A technical SEO audit is a health check for your website. It is all about finding hidden problems that stop search engines like Google from showing your site to people. Think of it as checking the foundations of a house. If they are not solid, nothing you build on top will be safe.

Why Technical SEO Audits Are Not as Scary as They Sound

Let’s be honest, the words 'technical SEO audit' can sound scary. They bring to mind code, servers and other complex things. But it does not have to be that way. It is just about making sure your website is easy for search engines to find, crawl and understand. Without that, even the best content can get lost.

I have seen this happen many times. We worked with a national retailer who had a simple indexing error. It was blocking Google from seeing their most important product pages. It was a quick fix, but the impact was huge. Once we sorted it, their organic traffic went up by over 40% in just two months. This is why a regular check-up is so important.

The Foundation of Your Online Success

Imagine building a beautiful house on a weak foundation. It is not going to end well, is it? Your website is no different. A technical SEO audit makes sure your digital foundation is solid. This leads to some serious benefits:

• Improved Rankings: When Google can easily crawl your site, your pages are more likely to climb the search results.

• Better User Experience: Things that frustrate search engines, like slow pages or broken links, also annoy your visitors. Fixing them makes your site a much better place to be.

• Increased Traffic and Leads: A higher-ranking, faster site naturally brings in more visitors. For service-based businesses, this is a key part of our approach to getting leads online.

A technical SEO audit is not about becoming a coding expert. It is about finding the problems that stop search engines from rewarding you for your great content. It is the first real step towards getting the online visibility you deserve.

Getting Started with the Basics

You do not need to be a developer to understand the essentials. The goal is to find the problems so they can be passed to the right person to fix. If you want to learn more about the subject, this guide on understanding technical SEO is a great place to start.

Good technical SEO creates a smooth path for search engine bots and your human visitors. It makes sure there are no dead ends, confusing signs or slow pages on your site. By taking the time to run these checks, you are setting your business up for real, long-term growth online. This guide will show you exactly how to do it.

Your Essential Toolkit for a Technical SEO Audit

You would not try to build a house without a hammer and saw. You cannot do a proper technical SEO audit without the right software. Getting the right toolkit is the first step to finding out what is holding your website back.

We will go through the free and paid tools we use every day to get results for our clients at Milktree. I will not just list them. I will explain what each one does in simple terms. This way, you have everything you need before you check your website's health.

Starting With The Free Essentials

The best place to begin is with the tools Google gives you for free. They offer a direct look into how Google sees your website, so ignoring them would be a big mistake.

Google Search Console is essential. Think of it as your website's direct line to Google. It tells you which pages are indexed, shows errors that stop your pages from being seen and even shows you what people search for to find you. It is the most important tool for any website owner.

We always start our analysis here. The ‘Coverage’ report in Search Console is the very first thing we check. It gives us a quick, top-level view of any big indexing problems before we look deeper with other software.

This simple workflow shows how we start our technical SEO audits. We begin with Google's own data before moving to a more detailed check.

As you can see, the process flows from a high-level overview in Search Console to a deep, page-by-page crawl. Finally, it analyses the site's overall authority and health.

Moving To Paid Specialist Tools

While Google’s tools are essential, paid software gives you the detail needed for a full audit. Investing in the right tools can save you a lot of time and find issues you would otherwise miss.

Here are the main paid tools we rely on every day:

• Screaming Frog SEO Spider: This is our go-to for crawling websites. It acts like a search engine bot, visiting every page on your site and pulling all the data into one place. It is perfect for finding broken links, checking page titles and looking at your site structure.

• Ahrefs: While famous for its backlink analysis, Ahrefs has a brilliant ‘Site Audit’ tool. It crawls your site, gives it a health score and flags over 100 possible technical SEO issues. It is great for spotting problems like duplicate content or slow-loading pages.

Using a mix of tools is key. Google Search Console tells you what Google is seeing, while tools like Screaming Frog and Ahrefs help you understand why it is seeing it that way.

To give you a better idea, here is a quick comparison of the most popular tools we see in the industry.

Comparing Popular Technical SEO Audit Tools

This is not a full list, but these platforms are the foundation of almost every technical audit we do. Learning to use them will give you a powerful insight into your website's performance. With this toolkit, you are ready to get started.

Right, let's get our hands dirty. I am going to walk you through the exact technical SEO checklist we use. This is not just a generic list. It is a process we have improved across hundreds of client sites, focusing on what really makes a difference.

We will go through the most important checks. More importantly, I will explain why each one matters and how you can look into them yourself using the tools we have already covered.

Can Google Even Find and Read Your Pages?

First things first: can search engines actually get to your website? This is the foundation of technical SEO. If Googlebot cannot see your pages, they might as well not exist.

Your first stop should be your robots.txt file. It is a simple text file that tells search engine crawlers which parts of your site they can and cannot look at. You can usually find it by adding /robots.txt to the end of your domain name in the browser.

You are looking for any Disallow: rules that might be blocking important content by mistake. We once had a new client whose whole blog was disallowed after a site move. It was a single line of code, but it was costing them thousands in lost traffic. A classic, painful mistake.

After that, go to the 'Coverage' report inside Google Search Console. This is Google telling you which pages it has indexed and which it has not, and why. Look for errors like "Submitted URL blocked by robots.txt" or "Submitted URL has 'noindex' tag". These are big red flags that need sorting out straight away.

Hunting Down Broken Links and Pesky Errors

Broken links (those 404 errors) are a terrible experience for everyone. For a user, it is a dead end. For a search engine, it is a waste of its crawl budget.

The best way to find these is to run a crawl with a tool like Screaming Frog. It will give you a full list of every 404 error on your site. It will also show you which pages are linking to them. Fixing them is often just a case of updating the link or putting a 301 redirect in place.

Do not just focus on internal links. It is good practice to check for broken outbound links too. While they are not as damaging to your SEO, they still reflect badly on your site and create a frustrating journey for users.

Is Your Website Moving at a Snail's Pace?

It is no secret that page speed is a Google ranking factor. A slow site does not just annoy potential customers, it actively pushes you down the search results.

Your main tool here is Google's own PageSpeed Insights. It gives you a clear performance score for both mobile and desktop, along with a list of things to improve.

The usual problems we find time and again are:

• Massive image files: Large images that are not compressed are one of the biggest and easiest speed problems to fix.

• Bloated code: Clunky CSS and JavaScript files add extra weight and slow down your site.

• Slow server response times: Sometimes, the problem is just down to cheap or badly set-up web hosting.

Honestly, one of the biggest wins you can get from a technical audit comes from using proven strategies for image optimization that boost site speed and SEO rankings. Getting this right can give you a massive, almost instant performance boost.

Checking Your Site Structure and URLs

A logical site structure is a win-win. It helps users find their way around your site and helps search engines understand the relationship between your pages. This includes your URLs, which should be clean, readable and descriptive.

For example, a URL like yoursite.co.uk/services/garden-design is much better than yoursite.co.uk/page-id=123.

As part of your audit, you will want to check for a few key things:

• Duplicate content: This happens when the same or very similar content is on multiple URLs. It confuses search engines about which page to rank. The fix is usually to use a canonical tag to point Google to the one true version.

• XML Sitemaps: Think of this as a road map for search engines. You need to make sure it is up-to-date, includes all your important pages and is free of any junk you do not want indexed.

• Internal linking: Your pages should be linked together in a sensible way. Good internal linking helps spread authority through your site and guides both users and crawlers from one relevant page to another.

The global SEO market is expected to hit £84.2 billion by 2030. This kind of foundational work is more important than ever. For UK businesses, a solid technical audit is the cornerstone of any serious growth strategy. It clears away the hidden issues that hold you back. This checklist gives you the foundation you need to make sure your website is ready to compete.

Auditing Your Website for Mobile Users

It is no secret that most people now use their phones, not their desktops, to browse the web. This simple shift has completely changed how we need to build and look after websites. If your site is a pain to use on a small screen, you are not just frustrating visitors. You are telling Google you do not deserve to rank well.

This part of your technical SEO audit is all about seeing your site through the eyes of a mobile user. We will look at what ‘mobile-first indexing’ really means for your website. We will also walk through how to check for common problems that many sites have. Getting this right can make a huge difference.

What Is Mobile-First Indexing?

A few years ago, Google made a big change to how it works. It announced it would now prioritise the mobile version of a website when deciding how to rank it. This is mobile-first indexing.

Put simply, Google now crawls your site as if it were a mobile phone user. If your mobile site is slow, hard to read or missing key content that is on your desktop version, then that is the version Google uses for its ranking decision. Your beautiful desktop site is now secondary.

This is why a sharp focus on mobile performance is essential in any technical audit. Reports show that 64% of all internet traffic in the UK will be mobile. If you are not optimised for smaller screens, you are already falling behind.

Using Google's Tools to Find Problems

Thankfully, Google provides some excellent free tools to see your site the way its crawlers do. The first place to look should be Google's own Mobile-Friendly Test. Just enter your website’s address and it will give you a simple pass or fail.

But a simple pass is not enough. We need to dig deeper. Inside Google Search Console, you will find a report called 'Mobile Usability'. Think of this as your to-do list for mobile fixes.

It will flag specific issues that create a poor user experience on a phone, such as:

• Text too small to read: Forcing users to pinch and zoom is a classic sign of a non-mobile-friendly site.

• Clickable elements too close together: When buttons and links are crammed together, people will tap the wrong thing.

• Content wider than screen: This creates that awful horizontal scrollbar, making your site feel broken.

A quick pro-tip: Do not just rely on automated tools. Grab your own phone and actually try to use your website. Try to fill out a contact form, find your phone number or buy a product. You will often spot real-world frustrations that the tools miss.

A Real-World Example of Mobile Success

Let me tell you about a local service business we started working with. Their website looked great on a big monitor but was a complete disaster on a phone. Unsurprisingly, their enquiry numbers were flat.

Our initial technical audit immediately found major mobile usability problems. The navigation was broken, the phone number was not a 'click-to-call' link and the contact form was nearly impossible to fill out on a small screen.

We worked with their developers to create a new, responsive version of the site. We focused on making the mobile experience as smooth as possible. The results were almost immediate. Within three months of the new site going live, their organic traffic jumped by 75% and online enquiries more than doubled.

This is a perfect example of how fixing technical mobile issues directly drives business growth. It is a core part of our approach to local SEO for service businesses. Remember, your mobile site is not just a mini-version of your main website. In Google’s eyes, it is your main website.

How to Report Your Audit Findings Effectively

You have crawled the website, looked through the data and found all the technical problems. That is a massive win, but your job is only half-done. Finding the problems is one thing. Explaining them in a way that gets them fixed is a whole different ball game.

Your audit report is the bridge between your findings and real action. I have seen many brilliant audits fail at this final stage. They end up as a hundred-page document full of jargon that nobody reads. A report that just gathers dust is useless.

My approach has always been to keep things simple, focused and actionable. The goal is to show the value of your work and make it easy for clients or developers to understand what needs doing and why it matters.

Prioritise Your Findings Ruthlessly

Let's be honest: not all technical issues are equal. A single indexing error that is blocking your most profitable service page is an emergency. A few missing image alt tags? Not so much. Your first job is to cut through the noise and sort your findings into a clear order of importance.

I have always found a simple traffic light system works well. It puts issues into categories based on two simple things: impact and effort.

• High Impact / Low Effort (Red - Urgent): These are your quick wins. Think of a robots.txt file accidentally blocking your entire site. These issues cause big problems but are often simple to fix. They go straight to the top of the list.

• High Impact / High Effort (Amber - Important): This is where you might find something like a full site speed overhaul. These fixes will make a huge difference but need more planning and time. They need to be scheduled and budgeted for.

• Low Impact / Low Effort (Green - Good to have): This category is for general housekeeping tasks, like fixing a few broken internal links. They are worth doing, but they are not emergencies.

This simple method turns a long, scary list into a clear action plan. It helps everyone see where to focus first to get the biggest results.

Structure Your Report for Clarity

A good report tells a story. It needs to start with the big picture and then go into the details. It must always tie a technical problem back to a real business result. A report that just lists errors without any context will be ignored.

Here is a simple structure that I have found works really well:

1. The Executive Summary: Start with a single paragraph explaining the website's overall health. Is it in good shape or does it need urgent care? Mention the one or two most critical issues you found straight away.

2. The Priority Action Plan: This is your prioritised to-do list. I find a simple table is the best way to present this information clearly.

3. Detailed Findings: For each major issue, have a small section to explain it in plain English. No jargon, just a clear breakdown of the problem.

Your report should be all about solutions, not just problems. For every issue you highlight, you must provide a clear recommendation on how to fix it. This shows you have thought the process through and makes life easier for the person who has to make the changes.

Turning Data Into a Clear Action Plan

Let’s look at a simple template for presenting each issue. This format gets straight to the point. It explains the problem, why it is bad for business and exactly what to do about it.

This clear format cuts out the technical waffle. It connects every issue directly back to what the business cares about: traffic, sales and user experience. It turns your technical SEO audit from a list of problems into a strategic document that drives real change.

The success of your audit depends on how well you communicate your findings. For more on this, check out our guide on how to measure marketing campaign success, as clear reporting is a vital part of that process too.

Common Questions About Technical SEO Audits

Once you have gone through the whole process, from the initial checks to the final report, a few questions always seem to come up. We hear these all the time from clients, so let's run through the most common ones.

How Often Should I Run an Audit?

This really depends on your website. For a huge, busy ecommerce site that is always adding new products, a full technical audit every six months is a good idea. I would also run smaller, automated checks every month to catch any new issues before they get worse.

On the other hand, if you are running a smaller site that does not change much, a deep dive once a year is probably enough. The key is to be consistent so you can track your site’s health and progress over time.

Can I Do a Technical SEO Audit Myself?

You certainly can. Following a guide like this one and using free tools like Google Search Console will let you do a solid basic audit on your own. This is a great way to find and fix many of the common problems we have covered.

But, if you are dealing with a really large website or you have hit problems you cannot seem to fix, calling in an agency can be a smart move. We have access to advanced tools. More importantly, we have seen these problems hundreds of times before and know how to spot subtle issues that are easy to miss.

The real value of an experienced partner is not just in finding problems, but in knowing which ones will actually make a commercial difference to your business and prioritising them effectively.

What Is the Single Most Important Thing to Check?

If I had to pick just one thing, it would be crawlability and indexability. Put simply, can Google actually find and read all of your important pages? This is the foundation of everything in SEO.

Think about it: if Google is blocked from seeing your pages, it does not matter how fast your site is or how good your content is. Those pages will never get a chance to rank. That is why checking for simple mistakes like a 'noindex' tag in the wrong place or a typo in your robots.txt file is so important.

Will a Technical Audit Guarantee a Number One Ranking?

In a word, no. A technical SEO audit alone will not get you to the top spot. It is better to think of it as building the perfect foundation for a house. A technically sound website is vital for good rankings, but it is just one piece of the puzzle.

You still need the other core parts of SEO: creating helpful content that people love and earning quality links from other reputable sites. A technical audit clears the path. It removes the technical problems holding you back. This gives all your hard work and great content the best possible chance to shine and connect with the right audience.
