A podcast is a series of audio or video episodes published online that people can stream or download, usually through a podcast app or YouTube, and follow so new episodes arrive automatically. For a business, it is a way to share expertise and build a relationship with an audience over many hours of listening.
How a podcast works
Episodes are uploaded to a podcast hosting service, which stores the files and produces an RSS feed. That feed is submitted to directories such as Apple Podcasts and Spotify, which check it for new episodes and deliver them to followers. Many shows also publish a video version on YouTube, which at the time of writing (October 2026) has become one of the main places people watch and listen to podcasts. Google closed its separate Google Podcasts app in 2024 and moved listeners to YouTube Music.
Common formats for business podcasts are interviews with guests, solo episodes in which the host explains a topic, conversations between two regular hosts, and short episodes answering one question each. Episode length should follow the material; there is no standard length listeners expect.
Search engines index the episode pages, show notes and transcripts on your website, and YouTube indexes titles, descriptions and automatic captions. Audio alone is hard to search, so the text around each episode decides how discoverable it is, and a transcript makes the content accessible to people who cannot listen.
Why it matters
Listeners spend far longer with a podcast than with a blog post or a social update, and they often listen regularly while commuting, exercising or working. That builds familiarity and trust, which suits businesses whose customers make considered decisions: B2B services, professional advice, specialist trades and coaching.
Inviting guests is also a networking tool. Interviewing potential partners, clients or respected names in your sector creates relationships and content at the same time, and guests usually share the episode with their own audience.
The honest limitation is effort. A podcast needs planning, recording, editing, publishing and promotion every week or fortnight, and audiences tend to grow slowly. For many small UK businesses, appearing as a guest on established shows reaches more of the right people for far less work than starting a show of their own.
If a podcast carries paid sponsorship or promotes your own products, the ASA’s CAP Code applies to those marketing messages, which must be obviously identifiable as advertising.
Common mistakes
- Starting without a clear audience and subject, so episodes drift between topics and nobody knows who the show is for.
- Poor audio. Listeners forgive basic video but not echo, background noise or uneven volume.
- Publishing episodes with no show notes, transcript or episode page, so search engines find almost nothing.
- Stopping after a handful of episodes, before the show has a chance to find listeners.
- Recording only audio when a simple video version could reach YouTube’s audience.
- Measuring success by downloads alone, instead of the enquiries, relationships and reusable content it produces.
How to act on it
Decide first whether you need your own show or would do better as a guest. If you go ahead, define the listener, the subject and a format you can sustain for at least a year, and record a few episodes before launching so you have a buffer.
Give every episode a page on your site with a summary, key points, links and a transcript. Record video where you can, use YouTube SEO basics for titles and descriptions, and cut short clips for social channels as part of your wider content distribution. Treat each episode as raw material: one conversation can become an article, a newsletter and several posts, alongside your video marketing.
Deciding whether a podcast is worth the time compared with other channels is the kind of question I answer in digital marketing strategy work with UK businesses.
