Search advertising on Google - pay per click on search results
Spotify, Pandora, and other audio streaming platforms
The auction, the creative, the budget floor — the three things you actually need to know before picking a platform.
Google Ads runs a real-time second-price auction on every search query. You pay per click, and your effective CPC is a function of your bid, Quality Score, and competitor bids — high-intent commercial keywords (finance, legal, insurance) can 5-10x the platform average because auction density is brutal.
Responsive Search Ads: up to 15 headlines (30 chars each), 4 descriptions (90 chars each). Google mixes them dynamically. Sitelinks, callouts, and structured snippets are effectively required to stay competitive.
Budget floor to reach statistical signal: roughly $50–100/day per campaign, or $1.5K–3K/month per keyword theme. Below that, learning phase never stabilizes.
Spotify, Pandora, iHeart, and podcast networks sell audio ads on CPM. Rates run $15–25 depending on demographic targeting depth. Podcast host-read ads bill differently (flat fee per episode + CPM top-up), but programmatic streaming audio is standard CPM.
15s or 30s audio, .mp3 or .wav, 128kbps+ recommended, with a companion display banner (300×250) for the app UI. Sound design matters more than script — this is background-attention media.
$2K–5K/month gets meaningful reach on Spotify's self-serve platform. Podcast-network buys typically start at $10K/month for host-read integration.
