Social media search engine optimisation means making your posts, Reels, and TikToks findable when people search inside social platforms. And people are searching. According to a 2026 Adobe Express report, 49% of US consumers have now used TikTok as a search engine. Among Gen Z, that figure rises to 65%. The same behaviour is growing on Instagram, where Reels and posts are increasingly surfaced through keyword search rather than hashtags alone. For SMEs, this changes how you should think about every piece of content you post. You are no longer just posting for your followers. You are publishing for anyone searching your topic on that platform.
What Social Search Actually Means
Social search is when someone types a query into TikTok, Instagram, or YouTube the same way they would type it into Google. ‘Best coffee shop Newcastle.’ ‘How to style a bob.’ ‘Electrician near me.’ The platform then serves results based on what it finds in captions, on-screen text, audio, hashtags, and engagement signals.
This is different from how social media used to work. A few years ago, discovery happened through hashtags and the algorithm’s For You page. Now, platforms are actively building search features. TikTok shows search suggestions mid-scroll. Instagram surfaces keyword results in its Explore tab. Google itself is pulling TikTok and Reels into its own search results.
If your content answers a question someone is actively searching, you have a much better chance of reaching them than if you are relying on the algorithm alone.
Why This Matters for Newcastle Businesses
Most social media advice for SMEs focuses on posting consistently and engaging with followers. That still matters. But social search adds a second layer: discoverability by people who do not follow you yet.
A Newcastle restaurant that captions a Reel ‘Sunday roast Newcastle’ is findable by anyone searching that phrase on Instagram. A tradesperson who titles a TikTok ‘how to bleed a radiator’ could surface for thousands of searches a month. The content does not need to go viral. It needs to match what someone is looking for.
This is where social media and SEO start to overlap. The skills are the same: understanding what your audience searches for, then creating content that answers those queries clearly.
How to Optimise Your Content for Social Search
You do not need to overhaul your content strategy. A few adjustments to how you write captions, title your videos, and structure your posts will make a noticeable difference.
Start with what your audience searches for
Open TikTok or Instagram and type a word related to your business. Look at the autocomplete suggestions. Those are real searches. ‘Wedding florist’ might autocomplete to ‘wedding florist budget,’ ‘wedding florist Newcastle,’ or ‘wedding florist autumn.’ Each of those is a content idea and a keyword.
Put keywords where the platform can read them
On TikTok, that means your caption, your on-screen text, and your spoken audio. TikTok’s algorithm reads all three. On Instagram, focus on your caption and any text overlays on your Reels. For both platforms, front-load the keyword. Do not bury it at the end of a paragraph.
Write captions like mini answers
If someone searches ‘how to clean suede shoes’ and your caption says ‘here is how to clean suede shoes in under two minutes,’ you match the intent perfectly. Short, clear, specific. Think of your caption as the answer to a question, not a clever one-liner.
Use hashtags as supporting signals, not the main strategy
Hashtags still help, but they are no longer the primary discovery tool. Two to five relevant hashtags that describe the content are better than thirty generic ones.
Say the keyword out loud in your video
TikTok and Instagram both transcribe audio. If you say the keyword in your video, the platform picks it up as a relevance signal. This is especially useful for Reels and TikToks where the visual content alone does not make the topic obvious.
A Simple Social Search Checklist
Before you hit publish on your next Reel, TikTok, or post, check these five things. Does the caption include the main keyword in the first line? Is there on-screen text that reinforces the topic? Have you said the keyword in the audio? Does the content answer the query someone would search? Have you added two to five relevant hashtags?
That is it. No specialist tools. No complicated setup. Just a habit of thinking about search intent every time you create content.
Start With Five Posts
You do not need to optimise everything overnight. Pick five topics your customers ask about regularly. Create one post for each, optimised using the steps above. Track which ones get discovered through search (TikTok and Instagram both show how viewers found your content in their analytics).
