How to advertise on Killer Stories with Harvey Guillén: what it costs, who buys, and how to book

Killer Stories with Harvey Guillén sells its host-read inventory the way most independent true crime feeds do: direct, quoted per campaign, not off a public rate card. Spotsnow attributes almost all of the show's ads to direct response, close to 97%, which tells you what this feed is for. It's a conversion engine. The top spender, Chime, has run roughly 5 to 6 recent spots, and the roster around it reads like a DTC media plan. For a buyer weighing the show, that mix signals coded offers and trackable URLs, not soft brand lift. Spotsnow estimates all of this from tracked advertiser activity, not audience surveys.

Why Killer Stories is built for host-read direct response

Harvey Guillén hosts and narrates the show, walking listeners case by case through the psychology behind notorious murders. It sits in financial services advertisers' target zone as a true crime feed, and Spotsnow attributes nearly 97% of its ads to direct response. That matters because DR reads live or die on attribution: a promo code, a vanity URL, a spoken offer the listener acts on. Spotsnow estimates the show reaches roughly 580,000 listeners per episode, an estimate rather than an audited count.

The format is the argument here, not the price. Narrative true crime holds attention through the break because the story is mid-arc when the ad lands. A listener leaning into a kidnapping case doesn't skip as fast. That sustained attention is exactly what a host endorsement borrows when Guillén hands off to a sponsor and then straight back into the story.

On engagement, Spotsnow data shows a 4.7 average Apple Podcasts rating across a base in the 26,000 to 30,000 review range. The show's influence is concentrated in the feed and in that rating base rather than spread across social platforms, which is where a DR buyer wants attention anyway: at the point of the read.

Who is advertising on Killer Stories

The roster is a blue-chip DR lineup spanning fintech, hiring software, streaming, and retail. Recognizable names in the recent pool include Shopify, Chime, Mint Mobile, Disney+, and SoFi.

The anchor advertisers, broken down

Chime

Chime is a fee-light neobank aimed at everyday Americans. Spotsnow data shows it running roughly 5 to 6 recent spots, the deepest repeat commitment among the anchors, with estimated total spend over $100K. Spotsnow classifies the activity as direct response. A young, mostly US audience managing everyday money is exactly who a no-fee banking app wants in its funnel.

Zip Recruiter

Zip Recruiter is an employment marketplace that matches employers with candidates. Spotsnow data shows roughly 2 to 3 recent host-read slots and estimated total spend over $50K, classified as direct response. A working-age, US-heavy audience is a natural pool of both hirers and job seekers, which is why the read leans on the everyday-hassle hook.

Shopify

Shopify sells the e-commerce platform behind millions of online stores. Spotsnow data shows roughly 4 recent host-read slots and estimated total spend over $40K, classified as direct response. The show's younger, entrepreneurial, side-hustle-minded listeners are the exact people who start a store on a whim after a good read.

An awareness outlier: Tremfya

Not everyone in the feed buys for clicks. The pharma brand Tremfya runs produced spots, not host reads, which shows a straight awareness objective can also fit here even though DR is the show's core. It's the exception that proves the rule.

All spend figures are Spotsnow estimates.

Why true crime brands cluster here

True crime listeners commit. They follow a case for forty minutes, they rate the show 4.7, and they trust the voice walking them through it. That trust is the asset a DR advertiser rents. When Guillén reads a code for a bank or a hiring tool, the endorsement carries the same authority the storytelling built minutes earlier. Pair that with an audience that skews young, strongly female, and US-based, in the years where people open first checking accounts, change jobs, and start businesses, and the fintech-and-hiring cluster stops looking like a coincidence. The advertisers are buying the moment of trust plus a moment of life-stage intent, priced by the response they can track back to a coded URL.

How your ad could sound

The Zip Recruiter read is a clean template for this feed. What works: it opens on a relatable, personal frame (running errands, wishing for an extra hand), drops a trackable vanity URL at ziprecruiter.com/killers, backs the pitch with a specific stat about employers finding a quality candidate within the first day, and hands off naturally straight back into the Stan Alpert story. The listener barely feels the seam.

Two things to tighten. The offer path is spoken as a slash-URL ("Try for free at ziprecruiter.com slash killers"), which is easy to mishear on earbuds; a code plus a URL gives the ear a backup. And "try it for free" repeats without saying what free actually includes or setting a deadline, so there's no urgency pulling the listener to act now instead of later.

What makes a show like this convert

1. The format holds attention through the break. A mid-story ad in a narrative true crime feed gets heard, not skipped, because the case isn't resolved yet.
2. Host credibility transfers to the offer. Guillén's endorsement borrows the trust the storytelling built, which is why a 4.7-rated feed reads well for DR.
3. The audience matches the buyers. A young, mostly US, strongly female audience in prime money-and-career years lines up with fintech, hiring, and retail offers.
4. Repeat buying proves the math. Chime coming back for roughly 5 to 6 spots is a brand that saw its coded response and re-upped.

Killer Stories in a nutshell

The audience skews young, strongly female, and US-based, with the engagement of a 4.7-rated true crime following. The brands already buying, Chime, Zip Recruiter, and Shopify among them, run mostly host-read direct response with coded URLs. The show is sold direct and quoted per campaign rather than off a rate card. If your objective is trackable response, this feed fits; if you only want brand association, the produced-spot lane exists but isn't the show's strength.
