Document Ads

What are Document Ads?

Document Ads are a LinkedIn ad format that puts a document in the feed. People can scroll through the pages right inside LinkedIn, then download it. You choose whether they get the whole thing for free or see a preview and fill in a Lead Gen Form to get the rest.

Let's say you sell incident response software. Your team writes a 20-page checklist for the first 24 hours after a breach. You run it as a Document Ad aimed at security leads at companies with 200 to 2,000 people. The first four pages show in the feed: the cover, the contents and the first two steps. To see the other 16 pages, a reader taps through to a form that's already filled in from their LinkedIn profile, and the full checklist then arrives in their LinkedIn inbox.

LinkedIn's getting started guide says you can upload PDF, DOC, DOCX, PPT or PPTX files up to 100MB and 300 pages.

Why Document Ads matter for B2B SaaS

Most B2B ads ask for a click to a landing page, and most people don't click. A Document Ad lets them read the useful part without leaving the feed, so you get attention even from people who never fill in a form.

They can also be cheap leads. Metadata's 2025 data on B2B advertisers put Document Ads at $142 per lead, the lowest of any LinkedIn format it tracked, against $200 for single image ads. We covered more channel numbers in our post on cost per lead by industry.

Here's why I'd test them early:

• They show your expertise up front: A buyer can judge your thinking from the first few pages. That's a better first impression than a headline and a stock photo.
• Lead forms fill themselves: LinkedIn fills in name, title and company from the profile, so people only have to tap submit. That's much less work than a landing page form on a phone.
• They feed retargeting: LinkedIn lets you build an audience of people who engaged with a Document Ad. You can show those readers a case study or a demo offer next.

How to run Document Ads

The format is simple to set up. The work is in picking the right document. Here's my process:

• Pick an asset buyers would pay for: Original benchmark data, a template your customers use or a checklist from your own team's work. If it's a rewritten blog post, people stop after page two.
• Design for a phone: Most people read on mobile, so use big type, one idea per page and short lines. A slide deck exported as a PDF often works better than a long report layout.
• Put real value in the preview: Show the cover, the contents and at least one full useful page before the gate. People fill in the form when the preview proves the rest is worth it.
• Decide the gate on purpose: Gate the deep assets and leave quick guides open for reach. You can run the same document both ways in two campaigns and compare cost per meeting.
• Keep the form short: Ask for what sales really uses, like name, work email, title and company. Every extra question lowers the share of people who submit.
• Follow up fast and kindly: Send leads to your CRM the same day. A useful follow-up email about the topic does better than a rep asking for a call in the first hour.

A Document Ads example

Webflow is a real example of content downloads working on LinkedIn. In its LinkedIn customer story, Webflow said ads promoting content downloads did better with enterprise audiences than ads about product releases, and it reported a 425% year over year increase in MQLs. Our guide to LinkedIn marketing for B2B SaaS covers how it fits with the rest of a LinkedIn plan.

Here's a hypothetical test plan for the incident response checklist above:

After a month, you compare cost per meeting across all three. You'd expect the open version to build the bigger retargeting pool and the gated one to bring more names for sales. The test tells you which one matters more for your pipeline.

How to measure Document Ads

LinkedIn Campaign Manager reports how much of the document people read and how many downloaded it, next to the usual clicks and leads. Here's what I track:

• Read depth: Look at the share of viewers who get through 25%, 50% and 75% of the document. A big drop after page two means the content or design needs work.
• Lead form completion rate: Divide form submissions by form opens. If people open the form and leave, ask for fewer fields.
• Cost per lead and per meeting: Pull spend from Campaign Manager and meetings from your CRM. A low CPL only counts if the leads book calls.
• Lead fit: Check what share of leads match your ICP by title, company size and industry. LinkedIn targeting helps, but it doesn't guarantee fit.
• Pipeline from readers: Track opportunities from accounts whose people read the document, even if they never filled in the form. Retargeting and sales outreach often turn those readers into deals later.

Common Document Ads mistakes

• Gating a thin asset: A five-page ebook behind a form gets few leads and annoys the ones you get. Gate only what's worth trading an email for.
• Using a print layout: A report designed for A4 paper is hard to read on a phone in the feed. Rework the pages for small screens before you upload.
• Showing too little in the preview: A cover page and a contents page don't prove anything. Let people read at least one page that teaches them something.
• Handing every download to sales: Many readers just wanted the checklist. Nurture them with useful follow-ups and pass on the ones who show buying signals.
• Leaving the document stale: A 2024 benchmark in a 2026 campaign hurts trust. Update the data or swap the asset when it ages.

Here's a first step. Look at your best performing piece of content from the last year and ask whether a buyer would read four pages of it on their phone. Would they want the rest?
