Why this matters for the Core Web Vitals, and where to start fixing it
What the LCP element is decides the playbook. An img can be prioritized, preloaded and right-sized. A CSS background image has a discovery problem first: the browser cannot see it until the CSS applies. Text means rendering waits on a font, not an image. Video means the poster frame is the candidate to optimize.
Text LCP is the underrated option. A headline renders as soon as its font is ready, no megabytes involved. A fast headline beats a slow hero, and a site gets to choose which one it leads with.
