An 800x999 pixel image on LinkedIn takes up the entire mobile screen, eliminating competition from other posts. This increases scroll time on your content, giving it a higher chance of engagement by making it the sole focus for the user.

Ads originating from an individual's profile on LinkedIn, known as thought leader ads, leverage authenticity and personal branding. They achieve significantly higher engagement—a 2.2x higher click-through rate—compared to traditional single-image ads from a company page, demonstrating the power of human-centric content.

Metrics show content with "invisible interactions" (clicks, carousel swipes, video views) performs significantly better. These actions signal deep engagement to the algorithm, boosting reach even without traditional likes or comments, which are declining in importance.

As Instagram is flooded with Reels, the less-common carousel format offers a significant reach advantage. Repurpose existing talking-head Reels by creating a two-slide carousel: the first slide is a static image with a compelling headline, and the second slide is the original Reel. This is a low-effort, high-impact strategy.

To maximize engagement, size your LinkedIn images to 800x999 pixels. This specific ratio takes up the entire mobile screen, eliminating competing posts from view and increasing the user's scroll time on your content, which significantly boosts the chances of interaction.

While most creators focus on short-form video, data from late 2025 indicates that Instagram carousels generate significantly more reach and engagement among a creator's existing followers. This presents a strategic opportunity to re-focus on a less saturated, high-performing format.

Data from Social Insider reveals that for LinkedIn pages with 1-5,000 followers, multi-image posts generate the highest average like count (30), surpassing single images (27) and even video (23). This suggests a valuable, and often overlooked, format for smaller accounts to test for increased engagement.

Data shows a split in performance between post types. Instagram's algorithm favors Reels for reach, showing them to more people. However, audiences are more likely to engage with Carousels, which see higher engagement rates (6.9% median for Carousels vs. 3.3% for Reels). A balanced strategy should include both formats.

Data shows LinkedIn's document posts (carousels) massively outperform other content. They earn 278% more engagement than video and 596% more than text-only posts. The feature, found via a specific 'document' icon when creating a post, is a key opportunity for marketers to boost reach.
