You create an event, design a great poster, write compelling copy, and post it on your social media channels. Then you watch as the post reaches a fraction of your followers and generates a handful of interactions. The algorithm has decided that your content is not interesting enough to show to most of your own audience, let alone to new potential attendees.
This is the reality for event organisers marketing on social media in 2026. Understanding how algorithms make these decisions is not optional -- it is essential for anyone relying on social platforms to sell tickets.
How algorithms decide what to show
Every major social platform uses a recommendation algorithm that decides which content appears in each user's feed. The specifics differ between platforms, but the core principle is the same: the algorithm predicts which content each user is most likely to engage with (like, comment, share, watch, or click) and prioritises that content.
The algorithm considers several factors:
- Past interaction history -- If a user has engaged with your posts before, they are more likely to see your new posts. Conversely, if they have scrolled past your last several posts without interacting, the algorithm deprioritises your content for that user.
- Content type performance -- The algorithm tracks how each user interacts with different content types (videos, images, carousels, text posts, stories) and prioritises the types they engage with most.
- Early engagement signals -- When you publish a post, the platform shows it to a small subset of your audience first. If that initial group engages strongly, the algorithm shows it to more people. If they do not, the post's reach is limited.
- Recency -- Newer content generally ranks higher than older content, though the decay rate varies by platform.
- Content category -- Platforms categorise content by topic. If a user frequently engages with music content, they are more likely to see event posts tagged or identified as music-related.
Platform-specific behaviour
Instagram's algorithm heavily favours Reels (short-form video) over static images and carousels in 2026. The platform's recommendation system shows Reels from accounts users do not follow, which makes them the best format for reaching new audiences. For event organisers, this means that short, engaging video content (venue walkthroughs, artist previews, behind-the-scenes clips, audience reactions from past events) will reach more people than a static event poster.
Instagram Stories have a separate algorithm that prioritises accounts the user interacts with most frequently. Stories are good for communicating with existing followers but poor for reaching new ones. The algorithm also considers how quickly a user responds to Stories (via replies or reactions) when ranking future Stories from that account.
TikTok
TikTok's recommendation system is the most aggressive at showing content from accounts users do not follow. The For You page is driven almost entirely by content performance rather than follower relationships. A video from an account with 50 followers can reach hundreds of thousands of people if it performs well in early testing.
For event organisers, TikTok offers the highest potential reach per post, but also the highest unpredictability. Content that is entertaining, surprising, or emotionally resonant performs best. Straightforward event announcements perform poorly. The TikTok effect on event discovery has been significant for events that create genuinely engaging content.
Facebook's algorithm in 2026 strongly prioritises content from Groups and content that generates meaningful interactions (comments and shares rather than just likes). For event organisers, Facebook Groups related to your event's niche (local music scenes, specific interest communities, regional what's-on groups) can be more effective than posting on your Page.
Facebook Events still exist and can be useful for discovery, particularly for local events. When someone marks themselves as "Interested" in your event, the algorithm may show the event to their friends, creating organic spread. However, Facebook's overall reach for business pages has declined steadily, and organic reach from Page posts is typically in the low single-digit percentages of your follower count.
X (formerly Twitter)
The algorithm on X prioritises content that generates replies and conversation. Simple announcement posts perform poorly. Posts that ask questions, share opinions, or provoke discussion reach more people. For event organisers, engaging in conversation about your event's topic (rather than just promoting the event) tends to build more visibility over time.
Strategies that work across platforms
Despite the differences between platforms, some principles apply broadly:
Create content that is worth engaging with on its own merits
The most common mistake is posting content that is only interesting if you already want to attend the event. "Tickets now on sale for [Event Name] on [Date]!" is not content that anyone wants to like, comment on, or share. It is an advertisement. Algorithms treat it accordingly.
Instead, create content that is valuable or entertaining regardless of whether the viewer buys a ticket. A behind-the-scenes video of the venue being set up is interesting even if you are not attending. An interview with a performer has standalone value. A funny or surprising clip from a past event is shareable on its own merits. These posts earn engagement, which earns algorithmic reach, which eventually drives ticket awareness and sales.
Post consistently, not just when you have something to sell
Algorithms reward accounts that post regularly and generate consistent engagement. If you only post when you have a ticket link to share, your account will have low baseline engagement, which means low reach when it matters most. Posting valuable content between events keeps your audience engaged and your algorithmic ranking healthy.
Use video, especially short-form
Every major platform is prioritising video content, particularly short-form vertical video. This is not a temporary trend; it reflects how users are consuming content. Event organisers who invest in creating short, engaging videos will consistently outperform those who rely on static images.
You do not need professional production. Smartphone footage that is genuine, well-lit, and has good audio outperforms overproduced content on most platforms. Authenticity resonates more than polish in the current social media environment.
Engage with your community
Reply to comments. Respond to messages. Engage with other accounts in your niche. Algorithms notice reciprocal engagement and factor it into content distribution. An account that posts and ghosts will underperform an account that actively participates in its community.
The paid advertising question
Given the limitations of organic reach, many organisers supplement with paid social advertising. Paid content bypasses the organic algorithm and is shown based on your targeting criteria and bid amount. For driving ticket sales, a combination of strong organic content (for awareness and credibility) and targeted paid campaigns (for direct conversion) typically delivers the best results.
The key is to use organic content to test what resonates with your audience, then put paid spend behind the content that performs best. This data-informed approach is more effective than boosting every post or running ads with untested creative.
Social media algorithms are not your enemy. They are a system you can work with if you understand the rules. Create genuinely engaging content, post consistently, use video, and engage with your community. The algorithms will reward you with reach, and that reach will translate to measurable ticket sales.
