Demand Gen vs Demand Capture: What's the Difference?

The 2–4% Problem

At any given time, only 2–4% of your total addressable market is actively looking to buy. The rest — the vast majority — aren't thinking about your category, aren't evaluating solutions, and aren't ready for a sales conversation.

If you only run demand capture (bottom-of-funnel ads asking cold audiences for demos), you're competing for that tiny 2–4% against every other vendor in your space. It's expensive, competitive, and produces diminishing returns as you saturate the in-market pool.

Demand generation works on the other 96%. It builds awareness, educates, establishes trust, and positions your company so that when someone enters the market, your brand is already top of mind. It also generates inbound before you even ask for it — DMs, website visits, direct demo requests — because great content creates demand on its own.

Demand Gen Tactics on LinkedIn

Demand generation on LinkedIn is primarily content delivery through thought leader ads — ads promoted from personal profiles rather than brand pages. The content falls into three buckets:

• Social proof: Client wins, testimonials, case studies. Show the results, not just the features. Include how you achieved the results, not just what they were.
• Product-led: Feature demos, benefit explanations, before/after comparisons, "us vs them" content. Show the product doing real work.
• Problem-led: Teach useful information, solve real problems your ICP faces, create urgency around the status quo. Position yourself as the expert.

Deliver this content to your target account list at the 5×5 minimum — five pieces of content, each seen at least five times. The goal is not clicks or conversions. The goal is awareness, recognition, and trust. Demand gen is measured by penetration rate and frequency, not CPC.

What is demand capture on LinkedIn, and how do you run it?

Demand capture on LinkedIn is the set of conversion campaigns that turn existing buying intent into a meeting, a demo request or a qualified lead — as opposed to demand generation, which creates the intent in the first place. It targets the 2–4% of your market that is in-market right now, and the people your demand gen has already warmed. On LinkedIn that means three formats, one audience rule, and two metrics most advertisers get wrong.

The three capture formats

• Conversation ads with an incentive. A sponsored message from a named sender, offering something concrete — a gift card for a demo, a benchmark report, an audit — with a single call to action. The most effective capture format on LinkedIn for sales-led B2B. SQLs land at $59–$388 depending on how warm the audience is. Measure them on opens and open rate, not clicks; a conversation ad that is opened has done its first job. Setup, bidding and incentive structures are in the conversation ads playbook.
• Single image ads to a lead gen form. The form is pre-filled from the profile, so friction is close to zero — and with the Calendly integration the demo is booked without leaving LinkedIn. The catch is the metric: LinkedIn reports form opens prominently and submissions quietly. Only oneClickLeads — actual submissions — are leads. Opens are not.
• Website conversion campaigns. Single image or document ads driving to a demo page or a high-intent landing page, optimised to a conversion event from the Insight Tag. Slower and dearer per lead than the two above, but every visitor feeds the retargeting pool for the next round. Report on landingPageClicks, never clicks — the latter counts likes and profile views.

The audience rule: capture from warm, not cold

The single biggest determinant of capture cost is who you point it at. The same conversation ad sent to a retargeting pool — people who engaged with a thought leader ad, visited the site, or opened a previous message — costs a fraction of what it costs cold. In our accounts, retargeting audiences produce SQLs at $59–$165; cold audiences run $154–$388. Build capture audiences from:

• Engagement retargeting — anyone who interacted with your thought leader ads in the last 90 or 180 days
• Website retargeting — visitors to pricing, demo and case-study pages
• Uploaded lists — the same account list your demand gen is warming, so both halves run off one dataset

Running capture to a cold audience is the most common way B2B teams conclude "LinkedIn doesn't convert." It converts; it was never warm.

Google Ads alongside

Google captures demand you did not create — people already searching for the category. It belongs in a capture programme if budget allows, but it is increasingly competitive and AI summaries are absorbing clicks, so treat it as an addition to LinkedIn capture rather than the centre. The full channel logic is on our demand generation page.

What "working" looks like

• Conversation ads: open rate above 40% on a warm audience; cost per SQL inside your ACV-justified range
• Lead gen forms: submission rate on opens, not impressions — if opens are high and submissions are low, the offer is wrong
• Website conversions: cost per landing page click and conversion rate on the page, tracked separately
• Across all three: leads by audience source, so the warm-versus-cold gap shows up in your own numbers

Budget Split

A typical budget split is 60% demand gen, 40% demand capture. At £10K per month, that means ~£6K on thought leader ads delivering content, and ~£4K on conversation ads, lead gen forms, and website traffic campaigns.

As your funnel matures and inbound increases, the demand capture portion can scale while demand gen stays relatively stable — your ICP audience size is fixed, so the cost to hit 5×5 doesn't change much. But you can always capture more demand as awareness compounds.
