How to Find Trending Topics on Social Platforms
You post something. It gets eleven likes and a comment from your mum. Two days later a competitor posts about the same subject and it takes off. That gap is rarely about better writing or nicer graphics. It is usually about timing, and timing comes down to knowing which trending topics on social media are worth your attention right now.
I have spent 18 years running marketing for businesses across Derbyshire and the wider East Midlands, and this is one of the questions I get asked most often. Owners know they should be "on trend" but nobody ever showed them where to actually look.
This guide walks through exactly where to find trending topics on social media, platform by platform, plus the listening tools and audience habits that separate businesses who post consistently from businesses who post well.

Algorithms reward content that people are already engaging with elsewhere. When a topic is trending, the platform is actively trying to surface more content about it, because that is what keeps people scrolling. Post about that same topic and you get a head start you cannot buy with a bigger budget.
It also puts your brand inside conversations people already care about, rather than asking them to care about a conversation you started cold. That is a much easier sell for a Derbyshire SMB with a modest marketing budget than trying to manufacture demand from nothing.
None of this replaces a proper social media strategy. Trend-spotting is one tactic inside a bigger plan, not the plan itself. But used well, it is one of the cheapest ways to get extra reach.
Use Each Platform's Own Trend Tools
Every major platform has a built-in section showing what is gaining traction. Most businesses never open them. That is the first easy win.
X (formerly Twitter): Explore and Trending Tags
The Explore tab splits into "For you," "Trending," and "News," giving you a live read on what is being talked about locally and globally. The trending list on the sidebar is worth checking daily if X is part of your mix.
Instagram: Explore Page and Hashtags
Instagram's Explore feed reflects both your interests and the wider trends moving through the platform. Search hashtags relevant to your industry and watch which ones are climbing. A hairdresser in Ashbourne and a joiner in Wirksworth will see completely different trending tags, which is exactly the point.
Facebook: Groups and News Feed
Facebook dropped its dedicated Trending section a while back, but active local and industry groups still surface what people care about in real time. If you serve a specific East Midlands community, the Facebook groups for that area are often a better trend source than the platform's own algorithm.
TikTok: The Discover Page
TikTok's Discover page is the most reliable trend signal of any platform right now. Recurring sounds and hashtags are an early warning system. If you spot the same audio turning up across your For You page three or four times in a day, that is a trend about to break wider.
LinkedIn: LinkedIn News
For B2B businesses, LinkedIn News surfaces trending professional topics and industry discussions. Following the right industry voices and engaging with their posts gives you an early view of what is about to matter in your sector.
Go Beyond the Obvious with Social Listening Tools
Platform trend tabs only show you the surface. Social listening tools dig into what people are actually saying about your brand, your competitors, and your industry, across every platform at once.
Hootsuite Insights tracks keywords, hashtags, and mentions across channels, giving you a broader read on what is trending among your specific audience rather than the general public. BuzzSumo shows the most shared content for any keyword, which is useful for spotting what format and angle is working before you commit to your own version. Brandwatch goes deeper still, scanning social platforms, blogs, and news sites to catch emerging trends before they reach the mainstream.
None of these tools are free, so weigh the cost against your marketing budget. A smaller Derbyshire business might get more value from fifteen minutes a day manually checking platform trend tabs than a paid subscription to a listening tool. A growing business with several product lines will likely earn that subscription back quickly.
How one Derbyshire retailer turned trend-spotting into real enquiries
We worked with an independent homeware retailer near Matlock who was posting three times a week with barely any engagement. Once we built trend monitoring into their weekly content planning through our social media support, their reach on Instagram tripled inside two months and enquiries followed. Same products, same budget, better timing.

Follow the People Who Spot Trends Early
Influencers and industry commentators tend to catch trends before they hit the mainstream, because spotting them early is part of their job. Building a Twitter list or a LinkedIn following of the right voices in your sector means trends land in your feed before you go looking for them. Just remember they often have their own reasons for promoting a particular topic, so treat it as a starting point rather than gospel.
Watch What Your Competitors Are Posting
If two or three competitors are suddenly all posting about the same subject, using the same hashtag, or running the same type of offer, that is rarely a coincidence. Tools like Mention or Sprout Social can track competitor activity for you, but a simple weekly scroll through their profiles does most of the job for free. This works especially well for local marketing, where competitor moves in your own town or county tell you more than a national trend ever will.
Ask Your Audience Directly
The most overlooked source of trending topics is the audience sitting right in front of you. Polls and surveys on Instagram, LinkedIn, or X take two minutes to set up and hand you direct insight into what your specific followers care about, not what is trending nationally.
Comment sections do the same job passively. Read what people are asking under your posts and under the popular posts in your niche. I still meet business owners who never read their own comments properly. It is one of the simplest pieces of test and measure work available, and it costs nothing but time.
Bringing This into a Proper BIG12 Strategy
Trend-spotting sits inside the Social Media pillar of our BIG12 framework, the 12-part system I built from 18 years of running marketing for SMBs across the East Midlands. On its own, chasing trends gives you short bursts of reach. Paired with the other 11 pillars, from brand positioning to lead generation to test and measure, it becomes part of a strategy that compounds over time.
Most Derbyshire businesses I speak to are strong in one or two pillars and weak in the rest. That imbalance is usually why trend-driven posts do not convert into enquiries even when they get good reach.

The BIG12 Scorecard takes ten minutes and shows you exactly which of the 12 pillars need attention first.
Take the scorecardThe challenge is never learning. It is doing.
By now you know where to look for trending topics on social media. That was never really the hard part. The hard part is doing it consistently, week after week, alongside everything else running a business demands.
This is the gap I see most often in 18 years of this work. Owners read the guide, get the ideas, and then life gets in the way. The trend tab does not get checked. The competitor scroll does not happen. Three months later, nothing has changed.
That is where having someone else carry the workload makes the difference. Not because the ideas are complicated, but because doing them properly every single week is a job in itself.
