LinkedIn Document Ads: A Complete Guide to B2B Lead Generation

LinkedIn Document Ads offer a powerful way to share in-depth content and generate high-quality leads directly within the LinkedIn feed. Unlike traditional ads that send users to an external landing page, this format allows professionals to view, read, and download valuable assets like ebooks, whitepapers, and reports without ever leaving the platform. This seamless, native experience reduces friction, which can significantly increase engagement and lead capture efficiency. By gating content with an integrated Lead Gen Form, businesses can capture valuable contact information from users who are genuinely interested in their offerings, positioning the brand as a thought leader and effectively nurturing prospects through the marketing funnel.

What are LinkedIn Document Ads and how do they work?

LinkedIn Document Ads are a type of sponsored content that allows you to promote documents such as PDFs, PowerPoint presentations, or Word files directly in the LinkedIn feed. Instead of clicking a link to an external website, users can scroll through and read the document within an interactive viewer on LinkedIn. This creates a seamless user experience, which is known to reduce drop-off rates. Advertisers can choose to share the document freely to build brand awareness or "gate" it with a native LinkedIn Lead Gen Form to capture high-quality leads. When a document is gated, users can see a preview, but must fill out the pre-populated form to unlock and download the full version.

Are Document Ads more effective for generating leads than sending users to a landing page?

Yes, for lead generation, Document Ads with an integrated Lead Gen Form are often more effective than ads that direct users to an external landing page. The primary advantage is the frictionless user experience; because the user never leaves the LinkedIn platform, the process is faster and simpler, which significantly reduces drop-off. LinkedIn Lead Gen Forms can auto-populate with a user's profile information, further simplifying the submission process. Data suggests that the average conversion rate for LinkedIn Lead Gen Forms is around 13%, which is substantially higher than the typical 2-4% conversion rate for traditional landing pages. This makes them a highly efficient and cost-effective tool for capturing high-quality leads.

What type of content works best as a Document Ad (e.g., ebooks, whitepapers, case studies)?

Content that provides in-depth, educational, and actionable insights performs best for Document Ads. The format is ideal for assets that would typically be gated, as it allows you to showcase significant value. High-performing content types include: ebooks, whitepapers, and industry reports. Case studies and success stories are also effective for demonstrating results. Additionally, infographics, data sheets, analyst reports, and presentation slides from webinars can be repurposed into compelling Document Ads. The key is to offer content that positions your brand as a thought leader and addresses your audience's specific pain points.

Can we gate the document so users have to fill out a lead gen form to see the full version?

Yes, gating documents with a Lead Gen Form is a core feature and a primary strategy for using this ad format for lead generation. When you set up a gated Document Ad, users in the feed can view a limited preview of the first few pages. To access the full document, they must click a call-to-action like "Unlock Document" and complete the integrated Lead Gen Form. Once the form is submitted, the user receives the full document, and their contact information is captured for your CRM. This method is highly effective for converting engaged viewers into actionable leads.

How do you design a PDF to be easily readable within the LinkedIn document viewer?

To ensure readability, especially on mobile devices, it's best to design your PDF like a presentation rather than a text-heavy document. Use large fonts (at least 8pt), bold colors, and high-quality visuals to make the content scannable and engaging. Break up text with images, bullet points, and graphics. A square format is often recommended as it performs well across various placements. Keep the document concise, ideally under 10 pages, to maintain user engagement. It's also helpful to include visual cues, like arrows, to prompt users to scroll to the next page.

Are Document Ads more expensive than standard single-image or carousel ads?

The cost of LinkedIn Document Ads can vary widely based on your objective, targeting, and bidding strategy. While the Cost Per Click (CPC) can sometimes be higher than for standard image ads, Document Ads often prove more cost-effective for awareness and lead generation due to their significantly higher engagement rates. Some reports show Document Ad engagement rates can be as high as 8-12%. When paired with a Lead Gen Form, the cost per lead can be lower than driving traffic to a landing page because of the higher conversion rates. A/B testing different objectives, such as 'Engagement' versus 'Website Visits', is recommended to find the most efficient cost structure for your specific goals.

How do we track engagement with a Document Ad beyond just clicks?

LinkedIn provides detailed analytics for Document Ads that go far beyond simple clicks. You can measure how much of your document is being viewed by tracking view percentages at 25%, 50%, and 75% completion rates. Other key metrics include total downloads, document clicks (clicks on the download button), and viral download clicks (downloads from a shared post). When using a Lead Gen Form, you can also track the form open rate and completion rate. These granular metrics offer deep insights into how engaging your content is and help you identify areas for optimization.

Should we A/B test a Document Ad against a standard ad leading to the same asset on a landing page?

Yes, A/B testing a Document Ad with a native Lead Gen Form against a traditional ad that directs to a landing page is a highly recommended strategy. This allows you to directly compare the effectiveness and cost-per-lead of each approach. While LinkedIn doesn't have a built-in A/B testing tool like other platforms, you can set up two separate campaigns with the same audience and budget to compare performance. This test will help you determine whether the seamless, in-platform experience of a Document Ad generates more qualified leads at a lower cost than the traditional landing page funnel for your specific asset and audience.

What are the creative best practices for the cover page of a Document Ad?

The cover page is the most critical element for capturing attention in the feed. It should be visually appealing, with a professional design, high-quality images, and strong color contrast to stand out against LinkedIn's user interface. The headline should be concise (under 70 characters) and compelling, clearly communicating the document's value. It's also recommended to include your company logo to build brand recognition. The goal is to create a powerful first impression that entices users to stop scrolling and engage with your content.

Can we use Document Ads for middle-of-funnel content or are they strictly for bottom-of-funnel?

Document Ads are highly versatile and can be used effectively across different stages of the marketing funnel. For top-of-funnel and middle-of-funnel (MOFU) strategies, you can share ungated educational content like ebooks, whitepapers, and industry reports to build brand awareness and thought leadership. For middle- and bottom-of-funnel (BOFU) objectives, gating the same high-value content with a Lead Gen Form is an excellent way to capture qualified leads. You can also use Document Ads in retargeting campaigns to nurture audiences who have previously engaged with your brand, moving them closer to conversion.
