I was wondering, is mobile optimization really that crucial for website success?

It's a must for good user experience and higher search engine rankings.

It depends on your audience. If most of your visitors are on desktop, mobile optimization might not seem like a priority.

Mobile optimization is definitely important for SEO. Google prioritizes mobile-first indexing, meaning a website that’s not mobile friendly could be hurting its chances of ranking well.

Mobile users expect seamless experiences, if your site isn't optimized. You risk frustrating visitors and losing them to competitors.
