Industry Insight
Technical Problems Block 40% of Pages From Ranking Regardless of Content Quality or Link Authority
Google's crawlers cannot rank pages they cannot access, cannot index pages with canonical errors, and cannot evaluate content speed that fails Core Web Vitals thresholds. Technical SEO audits consistently find that between 30 and 50% of pages on typical business websites have one or more technical issues preventing full ranking potential — crawl blocks, duplicate content without proper canonicals, broken internal links, missing structured data, or render-blocking JavaScript. Fixing these issues unlocks ranking potential that content investment alone cannot deliver.
The Problem
Content Cannot Fix Broken Foundations
Content and links are the most visible parts of SEO, but they cannot overcome technical problems. If Google cannot efficiently crawl your site, duplicate versions of your pages compete with each other, or your Core Web Vitals sit in the bottom quartile of sites in your category, content quality becomes irrelevant.
The average Australian business site we audit has 3 to 5 Critical-level technical issues that have never been identified. Because technical issues are invisible to users and introduced gradually through developer changes and CMS updates, they accumulate undetected for months or years.
A single misconfigured robots.txt rule can exclude your most important service pages from Google's index. A canonical loop between two pages can split authority indefinitely. A 5-second LCP turns an otherwise effective page into a bounce problem. These are not edge cases: they are the expected state of most sites that have not had a structured technical audit.
Our Technical SEO Service
Our Technical SEO Audit: Six Core Components
Crawl and Indexation Audit
Full Screaming Frog crawl of every URL on your domain. Every robots.txt rule tested, every canonical tag verified, every noindex tag audited. XML sitemap accuracy checked against actual indexed pages in Search Console. Orphan pages identified and resolved.
Core Web Vitals Optimisation
PageSpeed Insights and Chrome CrUX field data reviewed per template type. LCP cause identified and fixed (image, TTFB or render-blocking resource). CLS root cause traced. INP interaction analysed. Every fix tracked against before-and-after Lab and Field data.
Structured Data Implementation
JSON-LD schema applied for all relevant types: Service, LocalBusiness, FAQPage, BreadcrumbList, Article, Product and AggregateRating. Every implementation validated using Google's Rich Results Test before deployment. Schema errors in Search Console resolved within 48 hours.
JavaScript Rendering Diagnosis
Googlebot rendering test using Fetch as Google and Screaming Frog JavaScript crawl mode. Identifies content hidden behind client-side rendering, React hydration delays, and script-loaded elements that Googlebot cannot reliably access during initial indexation.
URL Architecture and Redirects
Redirect chain identification and consolidation to direct 301s. Redirect loops resolved. 404 errors triaged and either redirected or removed from internal linking. URL parameterisation strategy for eCommerce sites including canonical and robots.txt implementation.
Search Console Integration
Complete review of crawl errors, coverage gaps, manual action flags, Core Web Vitals report, mobile usability errors and Index Coverage warnings. Every flagged URL traced to root cause with specific resolution. New Search Console property setup where needed.
Our Process
Technical SEO Audit Process
Crawl and Data Collection
We run Screaming Frog against your live domain, pull your full Search Console data export, grab Core Web Vitals from PageSpeed Insights per template type, and request server log files where available. Data collection takes 1 to 2 days.
Issue Identification and Categorisation
Every issue found is categorised by type and assigned a severity rating: Critical (blocks indexation), High (definite ranking impact), Medium (ranking impact at scale), Low (best practice improvement). Severity is tied to expected outcome, not just SEO convention.
Root Cause Analysis
For every Critical and High issue we document the root cause, not just the symptom. A page returning noindex might be deliberately set, accidentally inherited from a template setting, or the result of a plugin conflict. Fixing the symptom without identifying the cause produces a recurrence.
Fix Specification Writing
Every identified issue is converted to a developer-ready fix specification including the affected URLs, the cause, the exact fix instruction, the expected outcome, implementation difficulty, and estimated developer hours. Usable by any developer without further briefing.
Implementation and Verification
We apply fixes directly where possible (meta tags, canonical adjustments, robots.txt, structured data, image optimisation). Where developer access is required, we provide the spec and verify the fix after deployment. Every fix verified in Screaming Frog and Search Console.
Monitoring and Re-Audit
After implementation, we set up automated monitoring in Search Console for new crawl errors. We schedule a re-audit at the 90-day mark to measure indexation improvements and identify any new issues introduced by site updates or developer deployments.

Results
Technical SEO results for Australian sites
Melbourne, VIC
Challenge: A Melbourne homewares retailer had 12,000 product pages but only 1,800 indexed in Google. Faceted navigation was generating over 40,000 crawlable URL variants. Search Console showed 78% of the crawl budget consumed by filter page combinations rather than actual products.
Work done: Implemented canonical tags on all parameter URLs, added a robots.txt disallow for faceted navigation parameters, corrected 14 conflicting canonical tag implementations on category pages, removed 220 redirect chains of 3 or more hops, and fixed 6 structured data errors flagged in Rich Results Test.
Sydney, NSW
Challenge: A legal firm's website had strong content but stalled rankings. An audit revealed 34 pages blocking Google via a misconfigured robots.txt rule, duplicate meta descriptions across 41 service pages, and a 4.2-second LCP caused by an unoptimised hero image loaded without proper attributes.
Work done: Corrected the robots.txt disallow blocking service pages written in the past 8 months, rewrote and uniquified meta descriptions for all 41 service pages, compressed and converted the hero image from 2.1MB PNG to 180KB WebP with explicit width and height attributes to eliminate CLS.

Technical SEO Across Every Platform
Why Us
Why Businesses Choose Our Technical SEO
We use the tools Google recommends
Screaming Frog, Google Search Console, PageSpeed Insights and Chrome CrUX are the tools Google itself references when publishing technical SEO guidance. We do not use proprietary black-box scoring systems that do not correlate with actual rankings.
Fix specifications your developer can actually use
Every technical issue we find is converted into a developer brief with the affected URLs, the root cause, the exact fix instruction, and the expected outcome. No vague recommendations requiring further interpretation.
Platform-specific expertise, not generic checklists
A technical audit for a Shopify store is fundamentally different from one for a custom Next.js application. We have run audits on 15 different platform types and know the specific issue patterns each produces.
We verify every fix after implementation
Fixes applied incorrectly or to the wrong URLs are common. We run a verification crawl after every round of implementation to confirm the issue is resolved before marking it closed.
Crawl budget analysis for large sites
For sites with more than 5,000 URLs, crawl budget management is often the single highest-impact technical intervention available. We use Screaming Frog log file analysis to map exactly how Google spends its crawl time on your domain.
Schema markup that qualifies for rich results
We write structured data against Google's actual rich result requirements, not just the schema.org specification. These differ in important ways. Our implementations regularly achieve Featured Snippets, FAQ rich results and review stars within 30 to 60 days.

Answer Engine Optimisation
AI Crawlers Require the Same Technical Foundations as Google — Broken Sites Don't Get Cited
AI answer engines use automated crawlers to index and evaluate content for inclusion in generated responses. Sites with crawl blocks, canonical errors, JavaScript rendering failures, or structured data markup errors are less likely to be crawled comprehensively, indexed, and cited. Technical SEO creates the infrastructure foundation that both Google's algorithm and AI citation engines require to access, understand and trust your content.
Client Results
Technical SEO Clients Unblocking Ranking Potential
"The technical audit found 340 pages blocked in robots.txt that we had never intended to block — including our entire blog. Four weeks after removing the block and submitting to Search Console, organic traffic to the blog increased by 612%. The content was always there; Google just couldn't access it."
"Core Web Vitals were failing on every product page due to uncompressed images and a render-blocking third-party chat widget. After the performance fixes, LCP improved from 8.2 seconds to 1.9 seconds. Our product page rankings improved across the board within six weeks."
"We had 180 canonical tags pointing to the wrong domain after a site migration six months earlier. Every page was telling Google to index the old staging domain instead of the live site. Fixing the canonicals moved 140 previously unranked pages back into position within eight weeks."
