- Up to 5 CTA buttons (1 is the mandatory "Not Interested" - so 4 custom CTAs max).
- Branching decision tree supported (follow-up messages based on which CTA is clicked).
- Optional companion banner: 300x250 px (desktop only), JPG/PNG, max 2 MB.
- Can attach a Lead Gen Form (one per conversation).
When to Use Conversation Ads vs Message Ads
Conversation Ads (choose-your-own-adventure, multiple CTA paths):
- Complex B2B buying journeys with multiple stakeholders
- Buyers who want to explore before committing
- ABM or high-intent campaigns
- Goal is to educate, qualify, and learn - not push immediate action
- When you want intent signals (every click tells you what the buyer cares about)
Message Ads (single message, single CTA):
- One clear goal (book a demo, download a guide)
- Quick, direct, cost-effective outreach
- Audience prefers short, no-nonsense messaging
- When you need simple, single-action conversions or low CPL
Key distinction: Message Ads talk to people. Conversation Ads speak with them. Conversation Ads are not built for instant wins - they influence interest over time.
Copy Principles
- Write like a text, not a landing page. Conversation ads go to an inbox. Short, casual, human. If it feels like a sales pitch, it's wrong.
- Keep messages to 3-5 short lines. One idea per line. Product features, bullet lists, and detailed specs belong on the landing page or in the lead magnet - NOT in the message. One of the best-performing ads ever was "Hey, want to chat?"
- No more than 3 lines before a paragraph break. Big blocks of text = reader scans and opts out. Force slow reading with frequent breaks.
- One sentence per line. Makes the message scannable and easy to consume.
- Subject line: 2-4 words. It's an inbox message - short subjects feel real, long ones scream ad. The first 50 characters of the opening message text also matter as preview.
- Be specific, not vague. Use concrete numbers, timeframes, or outcomes. "29 mins and $105 gift card" > "a quick chat." Shock timing works - specific numbers force consumption.
- Emojis work in B2B (but match the brand). Use directionally (pointing to CTA) and psychologically (associating words with outcomes). Skip emojis entirely if the brand voice doesn't use them.
- Don't be overly conversational either. Be clear about the offer and the value. Tone can match the brand, but clarity > cleverness.
- Avoid buzzwords. Words like "AI-powered," "optimize," "streamline," "game-changer" - buyers mentally skip them. Use specific problems, concrete outcomes, relatable frustrations. Specific beats impressive, every time.
- No feature dumps in the message. The message's job is to earn the click. The details live behind the CTA buttons - on the demo page, in the lead magnet, or in a branch message. Don't try to sell in the inbox.
CTA Strategy
- Clear CTA with a button. Don't bury the action in text. Bad: "Would love to chat if you're interested." Good: "Book a 15-min demo" or "See the case study."
- Skip Action > Call to Action. A Skip Action skips a step in the sales process (e.g., direct scheduling link instead of "fill out a form and we'll follow up"). Drastically improves pipeline efficiency by increasing form-to-demo attendance rate.
- Don't pitch a 1:1 upfront if the goal is registration/download. Match the CTA to the actual goal - don't over-ask.
- Best-performing first CTAs are gentle, not aggressive. "See how it works," "Find out more," "Get started for free" outperform "Book a Demo" as first step. Early-funnel CTAs reduce pressure, invite curiosity instead of commitment, feel helpful not transactional. Think of CTAs as doors, not demands.
- Offer multiple response options, not dead ends. Let the buyer choose their path - content, FAQ, demo, pricing, "just browsing." Every click reveals intent.
Psychology Triggers
Best conversation ads tap into basic human psychology. Common triggers:
- FOMO - "See what top teams are doing differently."
- Curiosity - "Want to know how this works?"
- Reciprocity - "Get the report, no strings attached."
Strongest ads combine two triggers (e.g., curiosity + social proof, reciprocity + urgency, FOMO + data-backed claims). Don't manipulate - if the problem is real, people will lean in.
Sender Profile
- Send from a founder, CEO, VP, or Director - not SDRs or junior reps. Trust and credibility matter. Messages come from real people.
- Personalization starts with targeting, not copy. Great copy cannot save bad targeting. Layer: job title + function, seniority, skills/expertise tied to the problem, location (when buying behavior differs by region). If targeting is off, the "personal" illusion breaks instantly.
- Use someone the audience can relate to. If you're targeting marketers, send from a marketer. If you're the founder and you're customer zero, send from yourself. Use sellers only if there's been prior interaction or they're seen as experts.
- Profile headline needs to sell. Bad: "Sales at [Company]." Good: "$XXM+ in pipeline driven through LinkedIn Ads."
Testing & Benchmarks
- Open rates: Aim for 35-50%+
- CTR: Expect 2-5%
- CPC: $0.30-$0.45
- Budget: Start with $2-3K
- Volume is limited. You won't send 10K messages in a week unless you have multiple senders.
- Test subject lines, CTAs, sender profiles, and messaging. Don't just test delivery - test the copy. Ask: "Would I click this CTA?" and "Does this feel like it's from a real person?"
- Launch timing must match volume. Start 2+ weeks before event/deadline with 1 sender. Shorter windows require multiple senders.
Strategy: TLA + Conversation Ads Combo
A core workflow that works even when you have great creative/video.
- Step 1: Founder/CEO posts on their profile - product releases, industry insights, customer wins, workflows. Simple talking head video on mobile if possible.
- Step 2: Promote those posts with Thought Leader Ads (TLAs) to the target audience. Ensure Campaign Manager is set up correctly - deactivate audience expansion, location auto-expansion, automated bidding.
- Step 3: Retarget people who engaged with the TLAs (or watched 50%+ of video) with Conversation Ads. The convo ad message should relate to the original TLA content.
Why it works: Low-effort, quick to launch, uses just copy (no polished creative needed), and the retargeting warm-up means convo ads land with people who already have some familiarity.
Measurement & Attribution
- Don't measure conversation ads by last-click alone. They rarely drive a straight line from click to conversion. They influence interest over time - content views, return visits, assisted conversions across channels.
- The real value is intent signals. Every click inside the conversation tells you what the buyer cares about - are they curious, researching, or close to buying? That's more valuable than a single "Submit" button.
- Downstream actions matter: website visits, content reads, return visits, assisted conversions - not just form fills. If you only measure clicks, CPL, and last-touch conversions, you're missing most of the story.
- Open rates are high but don't tell the full story. Judge by interaction metrics (which options clicked, what content engaged with next, whether they return later).
High-Performing Message Structure: The Walkthrough Format
Proven structure for demo-oriented conversation ads:
- Open with the pain - 1-2 lines stating the specific problem the audience faces
- Name the product as the solution - 1 line, don't explain everything yet
- "In a 20-minute walkthrough, I can show you:" - frame the demo as a learning session, not a sales call
- 3 specific bullets - what they'll see/learn in the walkthrough. Be concrete, not vague.
- Personalized close - "Want to see if it's relevant for %COMPANYNAME%?"
- Casual CTAs - "Yes, let's do it" / "Tell me more first" / "Not interested"
Why this works:
- Frames the meeting as value exchange, not a sales pitch
- "Walkthrough" feels educational, "demo" feels transactional
- The 3 bullets give the prospect a reason to say yes - they know what they'll get
- %COMPANYNAME% personalization makes it feel targeted, not mass-sent
- Casual CTAs ("Yes, let's do it") outperform formal ones ("Book a demo") because they feel like a text, not a form
CTA best practices for this format:
- Primary CTA goes to a Lead Gen Form, not a scheduling link - reduces friction
- "Tell me more first" branch is where product USPs and social proof live - only shown to people who ask
- Never use "Book a demo" as a CTA label - too sales-y. Use action language: "Yes, let's do it", "Yes, show me", "Let's book it"
Key principle: USPs belong in the message
Don't just state the problem and say "we handle it." Include at least one specific differentiator in the opening message that makes the prospect think "that's different." The branch messages layer in additional USPs for people who want more detail before committing.
Common Mistakes to Avoid
- Treating conversation ads like regular ads (they're inbox messages, not feed ads)
- Making them sound like a bot
- Making them too long and spammy
- Failing to test messaging
- Sending from SDRs or generic sales profiles
- Vague messaging - "I'd love to connect" with no clear value
- Using big blocks of text with no paragraph breaks
- Burying CTAs in copy instead of using buttons
- Only measuring clicks/CPL/last-touch - missing downstream influence
- Using buzzwords instead of specific, concrete language
- Generic, overused, or overly sales-driven messaging - buyers are quick to ignore templates
- Expecting instant conversions - conversation ads are for journeys that take time
