Your website is often the first impression your business makes, but if it’s slow, outdated, or full of hidden technical issues, you’re losing customers before they ever see what you offer. Learning how to do a website health check is one of the simplest ways to boost your visibility, user experience, and conversion potential.

A website health check gives you a snapshot of your site’s performance, speed, technical stability, and overall user experience. Think of it like a digital tune-up: fix the issues now so you don’t end up paying for them later.

And the truth? The numbers speak for themselves.

Why doing Website Health Check Matters

53% of mobile visitors leave if your site takes longer than 3 seconds to load (Google).
A delay in page load time of just 1 second can reduce conversions by up to 20% (Akamai).
When load time increases from 1 to 3 seconds, bounce rate probability increases by 32% (Google).
70% of consumers say page speed impacts their willingness to buy (Unbounce).

A slow or poorly performing site isn’t just inconvenient, it’s costing you traffic, trust, and money.

Step 1: Run a Speed & Performance Audit

Start with free online tools that scan your site in seconds:

These tools will show you:

Load times
Core Web Vitals
Mobile vs. desktop performance
Cumulative layout shift
Large images or scripts slowing you down

Your goal isn't a perfect score, it’s improvement. Even getting from an 80 to a 90 can dramatically increase performance.

Step 2: Check Mobile Responsiveness

More than 60% of all website traffic is mobile, and Google indexes mobile-first. If your site looks clunky, broken, or slow on a phone, your ranking and conversions take a hit.

Use Google’s Mobile-Friendly Test (if available) or simply test your site manually on multiple devices.

Step 3: Fix Broken Links & Errors

Broken links hurt SEO and frustrate visitors.Use tools like Broken Link Checker:

Look for:

404 errors
Redirect loops
Outdated pages
Missing images

Step 4: Review On-Page Elements

A healthy website also includes:

Clean headings (H1, H2, H3…)
Descriptive meta titles & descriptions
Correct alt text
Updated content
Keyword-optimized pages
Fast-loading images

This improves search engine visibility and helps visitors find what they need quickly.

Step 5: Review Hosting & Security

A slow server = a slow site.

Check:

Your hosting plan
SSL certificate
Security plugins or updates
Backup systems

Security is part of website health, a hacked site can tank your SEO overnight.
