Technical SEO Services That Build a Stronger Search Foundation
Technical SEO services focus on the technical elements that help search engines crawl, understand, access and index your website effectively.
A website can have excellent content and still struggle in search when technical problems get in the way.
Broken links, poor site architecture, incorrect redirects, indexing issues, duplicate URLs, slow pages, JavaScript problems or poorly implemented structured data can all create unnecessary barriers between your website and search engines.
At DigitalHats, we approach technical SEO as a foundation for the wider search strategy — identifying the issues that matter, prioritising them by impact and working with your website infrastructure to create a cleaner, more accessible and search-ready website.
What Is Technical SEO?
Technical SEO is the part of SEO concerned with the technical structure and accessibility of a website.
It helps search engines:
- Discover important pages
- Crawl your website efficiently
- Understand relationships between pages
- Identify the preferred versions of URLs
- Access and render content
- Understand structured information
- Process redirects and status codes correctly
- Index the right pages
- Evaluate the website’s overall page experience
Our Technical SEO Services
Technical SEO is not about adding keywords to a page. It is about making sure the technical foundation does not create avoidable barriers to search visibility.
Technical SEO Audit
We start by understanding how your website is currently performing from a technical search perspective.
Our audit can examine:
- Crawlability
- Indexability
- Site architecture
- Internal linking
- XML sitemaps
- Robots.txt
- Canonical URLs
- Redirects
- HTTP status codes
- Duplicate URLs
- JavaScript rendering
- Mobile usability
- Page performance
- Structured data
- HTTPS and security
- Search Console issues
Rather than treating every technical issue equally, we prioritise findings according to their potential impact and relevance to your website.
Crawlability & Search Engine Access
Search engines need to be able to discover and access the pages that matter.
We identify potential barriers such as:
- Incorrect robots.txt directives
- Unnecessary crawl paths
- Broken internal links
- Poor navigation structures
- Orphaned pages
- Incorrect redirects
- Blocked resources
- Crawl inefficiencies
- Complex URL structures
The goal is to make important content easier for search engines to discover and process.
Indexability & Indexing Issues
Being crawled does not automatically mean a page should be indexed — and not every page on a website needs to be indexed.
We investigate issues involving:
- noindex directives
- Canonicalisation
- Duplicate pages
- Soft 404s
- Incorrect status codes
- Unwanted indexed URLs
- Thin or unnecessary pages
- Indexing inconsistencies
- Sitemap and indexation mismatches
We help ensure that your site’s important pages have the right technical signals to be considered for indexing.
Website Architecture & URL Structure
A logical website structure helps users and search engines understand – how your content is organised.
We evaluate:
- Site hierarchy
- URL structure
- Navigation
- Category structures
- Service-page relationships
- Parent and child pages
- Internal linking
- Content depth
- Orphaned pages
A well-planned architecture can also make it easier to build topical depth and connect related content as your website grows.
Internal Linking
Internal links help connect related pages and provide pathways—through your website.
We review:
- Important pages receiving internal links
- Contextual linking opportunities
- Navigation links
- Anchor text
- Orphaned content
- Deep pages
- Relationships between parent and child pages
The objective is not to add links everywhere.
It is to create a logical network that helps users and search engines navigate your website.
XML Sitemap Optimization
XML sitemaps can help search engines discover URLs on your website.
We review:
- Sitemap availability
- Sitemap structure
- Included URLs
- Canonical consistency
- Indexability of submitted pages
- Sitemap errors
- Large or complex sitemap structures
Where appropriate, we help align your sitemap with the pages you actually want search engines to discover.
Robots.txt Optimization
The robots.txt file provides instructions about which URLs crawlers can request.
Incorrect directives can unintentionally prevent search engines from accessing important resources or pages.
We review robots.txt configurations for:
- Unintended blocking
- Conflicting directives
- Crawl management
- Disallowed resources
- Sitemap references
- Unnecessary rules
Robots.txt should be used carefully. Blocking a URL from crawling is not the same thing as removing it from search results.
Canonicalization & Duplicate Content
Websites can sometimes make the same or substantially similar content accessible through multiple URLs.
This can happen through:
- URL parameters
- Duplicate page paths
- HTTP/HTTPS variations
- WWW/non-WWW versions
- Trailing slash variations
- Ecommerce filters
- Pagination
- CMS-generated URLs
- Tracking parameters
We review canonical signals and URL structures to help search engines understand which version of a page should be treated as the preferred URL.
Redirect & Status Code Management
Website changes often create technical SEO problems when URLs are moved without the right implementation.
We audit:
- 301 redirects
- Redirect chains
- Redirect loops
- 404 errors
- Soft 404s
- 5xx errors
- Incorrect status codes
- Broken internal links
This becomes particularly important during website redesigns, migrations, domain changes and major URL restructuring.
Core Web Vitals & Website Performance
Technical SEO also intersects with the experience users have when visiting your website.
We review performance areas including Google’s Core Web Vitals:
- Largest Contentful Paint (LCP)
- Interaction to Next Paint (INP)
- Cumulative Layout Shift (CLS)
We can also investigate factors such as:
- Heavy scripts
- Large images
- Render-blocking resources
- Unnecessary third-party code
- Server response performance
- Caching
- Page weight
Google recommends good Core Web Vitals as part of providing a good page experience, while also noting that strong scores alone do not guarantee top search rankings.
Mobile SEO & Page Experience
Your website needs to work effectively across devices, particularly mobile.
We review technical and usability considerations such as:
- Mobile rendering
- Responsive layouts
- Content accessibility
- Navigation
- Page speed
- Intrusive elements
- Readability
- Interactive elements
Technical SEO should support both search engine accessibility & a usable experience for real visitors.
JavaScript SEO
Modern websites increasingly depend on JavaScript for navigation, content rendering and interactive functionality.
We investigate situations where JavaScript may affect:
- Content visibility
- Internal links
- Rendering
- Navigation
- Indexability
- Structured data
- Page accessibility
Where necessary, we work with developers to identify technical implementation issues that could affect search engine processing.
Google’s documentation continues to distinguish crawling, rendering and indexing as separate stages, making technical implementation particularly important for JavaScript-heavy websites.
Structured Data Implementation
Structured data provides machine readable information that can help Google understand the content of a page.
Depending on the website and eligible content, this may include structured data for areas such as:
- Organization
- Breadcrumbs
- Articles
- Products
- Local businesses
- Events
- Profiles
- Other supported content types
We review existing structured data, identify relevant opportunities and help implement or correct markup where appropriate.
Structured data can help Google understand page content and may make pages eligible for certain search features – but Google does not guarantee that structured data will result in a rich search appearance.
Our Technical SEO Process
Technical SEO for Website Migrations
A website redesign or migration is not simply a development project.
Changes to URLs, navigation, content, templates or technology can affect how search engines discover and process the website.
Our migration-focused technical SEO work can include:
- Existing URL inventory
- URL mapping
- Redirect planning
- Canonical review
- Internal-link review
- Sitemap updates
- Robots.txt review
- Pre-launch checks
- Post-launch crawling
- Indexing monitoring
- Error monitoring
The objective is to reduce avoidable search visibility disruptions during a major website change.
Technical SEO for Different Website Types
Technical requirements vary depending on the website.
Business Websites
We focus on crawlability, site structure, service pages, internal linking, indexing and performance.
Ecommerce Websites
We pay particular attention to product URLs, categories, filters, parameters, duplicate content, structured data, pagination and large-scale crawling.
WordPress Websites
We investigate CMS-generated URLs, plugins, themes, redirects, sitemaps, schema implementation and performance issues.
Large Websites
Large websites can have more complex crawling and indexing challenges. We look at architecture, internal linking, URL patterns, crawl efficiency and indexation at scale.
Website Migrations
Moving a website can create significant SEO risks if URLs, redirects, canonicals, sitemaps and internal links are not handled properly.
We can help plan and validate the technical SEO side of migrations.
What Technical SEO Can Help Improve
A technically healthier website can provide a stronger foundation for:
Search Engine Crawling
Important pages can be easier for search engines to discover and access.
Indexing
Technical signals can help search engines understand which pages should be considered for indexing.
Website Understanding
Clear architecture, internal links and structured data can help communicate relationships and page meaning.
User Experience
Performance, mobile usability and technical reliability – can contribute to a better experience for visitors.
SEO Scalability
A sound technical foundation makes it easier to expand your website – without accumulating unnecessary technical problems.
Technical SEO is therefore not a replacement for – content, authority or search intent. It supports the wider SEO system.
Technical SEO vs On-Page SEO
These two areas work together but solve different problems.
Technical SEO focuses on how the website is built, accessed, crawled, rendered, indexed & technically understood.
On page SEO focuses more directly on the content and page level elements that communicate relevance to users and search engines.
For example:
Technical SEO:
Can Google access and index this page correctly?
On-page SEO –
Does this page clearly and comprehensively address the searcher’s intent?
A strong SEO strategy needs both.

Frequently Asked Questions
Technical SEO is the process of improving the technical aspects of a website – so search engines can crawl, render, understand and index its important content effectively.
Technical problems can make it harder for search engines – to access or understand a website. Addressing those problems creates a stronger foundation for the site’s “broader SEO strategy.”
Technical SEO can remove technical barriers and improve a website’s search accessibility – but it does not guarantee higher rankings. Search visibility also depends on factors – such as relevance, content quality, competition and other aspects of Google’s systems.
There is no single schedule – that works for every website. A technical audit can be particularly valuable after a – “redesign, migration, major development change or significant traffic/indexing issue.” Larger or frequently changing websites may also benefit from ongoing technical monitoring.
Depending on the project, technical SEO analysis can involve Google Search Console, Google Analytics, crawling tools, PageSpeed Insights, Chrome tools and other specialist SEO and development tools.
Yes. Technical SEO can identify performance problems such as oversized resources, inefficient scripts, server-response issues and other factors that contribute to poor page performance. Implementation may require collaboration with developers.
Yes. Core Web Vitals are commonly included in technical SEO and page-experience assessments. Google’s current Core Web Vitals are LCP, INP and CLS.
Yes. Structured data is commonly considered part of technical SEO because it provides machine-readable information that can help search engines understand page content.
General Questions People Ask About Technical SEO
Technical SEO improves the underlying website infrastructure – so search engines can discover, access, process and understand important content more effectively.
Important areas include “crawlability, indexability, site architecture, internal linking, redirects, canonicalization, mobile accessibility, website performance, structured data & technical reliability.”
Crawling is the process of discovering and accessing URLs. Indexing is the process of analysing and storing information about pages so they can potentially appear in search results. A page being crawled does not automatically mean it will be indexed.
No. Technical health is only one part of SEO. Google can use many signals – when determining which results are relevant and useful for a query. Technical improvements should therefore be treated as a foundation rather than a ranking guarantee.
A technical SEO audit is a systematic review of a website’s technical setup to identify issues that may affect crawling, indexing, rendering, website architecture, performance or search accessibility.
Technical accessibility still matters – because search systems need to discover and process website content. However, technical SEO alone does not determine – whether content will be surfaced in AI-generated search experiences. Content quality, relevance, clarity and other search-system signals remain important.
It can identify technical problems that may contribute to a decline – such as indexing changes, accidental noindex directives, broken redirects, crawl issues or site migrations. However, traffic declines can have many causes – so technical SEO should be investigated alongside content, search demand, competition and broader SEO changes.
Build a Technical Foundation Your SEO Can Rely On
Technical SEO should not be about fixing hundreds of issues simply because a tool has flagged them.
It should be about identifying the problems that matter, fixing them properly and creating a website that is easier for both users and search engines to navigate.
