Social Media Trends for 2027: What to Act On, Test and Ignore
Every autumn brings a new batch of social media trend reports, and most of them agree with each other: video, AI, authenticity, community. The current social media trends they describe are mostly accurate. What they rarely do is take the next step: telling you which ones deserve budget, which ones deserve a small test, and which ones you can leave to someone else.
This guide does that sorting. It draws on the 2026 research from Sprout Social and Hootsuite, UK audience data, and the way we plan social for brands, including those in regulated sectors such as health and pet care.

1. Social platforms have become search engines
Act now
Sprout Social's Q2 2025 Pulse Survey found that nearly one in three consumers now begin their searches on TikTok, Instagram or YouTube rather than Google, and that the figure passes half among Gen Z. In the UK, 49% of Gen Z use TikTok for product discovery, while Facebook remains the leading network for it overall, with close to 40% of social users finding new products there and 24% turning to YouTube. Google has also started indexing public Instagram content and short-form video from other platforms.
A post now has two jobs. It has to hold attention in the feed on the day it goes out, and it has to answer a question typed into a search bar weeks later. Feed content fades within days. Search-led content keeps collecting views for as long as it matches the words people actually use.
Start from keyword research, not from the content calendar. The questions your customers type into Google are usually the ones they type into TikTok, so your SEO keyword data is already a brief for social. Captions, on-screen text and video transcripts are what platforms and AI tools read to decide which content answers a query, so put the key phrase in all three, spoken as well as written. Favour answer-led formats: how-tos, comparisons, "what to check before you buy".
Track the share of views coming from search where the platform reports it (TikTok breaks traffic sources down per video), and watch which videos are still gaining views after their first week.
2. Series are replacing one-off posts
Act now
When Sprout Social asked consumers what they most want from brands on social, interacting with audiences (58%) and original content series (57%) came out almost level. Hootsuite's 2026 research points to the rise of short social-first series, with Deloitte forecasting $7.8 billion in revenue for the format this year.
A series gives people a reason to come back, and a returning viewer sends a stronger signal to the algorithm than a new one who scrolls past. It also solves a production problem most teams have: a fixed format is faster to brief, film and approve than a new idea every week.
Choose one format built on something you know better than your competitors. For example: one customer question answered in under a minute, a monthly teardown of a campaign, or a specialist explaining one topic per episode. Keep the same face, the same slot and the same structure. Commit to six to eight episodes before judging it, because early episodes rarely perform. If the series needs a proper content strategy or video production behind it, plan that before episode one.
Follows per episode, completion rate and the proportion of returning viewers.
3. Community is moving into smaller, private spaces
Act now (consumer), test (B2B)
Sprout Social's UK data shows 85% of users interact with brands on WhatsApp at least once a week, the highest rate of any region surveyed, and 40% want companies to be there specifically for customer service. Ofcom's Online Nations Report 2025 places WhatsApp ahead of every other platform for reach across all UK age groups. Around three quarters of social users expect a reply from a brand within 24 hours, and most say they will buy from a competitor if they get no answer at all.
As public reach gets harder to earn, the relationship moves into DMs, broadcast channels and groups. Community management can no longer be something done between posts. It needs an owner, a response-time standard and clear escalation rules.
Set a response-time target and staff it before you invite more conversations. Open a private channel only if you have something worth putting in it: early access, expert updates, faster support. For B2B, the equivalent is usually a LinkedIn newsletter or a closed group for clients, and it belongs in the test column rather than the plan.
Median response time, the share of conversations resolved in the channel, and saves and shares, which are the signals private audiences leave behind.
4. AI behind the scenes, people on screen
Act now
Nearly a third of consumers say they are less likely to choose a brand that uses AI-generated ads. Just over half of social users (52%) are concerned about brands posting AI-generated content without disclosing it, and 46% are not comfortable with brands using AI influencers. Meanwhile, UK marketers have made AI-generated content their top priority for 2026, even though consumers put human-made content first, and only 40% of marketers use AI for performance reporting and analysis.
That gap is the opportunity. The split we recommend is simple. Use AI where the audience never sees it: social listening, reporting, sorting comments, resizing one video into several formats, drafting briefs. Keep faces, voices and opinions human. When AI-generated visuals do appear in something you publish, label them.
Compare engagement and comment sentiment on human-led content against AI-assisted content over a quarter, rather than relying on instinct.
5. Creators and employees are becoming the main voices
Test
Hootsuite reports that brands are moving from one-off creator posts to ongoing partnerships judged on return, and cites Edelman's finding that audiences trust employees more than influencers or CEOs. Bazaarvoice found that 30% of UK shoppers have bought a product on a creator's recommendation.
Follower counts are losing their place as the way to pick creators. What matters is audience fit and what the partnership delivers in sales, leads or cost per acquisition. Creator content also has a second life: it can run as paid social ads, which lets you judge it against your own brand creative on the same cost-per-result basis.
For B2B, the same logic applies to your own people, mostly on LinkedIn. A specialist explaining their work reaches further and earns more trust than the company page repeating it. Employee advocacy needs a light framework: agreed topics, a review route for anything regulated, and no forced reposts.
Under UK rules, any content a creator is paid or rewarded for must be clearly labelled as advertising, usually with "#ad" at the start. That applies to gifted product too.
Cost per result of creator-led ads against brand ads, and reach and profile visits from employee posts.
6. Build your channel mix from audience data, not from the hype
Act now
UK marketers plan to put most of their 2026 effort into TikTok (73%), Instagram (69%) and Facebook (64%). Asked where they will actually spend more time, UK consumers put Facebook first (34%), followed by TikTok and WhatsApp (29% each) and YouTube (25%).
TikTok is the right call for many brands, just not by default. The audience also looks different from the stereotype. Hootsuite notes that Gen X holds the most spending power of any generation, and cites CivicScience data showing TikTok users aged 45 and over grew by 1,200% between 2019 and 2025.
Worth watching, not yet worth a plan: 4.3 million UK adults visited Threads according to Ofcom, and Hootsuite flags LinkedIn's push into video and Substack's shift into a full social platform as the two to experiment with.
Put two numbers side by side for each platform: where your audience's time sits, and where your team's time and budget go. Cut or reduce the platform with the weakest evidence before adding a new one.
7. Social content now feeds Google and AI answers
Test
Posts from Reddit, YouTube and Instagram increasingly appear in Google results, and what you publish on social is becoming part of the material search engines and AI assistants draw on when they describe your brand or answer a question in your category.
Social, SEO and generative engine optimisation (GEO) now work from the same raw material. An expert explanation filmed for LinkedIn can support a blog article, answer a query in Google, and shape how an AI assistant summarises your expertise.
Align topics across channels, so the questions you answer on social match your search priorities. Keep brand facts consistent everywhere: name, description, specialism and location. AI tools build their summary of a brand from many sources, and contradictions weaken it.
Branded search volume over time, and how AI assistants describe your brand when asked about your category, checked every quarter.
Instagram trends worth knowing
Instagram deserves its own note, because it sits at the centre of several of the trends above. It is the platform UK consumers use most to keep up with trends, cited by 54% in Sprout Social's UK Index. Reels can now run to 20 minutes, which opens the door to longer explainers and series episodes. Broadcast channels offer a private layer for your most engaged followers. And since public posts can now surface in Google, captions deserve the same care as any web copy.
What we would deprioritise
- Jumping on trending audio for its own sake. Trend cycles on social have become so short that many trends are over within moments. Unless you can approve and publish within a day or two, you will arrive after the audience has moved on.
- Opening an account on every new platform. Without evidence your audience is there, a new profile takes resource away from the ones that work.
- AI-generated influencers. Consumer discomfort is high, and the trust cost outweighs the production saving.
- Volume as a goal. Brands published an average of 9.5 posts a day across networks in 2024. More posts rarely fix weak ones.
A note for regulated and specialist sectors
Health, pet care, veterinary and financial brands can use every trend in this guide, but with tighter guardrails. In the UK, prescription-only medicines, human or veterinary, cannot be advertised to the public, and that restriction extends to creators and employees posting on your behalf. Health claims need substantiation, whoever makes them.
The formats that suit these sectors best are the ones built on expertise: series fronted by qualified professionals, answer-led content for social search, and private channels for professional audiences. The practical rule is to agree the approval route before launching a series, not after the first episode is filmed. We cover this in more detail in our vet marketing work.
Turning trends into a plan: six questions
- Do we answer our customers' three most common questions in video, using the words they search with?
- Do we have one recurring format with a recognisable face?
- What is our response time in comments and DMs, and who owns it?
- Where does AI sit in our workflow, and is any of it visible to the audience?
- Is our budget split by platform backed by audience data from the last twelve months?
- Do our social topics match our SEO and GEO priorities?
If more than two of these have no clear answer, that is where to start. It is also where our work as a social media agency usually begins: with the audit, before any new content.
FAQ
What are the most important social media trends for 2027?
Social platforms used as search engines, series replacing one-off posts, community moving into private channels, human-led content with AI kept behind the scenes, creators and employees as the main brand voices, channel budgets led by audience data, and social content feeding Google and AI answers.
Is TikTok still worth it for B2B brands?
It depends on your audience evidence, not on the platform's reputation. TikTok's audience is older than many assume, but LinkedIn remains the core channel for most B2B brands. If you test TikTok, test it with a series, not scattered posts.
Should brands use AI-generated content on social media?
Use AI for listening, reporting, versioning and drafting. Be cautious with AI-generated faces, voices or ads, which a significant share of consumers distrust, and label AI-generated visuals when you use them.
How do you know if a social media trend is working for your brand?
Pick one metric per trend before you start: search-sourced views for social search, returning viewers for series, response time for community, cost per result for creator content. Judge it after a set period, not after the first post.
How many social media platforms should a brand be on?
As many as you can run well, and no more. Two platforms managed properly, with a response standard and a consistent format, outperform five run on leftover time.
