CASE STUDY - "SILVER ECHO"&#010;Electronic duo Silver Echo spent $2,000 across playlist pitching, TikTok ads, and Instagram reels. By tagging each channel with unique smart links + pixels, they learned:&#010;Channel - Cost - New Followers - Saves - Stream Revenue - ROI&#010;  • Playlist pitching - $800 - 420 - 1,100 - $310 - -61%&#010;  • TikTok Spark Ads - $700 - 1,300 - 2,600 - $710 - +1%&#010;  • IG Reels Boosts - $500 - 330 - 450 - $120 - -51%&#010;They killed playlist spend, doubled TikTok budget, and added look-alike retargeting. Month 2 cost $1,400, earned $1,950 (ROI = +39%) and added 3,400 followers.&#010;&#010;WHY THIS QUESTION MATTERS&#010;Without clear KPIs and attribution, artists waste money on vanity metrics (impressions, likes) that never convert to listeners or revenue. A disciplined ROI framework lets you prove what works, cut what doesn’t, and scale only profit-positive channels.&#010;&#010;DEFINE SUCCESS METRICS&#010;KPI - What it measures - Tool / source - Typical target&#010;  • Streams per $ - cost efficiency of listens - Spotify for Artists + ad spend sheet - >= 200 streams per $1&#010;  • Save to Stream % - depth of engagement - Spotify for Artists - >= 10%&#010;  • Followers gained - long-term audience growth - Spotify / IG / TikTok dashboards - +5% per release cycle&#010;  • Email/SMS signups - direct-to-fan ownership - Mailchimp, Linkfire forms - 3% to 7% click to signup&#010;  • ROI - (Revenue - Cost) / Cost - sheet or Airtable formula - positive by Month 2&#010;Choose one North Star metric (for example, Save to Stream %) and 3 to 4 supporting KPIs.&#010;&#010;INSTRUMENT EVERYTHING&#010;  • Smart links and UTMs: ToneDen, Linkfire, Hypeddit. Add utm_source for every channel.&#010;  • Pixels: TikTok, Meta, Google. Fire "ViewContent" on landing and "Stream" after 30 sec via EventBridge or Bulkr.&#010;  • ISRC-level tracking: Chartmetric and Spotify "Recorded Music By Release" export.&#010;  • Manual tags: for playlist pitching fees, add a "Playlist" line item in the expense sheet.&#010;&#010;BUILD A LIVE DASHBOARD&#010;  • Data warehouse: Google Sheets or Airtable synced with APIs (Spotify, TikTok Ads, Meta Ads, DistroKid).&#010;  • Key formulas:&#010;    • ROI = (Revenue - Spend) / Spend&#010;    • Cost per Follower = Spend / Followers&#010;    • Save Rate = Saves / Streams&#010;  • Visualization: Looker Studio or Sheets charts to highlight green (profit) vs red (loss) channels.&#010;&#010;IMPROVE THROUGH RAPID EXPERIMENTS&#010;Variable - Low cost test - Success signal - Next move&#010;  • Creative - 2 cover arts on TikTok split test - 50%+ CPM drop - switch all spend to winner&#010;  • Audience - broad vs look-alike 3% - +30% CTR - scale winner 2x daily budget&#010;  • Offer - pre-save vs direct stream - 25% higher save rate - adopt for next release&#010;  • Timing - Friday vs Monday pitch - +15% playlist add rate - standardize release day&#010;Run tests for 48 to 72 hours at $20 to $50 each, log results, and roll the winner into the main campaign.&#010;&#010;SCALE WHAT WORKS&#010;  • Reallocate budget: shift spend to top quartile channels, pause the rest.&#010;  • Automation: use Zapier to pull daily stats into the dashboard and send Slack alerts when ROI < -20%.&#010;  • Retargeting: serve merch or tour ads to high engagers (stream >= 30 sec + saved track).&#010;  • Partnerships: show your ROI data to curators/influencers for better rates or rev-share deals.&#010;  • Quarterly review: reset benchmarks, archive under-performers, set a new testing roadmap.&#010;&#010;COMMON PITFALLS&#010;  • Tracking gaps (no pixel or broken UTM) -> impossible attribution.&#010;  • Chasing vanity metrics (views, generic followers) instead of saves or email signups.&#010;  • Over-scaling too early -> pumping budget before a channel is ROI positive.&#010;  • Data silos -> Spotify stats in one file, ad spend in another; merge into one sheet.&#010;  • Ignoring margin -> playlist fees may bring streams but zero revenue; count profit, not volume.&#010;&#010;KEY TAKEAWAYS&#010;  • One dashboard = one truth. Merge spend, engagement, and revenue in the same place.&#010;  • Tag every click. UTMs + pixels turn chaos into clear attribution paths.&#010;  • Test small, judge fast. 48-hour micro tests uncover winners without draining budget.&#010;  • Scale only profit-positive channels. Red channels pause automatically, green ones earn more spend.&#010;  • Revisit quarterly. Markets shift, keep benchmarks and ROI targets dynamic.&#010;Master this cycle and your marketing stops being an expense, it becomes a self-funding flywheel that compounds with every release.
