Hey everyone, I run a tech review channel with about 40k subs, and for the past two weeks I've seen a steady decline in my click-through rate (CTR) from 6.5% down to 4.2%. I recently switched to a more minimal thumbnail style (cleaner text, bigger product shots, less clutter) because I thought it would look more professional, but it seems to be hurting performance. My impressions are actually up slightly, but fewer people are clicking.
I've attached a side-by-side comparison of my old vs. new thumbnails. The old ones had bright colors, arrows, and a lot of text. The new ones are more like what big tech channels use – simple, high-res, with a bold word or two. I'm wondering if this is just a temporary dip as the algorithm recalibrates, or if I should revert back to my old style. Has anyone else experienced this after a redesign? Any advice on how to A/B test thumbnails effectively without confusing the audience?
