Autumn 2025 YouTube Trends: Growth & Optimisation

As we move into autumn 2025, YouTube continues to be a powerhouse platform for brands and creators driving engagement, conversions and subscriber growth. This season brings new opportunities through influencer product reviews, the rapid rise of YouTube Shorts, and evolving SEO strategies to optimise video content for discovery. This guide explores the most important trends, with insights and ideas on how brands can make the most of them.

How Influencer Product Reviews Drive YouTube Conversions in 2025

Influencer product reviews remain one of the most effective ways to convert viewers into customers. Here’s how brands can maximise their impact:

• Authentic storytelling: Reviews that focus on real experiences, pain points and honest pros and cons perform far better than scripted endorsements.
• Top creator partnerships: Micro and mid-tier creators often achieve higher engagement and trust compared to mega influencers, thanks to niche expertise and relatability.
• Briefing for success: Provide clear product details and call-to-action suggestions, but leave influencers room to speak naturally.
• Multi-format reviews: Pair long-form deep dives with Shorts clips to deliver both detailed insights and quick hits of social proof.

How brands can use it: Work with influencers to deliver relatable, honest reviews that combine different formats, boosting both watch time and conversions.

YouTube Shorts Trends for Autumn 2025

Short-form vertical video continues to dominate, with Shorts now fully integrated into YouTube’s monetisation model.

• Updated monetisation: Creators share ad revenue directly, with eligibility requiring 1,000 subscribers plus either 10 million Shorts views in 90 days or 4,000 watch hours.
• Revenue streams: Earnings can also come from Super Thanks, channel memberships and product tagging via YouTube’s affiliate programme.
• Content trends: Tutorials, behind-the-scenes snippets, challenges, reactions and serialised mini-series are driving growth.
• Strategy tips: Post consistently, use trending music, hook viewers within the first 3 seconds, and include calls to action like shares and comments.

How brands can use it: Build momentum by experimenting with Shorts formats that showcase products in quick, creative ways. Consistency and early adoption of trends will keep content discoverable and engaging.

How to Optimise YouTube Videos for Search and Subscriber Growth

Search optimisation is still central to YouTube success. These tactics help ensure content is found and watched:

• Keyword research: Use auto-suggest and competitor analysis to identify the best terms for titles, descriptions and tags.
• Clickable thumbnails and titles: Incorporate keywords naturally without clickbait.
• Consistent publishing: Post regularly to signal activity to the algorithm and build routine viewership.
• Engagement tactics: Encourage comments, likes and subscriptions with CTAs, pinned comments and end screens.
• Playlists and chapters: Improve user experience and watch time by grouping related content.
• Analytics monitoring: Track retention, demographics and traffic sources to refine strategy.

How brands can use it: Prioritise keyword-driven titles and descriptions, maintain a steady publishing schedule, and design videos to maximise engagement and discoverability.
