Claude Code for Technical SEO: Automate Audits, Schema, and Site Architecture

Technical SEO is the backbone of search visibility. Without a properly crawlable site, clean architecture, and valid structured data, even the best content struggles to rank. The challenge is that technical SEO is also extraordinarily labor-intensive. A single audit of a mid-sized site can take 20 to 40 hours of manual work, and the results start going stale the moment your team pushes the next deployment.

This is where Claude Code transforms the workflow. Unlike browser-based AI assistants, Claude Code operates directly in your terminal and interacts with your actual codebase. It can read files, search across directories, edit code, and run commands. That means it can do the same work a technical SEO specialist does when they open a project in their editor, but at a speed and consistency that manual processes simply cannot match.

In this guide, we will walk through every major technical SEO task you can automate with Claude Code, from comprehensive site audits and schema markup generation to site architecture optimization and migration management. If you are new to using Claude Code for SEO in general, start with our complete guide to Claude Code for SEO first.

Why Technical SEO Needs AI Automation

The scope of technical SEO has expanded significantly over the past several years. Google now evaluates hundreds of technical signals, from Core Web Vitals and mobile usability to structured data validity and crawl efficiency. For any site with more than a handful of pages, managing these factors manually is becoming unsustainable.

The Scale Problem

Consider a typical e-commerce site with 5,000 product pages. A manual audit of meta tags alone requires reviewing 5,000 title tags, 5,000 meta descriptions, and 5,000 canonical tags. That is 15,000 individual checks before you even look at heading structure, schema markup, or internal links. Claude Code can scan the entire codebase and report every issue in a single session.

Beyond scale, there are three other compelling reasons to automate technical SEO:

Consistency. Manual audits vary based on who performs them and when. Automated checks apply the same standards every time, eliminating human error from repetitive tasks.
Speed of implementation. Identifying a problem is only half the battle. Claude Code can both find issues and implement fixes in the same session, collapsing what used to be a two-step (audit then fix) process into one.
Continuous monitoring. Instead of running audits quarterly, you can integrate Claude Code into your deployment pipeline to catch issues before they reach production. This is especially valuable for teams practicing continuous technical SEO optimization.

The result is a fundamental shift in how technical SEO teams operate. Instead of spending 80% of their time on detection and 20% on strategy, they can flip that ratio, using Claude Code for the repetitive work while focusing human expertise on strategic decisions. Our technical SEO services leverage exactly this approach for client engagements.

Automated Site Auditing with Claude Code

A comprehensive SEO audit typically covers dozens of checkpoints. Claude Code can handle most of these by reading your project files directly. Here is what a Claude Code audit workflow looks like in practice.

Scanning for Missing and Duplicate Meta Tags

Claude Code can search your entire project for page components or HTML files, extract title tags and meta descriptions from each one, and produce a report flagging pages that are missing metadata, have duplicate titles, or exceed character limits. For a Next.js App Router project, it reads the exported metadata objects. For traditional HTML sites, it parses the <head> section of every file.

# Example prompt for Claude Code

"Scan every page.tsx in src/app/ and list all exported metadata objects.

Flag any page missing a title, description, or canonical URL.

Flag duplicate titles across pages. Output as a markdown table."

Heading Hierarchy Validation

Proper heading structure (a single H1 per page, logical H2 and H3 nesting) matters for both accessibility and SEO. Claude Code can scan every page component, extract all heading elements, and flag violations: pages with no H1, pages with multiple H1 tags, or headings that skip levels (for example, jumping from H2 to H4).

Broken Internal Link Detection

One of the most valuable audit checks is verifying that every internal link in your codebase points to a route that actually exists. Claude Code can extract all href attributes from your templates, compare them against your actual page routes, and report any links that lead to pages that do not exist. This is particularly useful after restructuring or deleting pages.

Pro Tip

Run the broken link audit after every major deployment or page restructure. Claude Code can compare your sitemap URLs against your filesystem routes to catch discrepancies instantly.

Generating Prioritized Audit Reports

Rather than producing a flat list of issues, you can instruct Claude Code to categorize findings by severity (critical, warning, informational) and by type (meta tags, headings, links, schema, performance). This mirrors the output format of enterprise audit tools like Screaming Frog or Sitebulb, but it is generated directly from your source code rather than from a crawl. The advantage is that you catch issues before deployment, not after.

Schema Markup Implementation at Scale

Structured data is one of the highest-impact technical SEO investments you can make. It enables rich results, improves how search engines understand your content, and plays an increasingly important role in AI-generated answers. The challenge has always been implementation at scale. Writing JSON-LD for hundreds of pages is tedious, error-prone, and difficult to maintain. Claude Code solves this. For a deeper exploration of structured data, see our complete schema markup guide.

Reading Content and Generating Appropriate Schema Types

Claude Code can read the content of a page, determine what schema type is appropriate, and generate valid JSON-LD. For a blog post, it creates Article schema with headline, author, datePublished, and publisher properties. For a product page, it generates Product schema with name, description, price, and availability. For a services page, it uses Service or ProfessionalService schema. The key advantage is that it reads the actual content, so the schema accurately reflects what is on the page.

Implementing Multiple Schema Types

Most pages benefit from multiple schema types. A blog post typically needs Article schema, BreadcrumbList schema, and often FAQPage schema if it contains a questions section. Claude Code can generate all three simultaneously, properly formatted and nested. Here is what you might ask it to do:

# Example prompt for Claude Code

"For every blog post in src/app/blog/, check if the page has

Article, BreadcrumbList, and FAQPage schema. If any schema type

is missing, generate it based on the page content and add it

to the component. Use the existing schema patterns from

src/app/blog/aeo-answer-engine-optimization-definitive-guide/page.tsx

as the reference template."

Schema Types Claude Code Handles Well

Content Schema

Article and BlogPosting
FAQPage with Question/Answer pairs
HowTo with step-by-step instructions
BreadcrumbList for navigation paths

Business Schema

LocalBusiness with address and hours
Product with pricing and availability
Organization with contact details
Service and ProfessionalService

Validating Existing Schema Across Hundreds of Pages

If your site already has schema markup, Claude Code can audit it across every page. It checks for required properties, validates that property values match the actual page content (for example, verifying the schema headline matches the H1), flags deprecated schema types, and ensures JSON-LD syntax is valid. On a 200-page site, this validation takes minutes instead of the hours it would require manually.

Updating Schema When Content Changes

One of the most common schema problems is stale data. An article gets updated but the dateModified property still shows the original publication date. Product prices change but the schema still reflects old pricing. Claude Code can scan for these mismatches and update schema properties to reflect current content, which is especially useful when combined with our schema markup generator tool.

Site Architecture and Internal Linking

Site architecture determines how search engines discover, crawl, and rank your pages. A well-structured site ensures that link equity flows efficiently to your most important pages and that crawlers can reach every page within a reasonable number of clicks from the homepage. Claude Code can analyze and optimize this structure directly from your source files.

Mapping Site Structure and Identifying Orphan Pages

Orphan pages (pages that exist but have no internal links pointing to them) are invisible to search engines unless they appear in your sitemap. Claude Code can build a complete map of your site by listing every route in your project, then cross-referencing that list against every internal link in your templates. Any page that exists as a route but is never linked from another page gets flagged as an orphan.

Building Internal Linking Matrices

Strategic internal linking is one of the most effective ways to distribute page authority and help search engines understand topical relationships. Claude Code can generate an internal linking matrix by analyzing all pages in a content cluster and identifying which pages should link to each other based on topic relevance and keyword targeting. For example, in a hub-and-spoke architecture, it can verify that every spoke page links back to its hub and that the hub links to all spokes.

Internal Linking Best Practices Claude Code Can Enforce

Every page should have at least 3 to 5 internal links pointing to it
Hub pages should link to all related spoke pages within the same cluster
Anchor text should be descriptive and relevant to the target page
No page should be more than 3 clicks from the homepage
New content should be linked from existing high-authority pages

Generating Breadcrumb Navigation

Breadcrumbs serve both users and search engines by making site hierarchy explicit. Claude Code can generate breadcrumb components and corresponding BreadcrumbList schema based on your URL structure. For a page at /blog/claude-code-technical-seo-automation, it automatically creates the path: Home, Blog, Claude Code for Technical SEO.

Creating XML Sitemaps Programmatically

Rather than manually maintaining a sitemap, Claude Code can generate one by scanning your project routes. It reads every page file, extracts the URL path, pulls the last modified date from git history or file metadata, assigns priority values based on page depth, and outputs a valid XML sitemap. For frameworks like Next.js, it can also build the sitemap.ts configuration that generates sitemaps dynamically at build time.

Core Web Vitals Optimization

Core Web Vitals (LCP, INP, and CLS) are confirmed Google ranking factors. Optimizing them requires hands-on code changes, which makes Claude Code an ideal tool for the job. Unlike external audit tools that can only tell you what is wrong, Claude Code can both diagnose and fix performance issues in the same session. For the full picture on performance optimization, see our guide on Core Web Vitals optimization in 2026.

Identifying Render-Blocking Resources

Render-blocking CSS and JavaScript are among the most common causes of poor Largest Contentful Paint (LCP) scores. Claude Code can scan your HTML templates and layout files to identify stylesheets loaded in the <head> without media attributes and scripts without async or defer attributes. It can then refactor these to load asynchronously, inline critical CSS, or defer non-essential scripts.

Optimizing Image Loading

Images are typically the largest elements on a page and the primary driver of LCP performance. Claude Code can audit your image implementation across the entire site, checking for missing loading="lazy" attributes on below-the-fold images, missing width and height attributes (which cause layout shift), oversized images served without responsive srcset declarations, and images without descriptive alt text. It can then implement the fixes across all affected files in one operation.

Reducing JavaScript Bundle Sizes

Excessive JavaScript impacts both LCP and Interaction to Next Paint (INP). Claude Code can analyze your imports to identify heavy libraries that could be replaced with lighter alternatives, find unused code that can be removed through tree-shaking, detect components that should be dynamically imported (lazy loaded) rather than included in the main bundle, and suggest code-splitting strategies based on route boundaries.

Fixing Cumulative Layout Shift

CLS issues stem from elements that shift position after the initial render. Claude Code can scan for the most common causes: images and iframes without explicit dimensions, dynamically injected content above existing elements, web fonts that cause Flash of Unstyled Text (FOUT), and ads or embeds without reserved space. For each issue, it can implement the appropriate fix, whether that is adding dimension attributes, reserving space with CSS, or implementing font-display strategies. Learn more about these performance factors in our website speed optimization guide.

Robots.txt and Crawl Optimization

Crawl budget management becomes critical as sites grow. You need search engines to spend their crawl budget on your most valuable pages, not on filter combinations, pagination endpoints, or staging URLs. Claude Code can help generate, validate, and optimize your robots.txt and crawl directives.

Generating and Validating Robots.txt

Claude Code can review your entire site structure and generate a robots.txt file that blocks crawling of admin areas, API endpoints, search result pages, and other low-value URLs while ensuring all important content pages remain accessible. It can also validate an existing robots.txt against your site structure to verify that no important pages are accidentally blocked.

Managing Crawl Budget Effectively

For large sites, Claude Code can audit your internal link structure and XML sitemaps to identify pages that receive excessive crawl attention (such as pagination endpoints) and pages that are under-crawled (such as deep content pages). It can then recommend and implement changes to your link architecture and sitemap priority values to redistribute crawl budget toward your highest-value pages.

Identifying and Fixing Crawl Errors

By cross-referencing your codebase with server configuration files, Claude Code can identify common crawl issues: pages returning incorrect status codes, redirect chains, pages blocked by robots.txt but still linked internally, and noindex pages included in the sitemap. This type of cross-system analysis is where Claude Code adds the most value, because it can read multiple configuration files simultaneously and identify conflicts that would be difficult to spot manually.

Migration and Redirect Management

Site migrations are among the highest-risk technical SEO events. A botched migration can destroy years of organic traffic overnight. Claude Code significantly reduces that risk by automating the most error-prone parts of the process: redirect mapping, implementation, and post-migration validation.

Generating Redirect Maps

When migrating to a new URL structure, Claude Code can read your old site architecture and your new site architecture side by side, then generate a comprehensive redirect map. It uses URL patterns, page titles, and content similarity to match old URLs to their new equivalents. For example, it can determine that /services/seo-audit should redirect to /services/technical-seo based on content overlap.

Bulk 301 Redirect Implementation

Once the redirect map is finalized, Claude Code can implement the redirects in whatever format your infrastructure requires. For Next.js, it writes the redirects array in next.config.ts. For Apache, it generates .htaccess rules. For Nginx, it creates the appropriate rewrite directives. For Netlify, it builds the _redirects file or netlify.toml rules. Having a single tool handle both the mapping and implementation eliminates the translation errors that commonly occur when one person creates the map and another implements it.

Detecting Redirect Chains and Loops

Redirect chains (A redirects to B redirects to C) waste crawl budget and dilute link equity. Redirect loops (A redirects to B redirects to A) break pages entirely. Claude Code can trace every redirect path in your configuration, flag chains longer than one hop, and identify loops. It can then flatten chains by updating each redirect to point directly to the final destination.

Post-Migration Audit Automation

After a migration goes live, you need to verify that every old URL correctly resolves to its new destination and that no pages return 404 errors. Claude Code can compare the pre-migration URL inventory against the live site, test every redirect, and flag any URLs that do not resolve correctly. This post-migration validation is where many teams cut corners due to time pressure, but automation makes it trivial.

Practical Workflow Examples

Here are four specific workflows you can execute with Claude Code today. Each includes the type of prompt you would use and what to expect as output.

Workflow 1: Full Meta Tag Audit

Goal: Identify every page with missing, duplicate, or poorly optimized meta tags.

"Read every page file in src/app/ recursively. For each page,

extract the title, description, and canonical URL from the

metadata export. Create a markdown report with three sections:

1) Pages missing any meta field, 2) Duplicate titles or

descriptions, 3) Titles over 60 characters or descriptions

over 160 characters. Sort by severity."

Expected output: A structured markdown table with page paths, current values, and specific issues flagged per page.

Workflow 2: Bulk Schema Markup Generation

Goal: Add FAQPage schema to every blog post that contains a FAQ section but lacks structured data for it.

"Search all blog post pages for FAQ sections (look for headings

like 'FAQ' or 'Frequently Asked Questions'). For each page

that has FAQ content but no FAQPage schema, generate the

JSON-LD schema based on the actual questions and answers in

the content. Add it alongside the existing Article and

BreadcrumbList schemas."

Expected output: Updated page files with properly formatted FAQPage schema added, matching the existing schema patterns in the codebase.

Workflow 3: Orphan Page Detection

Goal: Find all pages that exist in the codebase but have no internal links pointing to them.

"List every route in src/app/ (each directory with a page.tsx).

Then search the entire codebase for internal links (href values

starting with /). Compare the two lists and report any routes

that are never linked from any other page. Also check if

these orphan pages appear in sitemap.ts."

Expected output: A list of orphan page URLs with recommendations for where to add internal links to each one.

Workflow 4: Redirect Chain Cleanup

Goal: Identify and flatten all redirect chains in your configuration.

"Read the redirects configuration in next.config.ts. Trace

every redirect chain (where the destination of one redirect

is the source of another). List all chains found. Then update

the configuration so every redirect points directly to the

final destination URL, eliminating intermediate hops."

Expected output: Updated next.config.ts with flattened redirects, plus a before/after summary showing the chains that were resolved.
