Design YouTube video thumbnails that earn the click — mobile-legible, one focal point, honest. Use when someone wants to design a YouTube thumbnail, improve CTR, brief a thumbnail, choose thumbnail text, or plan thumbnail A/B testing. Designs and briefs high-CTR thumbnails and writes the A/B test plan: a thumbnail is a promise, not a poster, designed as a unit with the title and legible on mobile. Uses the CLICK framework. Reads brand-profile + the video/title first. A HUMAN or an image/design tool (nano-banana/ideogram/Canva/designer) creates the final raster; the YouTube custom thumbnail is uploaded NATIVELY in Studio (WoopSocial has no thumbnail field) and Test & Compare is native; TikTok/IG-Reel covers use WoopSocial's cover field via those format skills. No clickbait, no unconsented real-person/deepfake faces, CTR never fabricated. Distinct from youtube-publishing-and-metadata (the metadata) and nano-banana/ideogram (which generate the raster this briefs).
