Technical & Mobile SEO

Optimising Your Website for Speed, Mobile-First Indexing, and Crawlability

8/5/20253 min read

When it comes to ranking high on Google, great content and keywords are only part of the equation. If your website is slow, not mobile-friendly, or difficult for search engines to crawl, you’ll struggle to rank no matter how good your content is. This is where Technical SEO and Mobile SEO come in.

In this guide, we’ll explain the key aspects of technical SEO and mobile optimisation, including website speed, mobile-first indexing, site structure, and crawlability — all essential for Australian businesses aiming to improve their online visibility.

Why Technical SEO Matters

Technical SEO focuses on improving the backend elements of your website to help search engines understand, crawl, and index your site effectively. Without solid technical foundations, even the best on-page SEO won’t perform well.

If you’re a small business in Australia — whether you’re running an SEO consulting service in Toowoomba, an online shop in Brisbane, or a tradie website in South Burnett — technical SEO ensures your website loads fast, looks great on mobile, and is easy for Google to crawl.

Key Elements of Technical SEO for Small Businesses

1. Website Speed Optimisation – Faster Sites Rank Higher

Google has officially confirmed that page load speed is a ranking factor. A slow-loading site not only hurts your rankings but also increases bounce rates.

• Use Google PageSpeed Insights or GTmetrix to analyse your site speed.

• Optimise images (compress large files using TinyPNG or WebP format)

• Minify CSS, JavaScript, and HTML to reduce page size

• Leverage browser caching and enable lazy loading for images

Ideal load time: Under 3 seconds.

2. Mobile-First Indexing – Google Prioritises Mobile Experience

Since Google switched to mobile-first indexing, it evaluates your mobile site version first before the desktop version.

To ensure your site is mobile-optimised:

• Use a responsive design that adjusts to screen sizes

• Avoid using Flash or outdated elements that don’t work on mobile

• Ensure fonts are readable and buttons are easily clickable

• Check your site’s mobile usability in Google Search Console

If your mobile experience is poor, you’re losing rankings and potential customers.

3. Site Structure – Clear Navigation for Users and Search Engines

A well-structured website helps users find information quickly and makes it easier for search engines to crawl.

Best practices:

• Use a simple URL structure (e.g., www.yoursite.com/seo-services)

• Ensure your site hierarchy is logical with clear categories and subcategories

• Implement internal linking between related pages and blog posts

• Create and submit an XML sitemap to Google Search Console

Example: For an SEO agency in Brisbane, have pages like:

• /seo-services-brisbane

• /case-studies

• /contact-brisbane-office

4. Crawlability – Making Your Site Easy for Google to Understand

Google’s bots (crawlers) need to scan your website content to index it properly. To improve crawlability:

• Use robots.txt to guide search engine bots on which pages to crawl

• Avoid orphan pages (pages with no internal links pointing to them)

• Fix broken links (404 errors) regularly

• Ensure important content is no more than 3 clicks deep from the homepage

Regularly monitor crawl errors in Google Search Console and fix issues promptly.

Other Technical SEO Essentials

HTTPS Security: Ensure your website uses SSL (HTTPS). Google gives ranking preference to secure websites.

Canonical Tags: Prevent duplicate content issues by using canonical tags correctly.

Structured Data (Schema Markup): Implement schema to enhance how your content appears in search results (rich snippets like star ratings, FAQs, etc.)

Fix Redirect Chains: Avoid multiple redirects (301 -> 302 -> page), as they slow down load times.

Why Mobile SEO is Crucial for Australian Small Businesses

With over 60% of Australian users accessing websites on their smartphones, ignoring mobile SEO is no longer an option.

Key benefits of mobile optimisation:

• Better user experience = lower bounce rates

• Higher mobile rankings = more local traffic (think “near me” searches)

• Increases conversions through mobile-friendly CTAs and forms
