Document Ads vs LinkedIn Single Image Ads

In short: Both are Sponsored Content that can carry a lead gen form and run from a company page. The split is what happens after the scroll stops: a single image sends people off to a landing page or form immediately, while a document ad lets them read the actual content, page by page, inline in the feed before any form appears. Document ads succeed or fail on whether the content itself holds attention; single image ads succeed or fail on whether the headline earns the click. If the offer is the content itself - a guide, report, or checklist - use document ads; if the offer lives on a page you're driving traffic to, use single image.

Document Ads

Delivers a PDF that readers page through directly in the LinkedIn feed, optionally gating later pages behind a lead form.

The document previews inline, so a report or checklist gets consumed without leaving the feed, and you can require a lead form before the remaining pages unlock. It is a natural fit for B2B content offers that would otherwise sit behind a landing page. The mistake is gating too early, or uploading a dense whitepaper, since pages are read on phones and must prove value fast.

LinkedIn Single Image Ads

One static image with intro text and a headline, running in the LinkedIn feed as a sponsored post from a company page.

It publishes through a company page and appears between organic updates, carrying a call-to-action button and a link or lead form. Most B2B programs start here because production is quick and the reporting is straightforward. The recurring mistake is writing it like a display banner: the LinkedIn feed rewards specific, plain intro copy that names the audience and the problem, not slogans layered over stock photography.

Side by side.

The differences that actually change what happens in your account.

	Document Ads	LinkedIn Single Image Ads
What lives in the feed	The actual PDF pages, swipeable and readable without leaving LinkedIn.	One image and headline that link out to wherever the offer is hosted.
Where the lead form sits	Optionally gates later pages of the document, appearing mid-consumption.	Reached only after the click, before any content is shown.
What you're really testing	Whether the content is good enough that people opt in partway through reading it.	Whether the image and headline earn a click at all.
Content requirement	An actual document asset - a guide, report, checklist, or deck built for on-feed reading.	One image and a short line of copy, no separate content asset required.
Drop-off point	Happens mid-document, at the gate or wherever interest fades.	Happens at the click - the image and headline either earn it or they don't.
Best measured by	Page-level read-through and completion, then form fill rate on top.	Click-through rate and post-click conversion on the landing page.
Mobile reading experience	Pages must be built for phone-sized reading, not a print whitepaper shrunk down.	One image renders the same regardless of formatting choices made for print.

What actually separates them.

Document Ads let a prospect consume the actual offer inside the feed before converting, while Single Image Ads always require a click off-platform first to see what's being offered.

The lead form in a Document Ad can sit mid-content, gating only the later pages, while a Single Image Ad's form or landing page gates the entire offer from the first click.

Document Ads succeed or fail on whether the content itself holds attention page by page, while Single Image Ads succeed or fail on whether one headline and image earn the click.

Building a Document Ad means producing and formatting a readable asset, while building a Single Image Ad means writing a headline and picking or making one image.

Document read-through gives you a mid-funnel quality signal - how far people got before dropping - that a Single Image Ad's click-only reporting can't produce.

Which one should you use?

Use Document Ads when

The offer is a piece of content itself - a report, template, checklist, or slide deck - not a product page.
You want people to experience some value before you ask for their email, rather than gating a landing page on the first click.
You're repurposing an existing PDF asset and want distribution without building a separate landing page.
You want a read-through signal to tell you whether the content is actually good, not just whether the thumbnail got clicks.

Use LinkedIn Single Image Ads when

The destination is a product, service, or signup page that needs its own dedicated experience.
You want the fastest, lowest-production Sponsored Content format to test a message.
The offer doesn't reduce to a document - it's a demo, a free trial, a booked call.
You need clean click and landing-page conversion reporting without a content-consumption step in the middle.

Common questions.

Should I gate the first page of a Document Ad?

No - gating too early is the most common way to kill a Document Ad's performance. Let readers get far enough in to trust the content before the form appears, since the whole advantage of the format is proving value before asking for information.

Can a Document Ad replace a landing page entirely?

For content offers, largely yes - the document itself becomes the landing experience and the form captures the lead inline. For anything that needs a demo booking, pricing, or a product walkthrough, you still need an actual page to send people to.

Why is my Document Ad getting clicks but few form fills?

That usually means the document isn't proving its value fast enough before the gate, or the gate is placed too early relative to how long people actually read. Check where in the document engagement drops off and either move the gate past that point or tighten the opening pages.

Or stop choosing between them.
