Website performance is a crucial factor in SEO rankings, and one of the most powerful tools in your optimization arsenal is the preload tag. Let's dive into how you can use this nifty HTML element to give your site the speed boost it needs.
What Is the Preload Tag?
The preload tag is a resource hint that tells browsers to start loading specific resources earlier in the page lifecycle. It's like giving your browser a heads-up about important files it'll need soon. By using <link rel="preload">, you're essentially saying, "Hey browser, this resource is super important - grab it ASAP!"
