Our Technical SEO Services

Technical SEO Audit

We perform a detailed review of your website to identify crawl, indexing, performance, and structural problems.

Crawlability Analysis

We check whether search engine crawlers can access important pages efficiently.

Indexation Review

We identify pages that should or should not be indexed and investigate indexing inconsistencies.

Robots.txt Optimization

We review robots directives to make sure important content is not accidentally blocked.

XML Sitemap Optimization

We check whether sitemaps contain the right URLs and help search engines discover important pages.

Canonical Tag Review

We review canonical implementation to reduce duplicate URL confusion and consolidate signals where appropriate.

Redirect Audit

We identify redirect chains, loops, broken redirects, and incorrect status-code behavior.

Broken Link Fixes

We identify internal and external broken links that may create poor user experiences or crawling issues.

Page Speed Optimization

We review performance problems such as oversized assets, render-blocking resources, heavy scripts, and slow-loading pages.

Core Web Vitals Optimization

We evaluate key experience metrics such as loading performance, interaction responsiveness, and visual stability.

Structured Data Review

We check schema markup for technical validity and relevance to the page content.

Mobile SEO Review

We review mobile usability, responsive layouts, and technical issues that may affect mobile search performance.

Crawlability and Indexability

Search engines cannot rank pages they cannot properly access or index.

Common crawl and indexing problems include:

  • Important pages blocked by robots.txt
  • Incorrect noindex tags
  • Broken internal links
  • Duplicate URLs
  • Poor navigation
  • Incorrect canonical tags
  • Redirect loops
  • Orphan pages
  • JavaScript-dependent content
  • Weak internal linking

Our technical SEO services help identify and resolve these issues so important pages are easier to discover and understand.

Robots.txt and Meta Robots Optimization

Robots directives control how search engines interact with certain areas of your site.

Incorrect configuration can cause major SEO problems.

For example:

  • Blocking important pages
  • Allowing low-value pages to be crawled excessively
  • Applying noindex to pages that should rank
  • Creating conflicts between robots.txt and meta robots

We review these settings carefully to make sure they align with your SEO goals.

XML Sitemap Optimization

An XML sitemap helps search engines discover important URLs.

A well-maintained sitemap should generally include:

  • Canonical pages
  • Indexable URLs
  • Important content
  • Current live pages

It should avoid:

  • Redirected URLs
  • Error pages
  • Duplicate URLs
  • Noindex pages

Keeping the sitemap clean can make crawling and indexing more efficient.

Canonicalization and Duplicate Content

Duplicate or near-duplicate URLs can make it harder for search engines to determine which version should be treated as the primary page.

We review:

  • Canonical tags
  • URL parameters
  • HTTP vs HTTPS
  • WWW vs non-WWW
  • Trailing slash variations
  • Duplicate product or category URLs
  • Print or filtered versions

Proper canonicalization helps consolidate signals and reduce unnecessary duplication.

Redirects and Status Codes

HTTP status codes tell search engines what has happened to a URL.

Important examples include:

  • 200: Page is available
  • 301: Page has permanently moved
  • 302: Temporary redirect
  • 404: Page not found
  • 410: Page intentionally removed

We review redirect logic to reduce:

  • Chains
  • Loops
  • Broken destinations
  • Incorrect status codes
  • Lost link equity

Clean redirect handling is especially important during website migrations and redesigns.

404 and Soft 404 Issues

A normal 404 tells search engines that a page does not exist.

A soft 404 occurs when a page appears missing or useless but still returns a successful status code such as 200.

Soft 404s can create confusion for search engines and waste crawl activity.

We identify and correct these issues as part of a website SEO audit.

Website Architecture Optimization

A clear website structure helps both users and search engines understand how pages relate to one another.

Strong architecture may follow a logical structure such as:

Homepage → Service Category → Individual Service → Supporting Content

We review:

  • Navigation depth
  • Folder structure
  • Internal links
  • Orphan pages
  • Page hierarchy
  • Breadcrumbs

Important pages should not be buried unnecessarily deep within the site.

Internal Linking for Technical SEO

Internal links help search engines discover pages and understand relationships between topics.

We identify opportunities to improve:

  • Service-to-service links
  • Blog-to-service links
  • Category relationships
  • Breadcrumbs
  • Orphan pages
  • Anchor relevance

Good internal linking also helps users move through the website more easily.

Core Web Vitals Optimization

Page experience can be affected by how quickly and smoothly a site loads and responds.

We review areas related to Core Web Vitals, including:

  • Largest Contentful Paint
  • Interaction responsiveness
  • Layout stability

Common causes of poor performance may include:

  • Large images
  • Excessive JavaScript
  • Third-party scripts
  • Slow server response
  • Unoptimized fonts
  • Layout shifts
  • Heavy plugins

Improving these areas can support both usability and overall site quality.

Core Web Vitals and website technical performance

Page Speed Optimization

Fast websites create better experiences and reduce unnecessary friction.

Our technical review may consider:

  • Image compression
  • Lazy loading
  • Caching
  • File minification
  • Script management
  • CDN usage
  • Server response
  • Hosting environment

Not every optimization has the same impact, so fixes should be prioritized based on the actual bottlenecks.

Mobile Technical SEO

Search visibility and user experience both depend heavily on mobile performance.

We review mobile issues such as:

  • Viewport configuration
  • Responsive layouts
  • Small buttons
  • Overlapping content
  • Unreadable text
  • Mobile navigation
  • Page speed
  • Content differences between desktop and mobile

Important content and functionality should remain accessible across devices.

JavaScript SEO

Some modern websites rely heavily on JavaScript to display important content.

This can create challenges if content or links are not easily accessible to search engines.

We may review:

  • Client-side rendering
  • Internal links generated with JavaScript
  • Content visibility
  • Lazy-loaded content
  • Navigation
  • Rendered HTML
  • API-driven content

The goal is to make sure important information can still be discovered and processed reliably.

Structured Data and Schema Markup

Structured data can help search engines better understand certain types of page information.

Depending on the website, relevant schema may include:

  • Organization
  • LocalBusiness
  • Service
  • Product
  • BreadcrumbList
  • Article
  • FAQPage

We review structured data for validity and alignment with actual page content.

HTTPS and Website Security

A secure website is an important technical foundation.

We review issues such as:

  • HTTPS implementation
  • Mixed content
  • Incorrect redirects
  • Duplicate HTTP and HTTPS versions
  • Certificate-related problems

Security issues should be addressed before they create trust or accessibility problems.

Technical SEO for Ecommerce Websites

Ecommerce sites often create complex technical SEO challenges due to large catalogs and dynamic URLs.

We may review:

  • Product URLs
  • Collection pages
  • Faceted navigation
  • Filters
  • Pagination
  • Duplicate products
  • Out-of-stock pages
  • Internal linking
  • Canonicals
  • Product schema

The objective is to reduce crawl waste while making important products and categories easier to discover.

Technical SEO for Website Migrations

Website migrations require careful planning.

Changing domains, platforms, URLs, or site structure without proper SEO preparation can affect organic performance.

Our migration planning may include:

  • URL mapping
  • Redirect planning
  • Sitemap updates
  • Canonical review
  • Internal link updates
  • Analytics checks
  • Search Console checks
  • Post-launch monitoring

The goal is to reduce avoidable visibility loss during the transition.

Technical SEO and AI Search

AI-powered search systems still depend on accessible, understandable, and well-structured web content.

Strong technical SEO can support AI search visibility by helping ensure:

  • Important pages are crawlable
  • Content is indexable
  • Structured information is accessible
  • Entities are clearly connected
  • Content hierarchy is understandable
  • Canonical pages are easy to identify

Technical SEO remains an important foundation for both traditional search and newer AI-driven discovery experiences.
