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

Staying visible in search engines like Google and Bing takes more than well-written content and a nice website. Technical SEO helps your website get discovered, crawled, and understood by search engines.

If you're running a business in Australia and want to increase traffic and rankings, this checklist covers what you need to fix your site's technical foundation in 2025.

1. Website crawling and indexing

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.

Check your robots.txt file. Make sure it isn't blocking important content. Submit an XML Sitemap through Google Search Console and Bing Webmaster Tools.

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

Logical site structure

Organise your content like a clear hierarchy: Home > Category > Page. This improves navigation and crawl efficiency.

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 matters 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 that 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.

SSL Certificate. Use free options like Let's Encrypt.

Fix mixed content. Scan for insecure links using Why No Padlock?.

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.

INP (Interaction to Next Paint). Under 200ms is the target. This replaced FID in March 2024.

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."

Use Google Search Console to monitor errors, sitemaps, and performance. Track metrics in Google Analytics 4. Audit with tools like Sitebulb, Ahrefs Site Audit, or Semrush.

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 matter more than ever.

Exchange links with business partners. Get featured in local media and social media with links to your site. Make sure the content around any links to your site is relevant to your website. Don't fall for cheap backlink provider services like those on Fiverr or Upwork. These are 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 AI-generated summaries like Google AI Overviews and chatbots like ChatGPT, technical SEO affects how AI perceives your site.

Structure your content well 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 prefer high-authority, clearly marked-up content.
