Hashtag Strategy: A Practical Guide for UK SMEs

Most small businesses treat hashtags as an afterthought. They paste the same block of generic tags under every post and wonder why nothing changes. Used with a plan, hashtags are still one of the cheapest ways to reach people who do not follow you yet, whether you run a café in Shoreditch, a Pilates studio in Clapham or an independent shop in Camden.

This guide pulls together what actually works: how to set a goal, research the right tags, build tiered sets for each platform, and measure the results. It also covers sector-specific advice for hospitality, fitness, beauty, retail, property and finance.

What hashtags still do

Hashtags are labels. They tell a platform what your post is about, which helps it show your content to people interested in that topic. They also make your posts findable when someone searches a tag.

They have changed, though. The days of stuffing 30 random tags into a caption are over. Platforms now lean far more on content quality and interest signals, and they reward relevance over volume. Think of hashtags as distribution support for good content, not a replacement for it.

Step 1: Set a goal first

Before you search for a single tag, decide what you want hashtags to do. Common goals are:

• Reaching new local customers
• Building a community around your brand
• Promoting a seasonal offer or event
• Positioning your business in a professional conversation, for example on LinkedIn

Write the goal down in one sentence. A Manchester gym chasing new members needs different tags from a boutique hotel promoting midweek breaks.

Step 2: Understand the main types of hashtag

A strong strategy mixes several types.

Broad tags have millions of posts, such as #fitness, #food or #fashion. They signal your topic but your post disappears in seconds. Use one or two at most.

Mid-size and niche tags are more specific, such as #LondonFitness, #BoutiqueGym or #SustainableFashionUK. Competition is lower and the audience is more engaged. These should form the core of most sets.

Location tags are vital for any business with a physical site. Layer them from hyperlocal to wider: #ShoreditchEats, then #EastLondonFood, then #LondonEats. Local tags often have less competition and higher buying intent.

Branded tags are unique to you, such as your business name or a campaign line like #TrainWithUs. They build a searchable archive of your content and make user-generated content easy to find.

Seasonal and trending tags tie you into wider conversations, such as #DryJanuary, #MothersDayUK or #ChristmasGifts. Use them only when they genuinely fit your post.

Step 3: Research tags your customers actually use

Good research takes about 30 minutes and saves hours later.

Search inside the platforms. Type a keyword into Instagram or TikTok search. Note the related tags suggested and how many posts each one has. As a rough guide, tags with somewhere between 10,000 and 500,000 posts often give small businesses the best balance of reach and visibility.

Study competitors, but do not copy blindly. Look at which tags appear on their best-performing posts. Then look for gaps. If every gym nearby uses #LondonFitness, there may be room for #SouthLondonStrength.

Mine customer language. Read your reviews, comments and the posts customers make when they tag your location. The words they use often point to tags your competitors have missed.

Check every tag before you use it. Open the tag page and scroll the recent posts. If it is full of spam, unrelated content or shows a content warning, avoid it. Some tags are restricted because of misuse, and using them can limit your reach.

Use tools if they help. Instagram and TikTok search are free and often enough. Tools such as Flick, Hashtagify, RiteTag, Later and Metricool can speed up research and track performance. Google Trends is useful for spotting seasonal peaks, for example when searches for boutique hotels in London rise.

Step 4: Build tiered sets for each platform

Group your researched tags into ready-made sets so you are not starting from scratch every time. A simple starting template for one post:

• 1 to 2 broad tags
• 3 to 5 niche or community tags
• 2 to 3 location tags
• 1 branded tag

Then trim to suit each platform.

Instagram. Instagram's own advice has moved firmly towards a small number of highly relevant hashtags, and the platform has changed how many it allows over time. Plan for 3 to 5 strong tags rather than a long list. Caption or first comment both work, so pick what keeps your caption readable.

TikTok. Hashtags work alongside TikTok's interest-based algorithm and behave a lot like search terms. Use 3 to 5 tags that clearly describe the video. Active community tags such as #FoodTok or #GymTok can help when they fit. Pair tags with strong hooks and current formats.

LinkedIn. Use 1 to 3 professional, topic-specific tags. They act more like categories than discovery tools.

Facebook and X. Hashtags carry little weight on Facebook, so one or two is plenty. On X, one or two relevant tags can help around live events and trending topics.

Pinterest. Pinterest works like a search engine. Focus on descriptive keywords in your pin titles and descriptions.

Step 5: Create a hashtag bank

A hashtag bank is a saved library of tested tags, organised by theme. Keep it in a Google Sheet or Notion page with columns for hashtag, platform, tier, post count, and notes on performance.

Build separate sets for each type of content, because each format attracts different behaviour:

• Product or menu posts
• Behind-the-scenes content
• Customer stories and reviews
• Offers and seasonal promotions
• Educational posts

A transformation video suits journey-focused tags. A hotel room reveal suits aspirational ones. Rotate between two or three versions of each set and swap a few tags each time. Pasting the identical block on every post looks repetitive to both platforms and people.

Share the bank with anyone who posts for you, so whoever is on social media that day works from the same playbook. It also keeps your brand presentation consistent, which matters as much as the tags themselves.

Step 6: Promote your branded hashtag

A branded tag only works if people use it. Keep it short, easy to spell and unique enough that searching it returns your content. Then put it everywhere: your bio, printed menus, receipts, table cards, gym walls, packaging and email footers. Ask customers to use it when they share their visit, class or purchase, and reshare the best posts with permission. A dedicated tag for a challenge, programme or weekly feature such as a Sunday roast can build real community.

Sector tips

Hospitality

Lead with location and experience. Combine neighbourhood tags with cuisine and occasion tags, such as #ShoreditchEats, #SundayRoastLondon or #WeekendBreak. Plan around menu launches, seasonal events and local festivals. Guest posts are powerful in this sector, so make your branded tag visible at the table. For video, see our guide to TikTok for London restaurants and bars.

Fitness

Community is everything. Use tags that reflect your training style and area, such as #HIITLondon or #PersonalTrainerLondon. Early January and the run-up to summer bring natural spikes in interest, so prepare sets in advance. Create a tag for challenges so members can find each other. Our fitness and health marketing team works with gyms and studios on exactly this.

Beauty and wellness

Pair location tags with treatment tags, such as #LondonFacials with #AntiAgeingSkincare. Lean into seasonal moments: Valentine's Day pamper packages, summer skin, festive gifting. Pinterest and TikTok both reward descriptive tags for routines and treatments. See our beauty and wellness marketing page for wider support.

Retail

Be specific about the product. #HandmadeCandles beats #Candles. Use your location to reach people who can walk in, and prepare seasonal sets two to three weeks before key moments such as Christmas, Mother's Day, Back to School and Black Friday, so posts have time to gain traction.

Property and finance

Your audience is cautious and making big decisions, so generic tags like #money or #property will not cut through. Match tags to real concerns: #FirstTimeBuyerUK, #BuyToLet, #LondonLandlord, #CommercialProperty. LinkedIn is usually the most valuable platform here. Remember that social posts about regulated financial products can count as financial promotions under FCA rules, so hashtags and captions need the same compliance care as any other ad. Our property and finance marketing team can help.

Measure, then refine

You cannot improve what you do not track. Use a professional or business account so you can see post-level data.

• Instagram Insights shows where impressions came from, including hashtags.
• TikTok analytics shows traffic sources, including search and the For You feed.
• LinkedIn analytics shows reach and engagement by post.

Look beyond likes. Track reach from non-followers, profile visits, saves, follows and, most importantly, enquiries, bookings or sales. Review every month: drop tags that bring nothing, test replacements and build more sets around what works. Do a fuller refresh every quarter, because tags can become oversaturated or hijacked by spam.

Common mistakes to avoid

• Using only huge tags, so your post is buried immediately
• Adding popular but irrelevant tags, which attracts the wrong audience
• Pasting the same set on every post
• Skipping location tags when you rely on local customers
• Never checking a tag before using it
• Ignoring your analytics

FAQ

How many hashtags should I use?

Fewer than you think. On Instagram and TikTok, 3 to 5 highly relevant tags is a sensible default. On LinkedIn use 1 to 3, and on Facebook and X one or two.

Are hashtags dead?

No, but they matter less than they used to. Content quality and relevance drive reach now. Good hashtags help platforms understand your post and help people find it through search.

Should I put hashtags in the caption or the first comment?

Either works on Instagram. Choose the option that keeps your caption clean and test both over a few weeks.

How often should I update my hashtag sets?

Review performance monthly and refresh your bank every quarter. Always prepare seasonal sets a few weeks before the moment they relate to.

Do I need paid tools?

Not to start. Native search and insights are enough for most small businesses. Paid tools save time once you post daily across several platforms.

Start with one platform

A hashtag strategy does not need to be complicated. Pick the platform where your customers spend the most time. Set one goal, research 20 to 30 tags, build three sets for your main content types, and test them on your next ten posts. Review the data, cut what does not work and repeat. Combine that with strong content and steady social media management, and hashtags become a reliable free source of new customers.
