How to follow podcast guests across shows

A great guest can ruin you for the rest of your queue. You catch a one-off appearance on a show you barely listen to, and suddenly you want everything that person has ever said into a microphone. The problem: podcast apps weren't built for that. They follow shows, not people.

This guide walks through six practical methods for tracking a guest across every podcast they appear on, plus what to do when the guest is so interesting you want to hear them in real time.

TL;DR

• Podcast RSS feeds don't tag guests, so apps can't filter by person on their own
• Listen Notes, Podchaser, and Apple Podcasts all expose guest searches in different ways
• AI summaries and transcripts can surface a guest you didn't know was on an episode
• Newsletter sign-ups from the guest's own site usually announce upcoming appearances first
• A simple Google Alert handles the rest

Why is this so hard in the first place?

Podcasts are distributed via RSS, and the RSS spec has nothing to say about guests. A show's feed lists episodes, titles, descriptions, and timestamps. Whether the description happens to mention "with guest Cal Newport" is up to the producer. Some shows tag every guest cleanly in episode titles. Most don't.

That gap is why your podcast app probably can't help you here. Apple Podcasts, Spotify, Overcast, and Pocket Casts all index by show because that's what the underlying data supports. The directories that index people instead, like Podchaser and Listen Notes, do it by manually parsing show notes and crowdsourcing tags. It works, but it's a separate workflow from the app where you actually listen.

Once you accept that guest discovery lives outside your podcast app, the methods below get a lot easier.

Method 1: Use a third-party guest search

The fastest way to find every podcast a guest has appeared on is a search engine that already indexed them.

Listen Notes runs a "people" search that returns episodes featuring a given guest. Type the name, hit search, and you get a chronological list of episodes across thousands of shows. It's free, it's fast, and the results link out to whichever app you prefer.

Podchaser does the same thing but with deeper credit data, including roles like host, producer, and guest. Their people pages are more polished, and you can follow a person to get notified when they appear on a new show. Following requires a free account.

For one-off lookups, both work. If you find yourself doing this weekly, follow the person on Podchaser so the new appearances come to you.

Method 2: Apple Podcasts and Spotify search

Both major listening apps index episode titles and show notes, even though they don't have a dedicated "guest" filter. Searching a person's full name turns up episodes where they're the headline guest, because most shows put the guest's name in the title.

In Apple Podcasts, search the name and switch the results tab from "Shows" to "Episodes." Spotify behaves the same way. The results are noisy because any mention pulls in, but you can scan the show titles fast and add the relevant episodes to your queue.

This works best for guests who appear on the kinds of shows that put names in titles, which is most interview-format shows. It works less well for panel shows where a guest is one of four voices.

Method 3: Newsletter sign-ups from the guest themselves

Most authors, founders, researchers, and creators with a publishing habit have a newsletter. The newsletter is where they announce their podcast appearances first, usually a week before the episode drops.

Sign up. Most newsletters have a one-line "where I've been this month" section that lists every podcast they recorded for. You'll know before the episode is in any feed.

This is the highest-signal source by a wide margin. If you only do one thing on this list, do this. It also tends to surface guest appearances on smaller, more specialised shows that don't show up in big directory searches.

Method 4: Google Alerts and RSS searches

A Google Alert on a person's name plus the word "podcast" sends you an email whenever a new episode mentions them. Set it to "as it happens" if you want fast turnaround, or "once a day" if you want to batch.

To set one up, go to google.com/alerts, enter "Cal Newport" podcast (with the quotes), set the language and frequency, and save. The quotes matter. Without them you get every result that contains both words anywhere on the page.

Two caveats. Google Alerts misses paywalled content and some major podcast networks that block crawling. And it only catches mentions on web pages that Google has crawled, so very fresh episodes may take a day or two to surface.

Method 5: The guest's own website appearances page

Many frequent guests maintain an "appearances" or "media" page on their personal website. It usually lists every podcast, talk, and interview going back years. This is the canonical version of the truth: they know exactly where they've been, because they were the one being interviewed.

Search the person's name plus "appearances," "media," "press," or "podcast" and you'll usually find it on their site. Bookmark the page. Many people update it monthly.

This works especially well for academics, authors, and public figures with media training. It works less well for guests who appear on podcasts casually or as part of their day job.

Method 6: Use AI summaries and transcripts to catch guests you didn't know were there

The frustrating discovery is the one you almost missed. You're scrolling your queue, you skip an episode of a show you don't usually listen to, and three weeks later you find out your favourite guest was on it. The episode title didn't mention them. The show notes buried them in paragraph three.

This is where transcript and summary tools earn their keep. If your app surfaces an AI summary of every episode (Podtastic does, and so do a few others), the guest's name shows up at the top of the summary even when the show notes hide it. You can scan summaries across your queue in a few minutes and catch guests you'd otherwise miss.

For shows you don't subscribe to, our guide to using podcast transcripts walks through how to search transcripts directly. A name that appears six times in a transcript is almost always a guest, even if the title doesn't say so.

How to set up a guest-tracking system that actually sticks

Picking one method works fine for one or two favourites. If you regularly find yourself wanting to follow more guests, layer the methods.

Here's a system that scales without becoming a chore:

• Tier 1, the people you'd drop everything for. Newsletter sign-up. Podchaser follow. Google Alert. You'll catch every appearance within a day.
• Tier 2, the people you'd queue up if it landed in front of you. Podchaser follow only. The weekly or monthly digest is enough.
• Tier 3, one-off curiosity. Listen Notes search when you remember. No ongoing tracking.

Most listeners have around a dozen Tier 1 guests, give or take. Tier 2 expands as you discover more interview-heavy shows. Tier 3 is the long tail and doesn't need a system.

What if the guest hosts their own podcast?

If a guest you keep enjoying ends up hosting their own show, that's a different problem with a much easier solution: subscribe directly. Most repeat guests eventually start their own podcast, especially in fields where their name is the brand.

When that happens, you stop needing the guest-tracking system for that person and switch to following their main feed. Your podcast app handles the rest. For finding shows generally, see our guide to finding new podcasts.

Frequently asked questions

Is there a podcast app that lets me follow people directly?

Not in the mainstream players, no. Apple Podcasts, Spotify, Pocket Casts, and Overcast all index shows, not people. Podchaser comes closest because it has people pages and follows, but it's a directory and review site, not a fully featured player. The closest workaround is to combine an app you like for listening with Podchaser or Listen Notes for guest tracking.

How do I find out a guest's name if the episode didn't tell me?

Open the show notes. If they're blank, search the episode title plus "guest" on Google. If the show has a transcript, the guest is usually introduced by name in the first two minutes. If you're using an app with AI summaries, the guest is named at the top of the summary regardless of the show notes.

What about returning guests I want to keep up with on one specific show?

You don't need this whole system for that. Most podcast apps let you search within a show's back catalogue. Search the guest's name in the show's episode list and bookmark or queue every match. If the show is one you subscribe to, you'll see new appearances automatically.

Can I get email alerts when a specific guest appears on any podcast?

Yes, two ways. The cleanest is a Podchaser follow, which sends you a notification when a new episode tagged with that person publishes. The catch-all is a Google Alert on the person's name plus "podcast." Used together, you'll catch nearly every appearance within 24 to 48 hours of release.
