Right now, some of your potential clients don’t know you exist. Others don’t know they are dealing with a problem your product can solve. Some don’t even know they have a problem in the first place. And if you try to sell to them today, they will scroll past the ads.

With LinkedIn document ads, you can make a positive first impression. You educate your audience with valuable content to help them understand the challenges they are facing and how to solve them. With time, they learn to trust your brand, and when they are ready to buy, they will remember you as the expert.

And the best part is you already have the resources. All those blogs, ebooks, benchmark reports, and case studies you spent a lot of time writing are your most valuable assets. Instead of letting them sit idly on your website waiting to be discovered, share them on LinkedIn with your audience.

The mistake many marketers make is expecting document ads to generate leads immediately. We’ve seen marketers kill document ad campaigns because of low CTR and spend more on other LinkedIn ad formats that get high clicks, probably from the wrong audience. But what they don’t understand is that document ads are great for building demand.

In this article, we will cover everything you need to know about LinkedIn document ads, including examples, when to use them, how to measure performance, and how they compare to single image ads (marketers’ favorite).

What Are LinkedIn Document Ads?

LinkedIn document ads are a type of Sponsored Content that allows advertisers to promote documents (case studies, benchmark reports, or blogs) directly within the LinkedIn feed. This lets the audience read and download the content without leaving LinkedIn. That in-feed experience is what sets it apart from other formats like single image ads.

With document ads, you can:

• Build trust with your audience through educational content that helps them solve problems and makes them feel seen. When your content helps, your brand becomes memorable.
• Understand your audience’s interests better by looking at how much of your document is read and downloaded. This information comes in handy when building retargeting campaigns.
• Capture quality leads by gating the content with LinkedIn Lead Gen Forms.

Pushing a demo too early on LinkedIn can be tough, but getting someone to engage with high-value content is a much lower-friction step that many B2B buyers are willing to take.

Gated vs Ungated LinkedIn Document Ads

Document ads can be gated or ungated. With gated content, readers must complete a Lead Gen Form before accessing the full document. But with ungated content, users can read and download the content without filling out forms.

The choice between the two depends on what you hope to achieve. Do you want more reach or more leads? If you want to build brand awareness and boost engagement, then ungated content is the better option. But if you want to capture quality leads, use gated content.

Ungated content also works best for TOFU audiences. These are cold audiences who have no reason to trust you with their personal information. Use educational content like blogs to build their trust before asking them to fill out forms.

Gated document ads, on the other hand, are more suitable for MOFU and BOFU campaigns. These are audiences who already know who you are and may be open to filling out forms. Nurture them with content they cannot get anywhere else, like benchmark reports, ABM playbooks, and pricing guides.

If you are not sure whether to gate or ungate your documents, you can experiment with both. Start with gated content and see if the target audience is willing to give their information for it. The form fills should generate quality leads. But if the lead volume is low, you can switch the document to ungated to increase organic reach.

LinkedIn Document Ads Specs and Requirements

Ad specs

• Supported file formats: PDF, DOC, DOCX, PPT, and PPTX (PDFs are recommended). Users download the document as a PDF regardless of the original format, and converting other formats into PDFs affects the quality of the original doc.
• Maximum file size: 100 MB
• Page limit: Keep it under 10 pages, even though the maximum is 300 pages or 1 million words.
• Aspect ratio: Vertical, horizontal, and square
• Supported PDF layouts: Letter, Tabloid, Legal, Statement, Executive, Folio, A3, A4, B4, and B5
• Campaign objectives: Limited to Brand Awareness, Engagement, and Lead Generation
• Intro text: 150 characters recommended (3,000 characters maximum)
• Headline: Keep it to 70 characters to avoid truncation (200 characters maximum)

Technical requirements

• Minimize the number of PDF layers, as PDFs with multiple layers don’t perform well. Always flatten layered PDFs.
• All pages should be the same size within the document.
• Avoid using CTAs or links within the document. They only function once a reader downloads the document.
• Use images and graphics instead of videos and animations. Videos and animations are not supported.

Anatomy of a High-Performing LinkedIn Document Ad

Here are some tips you can use to give users a better experience with your document ads:

Clear introductory text

The introductory text gives readers a brief overview of what the document is all about and why they should read it. Be very clear on the insights they will get from the document to make them want to know more. For example:

LinkedIn recommends keeping intro text at 150 characters or fewer, as anything past that is truncated on most devices. If you go over 150 characters, you will have to pay for clicks every time a user clicks on ‘see more.’

Strong first page

This is the first thing people notice, so make sure it is visually appealing. You should also include the benefit here so the audience knows what they will get from the document.

Valuable first 3–5 pages

Whether the document is gated or ungated, users should learn something useful in the first few pages. Most people have a short attention span, and if you waste the first few pages on tables of contents, explaining methodology, or introducing your company, they will zone out.

The first few pages should contain your most valuable insights from the document, especially with gated content. If users don’t find anything useful in the preview pages, they will never fill out the Lead Gen Forms.

Mobile-first design

Most people use LinkedIn on their phones, so you should design ads that fit both desktops and phones. Designs that only work on desktops may not work well on mobile, giving users a bad experience.

You should:

• Use large fonts and short paragraphs
• Avoid using multiple columns
• Break information into bullets
• Use white space generously
• Use charts and images that adjust to small screens

Gated or ungated CTA

CTAs and URLs only become clickable once the document is read and downloaded. So if you must add them, use soft, low-friction CTAs for ungated content, such as Learn more or Visit our website.

For gated content, you can use stronger CTAs like Book a demo or Unlock document because of the Lead Gen Form.

LinkedIn Document Ads Examples and Use Cases

Here are some examples of document ads for reference:

Case study

Show prospects how you solved a customer’s problem to build trust with a warm audience.

• Best for: MOFU–BOFU
• Measure: document completion rate, demo requests, viral downloads

Templates

Give prospects something they can use immediately while introducing them to your brand.

• Best for: TOFU–MOFU
• Measure: downloads, Lead Gen Form completion (if gated)

Playbook

Teach buyers how to solve a problem and position your company as the expert.

• Best for: MOFU
• Measure: completion rate, engaged accounts, dwell time

Industry trend reports

Share original research or market trends to educate buyers and introduce them to your brand.

• Best for: TOFU
• Measure: downloads, account engagement, displays

Checklists

Help buyers identify gaps or assess whether they have a problem worth solving.

• Best for: TOFU
• Measure: downloads, completion rate

LinkedIn Document Ads vs Single Image Ads

Most marketers prefer single image ads over document ads because they are familiar and easy to produce. The results are also easier to measure. But neither format is better than the other. They serve different purposes and should not be judged using the same metrics.

When you want to promote content like case studies, guides, and ABM playbooks, use document ads to deliver the documents directly within the LinkedIn feed, instead of using single image ads that send readers back to the website for the same content.

But this does not mean you should abandon single image ads completely. You should use both formats simultaneously. Use single image ads to spark interest, then use document ads to nurture and educate the audience.

Here is a summary of how the two ad formats compare:

How to Measure LinkedIn Document Ads Performance

The biggest mistake we see advertisers make is measuring the success of document ads using surface-level metrics only.

If high CTR and clicks are your definition of success, then you’ll likely conclude that your document ad campaigns don’t work. In this section, we will look at the metrics advertisers should focus on and what they tell you about the campaign.

Basic campaign metrics

They help advertisers monitor campaign health. They include:

• Impressions – show how many times the audience saw the ad. If impressions are low, expand the audience size.
• Click-through rate (CTR) – indicates how well the creative (intro text, preview page, headline) influences people to open the document. If the CTR is low, test new creatives.
• Reach – shows how many unique individuals saw your content.

Content engagement metrics

These help you understand how the audience interacted with the content.

• Document opens – the number of times users open the document in their feed. High document opens mean the intro and cover page are excellent.
• Document completion rate – the percentage of users who read your document to the end.
• Viral completions – show how many users outside your target audience completed reading your content. You can identify the ones that match your ICP and retarget them in campaigns.
• Downloads – the number of times users downloaded the document. If people downloaded it, they found the content useful.
• Displays – how much of the document is displayed to users (25%, 50%, 75%). This helps advertisers find weak sections in the document.

Lead quality metrics

If you gated the document with a Lead Gen Form, use these metrics to measure conversion:

• Leads – the number of new leads you got from the campaign. If the volume is low, you can ungate the content to reach more people.
• Lead form opens and completion rate – the number of unique members who opened the form, and the number who completed it. If the open rate is high but the completion rate is low, the form might be too long or unclear in its messaging.
• Cost per lead (CPL) – the amount you spend to acquire a single lead. This is important when projecting costs for future campaigns.

Account-level and pipeline metrics

With account-level and pipeline metrics, you can see how document ads influence pipeline and prove LinkedIn ROI.

If you are running ABM campaigns, having account-level engagement data makes it easy to trace accounts interacting with your content.

Most attribution platforms can only identify companies, but DemandSense can identify both the companies and the individuals interacting with your ads. You need contact-level data to know whether you are reaching the right people at target accounts, and to find emails you can use to follow up on leads.

Once you have the company name, industry, job title, and seniority of your readers, these are the metrics you should focus on:

• Buying group coverage – the number of stakeholders who read or downloaded the document.
• Post-click website conversions – the number of people who visited your website after reading the document.
• Pipeline created – whether engaged accounts entered pipeline. If you have a lot of new opportunities from the document ads, the content shared was valuable to the audience.

Common Mistakes When Analyzing Document Ads

Evaluating only CTR

A high CTR tells you people opened the document, but not whether they read or loved the content. Likewise, a lower CTR does not necessarily mean the campaign failed. Evaluating campaign success on CTR alone can be misleading. Instead, pair CTR with engagement metrics like downloads, displays, or document completion rate to get a clear picture of how campaigns are performing.

Optimizing for cheap leads

This can be tempting, but when those cheap leads never convert to clients, you will have wasted the spend all the same.

Document ads are usually used to educate buyers who are not ready to convert immediately. So when you optimize for lead volume, you have to go broad with targeting and generalize content to accommodate everybody else. As a result, your content will attract the wrong audience.

Ignoring ungated engagement

Even though users don’t fill out Lead Gen Forms, it does not mean they are not interested in your content. Do not ignore the downloads, document completions, and website visits you get from ungated content. These are still strong buying signals.

Looking at LinkedIn ads separately from the CRM

When your LinkedIn ad metrics and CRM exist separately, it’s hard to tell if campaigns are influencing pipeline and revenue. But when you connect the two, you will be able to trace accounts, see the ones that were influenced by LinkedIn campaigns, and see the campaigns that are working.

Measuring individual leads but not company-level engagement

B2B buying decisions involve multiple stakeholders, and when running ABM campaigns, you should ensure the campaigns reach most members of the buying committee. Without account-level engagement data, you will never know how the buying committee engages with your ads.

Turn LinkedIn Document Ad Engagement Into Pipeline Insights with DemandSense

LinkedIn Campaign Manager can only tell you the clicks, impressions, and total downloads on your document, but it can’t identify the companies that interacted with your ads by name, the actions they took after reading the document, or whether they progressed into pipeline.

With attribution tools like DemandSense, you can connect your LinkedIn document ad data to your CRM and see how campaigns influence pipeline and revenue. DemandSense can identify both the companies and the individuals who interacted with your ads, even when they don’t fill out forms. You can also see the content that generates more sales-qualified leads and the content that is underperforming.

Frequently Asked Questions About LinkedIn Document Ads

---

What file types can you use for LinkedIn Document Ads?

You can use PDF, DOC, DOCX, PPT, and PPTX. But PDFs are the recommended format, because users download documents as PDFs regardless of the original format, and converting documents to PDFs affects the quality of the original doc.

---

Are LinkedIn Document Ads good for B2B lead generation?

Yes, they are good for lead generation. You can gate high-value content like case studies with Lead Gen Forms and get quality leads when prospects complete the form. Whether you gate the content or not, document ads make it easy for B2B businesses to educate and build trust with their audience. Most of these prospects turn into leads in the long run.

---

Should LinkedIn Document Ads be gated or ungated?

It depends on what you want to achieve with the campaign and the funnel stage of the target audience. If your goal is to generate leads, use gated document ads. And when you are targeting cold audiences (TOFU) and need more reach, it’s better to promote the content ungated.

---

What are the best LinkedIn Document Ad examples?

They include industry benchmarks, research reports, case studies, buyer’s guides, ROI calculators, checklists, whitepapers, and blogs.

---

What is the Document ad ungated experience?

When documents are ungated, LinkedIn users can preview, read, and download the document from their feed without completing Lead Gen Forms or leaving the platform. This low-friction experience is what sets LinkedIn document ads apart from other ad formats.
