Why Your Website Is Slow (And the Fixes That Matter)

The short answer

Websites are slow for four main reasons, in order of impact: oversized images (the top culprit — compress to WebP, lazy-load below the fold), too much JavaScript (frameworks, trackers and plugins that block rendering), web fonts loading badly (use font-display: swap and load at most two families), and slow hosting (static files on a CDN beat a cheap shared server). Measure with PageSpeed Insights, fix images first — that alone transforms most sites.

Speed problems feel mysterious but rarely are. Run your site through PageSpeed Insights and the report will almost always point at the same four suspects. Fix them in order of impact, not in order of how interesting they sound.

The four causes, ranked

Images: a single 4MB hero photo outweighs your entire codebase — export at display size, convert to WebP, target under 300KB, lazy-load everything below the first screen
JavaScript: every plugin, tracker and framework runs before the page feels usable; delete what you don't use before optimising what you do
Fonts: self-host at most two families with font-display: swap so text renders immediately
Hosting: static files served from a CDN (Netlify, Cloudflare Pages — free) beat overloaded shared hosting, especially for visitors on Indian mobile networks

What numbers should you aim for?

Two metrics cover most of it: Largest Contentful Paint under 2.5 seconds (how fast the main content appears) and Cumulative Layout Shift under 0.1 (nothing jumps around while loading). Test on 'Mobile' in PageSpeed Insights, not desktop — that is where your traffic and your problems are.

It is far easier to stay fast than to get fast — retrofitting speed onto a plugin-heavy site is archaeology. A single-file site with no build step and no render-blocking bloat starts near the ceiling: the Volt drop template runs full GSAP animations while staying lean because there is simply nothing else to load. The same is true across the Interactive Template Bundle — one HTML file, your compressed images, a CDN, done.
