Downloads Count Requests, Not Listeners<\/h2>\n      <p class=\"mp-p\">A download happens when a device pulls an episode file from a server. That pull can be automatic. It can happen while a listener is asleep, their phone charging, auto-syncing every show they subscribed to three years ago and never opened again.<\/p>\n      <p class=\"mp-p\">The Interactive Advertising Bureau sets technical standards that filter out bots and duplicate server requests from raw download figures. But even IAB-certified numbers represent compliant file requests, not verified human listens. There is a gap between those two things, and no <a href=\"\/blog\/podcast-media-kit-for-sponsors\/\" rel=\"noopener\" target=\"_blank\">podcast media kit<\/a><!-- verify slug before publishing --> flags it.<\/p>\n      <p class=\"mp-p\">If 30% of reported downloads on a show are passive auto-syncs that never played, your actual cost per thousand engaged listeners is not what the rate card shows. You are paying for an audience that was never there.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">Treat download figures as a ceiling, not a count. Every metric that follows in this guide gets you closer to the real number underneath that ceiling.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"completion-rate-who-heard-the-ad\">2. What Does Episode Completion Rate Tell You?<\/h2>\n      <p class=\"mp-p\">Completion rate is the percentage of listeners who reach a defined threshold in an episode, typically 80% of total runtime. It is the most predictive engagement signal available in podcast advertising, and it is consistently under-requested by brands.<\/p>\n      <p class=\"mp-p\">A listener who reaches the 80% mark of a 45-minute episode has given 36 uninterrupted minutes of focused attention. They are not skimming a feed. They are not toggling between tabs. They are in it. And if your ad runs mid-roll, they heard it during the most sustained stretch of attention they gave anything that day.<\/p>\n      <p class=\"mp-p\">According to Gitnux&#8217;s 2026 marketing statistics report, 72% of listeners complete episodes containing host-read ads, with purchase intent running 2.5x higher than with scripted placements. That is not a channel metric. It is an attention quality signal. Attention quality is what converts.<\/p>\n      <h4 class=\"mp-h4\">What each completion threshold means for your campaign<\/h4>\n      <p class=\"mp-p\">Above 70% means your mid-roll reaches a listener who committed fully to the episode. That is the audience your ad is priced against. Between 50% and 65% is acceptable for awareness goals, where reach matters more than sustained attention. Below 50% means a meaningful share of the audience has already left before your ad plays, regardless of what the rate card says.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">Before committing budget to any show, request episode completion rate pulled directly from their hosting analytics or Spotify for Podcasters dashboard. If the show cannot produce this number, ask why before proceeding.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"cpm-not-what-rate-card-says\">3. Your CPM Is Not What the Rate Card Says<\/h2>\n      <p class=\"mp-p\">Once you have completion rate, you can calculate what you are actually paying per engaged listener. The published CPM does not include this adjustment. You have to run it yourself.<\/p>\n      <div class=\"mp-formula\">Adjusted CPM = (Published CPM &#247; Completion Rate) &#215; 100<\/div>\n      <p class=\"mp-p\">A $30 CPM on a show with 70% completion costs $43 per 1,000 listeners who stayed through your ad. That same $30 on a 40% completion show costs $75 per 1,000 listeners who actually heard it. The media kit shows you the first number. The second is your real cost.<\/p>\n      <p class=\"mp-p\">This formula also changes how you compare shows against each other. A niche show charging $50 CPM with 78% completion is a fundamentally different buy than a broad show at $22 CPM with 44% completion. Raw CPM comparison hides that entirely.<\/p>\n      <h4 class=\"mp-h4\">What completion rate data to request specifically<\/h4>\n      <p class=\"mp-p\">Ask for completion rate figures specific to mid-roll episodes, not the show average. Some shows have strong early-episode retention but weaker mid-roll hold. Those two numbers diverge more than networks typically volunteer.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">Run the adjusted CPM calculation on every shortlisted show before you compare prices. Put both numbers in your evaluation sheet: the published CPM and the engagement-adjusted CPM. Then compare.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"set-cpa-ceiling-before-negotiation\">4. Set Your CPA Ceiling Before Any Negotiation<\/h2>\n      <p class=\"mp-p\">CPM tells you what you paid per thousand impressions. Cost per acquisition tells you what you paid to get one customer. Only one of those tells you whether the campaign made money.<\/p>\n      <p class=\"mp-p\">Every podcast media buy should start with your CPA ceiling. That is the maximum you can pay to acquire a customer while still running the campaign profitably. You build it from your margin, not from the show&#8217;s rate card. If you have not set that number before opening any negotiation, the rate card becomes the benchmark by default. That is not a measurement strategy.<\/p>\n      <p class=\"mp-p\">The math is straightforward. If your product sells for $250 and your gross margin is 55%, you net $137.50 per sale. A CPA ceiling of $60 gives you a 2.3x return. Any show that cannot plausibly deliver at or below $60 per acquisition, based on its audience size and completion rate, is priced too high for your goal regardless of how the download count looks.<\/p>\n      <h4 class=\"mp-h4\">How to project CPA before you buy<\/h4>\n      <p class=\"mp-p\">Use 0.5 to 1% of engaged listeners as your conservative conversion estimate for new shows. Engaged listener count equals downloads per episode multiplied by completion rate.<\/p>\n      <p class=\"mp-p\">If a show has 10,000 downloads per episode and 70% completion, your engaged audience is 7,000. At a 1% conversion estimate, you expect roughly 70 actions. At a $60 CPA ceiling, your maximum episode budget is $4,200. If the show asks $1,800, you have headroom. If they ask $5,000, the math does not work.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">Calculate your CPA ceiling before you contact any show. Write the number down. Every rate card negotiation runs through that filter first.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"lock-success-definition-before-signing\">5. Lock Your Success Definition Before Signing Anything<\/h2>\n      <p class=\"mp-p\">Running a campaign without pre-defined metrics is how brands end up interpreting data selectively after the fact. The results come back and the conversation becomes about what the numbers might mean rather than whether they hit the mark. A KPI scorecard removes that conversation entirely because the mark was set before the first episode aired.<\/p>\n      <p class=\"mp-p\">Fill in every row of this scorecard before you sign anything. Not after you see the data.<\/p>\n      <div class=\"mp-table-wrapper\">\n        <table class=\"mp-table\">\n          <thead>\n            <tr>\n              <th>Metric<\/th>\n              <th>Your Target<\/th>\n              <th>Tracking Method<\/th>\n              <th>Window<\/th>\n            <\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td>Episode completion rate<\/td><td>Above 70%<\/td><td>Hosting analytics<\/td><td>Per episode<\/td><\/tr>\n            <tr><td>Adjusted CPM<\/td><td>Recalculate vs published<\/td><td>Downloads &#215; completion<\/td><td>Per episode<\/td><\/tr>\n            <tr><td>Cost per acquisition<\/td><td>Your ceiling<\/td><td>Codes + pixel + survey<\/td><td>60 days<\/td><\/tr>\n            <tr><td>Promo code conversion rate<\/td><td>0.5 to 1% of engaged listeners<\/td><td>Unique code per show<\/td><td>30 days<\/td><\/tr>\n            <tr><td>Brand recall lift<\/td><td>10+ points over control<\/td><td>Third-party survey<\/td><td>Post-campaign<\/td><\/tr>\n            <tr><td>Attribution coverage<\/td><td>3+ methods active<\/td><td>Pre-launch checklist<\/td><td>Launch day<\/td><\/tr>\n            <tr><td>Renewal threshold<\/td><td>CPA within 20% of ceiling<\/td><td>Blended attribution<\/td><td>60 days<\/td><\/tr>\n          <\/tbody>\n        <\/table>\n      <\/div>\n      <p class=\"mp-p\">This document becomes the reference for every conversation about the campaign.

Set Up Attribution Before Episode One Airs<\/h2>\n      <p class=\"mp-p\">In a 2026 survey of marketing managers with budgets over $1 million, 64% named attribution as their biggest challenge with podcast campaigns. That is not a technology problem. Attribution tools have improved significantly. It is a timing problem. Most brands arrive at the measurement question after the campaign has already run.<\/p>\n      <p class=\"mp-p\">There is no pixel firing in real time when a listener hears your ad. No link to click at the moment of exposure. A listener hears your message during a morning commute, thinks about it for three days, and converts Thursday afternoon from a different device. That conversion exists. Whether your measurement setup captures it depends entirely on what you built before the first episode aired.<\/p>\n      <h4 class=\"mp-h4\">The four attribution methods and what each captures<\/h4>\n      <ul class=\"mp-ul\">\n        <li><strong>Unique promo codes:<\/strong> Each show gets its own code so you know exactly which show drove a conversion. The limitation is undercounting: codes typically capture 30 to 60% of true podcast-driven conversions because many listeners buy without using any code at all. They are the floor of what actually converted, not the ceiling.<\/li>\n        <li><strong>Vanity URLs:<\/strong> A show-specific slug on your domain tracks clicks and landing page visits. It captures more of the listener journey than codes alone but misses purchases that arrive days later through a direct search or a saved browser tab.<\/li>\n        <li><strong>Pixel-based attribution:<\/strong> Platforms such as Podscribe or Claritas match your converted customers against listener IP data to identify which podcast episodes they heard before buying. This captures the listener who searched your brand directly with no code used, and is now the standard method for campaigns running at scale.<\/li>\n        <li><strong>Post-purchase surveys:<\/strong> Ask customers one question at checkout: where did you hear about us? With podcast listed as an option alongside show names, surveys surface conversions that every other method missed. According to AD Results Media&#8217;s 2026 podcast advertising guide, brands using all four methods together attribute two to three times more conversions than those relying on codes alone.<\/li>\n      <\/ul>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">Treat attribution setup as a launch prerequisite. If a show does not have a unique tracking mechanism assigned to it, it is not ready to go live yet.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"7-day-window-kills-campaigns\">7. A 7-Day Window Kills Campaigns That Were Working<\/h2>\n      <p class=\"mp-p\">Podcast conversions do not arrive on a predictable schedule. A listener hears your ad on a Monday, considers it, searches your brand on Wednesday, and buys the following Sunday. If your attribution window closes at day 7, that Sunday purchase disappears from your data entirely. The campaign looks like it underdelivered. It did not. Your window closed too early.<\/p>\n      <p class=\"mp-p\">According to Podscribe&#8217;s Q4 2025 Performance Benchmark Report, host-read ads deliver a median conversion rate of 0.021% per impression measured across a 30-day window. That figure drops sharply if you close the window at day 7. Same campaign, same ads, same listeners, completely different numbers depending on when you stop counting.<\/p>\n      <p class=\"mp-p\">Conversions from podcast campaigns also arrive in waves. A cluster lands in the days immediately following an episode drop. Another arrives weeks later as new listeners discover older episodes in the back catalogue. Both are real. A short window only captures the first cluster and misses the second entirely.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">Set a 30 to 60 day attribution window in your analytics before the campaign launches. This is not optional. Do it before episode one airs, not after the results look confusing.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"frequency-or-reach-fixed-budget\">8. Frequency or Reach: Only One Matches Your Goal<\/h2>\n      <p class=\"mp-p\">Reach measures how many different people heard your ad. Frequency measures how many times the same person heard it. On a fixed budget, these two metrics pull in opposite directions. More shows means more reach and less frequency per listener. Fewer shows means deeper frequency and lower total reach. The decision between them is not a preference. It is determined by your campaign goal.<\/p>\n      <p class=\"mp-p\">A listener who hears your ad once on a show they trust might register a passing impression. A listener who hears your ad three times across consecutive episodes of the same show is in a different psychological state. Repetition builds familiarity. Familiarity builds trust. Trust shortens the path to a first purchase.<\/p>\n      <p class=\"mp-p\">Cumulus Media&#8217;s 2025 Audioscape study found that purchase rates increased meaningfully between the first and third listener exposure to a podcast ad, with the third exposure outperforming the first by a significant margin on direct response metrics. The fourth and fifth exposures showed diminishing returns.<\/p>\n      <h4 class=\"mp-h4\">When to weight frequency<\/h4>\n      <p class=\"mp-p\">Direct response campaigns with a specific conversion goal benefit from frequency. Three to five mid-roll placements on one well-matched show will typically outperform one placement each on five loosely matched shows at the same total budget.<\/p>\n      <h4 class=\"mp-h4\">When to weight reach<\/h4>\n      <p class=\"mp-p\">Brand awareness campaigns benefit from reach. If the goal is introducing your brand to as many relevant listeners as possible, spreading placements across multiple shows in the same category builds broader recognition. Niche shows with tight audience fit across several categories will outperform flagship shows with mixed audiences.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">Key Takeaway<\/span>\n        <p class=\"mp-p\">A direct response campaign structured like an awareness campaign, or vice versa, always underdelivers. The most common reason podcast budgets fail to generate usable data is a mismatch between the campaign goal and the media structure. Decide frequency or reach before you buy a single placement, not after the results come back flat.<\/p>\n      <\/div>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">Decide whether your primary goal is awareness or conversion before you structure your media plan. Then weight frequency or reach accordingly. Running a conversion campaign with an awareness structure produces weak results from either angle.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"measuring-awareness-no-link\">9. Measuring Awareness When There Is No Link to Click<\/h2>\n      <p class=\"mp-p\">Not every podcast campaign is built for a direct response conversion. Some campaigns run to build category awareness, shift brand perception, or introduce a product to an audience that does not yet know it exists. These goals require a completely different measurement approach.<\/p>\n      <p class=\"mp-p\">Brand lift is the measured increase in awareness, recall, favourability, or purchase intent among your target audience after exposure to your advertising. It cannot be tracked with a promo code. It requires a study design.<\/p>\n      <p class=\"mp-p\">The standard approach surveys a sample of listeners from your advertised shows and asks the same questions to a control group that did not hear the ads. The difference between the two groups is your lift score.<\/p>\n      <p class=\"mp-p\">Nielsen&#8217;s Podcast Ad Effectiveness research through Q2 2025 found that podcast campaigns generate on average a 10-point lift in brand awareness, an 8-point lift in information-seeking behaviour, and a 6-point lift in purchase intent. Unaided brand recall reached 70% among listeners exposed to podcast ads, compared to a 50% baseline among unexposed audiences.<\/p>\n      <div class=\"mp-stat-row\">\n        <div class=\"mp-stat-card\"><div class=\"mp-stat-figure\">+10 pts<\/div><div class=\"mp-stat-label\">Brand awareness lift<\/div><\/div>\n        <div class=\"mp-stat-card\"><div class=\"mp-stat-figure\">+8 pts<\/div><div class=\"mp-stat-label\">Information-seeking behaviour lift<\/div><\/div>\n        <div class=\"mp-stat-card\"><div class=\"mp-stat-figure\">+6 pts<\/div><div class=\"mp-stat-label\">Purchase intent lift<\/div><\/div>\n      <\/div>\n      <p class=\"mp-p\">Sounds Profitable&#8217;s June 2025 Trust and Attention report found podcast advertising delivers an 86% ad recall rate among the most active podcast users, the highest across any media platform tested, ahead of social, YouTube, and traditional broadcast.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">Pro Tip<\/span>\n        <p class=\"mp-p\">Brand lift is where podcast advertising genuinely separates from other digital channels. But it only tells a useful story if the measurement design is defined before the campaign launches. Retrofitting a lift study after the fact is not a substitute for building it in from the start.<\/p>\n      <\/div>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">If awareness is your primary goal, define brand lift as your lead KPI in the scorecard before signing. Align with a third-party measurement partner before the campaign launches. Applying conversion metrics to an awareness campaign will always produce misleading results.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"benchmarks-reference-metrics\">10. Podcast Advertising Benchmarks to Use as Filters<\/h2>\n      <p class=\"mp-p\">These numbers are reference points, not guarantees.

That result arrives without a visible link, a retargeted reminder, or a same-session click path.<\/p>\n      <h4 class=\"mp-h4\">Mid-roll CPM reference ranges<\/h4>\n      <p class=\"mp-p\">For current mid-roll CPM ranges broken down by show size, format, and genre, see the full <a href=\"\/blog\/podcast-advertising-cost-cpm-rates-by-genre-size\/\" rel=\"noopener\" target=\"_blank\">podcast advertising CPM rates guide<\/a><!-- verify slug before publishing -->.

If a show&#8217;s completion rate sits below 50% but the rate card is priced as if it delivers a 75% rate, that gap is the negotiation.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"data-at-30-and-60-days\">11. What Your Data Is Telling You at 30 and 60 Days<\/h2>\n      <p class=\"mp-p\">Week one data is mostly noise. Week two is still mostly noise. Day 30 gives you enough signal to assess trajectory. Day 60 gives you enough to make a defensible decision. Build both checkpoints into the campaign timeline before launch, not as an afterthought.<\/p>\n      <h4 class=\"mp-h4\">At 30 days, ask these questions<\/h4>\n      <p class=\"mp-p\">Has the promo code generated any redemptions? Even a small number confirms the tracking chain is working end-to-end. Has branded search volume in the show&#8217;s geographic market increased on or after air dates? Have post-purchase survey responses cited the show by name? These early signals tell you the campaign is landing, even if the conversion volume is still building.<\/p>\n      <h4 class=\"mp-h4\">At 60 days, make a decision<\/h4>\n      <p class=\"mp-p\">Calculate your fully loaded CPA including every conversion that arrived in weeks four through eight. Then compare it against the threshold you set in the scorecard before launch.<\/p>\n      <p class=\"mp-p\">If CPA is within 20% of your ceiling, renew. If it is within 40% above ceiling with no improving trend, run one more cycle with an adjusted creative brief. If it is more than 40% above ceiling after a full 60-day window with clean attribution, redirect the budget and document what you learned.<\/p>\n      <h4 class=\"mp-h4\">Three signals and what they mean<\/h4>\n      <p class=\"mp-p\"><strong>Rising signal:<\/strong> Increasing promo redemptions per episode, a declining CPA across the campaign run, and branded search upticks tied to air dates. This show is worth scaling before you discuss the data with anyone.<\/p>\n      <p class=\"mp-p\"><strong>Flat signal:<\/strong> Consistent redemptions but a CPA running above target. The show is working but the creative angle is not optimised. Before pulling budget, give the host a different hook, a stronger offer, or a more specific call-out to the listener&#8217;s situation. Run one adjusted cycle.<\/p>\n      <p class=\"mp-p\"><strong>Declining signal:<\/strong> Early episodes converting and later ones in the same run producing less. Repeated identical creative causes listener fatigue. The fix is a creative refresh, not a show exit.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">Write your renewal decision threshold in the scorecard before the campaign launches. If you have not defined the number in advance, you will rationalise whatever comes back.<\/p>\n      <\/div>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"lifetime-value-changes-roi\">12. Lifetime Value Changes Every ROI Calculation<\/h2>\n      <p class=\"mp-p\">There is one metric most advertisers never pull after a podcast campaign ends: the lifetime value of a podcast-attributed customer compared to customers from other acquisition channels.<\/p>\n      <p class=\"mp-p\">Podcast listeners who convert tend to arrive with higher intent. They heard a trusted voice describe a problem they recognised, sat with the idea for a few days, and chose to act. That path produces customers with stronger brand affinity and higher repeat purchase rates than customers who clicked a retargeted display ad mid-scroll.<\/p>\n      <p class=\"mp-p\">A 2025 report from Command Your Brand found that podcast-driven customers showed meaningfully higher early lifetime value compared to channel-average benchmarks across several direct-to-consumer categories.<\/p>\n      <p class=\"mp-p\">Here is why that changes the ROI calculation. A podcast customer generating $180 in 90-day LTV at a $60 CPA looks identical on a short-term scorecard to a paid social customer generating $80 in 90-day LTV at a $30 CPA. The CPA is higher for the podcast customer. The return on that spend is not even close. Evaluate both on the same CPA ceiling and you consistently undervalue the channel.<\/p>\n      <div class=\"mp-callout\">\n        <span class=\"mp-callout-label\">What to do<\/span>\n        <p class=\"mp-p\">After the 60-day attribution window closes, pull the 90-day LTV comparison between podcast-attributed customers and your channel average. Run that number before deciding whether the campaign&#8217;s CPA was too high.<\/p>\n      <\/div>\n      <p class=\"mp-p\">The brands seeing the best returns from podcast advertising right now are not spending the most. They are measuring most carefully: completion rate before download count, CPA ceiling before rate card, attribution setup before launch, and a 60-day window before any verdict. Set the framework before the first episode airs and the channel will show you exactly what it is worth.<\/p>\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"frequently-asked-questions\">13. Frequently Asked Questions<\/h2>\n\n      <p class=\"mp-faq-q\">What are podcast advertising metrics?<\/p>\n      <p class=\"mp-faq-a\">Podcast advertising metrics are the measurements that tell you whether a campaign is working, including episode completion rate, adjusted CPM, cost per acquisition, attribution coverage, and customer lifetime value. Download counts measure file requests rather than verified listens and should be treated as a starting ceiling, not a final audience count.<\/p>\n\n      <p class=\"mp-faq-q\">What is a good episode completion rate for podcast advertising?<\/p>\n      <p class=\"mp-faq-a\">Above 70% is strong for direct response campaigns, meaning your mid-roll ad reached a listener who committed fully to the episode. Between 50% and 65% is acceptable for awareness goals. Below 50% means a meaningful share of listeners left before your ad played, regardless of what the rate card shows.<\/p>\n\n      <p class=\"mp-faq-q\">How do you calculate adjusted CPM for podcast ads?<\/p>\n      <p class=\"mp-faq-a\">Adjusted CPM equals your published CPM divided by the show's completion rate, then multiplied by 100. A $30 CPM on a show with 70% completion actually costs $43 per 1,000 engaged listeners. This calculation reveals your true cost per listener, which the published rate card does not show.<\/p>\n\n      <p class=\"mp-faq-q\">How long should a podcast attribution window be?<\/p>\n      <p class=\"mp-faq-a\">Set a 30 to 60 day attribution window before your campaign launches. A 7 day window misses most podcast-driven conversions because listeners commonly hear an ad, consider it for several days, and convert in a later session from a different device. Closing the window early makes working campaigns appear to fail.<\/p>\n\n      <p class=\"mp-faq-q\">What attribution methods work best for podcast advertising?<\/p>\n      <p class=\"mp-faq-a\">Four methods together give the most complete picture: unique promo codes per show, vanity URLs, pixel-based attribution via platforms such as Podscribe or Claritas, and post-purchase surveys. Promo codes alone typically capture only 30 to 60% of true podcast-driven conversions.<\/p>\n\n    <\/section>\n\n    <section>\n      <h2 class=\"mp-h2\" id=\"references\">References<\/h2>\n      <hr class=\"mp-references-divider\">\n      <span class=\"mp-ref-item\">Podscribe.
