Ads may not assert or imply knowledge of personal characteristics (health, finances, group membership). Same discipline as Meta's personal-attributes rule.
Health/pharma, financial services and political ads are restricted per market; recruitment-adjacent claims must not discriminate.
Content must fit a professional context. Sensational or consumer-bait formats are rejected or throttled.
Common mistakes
AND-combining many facets (title + seniority + industry + size) collapses the audience below viable scale; LinkedIn recommends 50k+ members. Pick 2-3 facet types, not all five.
Urgency/scarcity copy that works on Meta reads as spam in a professional feed and hurts relevance.
Most delivery is mobile: check truncation at ~70 (headline) / ~150 (intro) chars, not the desktop render.
Frequent budget/targeting edits keep campaigns from exiting LinkedIn's ramp-up; give changes several days.
Working guidance
Professional and value-led: speak to the role and the buying committee, lead with the business outcome or insight, no clickbait, no consumer-style urgency.
Open the intro with the audience's problem or a specific insight in the first ~150 characters; name the role you serve ('for RevOps leads'). Self-selection beats broad cleverness on LinkedIn.

Leads: B2B lead cost drops meaningfully when a warm layer exists: run Awareness/Engagement to the target profile first, then retarget engagers with the Leads campaign.

Smaller audiences saturate: at typical B2B audience sizes expect fatigue in 4-6 weeks; rotate the angle (insight vs proof vs offer), not just the image.

Awareness: Thought-leadership framing (a claim your buyer would repeat in a meeting) outperforms product-first copy for awareness on LinkedIn.
