How to Check Your Website Speed (And What the Numbers Mean)

"Your website is slow."

You've probably heard this before. But what does "slow" actually mean? And how slow is too slow?

Why Speed Matters (In Real Numbers)

• 53% of mobile users leave if a page takes longer than 3 seconds to load
• Every additional second of load time reduces conversions by ~7%
• Google uses page speed as a direct ranking factor for both mobile and desktop

For a local business getting 500 visitors per month, shaving 2 seconds off your load time could mean 5-10 more leads per month.

The 4 Metrics That Actually Matter

1. Largest Contentful Paint (LCP)

What it measures: How long until the biggest visible element finishes loading.

Good: Under 2.5 seconds | Needs work: 2.5 to 4 seconds | Poor: Over 4 seconds

2. First Contentful Paint (FCP)

What it measures: How long until the user sees anything on screen.

Good: Under 1.8 seconds | Needs work: 1.8 to 3 seconds | Poor: Over 3 seconds

3. Total Blocking Time (TBT)

What it measures: How long the page is unresponsive to user input while loading.

Good: Under 200ms | Needs work: 200 to 600ms | Poor: Over 600ms

4. Cumulative Layout Shift (CLS)

What it measures: How much the page content moves around while loading.

Good: Under 0.1 | Needs work: 0.1 to 0.25 | Poor: Over 0.25

The 5 Most Common Speed Killers

1. Uncompressed Images

The #1 culprit. A single unoptimized hero image can be 3-5MB. Compress images to WebP format and aim for under 200KB per image.

2. Too Many Scripts

Every plugin, widget, and analytics tracker adds JavaScript that blocks page rendering. If you're not actively using something, remove it.

3. No Browser Caching

Without caching, every visit downloads everything from scratch. Enable caching so returning visitors load your site almost instantly.

4. Cheap Shared Hosting

Budget hosting puts hundreds of sites on one server. Consider managed hosting or a CDN like Cloudflare (free tier available).

5. Render-Blocking CSS

CSS files that load before any content can appear. Inline your critical CSS and defer the rest.

What to Fix First

1. Compress images. Biggest single improvement, easiest to do
2. Remove unused scripts/plugins. Less code = faster load
3. Enable caching. One-time setup, permanent benefit
4. Upgrade hosting. If all else fails, better infrastructure helps

Run a speed check to see exactly where your site stands. Most sites can cut their load time in half with the first two items.

Your website speed is the foundation everything else is built on. If it's slow, nothing else matters.
