LinkedIn Sponsored Content: Single Image, Video, Carousel and Document Ads

Table of Contents

What Is LinkedIn Sponsored Content

LinkedIn Sponsored Content refers to paid advertisements that appear directly in the LinkedIn news feed alongside organic posts. These ads look and feel like native content, which is why they consistently achieve the highest engagement rates among all LinkedIn ad formats.

Sponsored Content is the backbone of most B2B advertising strategies on LinkedIn. Unlike Text Ads that sit in the sidebar or Message Ads delivered to inboxes, Sponsored Content integrates seamlessly into the scrolling experience. Users encounter these ads as they browse updates from their connections and followed companies, making them less intrusive and more engaging.

For Singapore businesses running B2B campaigns, Sponsored Content supports all major campaign objectives including Brand Awareness, Website Visits, Engagement, Video Views, Lead Generation and Website Conversions. This flexibility makes it the most versatile ad placement on the platform. Combined with LinkedIn’s professional targeting capabilities outlined in our LinkedIn ads guide, Sponsored Content delivers precise reach to decision-makers across industries.

LinkedIn offers four Sponsored Content formats: Single Image, Video, Carousel and Document Ads. Each format serves different content types and campaign goals. Choosing the right format for your message is essential to maximising engagement and minimising LinkedIn ads cost.

Single Image Ads

Single Image Ads are the most widely used Sponsored Content format. They feature one image accompanied by introductory text, a headline, a description and a call-to-action button. Their simplicity makes them easy to produce and test at scale.

Specifications:

  • Image size: 1200 x 627 pixels (landscape) or 1080 x 1080 pixels (square)
  • File type: JPG or PNG
  • Maximum file size: 5 MB
  • Introductory text: Up to 600 characters (150 characters visible before truncation)
  • Headline: Up to 200 characters (70 characters recommended)
  • Description: Up to 300 characters (displayed below the headline on some placements)

When to use Single Image Ads:

  • Promoting blog posts, articles and thought leadership content
  • Driving webinar and event registrations
  • Gating whitepapers, reports and guides behind Lead Gen Forms
  • Product and service announcements
  • Customer success stories and testimonials

Performance tips for Singapore: Square images (1080 x 1080) take up more feed real estate on mobile devices, which account for over 60 percent of LinkedIn usage in Singapore. Use bold, contrasting colours that stand out in the feed. Include text on the image sparingly to communicate your key message at a glance, but keep text to under 20 percent of the image area.

Avoid generic stock photography. Custom graphics, data visualisations, branded templates and authentic business photography perform significantly better. Your brand identity should be recognisable across all ad creative.

Video Ads

LinkedIn Video Ads play natively in the feed and auto-play on mute as users scroll. Video content generates 5 times more engagement than static posts on LinkedIn, making it a powerful format for capturing attention in a crowded feed.

Specifications:

  • Aspect ratios: 16:9 (landscape), 1:1 (square) or 9:16 (vertical)
  • Duration: 3 seconds to 30 minutes (15 to 90 seconds recommended)
  • File type: MP4
  • Maximum file size: 200 MB
  • Resolution: 360p minimum, 1080p recommended

When to use Video Ads:

  • Explaining complex products or services visually
  • Sharing customer testimonials and case studies
  • Building brand awareness with storytelling
  • Demonstrating software, platforms or tools
  • Repurposing webinar highlights and event content

Video creative guidelines: Always include captions since the majority of LinkedIn users watch videos without sound. Lead with your most compelling message in the first 3 seconds. Keep videos under 30 seconds for awareness campaigns and under 90 seconds for consideration content. Square and vertical formats perform better on mobile.

For B2B companies in Singapore, talking-head videos from subject matter experts tend to outperform highly produced corporate videos. Authenticity and expertise matter more than production quality on LinkedIn. Consider creating a video content series that builds thought leadership over time as part of your broader content marketing strategy.

Carousel Ads display a series of 2 to 10 swipeable cards, each with its own image, headline and destination URL. This format encourages interaction through swiping and allows you to tell a more complete story than a single image can convey.

Specifications:

  • Number of cards: 2 to 10
  • Image size: 1080 x 1080 pixels per card
  • File type: JPG or PNG
  • Maximum file size: 10 MB per card
  • Headline per card: Up to 45 characters
  • Introductory text: Up to 255 characters

When to use Carousel Ads:

  • Showcasing multiple products or services
  • Presenting sequential processes or methodologies
  • Sharing data points and statistics
  • Telling a brand story across multiple slides
  • Highlighting different features or benefits

Carousel strategy tips: Design each card to be compelling independently while also telling a cohesive story when viewed in sequence. Use the first card as a strong hook since it determines whether users swipe. Number your cards (for example, 1 of 5) to signal there is more content to discover.

Create a visual narrative that builds to a conclusion on the final card, which should contain your strongest CTA. Singapore B2B companies have found success using carousels to present industry benchmarking data, step-by-step implementation guides and before-and-after transformation stories.

Document Ads

Document Ads allow you to share PDFs, PowerPoints and Word documents directly in the LinkedIn feed. Users can scroll through the document without leaving LinkedIn, creating an immersive content experience. This format is particularly effective for B2B content in Singapore.

Specifications:

  • File types: PDF, DOC, DOCX, PPT, PPTX
  • Maximum file size: 100 MB
  • Maximum pages: 300 (10 to 20 pages recommended)
  • Recommended page size: Standard letter or A4

When to use Document Ads:

  • Industry reports and research findings
  • Detailed how-to guides and playbooks
  • Presentation decks and slide shares
  • Infographics and data visualisations
  • Product catalogues and comparison guides

Document Ads best practices: Design your document for mobile viewing with large text, bold graphics and minimal paragraphs. The first 2 to 3 pages must capture attention since most users decide quickly whether to continue reading. For lead generation, you can gate the document so users see a preview of the first few pages and must submit a Lead Gen Form to access the full content.

Document Ads consistently achieve higher engagement rates than Single Image Ads because the interactive scrolling format encourages users to spend more time with your content. This deeper engagement improves your ad relevance score and can reduce costs over time. Singapore B2B companies offering consulting, technology and financial services have found Document Ads particularly effective for establishing thought leadership and generating qualified leads.

Creative Best Practices for Singapore

Creating Sponsored Content that resonates with Singapore’s professional audience requires understanding the local B2B landscape. Here are guidelines that improve performance across all formats.

Write compelling introductory text: The first 150 characters of your introductory text determine whether users expand your post. Lead with a provocative question, surprising statistic or clear value proposition. Avoid corporate jargon and speak directly to your audience’s challenges.

Tailor content to seniority: C-suite executives respond to strategic content about industry trends and business outcomes. Mid-level managers engage with tactical content about processes, tools and implementation. Junior professionals interact with educational and career development content. Match your creative to your targeting.

Leverage Singapore-specific insights: Reference local business conditions, regulatory environments, market trends or cultural nuances. Content that mentions Singapore-specific challenges (talent shortages, rising costs, regional expansion) resonates more than generic global content.

Social proof matters: Singapore professionals trust peer validation. Include client logos, testimonial quotes, specific results (e.g., “helped 50 Singapore companies reduce costs by 30 percent”) and third-party recognition in your creative.

Strong CTAs: Be specific about what users will receive. “Download the 2026 Singapore Marketing Report” outperforms “Learn More.” Align your CTA with the value exchange and ensure your landing page delivers exactly what the ad promises.

Mobile-first design: Over 60 percent of LinkedIn usage in Singapore happens on mobile devices. Test all creative on mobile screens before launching. Ensure text is readable, images are clear and CTAs are prominent on smaller screens.

Performance Optimisation and Testing

Continuous testing and optimisation separates high-performing Sponsored Content campaigns from underperforming ones. Apply these practices systematically.

A/B testing framework: Run 3 to 5 ad variations within each campaign. Test one variable at a time: introductory text, image or video, headline, CTA or ad format. LinkedIn automatically allocates more budget to better-performing ads, but you should review data manually every 3 to 5 days.

Performance benchmarks to target:

  • CTR for Single Image Ads: 0.40 percent or higher
  • CTR for Video Ads: 0.35 percent or higher
  • CTR for Carousel Ads: 0.40 percent or higher
  • Video view rate (25 percent completion): 20 percent or higher
  • Document engagement rate: 1.5 percent or higher

Creative refresh cycle: Refresh creative every 4 to 6 weeks or when you notice performance decline. LinkedIn’s professional audience is smaller than consumer platforms, which means ad fatigue occurs faster. Maintain a content calendar that ensures fresh creative is always ready.

Audience insights analysis: Use LinkedIn’s Demographics reporting to understand which professional segments engage most with your Sponsored Content. Identify patterns in job function, seniority, industry and company size. Use these insights to refine both your targeting and creative messaging.

Cross-format testing: Do not assume one format works best for all messages. Test the same core message as a Single Image, Video and Document Ad to determine which format resonates most with your target audience. Many Singapore B2B companies discover that Document Ads outperform expectations for lead generation.

Integrate your LinkedIn Sponsored Content performance data with your overall digital marketing analytics to understand how LinkedIn contributes to your full marketing funnel. Track not just platform metrics but downstream outcomes like lead quality, pipeline value and closed revenue attributed to LinkedIn.

Frequently Asked Questions

What is LinkedIn Sponsored Content?

LinkedIn Sponsored Content is paid advertising that appears in users’ LinkedIn news feeds alongside organic posts. It includes Single Image, Video, Carousel and Document ad formats. Sponsored Content is the most engaging and widely used LinkedIn ad placement for B2B marketing.

Which Sponsored Content format performs best?

Performance depends on your content and objective. Single Image Ads are the most versatile and easiest to produce. Video Ads generate the highest engagement. Document Ads often deliver the best cost-per-lead. Carousel Ads work well for storytelling. Test multiple formats to find what works for your audience.

What image size should I use for LinkedIn Sponsored Content?

For Single Image Ads, use 1200 x 627 pixels for landscape or 1080 x 1080 pixels for square format. Square images are recommended for mobile-heavy audiences since they occupy more screen real estate. For Carousel Ads, each card should be 1080 x 1080 pixels.

How long should LinkedIn video ads be?

LinkedIn recommends 15 to 30 seconds for awareness campaigns and up to 90 seconds for consideration content. Videos can be up to 30 minutes long, but completion rates drop significantly after 90 seconds. Always place your key message in the first 3 seconds and include captions.

Can I gate Document Ads behind a lead form?

Yes. Document Ads can be configured to show a preview of the first few pages and then require users to submit a LinkedIn Lead Gen Form to access the full document. This creates an effective content-gated lead generation mechanism directly within the LinkedIn feed.

How much does LinkedIn Sponsored Content cost?

In Singapore, Sponsored Content typically costs SGD 4 to SGD 18 per click and SGD 30 to SGD 90 per 1,000 impressions. Costs vary by targeting specificity, industry competition and ad relevance. Higher engagement rates lead to lower costs through improved auction performance.

Should I boost organic posts or create new Sponsored Content?

Both approaches have merit. Boosting successful organic posts leverages proven engagement signals, similar to how TikTok Spark Ads work. Creating dedicated Sponsored Content gives you full control over messaging and can include Lead Gen Forms. Most effective campaigns use a combination of both.

How many ad variations should I test?

Run 3 to 5 ad variations per campaign to gather meaningful performance data. Test one variable at a time for clear insights. LinkedIn’s algorithm distributes budget toward better-performing ads automatically, but manual review every few days ensures you catch underperformers early.
