5 Things Killing Your Website's Performance Right Now

Slow websites lose customers. That's not opinion — Google's own data shows that as page load time goes from 1 second to 3 seconds, the probability of a visitor bouncing increases by 32%. At 5 seconds, it's up 90%.

The frustrating part? Most performance issues on small business websites come from the same handful of culprits. Here are the top 5 we find on virtually every audit.

1. Massive, unoptimized images

This is the #1 performance killer, hands down. Someone uploads a 4,000-pixel-wide hero image straight from their phone, the website displays it at 1,200 pixels, and the visitor's browser is forced to download all 8MB of it before the page can render.

The fix:

• Resize images to the actual size they'll display
• Compress them (TinyPNG, ImageOptim, or Squoosh.app — all free)
• Use modern formats like WebP instead of JPG/PNG when possible
• Enable lazy loading so images below the fold load only when scrolled to

Just doing image optimization can cut load time by 40-60% on a typical small business site.

2. Render-blocking JavaScript and CSS

When a browser hits your page, it can't show anything to the visitor until it has finished loading and parsing certain CSS and JavaScript files. If those files are huge or loaded inefficiently, your visitor stares at a blank screen.

The fix: Defer non-critical JavaScript with async or defer attributes, inline critical CSS, and remove any plugins or scripts you don't actually need. (You'd be amazed how many sites are loading a chat widget, analytics tool, three font libraries, and a slider plugin they don't use anymore.)

3. Too many third-party scripts

Each script you add — Facebook Pixel, Google Tag Manager, that fancy popup tool, live chat — adds load time. Most small business sites end up with 8-15 third-party scripts, and each one is a request to a server somewhere else on the internet.

The fix: Audit your scripts quarterly. Ask: "Am I actually using the data this is giving me?" If not, remove it. If yes, make sure it's loading asynchronously so it doesn't block your page from rendering.

4. No browser caching or CDN

When someone visits your site, their browser downloads everything — CSS, JS, fonts, images. If you don't tell the browser to remember those files, it re-downloads them on every page load. And if your server is in one geographic location and your visitor is across the country, every file has to travel that distance.

The fix: Use a CDN (Cloudflare has a generous free plan), and configure your server to send caching headers for static assets. Most modern hosts handle this automatically — but "most" isn't "all," and if your host is the cheapest one you could find on Google, this is probably part of why your site is slow.

5. Cumulative Layout Shift (the jumpy page problem)

This one isn't strictly about speed — it's about perceived speed. Have you ever tried to click a button on a page, only for an ad or image to load and push the button somewhere else right as you tap? That's Cumulative Layout Shift (CLS), and Google now penalizes sites that do it.

The fix: Always specify width and height attributes on images and embeds, so the browser reserves the right amount of space before the content loads. Avoid inserting content above existing content unless triggered by a user action.

How do you know if your site has these problems?

You don't have to guess. Run your URL through our free website audit. The Performance category alone will tell you exactly which of these (and a dozen other) issues your site has, with severity rankings.

Performance fixes are usually the highest-ROI work you can do on a website. They're often quick, they don't require redesigning anything, and they directly translate to better conversion rates and higher search rankings.
