How to Audit a Website: 21 SEO, Performance & Technical Checks

A website can have good traffic and still lose potential customers because of small problems on the homepage.

Before redesigning a website or spending more money on traffic, it is worth checking the basics first.

Here are 21 practical checks that can help you understand where a website may be losing enquiries.

1. Conversion

These checks look at whether a visitor understands the website and knows what to do next.

Clear headline

Does the main heading clearly explain what the business does?

Primary action button

Is there a clear button or link asking the visitor to take a specific action, such as booking, getting a quote, buying, or requesting a demo?

Way to enquire

Is there a contact form or booking link on the page itself?

Proof you're trusted

Does the page show testimonials, reviews, ratings, clients, case studies, or other trust signals?

Action visible near the top

Is the first call-to-action visible near the top of the homepage?

2. Contact & Trust

Even when a visitor is ready to contact a business, small obstacles can make that harder.

Tap-to-call

Is there a clickable phone number using a tel: link?

Email contact

Is there a direct email address using a mailto: link?

Chat or messaging

Does the website provide WhatsApp, Messenger, Telegram, or live chat?

Business location

Does the website provide an address, map link, opening hours, location information, or similar business-location details?

Credibility signals

Does the website have signals such as a privacy policy, terms, about page, live social links, current copyright year, or cookie notice?

3. Findability

These checks look at some of the basic information search engines need to understand a page.

Page title

Does the page have a useful title tag that describes the business instead of using something generic such as "Home" or "Untitled"?

Search result description

Does the page have a meta description between 50 and 160 characters?

Main heading

Does the page have exactly one H1 in its real content?

Secure connection

Does the final URL use HTTPS, and are page resources also loaded securely?

Mobile setup

Does the page have the correct viewport configuration for mobile devices?

Structured data

Does the page contain valid JSON-LD, including structured data that describes the business itself?

4. Speed & Health

These checks look at some basic technical signals that can affect how quickly a page becomes usable.

Server response time

How quickly does the server respond?

The audit measures time to first byte, including DNS and connection setup.

Page code size

How much HTML does the browser actually download?

The tool checks the compressed HTML size rather than the decompressed size.

Scripts delaying the page

Are there scripts in the page head without async or defer that can delay rendering?

Image descriptions

What percentage of images have an alt attribute?

Decorative images with an empty alt attribute are handled correctly.

Text compression

Is the server using compression such as gzip or Brotli for text responses?

Why check these 21 things?

You don't need to start with a complete website rebuild.

A first-pass audit can help you identify obvious issues with:

Conversion
Contact options
Trust signals
Basic SEO
Mobile setup
Technical performance

The important part is knowing what is actually wrong, rather than relying on a generic website score.

You can check your website for free

We built a free website audit tool at CorgenX that checks these 21 areas on your homepage.

It gives you:

A score out of 100
Every finding in plain English
The evidence behind each finding

The audit scans your homepage only. It reads the HTML rather than judging a screenshot, and checks that cannot be verified are marked as not checked instead of being treated as failures.

The speed and health section also uses page size and script counts as technical proxies. It does not claim to replace real Core Web Vitals or a full-site crawl.

What happens after the audit?

The audit gives you a starting point.

Once you know which areas need attention, you can investigate the underlying problem and decide what actually needs fixing.

Start with your homepage

A website audit doesn't have to be complicated.

Start with the page most first-time visitors see.

Check the headline, action, contact options, trust signals, basic SEO elements, mobile setup, and technical health.

Then fix the problems that matter most.
