If you want your website to appear high up on Google in Australia, you need more than just good words and lovely pictures. Google uses thousands of small clues, known as technical SEO, to determine which pages to show first. A lot is changing in how Google ranks pages, so it’s smart to keep your site sharp and up-to-date.
As Australia grew from a land known for kangaroos and Vegemite into a tech-savvy country, technical SEO also advanced and became more essential. Australian businesses are expected to spend $1.5 billion on SEO services in 2025, which is a 12% increase from 2024
This Technical SEO Checklist for 2025 will guide you, step by step, so you don’t miss anything important.
Why Does Technical SEO Matter for You?
Imagine building a fantastic shop in Sydney, but then putting up fences so nobody can walk in. That’s what happens if your website has technical SEO issues. If Google’s robots can’t find, understand, or safely display your site, it won’t matter how great your products are, nobody will see them.
Making your website easy for Google to access means more visitors, more customers, and less money wasted. Here is your simple, helpful Technical SEO Checklist for Australia.
1. Check Site Crawlability and Indexing
Before you consider a fancy design, ensure that Google can see and list every page you want to display.
How do you check this?
- Use Google Search Console. This free tool checks if your pages are being found and identifies any issues.
- Look at your robots.txt file. This small file instructs Google on which sites to exclude from visiting. Make sure it’s not blocking anything important.
- Your XML sitemap is like a map you give to Google. Update it when you add or remove pages.
Why does this matter?
If a page isn’t crawled or indexed, it won’t show up in search at all. For help, see the SEO Services Sydney page from iSonic Media.
2. Boost Site Speed and Core Web Vitals
Google wants your site to load fast on all devices. Slow sites can drop down in the results, especially for people in Australia who often use mobile data.
Core web vitals are three precise measurements:
- Largest Contentful Paint: How fast your main content loads (aim for under 2.5 seconds).
- First Input Delay: How quickly users can click and interact (under 100ms).
- Cumulative Layout Shift: How much stuff jumps around as the page loads (keep it below 0.1).
How do you fix slow sites?
- Shrink images using free tools.
- Use a simple layout.
- Don’t load videos automatically.
- Try Google PageSpeed Insights to see what’s slow.
Site speed is part of Google’s leading SEO ranking factors for 2025. Faster sites welcome more visitors and help your ranking.
3. Mobile-First Indexing
Most people in Australia use phones to browse the internet. Google continuously checks the mobile version of your website first. If your site doesn’t work well on a phone, you have a problem.
What to do:
- Open your site on your phone. Is it easy to use? Can you read the text without needing to zoom in?
- Use a responsive design so your site changes to fit any screen.
- Avoid pop-ups that cover the whole page.
- Check Google’s Mobile-Friendly Test tool.
4. Secure Your Site with HTTPS
Security is not just for online banks , Google cares if your site is safe for everyone who visits.
This means always using HTTPS (look for the little padlock in the browser bar).
If your site says “Not Secure,” visitors might leave.
How to check:
Type your website address into the browser. If it doesn’t have the padlock, contact your hosting company or web expert immediately.
5. Organise Your Site Structure
A good website layout is like a supermarket with clear signs. If visitors (and Google) can easily find what they want, they’ll stay longer.
How to fix the site structure:
- List your main topics as clear menu items (like Home, About, Services, Contact).
- Ensure that every important page can be accessed in three clicks or fewer from the home page.
- Use internal links. For example, on the iSonic Media blog, you’ll see links to the homepage and the About Us page. This helps visitors move around.
6. Use Clean URLs and Proper Meta Tags
Your web address (URL) should tell people, and Google, what the page is about.
- Use short, simple URLs: for example, /technical-seo-checklist
- Don’t use random letters and numbers.
- Add your keyword to the URL if possible.
Each page should have its title (the name displayed at the top of the browser or in search results) and a meta description (a brief explanation of the page’s content).
These are small details that help you show up higher when people search in Australia.
7. Improve Navigation
Clear and simple navigation helps both users and search engines. When a site is easy to get around, Google gives it extra points.
- Use a navigation bar at the top of each page.
- Create breadcrumb trails on your pages. These look like “Home > Services > SEO” and help users know where they are.
- Use simple words in dropdown menus and avoid excessive depth.
- Verify that links function correctly and don’t lead to 404 errors.
8. Fix Broken Links and Errors
Google does not like pages with broken links (called 404 errors) or pages that don’t load (server errors).
- Check your site for broken links using free tools like Google Search Console.
- Remove or update incorrect links.
- If you remove a page, redirect it to another relevant page.
9. Add Structured Data SEO (Schema Markup)
Structured data is a hidden language for search engines. It provides Google with details about your business, such as your address, phone number, and the services you offer.
- Adding schema can transform your listing into a “rich snippet” with additional features, such as star ratings or prices.
- For Australian businesses, add your correct local details.
10. Avoid Duplicate Content
If different pages on your site have nearly identical content, Google may become confused and struggle to determine which one to rank first. This can hurt your site.
Tips:
- Check for pages that repeat information.
- Use canonical tags to show Google which is the “main” version.
- Don’t publish the same page for every city in Australia with only the city name changed.
11. Use Internal Links (But Not Too Many)
Internal links aren’t just for search engines. They help visitors stay on your site and discover more about your business.
- Whenever you mention a topic you have a page about, link to it.
- For example, in this blog, there are links to the iSonic Media contact page for questions.
- Don’t turn every word into a link. Use links that help your readers move through your site.
12. Focus on Local SEO for Australia
If your business is located in Australia, ensure that Google knows your exact location.
- Show your city, state, and business hours.
- Add your business to Google My Business and keep info updated.
- Use local words where it makes sense (like “Sydney SEO” if you’re in Sydney).
13. Regular Technical SEO Audits
Don’t check your site just once and forget about it. The digital world in Australia is constantly evolving!
- Run a technical SEO audit every few months.
- Resolve issues promptly to prevent your site from dropping in rankings.
- Read more about website audits on the iSonic Media SEO Services Sydney page. They are one of the leading SEO experts in Sydney.
