A website audit is a systematic check of your business website to find out what is broken, what is slow, and what is keeping people from reaching you. Simply put, what is a website audit comes down to a health check for your online presence, much like taking your car to a mechanic for an annual inspection before it breaks down on the motorway.
When you run a website review tool, it runs through dozens of hidden settings, links, and files in a matter of seconds. For a small business owner who pays the bills for the site but did not build it, knowing what these checks actually mean helps you decide what needs fixing and when to call a developer.
What is a website audit in plain English?
Your website is made up of code, design files, text, images, and server settings that all need to work together smoothly. Over time, things drift out of alignment. Pages get moved, plugins stop receiving updates, and links point to pages that no longer exist.
A structured website audit checklist takes the guesswork out of maintenance by looking at every corner of your site in an organised way. It covers how fast your pages load, whether search engines can read your pages properly, and whether your security certificates are up to date. Instead of waiting for a customer to email you to say a button is broken, an audit finds the problem first.
If you want a comprehensive look at the process from start to finish, you can read our guide on the full audit checklist to understand how different checks fit together.
What gets checked during a technical check-up?
When people ask what does a website audit check, they are usually thinking about the hidden mechanics behind the scenes rather than the words on the page. A thorough examination looks across several distinct categories:
- Speed and performance: How quickly your pages appear on a screen, and whether large images or heavy scripts are slowing things down.
- Search engine visibility: Whether Google and other search engines can crawl your pages and understand what your business actually does.
- Mobile usability: How the site behaves on smaller screens like smartphones and tablets, where a large share of your customers will view it.
- Security and certificates: Whether your site uses a secure connection and whether software updates are current.
- Broken links and errors: Finding pages that return error messages instead of showing your products or services.
Some of these items can be checked with automated software, while others require human eyes. For a deeper look at the performance side specifically, our guide on what Google measures breaks down the metrics that matter most.
Can you trust automated audit tools?
Automated software is brilliant at repetitive, large-scale checks. It can scan hundreds of pages in seconds, test every link to see if it works, and measure how fast your files download from the server. You should definitely use automated tools to catch quick technical errors.
However, automated tools have strict limits. They process data and run algorithms, but they have no understanding of human psychology, your brand, or your business goals. A machine can tell you that a page loads quickly, but it cannot tell you if your headline makes sense to a tired parent looking for your services at midnight.
The table below compares what automated software can do against what requires human judgement:
| Check type | Automated tools | Human review |
|---|---|---|
| Broken links | Instant and accurate | Unnecessary |
| Page loading speed | Measured in milliseconds | Needs real-device testing |
| Writing clarity | Cannot judge | Easy to spot confusing text |
| Design appeal | Cannot judge | Depends on your target audience |
| Legal compliance | Basic checks only | Requires careful reading |
What a machine can never tell you about your website
Software cannot tell you if your website is actually doing its job as a salesperson for your business. A completely error-free website can still fail to bring in enquiries if the message is confusing.
An automated tool will never know:
- Whether your main headline clearly explains what you sell within three seconds of a visitor arriving.
- If your contact form is so long and complicated that people give up halfway through filling it in.
- Whether your pricing and services match what your actual customers are looking for.
- If the overall design looks dated or untrustworthy to a first-time visitor.
This is why tools are best used as a starting point. They handle the tedious technical counting, leaving you or your team to look at the bigger picture.
How often should you run a website audit?
The question of how often should you audit your website depends on how frequently your business changes its content. A static brochure site needs less attention than an active e-commerce store with daily product additions.
As a general rule for small businesses, follow this schedule:
- Every month: Run a quick automated check for broken links, missing images, and basic security warnings. This catches accidental slips quickly.
- Every six months: Do a deeper dive into your search performance, mobile layout, and loading speeds to see if updates have slowed things down.
- Once a year: Conduct a full review of all content, contact forms, navigation menus, and design elements to ensure everything still aligns with your business goals.
If you launch a major redesign, change your domain name, or migrate your site to a new platform, run a comprehensive check immediately afterwards to confirm nothing broke during the move.
What to check first and how to start
If you look at every single metric on a professional technical report at once, it is easy to feel overwhelmed. Start with the basics that affect your customers directly: check that your contact form actually sends messages to your inbox, test the site on your own smartphone, and make sure your business phone number and address are correct.
