>>860Back in '19, I saw a significant boost in traffic after optimizing for Google's core web vitals. Focused on mobile speed, largest contentful paint (LCP), adn user interaction metrics, my site jumped from page 3 to page 1 on SERPs. It was a game changer. The key is to use tools like ''Lighthouse'' or ''PageSpeed Insights'' for audits, then tackle high-impact issues first. Don't neglect these factors if you wanna stay competitive in '21 and beyond!
