Technical SEO Audit Services

Is your website feeling a bit under the weather? Maybe it’s not showing up on Google like it used to, or visitors seem to leave almost as soon as they arrive. Often, the problem isn't your content, it's something hidden underneath.

That’s where a Technical SEO Audit Service comes in. Think of it as a full health check-up for your website. It finds the hidden problems that stop Google from properly seeing, understanding, and ranking your site.

In this simple guide, we’ll explain what a technical SEO audit is, why it’s so important, and how it can fix your website to bring in more visitors. We’ll even show you how to do some basic checks yourself!

ARC Codes are Experts in technical SEO. We help businesses across the UK, from London to Edinburgh, build strong, healthy websites that Google loves. If you have any questions after reading, just call us at +44 7903 458 022 for a friendly, no-obligation chat.

What is a Technical SEO Audit Service in Simple Terms?

Think of Your Website Like a Car

You can have the shiniest, most expensive car in the world. But if the engine has a problem, it’s not going anywhere. Your website is the same.

The content of the words and pictures is the body of the car. It looks great.

The technical SEO is the engine, the brakes, and the electrical systems that make everything work.

A technical SEO audit service is like a skilled mechanic. They pop the bonnet, run diagnostics, and find out exactly why the engine is spluttering. Then, they give you a clear list of what needs fixing to get your car or website running smoothly again.

Why This Health Check is So Important

You might be writing brilliant blog posts or adding amazing new products, but if Google’s bots can’t crawl your site properly, it’s like putting those things in a locked room. No one can find them!

A technical audit makes sure there are no locks on the doors. It clears the path for Google, making it easy for them to find all your fantastic content and show it to people who are searching for it.

The Main Problems a Technical SEO Audit Finds and Fixes

A professional audit looks at hundreds of things, but most problems fall into a few key areas.

1. Can Google Find Your Pages? Crawlability

Google uses a robot called a crawler to explore your website. If this robot gets lost or blocked, it can’t find your pages.

The Problem: Broken links, a faulty robots.txt file, or poor server responses can stop Google in its tracks.

The Fix: The audit finds these blockages and clears the path so Google can crawl freely.

2. Can Google Read Your Pages? Indexability

Just because Google can find a page doesn’t mean it’s allowed to remember it for search results. This remembering is called indexing.

The Problem: Accidental noindex tags, duplicate content, or messy URLs can tell Google to ignore your pages.

The Fix: The audit finds these confusing signals and ensures Google knows exactly which pages to save and show to users.

3. Is Your Website Slow?

Nobody likes a slow website especially Google. A delay of just a few seconds can make visitors leave and can lower your ranking.

The Problem: Huge images, clunky code, or a slow web host can drag your speed down.

The Fix: The audit identifies what’s causing the slowdown and provides a clear plan to speed things up.

4. Is Your Website Phone-Friendly? Mobile-Friendliness

Most web browsing now happens on phones. If your site is hard to use on a mobile, you’re frustrating most of your visitors.

The Problem: Text that’s too small to read, buttons that are too close together, or a layout that doesn’t adjust to a small screen.

The Fix: The audit tests your site on mobile devices and recommends changes to make the experience smooth for everyone.

5. Is Your Website Safe and Secure? HTTPS

Would you enter your details on a website that said Not Secure? Probably not. Google also prefers secure sites.

The Problem: Your site is using old HTTP instead of secure HTTPS.

The Fix: The audit will check your security and guide you on moving to a secure connection, which gives visitors more trust.

What Happens in a Professional Technical SEO Check-Up?

Wondering what you get when you hire a company like ARC Codes for a Technical SEO Audit Service? Here’s a peek behind the curtain.

Checking Your Website’s Health with Special Tools

We use advanced tools like Screaming Frog, Ahrefs, and SEMrush to crawl your website just like Google does. These tools give us a huge amount of data on every single page, from the homepage to the product descriptions deep in your site.

Looking at Your Links and Website Structure

A good website is like a well-organised library. Everything should be in a logical section with clear signs. We check:

   Internal Links: Are your pages connected to each other in a helpful way?

   Site Architecture: Is your site’s menu and structure logical and easy to navigate?

   URL Structure: Are your web addresses clean and descriptive instead of messy

Testing Your Website Speed and Performance

We don’t just guess if your site is slow. We use tools like Google PageSpeed Insights and GTmetrix to get a detailed speed report. This report tells us exactly what to optimise, from compressing images to fixing render-blocking code.

Reading Your Google Analytics and Search Console Reports

The data in your Google Analytics and Search Console accounts is a goldmine. We look for:

   Crawl Errors: Pages Google tried to read but couldn’t.

   Index Coverage Issues: Pages Google has chosen not to remember.

   User Behaviour: Are people leaving a specific page very quickly? That’s a sign something is wrong.

How to Do a Basic Technical SEO Check Yourself For Free!

While a professional audit is the best way to find every issue, you can spot some big problems yourself. Here’s a simple 3-step check-up.

Step 1: Use Google Search Console

This is Google free tool to see how it views your site.

1.  Sign up for Google Search Console and add your website.

2.  Go to the URL Inspection tool and type in your homepage URL.

3.  It will tell you if the page is Indexed or if there are problems. Check a few other important pages too!

Step 2: Test Your Speed with PageSpeed Insights

2.  Type in your website’s address.

3.  It will give you a score for both Mobile and Desktop and a list of things to improve. Start with the suggestions labelled Opportunities.

Step 3: Check if Your Website is Mobile-Friendly

1.  Use Google’s Mobile-Friendly Test tool.

2.  Enter your URL.

3.  It will quickly tell you if your page has a mobile-friendly design. If it doesn’t, it’s a major problem to fix.

When Do You Need a Professional SEO Expert?

The DIY checks are a great start, but sometimes you need a pro. Here’s when to call in a team like ARC Codes.

You’ve Made Changes But Nothing Happened

If you’ve tried to fix things but your traffic still isn’t growing, the problem might be more complex than it seems. An expert can find the hidden issues you’ve missed.

Your Website is Very Big or Complex

If you have an Ecommerce site with thousands of products or a large business website, a manual check isn’t enough. You need a deep, automated crawl and expert analysis to manage that level of complexity.

You Don’t Have the Time to Learn It All

SEO is a deep and ever changing field. If you’d rather focus on running Your Business than learning the ins and outs of canonical tags and structured data, hiring a technical SEO audit service is a smart investment that saves you time and stress.

Common Questions About Technical SEO Audit Services (FAQs)

How long does it take to see results after a technical SEO audit?

Answer: It depends on the issues found. Some fixes, like fixing crawl errors, can show results in a few weeks as Google re-crawls your site. Larger projects, like a full site speed overhaul, take longer to implement but have a much bigger long-term impact.

What’s the difference between a Technical SEO Audit and a normal SEO audit?

Answer: A general SEO audit looks at everything: content, keywords, and backlinks as well as technical stuff. A technical SEO audit service dives much deeper specifically into the health and performance of your website’s infrastructure the things we’ve discussed in this article.

How much does a professional technical SEO audit cost?

Answer: The cost can vary based on the size and complexity of your website. A basic audit for a small site might start from a few hundred pounds. A comprehensive audit for a large e-commerce site will be a larger investment. At ARC Codes, we provide transparent pricing tailored to your specific needs.
