The Ultimate Technical SEO Checklist for 2025: A Guide for Australian Businesses

tipsseo
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.

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.

4. Site Speed and Performance

Speed is critical for user experience and rankings. You can test yours with PageSpeed Insights.

  • Compress images: Use formats like WebP and tools like TinyPNG.
  • Minify code: Tools like Minify Code or build processes via webpack or Gulp can help.
  • Use a CDN: Services like Cloudflare distribute your content worldwide.
  • Leverage browser caching: This stores files on the user’s device for faster repeat visits.
  • Check your Lighthouse score. Google Lighthouse is a performance benchmark of a website which impacts your search results. You can check your website Lighthouse score in the Revised dashboard.

5. Secure Your Website with HTTPS

Security matters. If your site isn’t using HTTPS, Google may flag it as insecure.

6. Structured Data and Schema Markup

Structured data helps search engines understand your content. It also powers features like rich snippets.

  • Use Schema.org types relevant to your business: Product, Review, Event, etc.
  • Validate markup with Google’s Rich Results Test.
  • The Revised dashboard can check and verify your structured data and schema map.

7. Canonicalisation

Duplicate content confuses crawlers and dilutes rankings.

  • Canonical tags: Use <link rel="canonical"> to point search engines to your preferred version.
  • Be consistent: Always link to the same version (with or without trailing slashes, www vs non-www).

8. Fix Broken Links and Redirects

Broken links hurt SEO and UX. Run a weekly check with tools like Screaming Frog.

  • Replace or remove broken outbound links.
  • Implement 301 redirects instead of letting pages 404.

Use Redirect Checker to test redirect chains.

9. Optimise for Core Web Vitals

Google’s Core Web Vitals are page experience metrics that directly impact rankings:

  • LCP (Largest Contentful Paint): Keep under 2.5 seconds.
  • FID (First Input Delay): Under 100 ms is best.
  • CLS (Cumulative Layout Shift): Aim for under 0.1.

The Revised dashboard will show you your core web vitals for your website.

10. Implement Hreflang for Multilingual Sites

If you serve multiple languages or regions, use hreflang attributes to prevent duplication.

  • Google’s guide to hreflang implementation is the best starting point.
  • Keep language targeting accurate and consistent across your sitemap and HTML.

11. Manage Crawl Budget

Google doesn’t crawl every page equally. Use these strategies to optimise what gets crawled:

  • Use noindex or robots.txt to block junk pages.
  • Avoid unnecessary parameter URLs.
  • Prioritise internal linking to key pages.

12. Regularly Monitor and Audit Your Site

Technical SEO is not “set and forget.”

Build these checks into your monthly workflow to stay ahead of issues. The Revised platform will constantly monitor your search performance and audit your site - alerting you to any issues.

13. Build Relevant and Contextual Backlinks

Relevant and contextual backlinks to your website and content are more relevant than ever.

  • Exchange links with business partners with your website and theirs
  • Get featured in local media and social media with links to your site
  • Ensure that the content around any links to your site is relevant to your website
  • Don't fall for cheap backlink provider services such as those on Fiverr or Upwork - these are all sourced from spam

Revised is a backlink platform. We use our large database of websites and backlinks along with AI to provide contextually relevant and powerful backlinks to your website.

Bonus: Technical SEO for AI-Driven Search

With the rise of AI-generated summaries like Google AI Overviews and chatbots like ChatGPT, technical SEO now plays a role in how AI perceives your site.

  • Ensure your content is well-structured with headings and summaries.
  • Use schema to make your content easier for AI to extract and represent.
  • Publish trustworthy content backed by expertise and verifiable sources.

Google’s AI and SGE tend to favour high-authority, clearly marked-up content.
