Technical SEO Sydney
The foundation your rankings sit on
If Google can’t crawl your pages, render your JavaScript or load them fast, no amount of content or links will save your rankings. We audit, fix and verify the technical side of your site, and we implement the fixes ourselves instead of handing you a report. Senior specialists, since 2006.

The technical problems that suppress rankings
Broken links and duplicate titles are cosmetic. The issues that hold rankings back are architectural, and automated tools rarely flag them.
Content Googlebot can’t see
Single-page apps, React-rendered content and lazy-loaded sections can leave Google indexing something different from what users see. Without a rendered-DOM comparison, the gap goes unnoticed for months.
Crawl budget spent on the wrong URLs
Tracking parameters, faceted navigation and session URLs soak up Google’s crawl, while your money pages get visited weeks late.
Migrations that wipe out traffic
Domain moves, CMS changes, URL restructures and HTTPS migrations routinely destroy 30–60% of organic traffic without proper technical SEO planning.

What a crawler flags vs what we diagnose
Automated tools are a starting point. Ranking-level problems need someone to trace the cause.
| Topic | Automated tool report | Our technical audit |
|---|---|---|
| JavaScript | Automated tool report:Checks the raw HTML | Our technical audit:Compares what Googlebot receives with the rendered DOM |
| Crawl budget | Automated tool report:Lists the URLs it found | Our technical audit:Maps where Googlebot spends its time, from your server logs |
| Core Web Vitals | Automated tool report:A score for each metric | Our technical audit:The cause chain behind each failure, and the fix |
| What you get | Automated tool report:A spreadsheet of issues | Our technical audit:Fixes implemented, then verified in Search Console |
What our technical SEO covers
We don’t hand you a report and walk away. We implement the fixes, then check each one worked.
Find the real cause
- A full Screaming Frog crawl checked against Search Console for orphaned pages, crawl traps and broken internal links
- Log-file analysis that shows where Googlebot actually spends its time
- Core Web Vitals root-cause analysis: each LCP, INP and CLS failure traced to its exact cause and fixed in the code
- JavaScript rendering audits for React, Vue, Angular and Next.js, with server-side rendering or prerendering where Google misses content
Fix it at the source
- Crawl waste removed: parameter URLs and thin paginated pages, with redirect chains collapsed to single 301s
- Canonical strategy and a robots.txt and noindex audit, so Google indexes exactly what you want
- Schema from LocalBusiness and FAQPage to Product and BreadcrumbList, tested in the Rich Results Test
- AI search readiness: FAQPage schema, clean heading hierarchies and fast pages that AI retrieval systems can extract
- Migration risk assessment: a pre-migration redirect map, content parity checks and a post-launch crawl audit

How much does a technical SEO audit cost in Sydney?
A comprehensive technical SEO audit in Sydney typically ranges from $1,500 to $5,000, depending on site complexity, number of pages and CMS platform. Our audits include crawl analysis, a Core Web Vitals assessment, a structured data review, indexation checks and a prioritised action plan.
How long does it take to see results from technical SEO?
Critical fixes like indexation errors can show results within days. Core Web Vitals improvements reflect in CrUX data within 28 days. Broader ranking improvements usually appear within 4 to 12 weeks, as Google reprocesses your site architecture.
What is the difference between a technical SEO audit and an SEO audit?
A full SEO audit covers technical SEO, on-page content, keyword gaps and your backlink profile. A technical SEO audit focuses on infrastructure: the crawling, indexation, speed and structural issues that stop Google evaluating your content properly. Technical is the foundation, so we recommend starting there before layering in content and authority building.
How do you fix Core Web Vitals issues?
It depends on the failing metric. LCP failures usually come from unoptimised hero images or slow server response: we fix them with WebP conversion, lazy loading, an image CDN and server caching. CLS usually comes from images without set dimensions or injected content, fixed with width and height attributes and reserved space. INP needs a JavaScript audit and deferred loading of non-critical scripts.
How do you handle technical SEO for JavaScript-heavy sites?
Googlebot renders JavaScript in a second wave after the initial crawl, which can delay indexation significantly. We audit how your JavaScript content renders, identify above-the-fold content that should be server-side rendered or pre-rendered, configure dynamic rendering where appropriate, and check in Search Console that Google sees the same content as users.
Do you provide technical SEO for Shopify, WordPress, and custom CMS platforms?
Yes. We work across Shopify, WooCommerce, WordPress, Webflow, custom-built platforms and enterprise CMSs including Sitecore, Adobe AEM and Contentful. Each has its own constraints. Shopify’s duplicate product URLs under /collections/ and /products/, for example, need careful canonical configuration.
