Technical SEO Services to Help Search Engines Crawl, Index and Understand Your Website

Technical SEO Audit Services

A technical SEO audit assesses the parts of your website that can affect crawling, rendering, indexation and search visibility. We examine relevant technical signals, identify recurring issues across templates, and prioritise findings by likely impact, affected pages and implementation effort.

Depending on your website, the audit may cover HTTP status codes, redirect chains, broken internal links, canonical tags, indexation directives, XML sitemaps, robots.txt, JavaScript rendering, internal linking, structured data and Core Web Vitals. The output is a prioritised action plan with examples and recommended next steps.

Crawlability and Indexation Optimisation

Search engines need to discover and access the URLs that matter. We review crawl paths, internal links, robots.txt rules, meta robots directives, HTTP responses and other signals that may prevent important pages from being processed as intended.

We also compare intended indexable pages with available Google Search Console data to investigate unexpected exclusions, duplicate URL patterns and indexing inconsistencies. Indexing decisions remain with Google, so recommendations focus on removing avoidable technical barriers and improving the signals your website provides.

XML Sitemap and Robots.txt Review

An XML sitemap should help search engines discover canonical URLs that are intended to be indexed. We check sitemap accessibility, status codes, URL consistency and whether submitted URLs align with the website's canonical and indexability signals.

We review robots.txt rules to identify unintended crawl restrictions and potential conflicts with the site's intended search visibility. Robots.txt controls crawling; it is not a reliable way to keep a URL out of Google's index. Changes are recommended carefully to avoid blocking resources or sections that search engines need to access.

Canonical Tags, Duplicate URLs and Redirects

Multiple URLs can expose the same or very similar content, while conflicting canonical signals and unnecessary redirect chains can complicate search engine interpretation. We review canonical tags, URL variations, redirect status codes, redirect loops and internal links pointing to redirected or non-canonical URLs.

Recommendations aim to consolidate signals where appropriate, preserve useful URLs and direct users and crawlers to the correct destination. Redirect and canonical changes are planned with care, especially for ecommerce filters, parameter URLs, migrations and large websites.

Website Architecture and Internal Linking

A clear website structure helps visitors navigate and helps search engines discover the relationship between pages. We assess navigation, URL structure, click depth, internal link coverage, orphan-page risks and the pathways leading to key service, category and product pages.

We recommend practical changes that make important pages easier to discover and connect related content logically. Internal links should use descriptive, natural anchor text and support real user journeys rather than repeat exact-match keywords unnecessarily.

Core Web Vitals and Website Performance

Slow or unstable pages can frustrate users and reduce the effectiveness of your website. We assess relevant performance signals and investigate causes such as oversized images, render-blocking resources, JavaScript execution, server response times and layout shifts.

Where data is available, we use field data alongside diagnostic tests to understand real-user performance. Core Web Vitals currently focus on Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS). Improvements are prioritised by user impact and technical feasibility; a perfect tool score is not a substitute for a fast, usable experience.

JavaScript SEO and Rendering

JavaScript frameworks and client-side rendering can affect how content, links and metadata become available to search engines. We review whether important content and navigation elements are discoverable in rendered output and identify potential rendering, resource-access or internal-link issues.

Recommendations depend on the site's framework and implementation. They may include rendering adjustments, server-side rendering or prerendering considerations, and validation of important templates after deployment.

Structured Data and Schema Markup

Structured data can help search engines interpret eligible information on a page. We review existing markup for syntax, consistency with visible content, appropriate schema types and avoidable validation issues.

Where relevant, we recommend or help implement suitable structured data, such as Organization, WebSite, BreadcrumbList, Product or other types that accurately describe the page. Structured data does not guarantee rich results or higher rankings, and markup must follow applicable search engine guidelines.

Mobile Technical SEO

We review whether important content, links, metadata and structured data remain accessible and consistent on mobile devices. Checks may include responsive layout behaviour, mobile rendering, intrusive interface elements, tap-target usability and performance issues that affect key templates.

The objective is to ensure that mobile users can access the same essential information and complete important actions without unnecessary friction.

Website Migration and Technical Change Support

Website redesigns, CMS changes, domain moves and URL restructuring can affect organic visibility if search signals are not handled carefully. Depending on project scope, we can help plan URL mapping, redirects, canonical updates, sitemap changes, internal-link updates and post-launch validation.

For significant migrations, technical SEO should be involved before launch—not only after traffic changes. A documented pre-launch checklist and post-launch monitoring plan can help identify issues early.
