A LinkedIn document ad is a sponsored post that lets people read a multi-page PDF directly inside the feed, page by page, without leaving LinkedIn or clicking through to a landing page.
Document ads are a LinkedIn Ads format that renders an uploaded PDF, DOCX or PPT file as a swipeable in-feed document. The viewer scrolls through the pages inside the feed. You can either let them read the whole thing for free, or gate it after a set number of pages behind a lead gen form.
The format matters because it removes the landing page from the conversion path. Nothing loads, nothing bounces, and the value is visible before the buyer decides whether to give up their details.
[table]
Element | Specification
File types | PDF, DOC, DOCX, PPT, PPTX
Maximum pages | 300, though 5 to 12 is where performance lives
Maximum file size | 100 MB
Orientation | Vertical, horizontal or square. Vertical wins on mobile
Gating | Optional. Gate after 1 to 3 pages, or leave fully ungated
Headline | 70 characters before truncation
Intro text | 150 characters before the "see more" cut
Objectives | Brand awareness, engagement, website visits, lead generation
Where it runs | LinkedIn feed only. Not on the Audience Network
[/table]
The practical constraint is page count. A 40-page report gets three page-flips of attention. Five to twelve pages, each carrying one idea, is where the format performs.
Ungated. The full document is readable in the feed. You capture no leads and no email addresses. What you get is depth of attention from named accounts, and LinkedIn reports how many pages each viewer read. Run this when the goal is demand creation and the audience is cold.
Gated after page two or three. The reader sees enough to want the rest, then hits a lead gen form pre-filled with their LinkedIn profile data. Conversion rates on this are consistently strong because the form is native and the value has already been demonstrated.
Most accounts should run both. Ungated to cold audiences to build familiarity, gated to the retargeting pool of people who already read pages of an ungated document.
Attention, not clicks. That is the whole reason the format exists.
A standard single-image ad gives you one impression and a click-through rate. A document ad gives you page-level engagement data on a cold audience, which tells you something no other LinkedIn format does: whether the people at your target accounts found the argument compelling enough to keep reading.
That data is also the highest-quality retargeting signal available on the platform. Someone who read seven pages of your teardown is a materially warmer audience than someone who clicked a link and bounced. Building a retargeting audience on document engagement, rather than on website visits, is one of the few genuinely underused mechanics in B2B LinkedIn advertising.
Two reasons cover most of it.
The document is a repurposed sales deck. Company slide, problem slide, solution slide, logos, book a demo. Nobody reads a sales deck in their feed. The documents that work teach something specific and complete: a teardown of a real campaign, a benchmark set, a framework with numbers attached. If the reader gains nothing by page three, they leave and you have paid $30 CPM for a bounce.
It is gated on page one. Gating before any value is delivered turns the format back into a standard lead gen ad, with the extra friction of a document that never got read. Give away pages two and three. The gate works because the reader already knows what they are trading their email for.
Use document ads to earn attention from cold accounts, not to collect emails from warm ones.
The sequence that works: run an ungated, genuinely useful document to a cold firmographic audience. Build a retargeting audience from everyone who read three or more pages. Serve that audience a gated document, a case study or a direct offer.
Judge the ungated stage on pages read and retargeting pool growth, not on leads. Judge the gated stage on cost per SQL, not cost per lead. Applying lead-capture benchmarks to the demand creation stage is the single most common reason a working document ad strategy gets switched off in month two.
Document ads carry a high CPM by any standard. They earn it only when the document is worth reading. There is no targeting fix for a boring PDF.
Upload a PDF, DOC, DOCX, PPT or PPTX file up to 100 MB and 300 pages. Vertical orientation performs best on mobile. Keep the headline under 70 characters and the intro text under 150 so neither gets truncated in the feed.
Both, at different stages. Run ungated documents to cold audiences to build familiarity and generate page-level engagement data. Run gated documents, with the form appearing after page two or three, to people who already engaged with the ungated version.
Five to twelve. LinkedIn permits 300, but attention drops sharply after the first few page-flips. One clear idea per page beats a dense report every time, and shorter documents produce higher completion rates and better retargeting pools.
Carousel ads are a series of images, each with its own link and destination. Document ads render an actual file as readable pages inside the feed and report how far each viewer read. Carousels drive clicks out; documents hold attention in.
Yes. LinkedIn lets you build a matched audience from people who viewed a set percentage of the document, typically 25%, 50%, 75% or 100%. This is far more precise than website retargeting because it measures actual reading depth rather than a single page load.

If your document ads are producing readers but not pipeline, the gap is usually in what happens after page three, not in the targeting.
