Hey Gruzoviktor, ever notice how a single tweak in font spacing can turn a lukewarm ad into a sales juggernaut? I’ve seen the data on it—mind if we dive into it?

Sure thing—here’s the skinny: studies show that a 3‑5% increase in letter‑spacing on headline copy boosts click‑through rates by roughly 12% and reduces eye‑strain, so people actually read longer. On product pages, tighter kerning on body text can lift conversion by about 7% when paired with a high‑contrast call‑to‑action. The bottom line? Try a 3‑pixel kerning tweak in your next test; if the metrics don’t spike, drop it fast and move on.
