Ghost / Outline Buttons Lose to Filled Buttons — Consistently
[company] Tests confirm ghost buttons consistently underperform: Test #199 on Freshegg.co.uk (-20% progression), Test #243 on [company].org (-1.1% progression with red ghost vs red filled). Both show that reducing button visual weight decreases click rates. This is one of the most replicated anti-patterns in CRO.
Hypothesis
Ghost buttons (outline with transparent fill) test the principle that minimal design improves conversion — they don't.
