Technical SEO Audit: The Essentials You Can’t Ignore

Websites don’t slow down overnight. It happens gradually with a plugin update or a redirect. Over time, those small changes start to affect how Google sees your site. A technical SEO audit is a health check to make sure search engines can still read and trust your pages.

Think of it as a routine service rather than a fix after things go wrong. Using a practical technical SEO checklist, we check crawl paths, site speed, and index issues, then clean up what slows Google down.

At Infinix360, we handle this through detailed SEO Website Audit in Melbourne reviews. It’s not about technical jargon; it’s about making sure your site runs smoothly, loads fast, and is easy for search engines to trust.

How to Do a Technical SEO Audit?

Start by opening your site the way a customer would. Click around and note what feels slow or broken. Then, use a simple crawling tool to see what Google might struggle with, like missing titles, redirect loops, or pages that don’t load properly. After that, review your sitemap and Search Console reports. A quick look at your technical SEO checklist will show what’s working and what’s pulling your SEO audit score down.

Website Structure and Crawlability

When a site starts feeling slow or messy, it’s often because search engines can’t move through it properly. The structure is what keeps everything in order. A quick review usually shows where pages are hidden, duplicated, or just hard to reach.

• Keep URLs short and meaningful. A few words that describe the page are enough.
• Make sure every page runs on HTTPS. It keeps the site safe and consistent.
• Fix broken links. They waste Google’s crawl time and confuse users.
• Check the robots.txt file. Sometimes it blocks pages that should be visible.
• Open your sitemap once in a while and see if it still reflects what’s on the site. If you’ve added or removed pages, fix it and send the new version to Search Console.
• Remove any page that’s not useful anymore. If it’s outdated or not meant to appear on Google, take it out instead of leaving it buried in the sitemap. It keeps the crawl clean and makes indexing easier.
• Keep the structure easy to follow. From the homepage, anyone should be able to reach the right section in two or three clicks. If a page is buried too deep, move it up.
• Breadcrumbs aren’t fancy SEO tricks; they just help people move around without thinking.
• When you add links inside the site, use them where they genuinely help a reader find related information. Don’t force them everywhere.
• If two pages overlap, pick the one that matters most and mark it as the main version so Google doesn’t split the ranking.
• Checking these small things regularly is enough to keep your structure healthy and your SEO audit score stable.

Indexing

Google can only rank pages it can see, so the goal here is to make sure nothing important is being missed.

• Start by checking Search Console. Look at how many pages Google has crawled lately and see if that number feels right for your site size.
• Do a quick search using site:yourdomain.com. It gives you a rough idea of what Google has indexed; if key pages are missing, note them down.
• If you’ve got thin or duplicate pages, remove them or tag them so Google skips them.
• Use noindex or nofollow only when a page really doesn’t need to appear, like admin or confirmation pages.
• Check your meta tags once in a while. A single wrong line of code can hide a whole section without you realising it.

On-Page Technical Setup

Search engines read your pages the same way a visitor does, i.e., from the title down. The goal is to make that first impression clear and easy to follow.

• Your page title is the first thing users see. Keep it simple and true to the content. When titles read naturally, both people and search engines understand them better.
• Write meta descriptions like short summaries. They should explain the page, not sell it.
• Every page needs one main H1 that matches what the page is about.
• Use H2 and H3 headings to divide sections instead of bold text as it helps both readers and Google follow the structure.
• Check your site for repeated titles or tags. Duplicate elements make Google guess which version to show.
• Add alt text to every image. Just describe what’s in it.
• If the page includes reviews, events, or products, add schema so Google understands it better.
• Add Open Graph tags. It keeps shared links looking clean when people post them online.

Speed and Performance

A slow site loses both visitors and rankings. Page speed is one of the easiest things to measure and one of the hardest to ignore.

• Start with Google PageSpeed Insights. It gives you a fair idea of where the site lags and what needs attention first.
• Optimise your images so they load faster but still look sharp. Simple compression tools are often enough.
• Minify your CSS, HTML, and JavaScript to cut file size and remove clutter.
• Use a Content Delivery Network (CDN) to help pages load quicker for visitors across different locations.
• Turn on browser caching so returning visitors don’t reload the entire site each time.
• Go through your plugins and scripts; remove anything you no longer use.
• Enable lazy loading for images and videos so they appear only when someone scrolls to them.
• Check your server response time; if it’s slow, speak with your host or consider switching providers.

Fast pages leave a good impression and help improve your overall SEO audit score without any guesswork.

Speed and Performance

Nobody waits for a slow website anymore. If your pages take too long to open, both people and Google move on. When we go through a technical SEO checklist, fixing speed issues usually gives the quickest improvement in visibility.

• Test how fast your site loads using PageSpeed Insights and note what drags it down. A better SEO audit score often starts right there.
• Compress images properly, as they don’t need to be heavy to look good.
• Go through your backend once in a while and remove bits of code or plugins that have piled up over time. They quietly slow things down, even if they look harmless.
• It also helps to keep caching switched on and invest in hosting that can handle steady traffic. It’s one of those upgrades that pays off daily.
• A Content Delivery Network (CDN) also helps by reducing the distance between your site and your users.

Understanding how to do a technical SEO audit is mostly about noticing what slows the experience and fixing it before it affects traffic. Fast sites simply perform better on Google and with real people.

Security

A secure website builds trust with both visitors and Google. Keep these steps part of your regular technical SEO checklist to maintain a strong SEO audit score.

• Install an SSL certificate and make sure the site runs completely on HTTPS.
• Scan for any old HTTP links or images that still use insecure paths.
• Keep your website tools and plugins current. Old versions are easier targets for hackers.
• Use a firewall and run a quick malware scan once in a while to catch small issues early.
• Add a few security headers so browsers know how to handle your pages safely.

Advanced SEO Checks

When a site grows, it needs a bit more care behind the scenes.

• If you target a few countries or languages, set up hreflang tags so Google knows who each page is for.
• Check your blog and product pages. Ensure page numbers and links flow properly.
• Run your schema through Google’s tool once in a while to confirm it’s still valid.
• Cut down redirect loops, and add links to pages that feel a bit isolated.
• Look at how often Google visits your site. If it’s wasting time on low-value pages, trim them out.
• Have a quick look at your server logs now and then; they reveal how crawlers actually move through your pages.

It’s not complicated work, but doing it regularly keeps your SEO setup clean and stable.
