Content and links cannot compensate for a broken technical foundation. Crawl issues, indexation gaps, duplicate content, slow pages, and schema errors silently suppress rankings regardless of how good the content is. Oddtusk conducts deep technical SEO audits that surface every issue blocking organic performance, prioritise fixes by revenue impact, and provide implementation-ready documentation your development team can act on immediately.
A technical audit without a fix plan is a report. We deliver both.
Most technical SEO audits produce long lists of issues with no prioritisation, no business context, and no implementation guidance. The development team ignores them. Oddtusk delivers technical audits that prioritise every finding by its estimated impact on organic traffic and revenue, provide specific implementation instructions for each fix, and flag the issues that need immediate attention separately from those that can be addressed in a regular sprint cycle.
Crawlability and Indexation Analysis
We map every URL across your site against GSC indexation data to identify pages that should be indexed but are not, pages that are indexed but should not be, crawl budget waste from low-value URLs, and robots.txt or noindex directives blocking content that needs to rank. Crawl depth, internal link accessibility, and orphan page identification are all covered in full.
Core Web Vitals Diagnosis
We audit every Core Web Vitals metric across both mobile and desktop using field data from GSC and lab data from PageSpeed Insights. The specific elements causing each failure are identified and documented with targeted fix recommendations for your development team rather than generic improvement suggestions.
Duplicate Content and Canonical Audit
Duplicate content dilutes ranking authority and wastes crawl budget. We identify every instance of duplicate, near-duplicate, and thin content across the site including pagination issues, URL parameter duplication, www and non-www variations, HTTP and HTTPS conflicts, and incorrect canonical configurations. Each instance is documented with the correct resolution.
Redirect Chain and Error Mapping
Redirect chains and loops waste crawl budget, dilute link equity, and slow page load. We map every redirect across the site, identify chains of two or more hops, flag soft 404s being treated as 200s, and document every 4xx and 5xx error with its source URLs. Each redirect issue comes with the correct single-hop resolution to ensure link equity flows directly to the intended destination URL.
Schema Markup Validation
Every schema implementation across the site is validated against Google's Rich Results Test and Schema Markup Validator. Missing required properties, incorrect schema types, validation errors, and opportunities for additional schema coverage are all documented with ready-to-implement code blocks for each page type.
Impact-Prioritised Fix Plan
Every finding in the audit is assigned a priority tier based on its estimated impact on crawlability, indexation, ranking, and organic revenue. Critical issues blocking indexation or causing significant ranking suppression are flagged separately from high and medium priority improvements. Each finding includes implementation instructions, the affected URLs, and the expected outcome so your development team can act without needing to interpret the audit data themselves.
Technical SEO Audit Outcomes Across Businesses and Ecommerce Brands We Have Unblocked.
Sites with indexation issues caused by incorrect noindex tags, robots.txt blocks, or sitemap misconfiguration typically see 60 to 70 percent more pages correctly indexed within 30 days of critical fix implementation.
Implementing targeted Core Web Vitals fixes identified in the audit consistently improves CWV scores by 35 to 45 percent across pages with the highest organic traffic value.
Sites that implement critical and high-priority technical fixes within 60 days consistently double organic traffic within 90 days as previously suppressed pages gain indexation and Core Web Vitals ranking signals improve.

Straight answers to the questions that matter.
A technical SEO audit is a systematic review of every technical element that affects how search engines crawl, index, and rank a website. It covers crawlability, indexation, site speed and Core Web Vitals, duplicate content and canonicalisation, redirect integrity, XML sitemaps, robots.txt configuration, schema markup, internal link structure, and mobile usability. The output is a prioritised list of issues with implementation guidance so every finding can be acted on immediately.
A full technical audit should be conducted annually for stable sites and after any significant site migration, platform change, or major content restructure. For ecommerce sites that add products and categories regularly, a lighter quarterly crawl review is recommended to catch indexation and duplicate content issues before they compound. Sites that have experienced significant unexplained traffic drops should be audited immediately regardless of when the last audit was done.
Our primary audit tools are Screaming Frog for full site crawl data, Google Search Console for indexation and Core Web Vitals field data, PageSpeed Insights for lab-based speed analysis, Ahrefs for redirect and backlink profile review, Google's Rich Results Test and Schema Markup Validator for structured data validation, and GTmetrix for waterfall-level load performance. Tool selection is adapted based on site size, platform, and the specific issues surfaced in the initial crawl.
The audit service delivers a comprehensive report with an implementation-ready fix plan. For clients who require implementation support, we offer a separate implementation engagement where we work directly with your development team or inside the CMS to execute the priority fixes. For standalone audit engagements, the report is structured so your development team can implement without additional briefing — every fix includes specific instructions, affected URLs, and expected outcomes.
Audit timeline depends on site size and complexity. A small to medium business site of up to 500 URLs is typically completed within 5 to 7 business days. Large ecommerce sites with 5,000 to 50,000 URLs take 10 to 15 business days. Enterprise sites or those with complex JavaScript rendering, Multisite setups, or multiple regional domains require individual scoping. Timeline is confirmed at project kickoff after a preliminary crawl to assess site complexity.
Yes. JavaScript-rendered sites including React, Angular, Vue, and Next.js applications require a different crawl approach. We configure Screaming Frog with JavaScript rendering enabled and cross-reference the rendered DOM against the raw HTML to identify content that is invisible to Googlebot's initial crawl. Rendering delays, client-side redirect issues, and content that exists only in the JS bundle but is not pre-rendered are all covered in the audit.
Yes, in combination with a content quality assessment. Core update drops are rarely caused by a single technical issue but technical problems can compound the impact of content quality signals or prevent recovery after an update. A technical audit identifies whether crawl issues, indexation gaps, or page experience signals are contributing to the drop alongside the content and E-E-A-T factors that typically drive core update impacts. Both layers need to be addressed for full recovery.
Yes. Ecommerce audits have specific requirements beyond standard site audits including faceted navigation crawl management, duplicate product URL handling from sorting and filtering parameters, thin product page identification, out-of-stock page strategy, category page content depth, and Product schema validation across large URL sets. We have experience auditing WooCommerce, Shopify, and Magento catalogues and adapt the audit methodology to the specific challenges of each platform.
We need view-level access to Google Search Console and read-only access to Google Analytics 4. For sites behind authentication or staging environments, temporary access credentials or an IP whitelist for our crawl tool are required. A sitemap URL and confirmation of the canonical domain format speeds up the initial setup. We do not require CMS access for the audit itself, though it is needed if we are also handling implementation. A brief onboarding call to discuss any known issues is scheduled at project start.
The audit is delivered as a structured document covering an executive summary for non-technical stakeholders, a detailed findings section with all issues categorised by type and priority, an implementation roadmap organising fixes into critical, high, medium, and low priority batches, and supporting data files in CSV format for URL-level findings. A walkthrough call is included with every audit to present key findings, answer questions, and align on the fix implementation sequence.
