Podcast Hashtags: A Practical Guide for UK Brands

Podcast hashtags are topic labels you add to social posts and clips so people searching a subject can find your episodes. They work hard on Instagram, LinkedIn, TikTok and YouTube, where clips travel, and they matter far less inside Apple Podcasts or Spotify, where your title and description do the ranking.

Most founders treat hashtags as an afterthought and paste the same tired list under every clip. That habit costs reach. This guide shows you which tags to pick, how many to use per platform, and how to build a set that pulls the right listeners toward your show.

Key Takeaways

• Hashtags help discovery on social platforms. They do very little inside podcast apps like Apple Podcasts and Spotify.
• Mix three types: niche topic tags, industry tags and one branded tag unique to your show.
• Instagram allows up to 30 per post, but 5 to 10 relevant tags read better and perform fine.
• LinkedIn rewards restraint. Stick to 3 to 5 tags that match the post subject.
• Broad tags like #podcast bury you. Specific tags reach a smaller, warmer audience.
• A branded hashtag gathers every clip and guest mention in one searchable place.
• Refresh your list every quarter. Tag popularity shifts and stale sets go stale fast.

What Podcast Hashtags Actually Do

A hashtag turns a word into a clickable filter. Tap #b2bmarketing and you see a feed of posts tagged that way. When you add relevant tags to a podcast clip, you place that clip inside those feeds, so a person exploring the topic can stumble onto your episode without ever having heard of your show.

That reach lives on social. Inside podcast directories the mechanics differ. Apple Podcasts and Spotify rank shows on title, category, description keywords and listener behaviour. Dropping hashtags into your episode notes there does almost nothing. Save your tagging effort for the clips you push out on Instagram, LinkedIn, TikTok and YouTube.

For a UK founder building authority, this distinction saves hours. You want hashtags on the short vertical clip going to Reels, and clean keyword-rich copy in the show notes that Apple reads.

The Three Types of Podcast Hashtags to Use

Build every hashtag set from three ingredients. Balance matters more than volume.

Niche topic tags describe the exact subject of the episode. If your guest talks about pricing strategy for agencies, tag it #agencypricing or #agencygrowth rather than #business. These smaller tags carry less traffic, and the traffic they carry is far more likely to care.

Industry and audience tags widen the net to your sector. #ukbusiness, #foundersuk, #saasmarketing. They sit between broad and niche and catch people who follow the field without knowing your show.

One branded tag ties the whole catalogue together. Use your podcast name with the spaces removed. Every clip, every guest repost, every listener shout-out lands in one feed a new fan can scroll through. Print it in your bio and say it out loud on the episode.

Skip the vanity tags. #podcast, #podcasting and #newepisode reach millions of posts and rank you nowhere. They signal effort to no one and pull no listeners.

How Many Hashtags Per Platform

Each platform has its own tolerance. Match the tool to the room.

Instagram permits up to 30 hashtags per post per its own posting rules, and stuffing all 30 in tends to read like spam. A tighter set looks intentional and performs just as well. LinkedIn punishes clutter, so keep it short and topical. On YouTube, only the first three hashtags in your description show above the video title, so front-load your best ones.

How to Research Podcast Hashtags That Work

Guessing wastes reach. Spend twenty minutes on research per show and reuse the set across a season.

Start on the platform itself. Type a candidate tag into the Instagram or TikTok search bar and read the post count. A tag with 5,000 to 500,000 posts sits in the sweet spot. Big enough to have an audience, small enough that your clip does not vanish in seconds.

Study three shows in your field that already win attention. Read the tags under their most-viewed clips. Borrow the relevant ones and drop the off-topic filler.

Check what your guests and listeners already say. If your audience talks about #fractionalcfo or #ecommerceuk, meet them there. The language your buyers use beats any tag a marketer invents in a boardroom.

Keep a running document of tested sets per topic. Over a season you build a library you can pull from in seconds, and you can see which sets earned the most saves and shares.

Common Podcast Hashtag Mistakes

A few habits quietly cap your reach.

Reusing one giant block under every post trains the algorithm to see repetition, and repetition reads as low effort. Vary the set to fit each episode.

Chasing only the biggest tags feels productive and delivers nothing. Volume without relevance is noise.

Ignoring your branded tag means your clips never gather in one place, so a new fan has no easy trail to follow through your back catalogue.

Forgetting to refresh leaves you tagging with sets that peaked a year ago. Review the list each quarter and swap out the tags that stopped pulling.

The brands that build real authority through podcasting treat every clip as a distribution asset, and hashtags are one small lever inside a bigger content engine.

Turning Hashtags Into a Repeatable System

One clean set of hashtags will not build a demand engine on its own. It sits inside a wider rhythm: strong episodes, sharp clips, consistent posting and a plan for where each piece travels. Hashtags decide who finds the clip. The clip decides whether they stay.

Founders who try to run this alone usually stall at the clip stage, where the editing, captioning and posting eat the week. That is the exact point where a production partner earns its keep.

If your show has good content trapped behind poor distribution, the fastest path forward is a proper audit of what you already have. Book a Discovery Audit and we will map where your podcast is leaking reach and how to fix it inside 100 days.

FAQ

How many podcast hashtags should I use? It depends on the platform. Instagram allows up to 30 per post and a set of 5 to 10 relevant ones tends to read cleaner. LinkedIn works best with 3 to 5. TikTok and YouTube prefer 3 to 6 tightly matched tags.

Do podcast hashtags actually help people find my show? Yes, on social platforms. Hashtags act as topic labels that group your clips with related content, so someone browsing a subject can surface your episode. They carry far less weight inside Apple Podcasts or Spotify, where the show title and description do the ranking.

Should every brand use the same podcast hashtags? No. Broad tags like #podcast put you next to millions of posts and bury you fast. A mix of niche, industry and branded tags gives your episodes a fighting chance of reaching the right listeners.

What is a branded podcast hashtag? A tag unique to your show, such as your podcast name with no spaces. It gathers every clip, guest post and listener mention in one place and makes your back catalogue easy to browse.

Where do I put hashtags on a podcast clip? In the caption on Instagram and LinkedIn, in the caption or on-screen text on TikTok, and in the description or pinned comment on YouTube. Keep them below the hook so they do not clutter the first line.
