How to Speed Up Your Website (Step-by-Step)
How to speed up your website — the fixes that have the biggest impact on page load time, Core Web Vitals, and Google rankings for small business sites.

Short answer
The fastest wins for most small business websites are: compress your images (WebP format, under 150KB), switch to faster hosting, and remove unnecessary third-party scripts. These three changes typically cut load time in half.
Step 1: Compress your images
Images are the single biggest cause of slow websites. Every image on your site should be:
- Format: WebP (smaller than JPG/PNG at the same quality)
- Size: under 150KB for most images; under 50KB for thumbnails
- Dimensions: sized to how it appears on screen — don't upload a 3000px wide photo for a 600px column
Free tools:
- Squoosh — drag in an image, export as WebP in 30 seconds
- TinyPNG — batch compress JPGs and PNGs
- Cloudflare Images — automatically serves WebP to browsers that support it (Cloudflare free plan)
Step 2: Upgrade your hosting
Cheap shared hosting (under $5/month plans) puts thousands of sites on one server. When traffic spikes, your site slows. Switching to:
- Managed WordPress hosting (WP Engine, Kinsta) — significantly faster for WordPress sites
- Cloudflare Pages / Vercel — instant global CDN for static sites (free tier)
- A VPS (DigitalOcean, Vultr) — more control, dedicated resources
Even moving from slow shared hosting to a faster shared plan at a reputable host makes a measurable difference.
Step 3: Remove unnecessary scripts
Every third-party script (chat widget, social sharing buttons, analytics, fonts) adds load time. Audit what's running:
- Open Chrome DevTools → Network tab → reload the page
- Filter by "JS" — look for scripts from domains you don't recognise
- Remove anything you're not actively using
Google Fonts alone can add 300–500ms if loaded incorrectly. Self-host fonts or use display=swap in the font URL.
Step 4: Enable caching
Caching stores static versions of your pages so the server doesn't rebuild them for every visitor.
- Cloudflare (free) — enables browser and CDN caching with one DNS change. Free plan covers most small business sites
- WordPress: install WP Super Cache or W3 Total Cache (both free)
- Squarespace/Wix/Shopify: caching is handled automatically — nothing to do
Step 5: Minify CSS and JavaScript
Minification removes whitespace and comments from code files, reducing their size.
- WordPress: Autoptimize plugin (free) handles this automatically
- Custom sites: build tools (Vite, webpack) minify automatically in production mode
- Website builders (Wix, Squarespace, Shopify): done automatically — skip this step
Step 6: Use lazy loading for images
Lazy loading means images below the fold only load as the user scrolls to them — reducing initial page weight.
- HTML: add
loading="lazy"to<img>tags - WordPress: enabled by default since WordPress 5.5
- Website builders: enabled automatically on most platforms
How to measure improvement
Run PageSpeed Insights before and after each change. Key metrics to watch:
- LCP (Largest Contentful Paint) — under 2.5 seconds is good; under 4 seconds is acceptable
- CLS (Cumulative Layout Shift) — under 0.1 (layout stability)
- INP (Interaction to Next Paint) — under 200ms
Also watch your bounce rate in Google Analytics — slow pages push it up because visitors leave before the page finishes loading. A faster site is one of the simplest ways to bring it down.

Frequently asked questions
- How do I check my website speed?
- Use Google PageSpeed Insights (pagespeed.web.dev) — it's free, measures Core Web Vitals, and gives specific recommendations. Run your homepage and one or two inner pages. Aim for a score above 80 on mobile. GTmetrix is a good second check — it shows a waterfall chart of every resource loading.
- What slows down a website the most?
- The biggest culprits are uncompressed images (the most common issue on small business sites), slow hosting servers (cheap shared hosting), unminified JavaScript and CSS, and too many third-party scripts (chat widgets, analytics, social buttons). Fix images first — they account for the most speed improvement in most cases.
- Does website speed affect Google rankings?
- Yes — Core Web Vitals (LCP, CLS, INP) are a ranking factor. Google favours fast pages, particularly on mobile. More importantly, slow pages have higher bounce rates — users leave before the page loads. A 1-second improvement in load time can increase conversions by 2–7% on most small business sites.
