Technical SEO audits your engineering team can actually ship
We review your site's code, structure and infrastructure across more than 100 checks, then hand your developers a prioritized plan with the URLs, the fix and the expected impact for every issue.
Why it matters
Most traffic problems on established sites are technical. A template change makes 400,000 filter pages indexable. A JavaScript framework hides product copy from crawlers. A migration leaves redirect chains that leak authority for years. These issues rarely show up in a dashboard until rankings have already slipped.
A technical SEO audit finds them systematically. We crawl the site the way Googlebot and AI crawlers do, compare that against Search Console and your server logs, and grade every area that affects whether your pages get crawled, indexed, ranked and cited.
What we look at
Crawling & indexation
- Index coverage and excluded pages
- Crawl budget and wasted crawl on low-value URLs
- Canonical tags and duplicate content
- Noindex, robots.txt and meta robots conflicts
- Faceted navigation and URL parameters
Architecture & internal linking
- Site hierarchy and click depth
- URL structure and consistency
- Orphan pages and internal link equity
- Navigation, breadcrumbs and pagination
Rendering & JavaScript
- Server-side vs client-side rendered content
- Content and links missing from initial HTML
- Hydration issues on React, Vue and Next.js sites
- What AI crawlers that do not run JavaScript can see
Performance & Core Web Vitals
- Largest Contentful Paint (LCP)
- Interaction to Next Paint (INP)
- Cumulative Layout Shift (CLS)
- Image, font and third-party script weight
Structured data
- Product, Article, Organization and FAQ schema
- Breadcrumb and sitelinks markup
- Validation errors and missing required fields
- Entity consistency across templates
Status codes & redirects
- 404s, soft 404s and 5xx errors
- Redirect chains and loops
- JavaScript and meta-refresh redirects
- HTTP to HTTPS and www consistency
Sitemaps & crawler directives
- XML sitemap coverage, freshness and errors
- Image and video sitemaps
- robots.txt rules for search and AI crawlers
- Search Console and Bing Webmaster configuration
International & mobile
- hreflang setup and return-tag errors
- Country and language URL strategy
- Mobile-first rendering parity
- Open Graph and social metadata
What you receive
Index Scorecard
Every check graded A to F with a short explanation, priority and owner, so you can track progress as fixes ship.
Fix Guide
The why and how behind each issue, with sample code, ticket-ready acceptance criteria and alternatives for your stack.
URL Supplement
The exact URLs, templates and files affected by each issue, ready to hand to engineering.
How it runs
Access
Search Console, analytics, crawl permission and, for large sites, server logs.
Crawl
Full crawl with and without JavaScript rendering, plus log and index analysis.
Grade
Each area graded and prioritized by traffic and revenue impact.
Walkthrough
We review the findings with your developers and adapt fixes to your stack.
Verify
We QA each fix after release and confirm the issue is resolved.
This is for you when…
- You manage a large or fast-growing site and organic traffic has stalled or dropped
- You are planning a redesign, replatform or new framework
- Engineering needs a prioritized, ticket-ready SEO backlog
- You have never had a thorough technical review
Look elsewhere when…
- You need someone to write code in your CMS (we spec and verify; your team implements)
- You want a quick read on one section only (see the Critical Issues Audit)
Technical SEO Audit questions
What does a technical SEO audit include?
It covers crawling and indexation, site architecture, internal linking, JavaScript rendering, Core Web Vitals, structured data, redirects, sitemaps, robots.txt, international setup and mobile parity. Each area is graded in the Index Scorecard with the affected URLs and a recommended fix.
How long does a technical SEO audit take?
Timing depends mostly on site size and how quickly access is set up. Smaller sites can be audited in a few weeks; multi-million URL sites with log file analysis take longer. We confirm the timeline in the proposal before work starts.
Do you implement the fixes?
We write the recommendations, sample code and ticket criteria, walk your developers through them and verify each fix after release. Your engineering team or web agency implements the changes in your codebase and CMS.
What is the Index Scorecard?
It is our graded summary of the audit. Every check gets an A to F grade, a priority, an owner and a status, so stakeholders can see what is broken and engineering can track what has been fixed.
What access do you need?
Google Search Console, your analytics platform, permission to crawl the site, a list of priority sections or markets, and your main competitors. Server log files are strongly recommended for sites over about 50,000 URLs.
Does the audit cover AI search and GEO?
Yes, at a technical level. We check whether AI crawlers can reach and render your pages and whether your structured data is consistent. For tracking how AI assistants mention and cite your brand, see our AI Search Visibility program.
