The mistake: sending uncompressed files

The mistake: sending uncompressed files

An easy-to-miss issue: your HTML, CSS, and JavaScript travel to visitors uncompressed. Text files squeeze down beautifully — often 70 percent smaller — but only if your server turns compression on. Skip it, and every visitor downloads bloated files, slowing LCP — Largest Contentful Paint.

Think of it like shipping a folded-flat box versus a fully inflated one. Same contents, fraction of the space.

How to fix it:
— In PageSpeed Insights, look for Enable text compression.
— On your server or host, switch on Gzip or, even better, Brotli compression.
— Most modern hosts have a single toggle for this.

Try this: run your page and search the report for text compression. If it's flagged, that's free speed waiting behind one setting. This one's easier than it sounds.
