Technical SEO Audits

Technical SEO Audit Services

In-depth diagnostics that surface every issue and turn them into a clear, fix-first roadmap.

Your site can look fantastic and still be held back by hidden technical blockers: crawl traps, duplicate URLs, slow templates, messy redirects, JavaScript rendering quirks, and tracking gaps. Our Technical SEO Audit goes far beyond automated scans. We combine tool output with hands-on investigation and real-world SEO judgment to show you exactly what’s working, what’s broken, and what to fix first so search engines can fully discover, understand, and rank your content.

What you get (deliverables you can act on)

• Executive Summary (plain English): The key problems, why they matter, and the expected impact on visibility and conversions.
• Issue Scorecard: Pass / Warn / Fail across every audit category with severity and scope.
• Prioritised Action Plan: Effort vs. impact matrix, with step-by-step fixes and screenshots.
• Dev-ready Tickets: Clear requirements + acceptance criteria for engineering/design/content.
• Architecture & Linking Recommendations: How to restructure URLs and internal links for crawlability and topical authority.
• Schema/Rich Result Plan: Exactly which structured data to implement and how.
• QA & Verification Checklist: How to test fixes in staging and production; what to monitor post-release.
• Walkthrough Call (optional): We explain the why behind each fix so your team can move fast with confidence.
• Re-test & Validation (optional): We’ll verify the changes and update the scorecard.

What we cover (deep dive)

1) Crawlability & Indexation

• Robots directives: robots.txt, noindex, nofollow, x-robots-tag, and header/meta conflicts.
• XML sitemaps (HTML & media sitemaps too): completeness, freshness, and indexation parity.
• Crawl depth & discovery: key templates within 3 clicks; orphaned/low-linked pages.
• Canonicals & duplicates: self-referencing canonicals, canonical loops, HTTP/HTTPS/www variants, trailing slash rules.
• Parameter handling & session IDs: prevent infinite crawl spaces and duplicate content.
• Pagination & infinite scroll: rel signals, load-more patterns, and discoverability safeguards.
• Soft 404s and thin/expired pages: correct handling and consolidation.

2) Site Architecture & Internal Linking

• URL strategy: consistency, hierarchy, and future-proofing for scale (categories, filters, locales).
• Hubs & spokes (topic clusters): ensure link equity flows to revenue pages.
• Navigation, breadcrumbs, footers: crawl path clarity and anchor-text hygiene.
• Canonical clusters to reduce cannibalisation and strengthen primary targets.

3) Rendering & JavaScript

• Server-side vs client-side rendering: hydration timing, blocked resources, deferred content.
• Critical content in HTML where possible; fallback strategies for JS-only elements.
• Pre-rendering/SSR options for frameworks (React/Vue/Next/Nuxt/etc.).
• Lazy-loading safeguards (images/iframes) to avoid non-indexed content.

4) Performance & Core Web Vitals

• LCP, CLS, INP diagnostics (by template), image delivery (compression, dimensions, formats like WebP/AVIF), font loading, caching, and critical CSS.
• Mobile vs desktop performance; triage by highest-traffic templates.
• Third-party script governance (tags, sequence, consent impact) and bloat reduction.
• CDN, HTTP/2 or HTTP/3, TLS, and caching headers best practice.

5) Mobile-first & UX Fundamentals

• Responsive breakpoints, viewport config, tap targets, and mobile nav patterns.
• Interstitials and cookie/consent banners that harm crawlability or UX.
• Mixed content (HTTP assets on HTTPS pages), redirect hops, and 4xx/5xx stability.

6) Content Signals & On-Page Hygiene

• Titles, H1/H2 structure, meta descriptions at scale (templates + exceptions).
• Thin/duplicate detection and canonical consolidation strategy.
• Media optimisation (ALT text, captions, file naming, sitemaps).
• Entity coverage & intent alignment (without keyword stuffing).

7) Structured Data & Rich Results

• Organization, Product/Service, BreadcrumbList, FAQPage, Article, LocalBusiness, etc.
• Validation (syntax + logic), de-duplication, and mapping to actual SERP features worth targeting.

8) Local SEO Components (where relevant)

• Google Business Profile (GBP) & Microsoft Bing Places alignment with on-site NAP.
• LocalBusiness schema, location pages (unique content, internal links, CTAs, map embeds).
• Directory consistency (see our Local SEO services for ongoing management).

9) Technical Integrity & Accessibility

• Broken links, redirect chains/loops, 404/soft 404 design patterns and headers.
• XML sitemap health vs. Search Console coverage; index bloats and exclusions.
• Accessibility checks: headings order, ARIA basics, contrast, focus states, alt text (benefits SEO & UX).
• Security posture: HTTPS everywhere, HSTS, mixed content, canonicalisation of protocol/host.

10) Analytics, Tracking & Search Console

• GA4 / Search Console integration sanity: property alignment, filters, default channel grouping effects.
• Conversion/event tracking accuracy, consent-aware firing, and attribution pitfalls.
• UTM conventions to separate organic vs profile/referral sources (GBP/Bing, social).
• Annotations for deployments and migrations to tie fixes to outcomes.

11) Internationalisation (if applicable)

• hreflang completeness and correctness, region/language pairs, x-default usage.
• URL patterns per locale (folders vs subdomains), canonical alignment across translations.

12) E-commerce Specifics (if applicable)

• Faceted navigation guardrails (crawl + index rules for filters/sorts).
• Product canonicalisation, variants, availability, price/meta data, review markup.
• Pagination of PLPs, internal linking from PDPs, and feed/schema coherence.

Why a Technical SEO Audit matters

A strong SEO strategy is built on a technically sound site. Without it, even brilliant content and links underperform. Our audit helps you:

• Remove ranking blockers and indexation waste.
• Improve UX and performance across devices (Core Web Vitals).
• Consolidate authority and eliminate cannibalisation.
• Future-proof your site architecture for content growth, regions, and new product lines.

Our SEO audit workflow

1. Access & Discovery – We gather read access (CMS/GTM/GA4/Search Console), your goals, and any known issues.
2. Evidence Gathering – Crawls, template sampling, server/header checks, rendering tests, and SERP spot-checks.
3. Findings & Priorities – Scorecard + effort/impact roadmap, with dev-ready tasks and owner assignments.
4. Fix Support – We can work with your devs/designers to implement changes, or provide advisory tickets.
5. QA & Validation – Staging checklists, Search Console review, and metrics monitoring.
6. Retest (optional) – Re-crawl, update scorecard, and lock in a maintenance plan if you wish.

What we need from you

• Read access to Search Console, GA4, and (if applicable) GTM.
• A staging URL (ideal) or dev notes for template-level changes.
• Any previous audits/migration notes and your priority pages/KPIs.

Common SEO issues we fix (fast wins + big lifts)

• Mixed www/non-www/HTTP/HTTPS versions and duplicate page sets.
• Auto-generated parameters bloating the index; crawl budget wasted on thin pages.
• Canonical tags pointing to non-indexable or redirected URLs.
• JS rendering that hides key content from bots.
• Slow hero images/fonts hurting LCP; layout shifts hurting CLS; interaction lag hurting INP.
• Redirect chains after site moves; legacy 301s that should be consolidated.
• Orphaned revenue pages with no internal links from hubs.
• Schema present but invalid – or missing where it would unlock rich results.

FAQs About Technical SEO Audits

Will this audit include content or link building?
We focus on technical foundations. We’ll flag content/authority opportunities and can support via our Monthly SEO or Strategy services.

Can you fix historical indexing mistakes?
We can’t change the past, but we can consolidate duplicates, correct canonicals/redirects, and guide Google to the right URLs going forward.

How quickly will we see results?
Some fixes (redirects/canonicals/crawl traps) can move the needle quickly; Core Web Vitals and architecture changes compound over weeks to months.
