The Ultimate Technical SEO Checklist for 2025: A Guide for Australian Businesses
Technical SEO is the backbone of your website’s performance in search engines. From site speed to mobile optimisation, this comprehensive checklist covers everything you need to ensure your site is search-engine friendly and AI-ready in 2025.
Staying visible in search engines like Google and Bing takes more than just well-written content and a nice website. Technical SEO is what ensures your website can be discovered, crawled, and properly understood by search engines.
If you’re running a business in Australia and want to increase your traffic and rankings, the checklist below gives you everything you need to tighten up your site’s technical foundation in 2025.
1. Website Crawling and Indexing
a. Ensure Proper Crawling
Search engines use bots (also called crawlers or spiders) to read your site. If your website can’t be crawled, it won’t appear in search.
- **Robots.txt file**: Make sure your file isn’t blocking important content.
- **XML Sitemap**: Submit one through Google Search Console and Bing Webmaster Tools.
b. Indexing Important Pages
Not every page needs to be indexed. Use the noindex meta tag on low-value pages like cart pages or internal search results.
Check indexing reports in Search Console and fix excluded pages where needed.
2. Site Architecture and URL Structure
a. Logical Site Structure
Organise your content like a clear hierarchy: Home > Category > Page. This improves navigation and crawl efficiency.
b. SEO-Friendly URLs
Use URLs that are short, descriptive and contain your target keywords:
- Good: www.example.com/solar-installation-wollongong
- Bad: www.example.com/page?id=5789&cat=20 Use 301 redirects for old URLs and avoid broken links.
3. Mobile Optimisation
Google now uses mobile-first indexing, which means your mobile site is the version that matters most.
- Responsive Design: Use flexible layouts with CSS media queries.
- No intrusive interstitials: Avoid pop-ups that block content on mobile.
- Test your mobile performance: Use Google’s Mobile-Friendly Test.
