Can Good Graphic Design Really Affect a Business’s Growth?

How much does graphic design actually move business results ? I get it, like good design makes a brand feel more professional, but I’m kinda wondering if anyone has really seen measurable changes, not just vibes. You know, stuff like sales , engagement, conversions or even customer trust. Say, if a company swaps a website banner, or updates the look of their social media, or changes packaging and ads, can that genuinely shift how people respond? Like more clicks, more sign-ups, better buying behavior? Or is graphic design mostly just about giving a business a cleaner, more credible surface, while growth comes mainly from other things like product quality, pricing, SEO, or outreach ? Have you personally changed something visually and then noticed a clear difference in outcomes, maybe in traffic, leads, or repeat customers ?
