Technical SEO Services That Build a Stronger Foundation for Search.

Even useful content can struggle if search engines can't reach, render or understand it. Our technical SEO services improve crawling, indexing, website architecture, performance and technical signals, so your important pages can be discovered and accessed efficiently.

Crawling & indexing Architecture & performance Rendering & structured data
/why-technical-seo-matters

Good content can only perform if search engines can reach it.

If important pages can't be discovered, crawled, rendered or indexed correctly, even excellent content may struggle to gain visibility. Pick a stage to see where problems tend to appear.

Not every technical issue affects rankings equally. The right approach is to identify issues, assess their real impact and prioritise fixes by importance and business goals.

Discovery: can pages be found?

Search engines find pages mainly through links and sitemaps. If those paths are weak or broken, important pages can go unnoticed.

common problems

  • Broken internal links and redirect chains
  • Poor internal linking and website structure
  • XML sitemap problems
/our-technical-seo-services

What our technical SEO services include.

Each service is practical and specific. We prioritise findings by impact rather than handing over a long list of warnings.

Access & indexing

Technical SEO audits

Reviewing your technical setup for issues affecting crawling, indexing, structure, performance and search engine understanding.

Findings are ranked by impact, not just counted

Crawling & indexing optimisation

Checking whether important pages can be discovered and crawled, whether indexing directives are correct and whether content is accessible.

Crawled and indexed are different things

XML sitemap optimisation

Making sure sitemaps are accurate, accessible and consistent with your canonical, indexable URLs.

Sitemaps should aid discovery, not list every URL

Robots.txt & crawl management

Reviewing robots.txt rules and crawl-management considerations, without risking accidental blocking of important content.

Robots.txt controls crawling, not indexing

Canonicalisation & duplicate content

Finding conflicting canonical signals, duplicate URL patterns and parameter issues, and recommending fixes that suit your architecture.

Solutions depend on how your site is built

Structure & performance

Website architecture & internal linking

Improving navigation, URL structure and internal links so people and search engines reach important pages more easily.

Closely related to on-page SEO

Core Web Vitals & page performance

Assessing loading, responsiveness and visual stability, and addressing slow loading, delayed interaction and unexpected layout shifts.

Better scores don't guarantee higher rankings

Mobile SEO & website usability

Reviewing mobile accessibility, responsive behaviour, navigation and content availability.

Helps visitors as much as search

Rendering, markup & markets

JavaScript SEO

Investigating where JavaScript affects content rendering, link discovery or indexing, and keeping important content accessible to search engines.

Rendering can be tested, not assumed

Structured data implementation

Adding suitable markup, such as Organisation, BreadcrumbList, Product or Article, so search engines better understand eligible content.

Must match visible content; rich results aren't guaranteed

International & multilingual technical SEO

Where relevant, setting up language and regional targeting, URL structures and hreflang for sites serving several languages or markets.

Only needed for multi-language or multi-region sites

Change & monitoring

Website migrations & redirects

Support for domain changes, platform moves, URL restructuring, HTTPS transitions and redesigns: redirect mapping, canonical updates, sitemap checks and post-launch monitoring.

Planning before launch matters most

Error monitoring & ongoing improvements

Recurring checks that help detect broken URLs, indexing changes, unexpected redirects and other technical issues over time.

Sites change, so checks should repeat

/common-technical-seo-issues

Common technical SEO issues we investigate.

Examples of what an audit may uncover, and what each could mean. Filter by area.

  • Disallow: /

    Pages blocked from crawling by mistake

    Important sections may never be crawled, so search engines can't see their content.

  • noindex

    Important pages marked noindex

    The page asks to be left out of the index, often left over from development.

  • canonical → wrong URL

    Canonical tags pointing elsewhere

    Signals can consolidate toward the wrong page, or confuse which version to show.

  • 301 → 301 → 200

    Redirect chains or loops

    Extra hops waste crawling and slow visitors; loops can make pages unreachable.

  • 404 from internal link

    Broken internal links

    Visitors and crawlers hit dead ends, and link paths to other pages are cut.

  • 0 internal links

    Orphan pages

    Pages with few or no internal links are hard to discover and signal little importance.

  • sitemap ≠ live URLs

    Inaccurate or outdated XML sitemaps

    Sitemaps listing redirected, removed or non-canonical URLs weaken a useful discovery aid.

  • ?sort=&filter=

    Duplicate URL variations

    Parameters and alternate paths create many near-identical URLs that compete and waste crawling.

  • content after JS

    JavaScript-dependent content not rendered as intended

    Key text or links may not be seen if rendering fails or content loads only on interaction.

  • LCP · INP · CLS

    Poor Core Web Vitals measurements

    Slow loading, delayed responses or layout shifts can frustrate real visitors.

  • hreflang mismatch

    Incorrect hreflang on international sites

    Wrong or non-reciprocal annotations can send people to the wrong language or region.

  • markup ≠ page

    Broken structured data or markup that doesn't match the page

    Errors can prevent eligibility for enhanced results, and mismatched markup can be ignored.

Each issue needs context. A warning from a crawling tool does not automatically mean your site has a ranking problem, which is why we assess impact before recommending a fix.

/technical-seo-by-website-type

Technical priorities differ from site to site.

The right focus depends on how your site is built and what it does. These are illustrative examples, not clients or case studies.

  • Business & corporate websites

/technical-seo-vs-on-page-seo

Technical SEO and on-page SEO do different jobs.

They complement one another, and neither is a substitute for the other.

/choosing-a-technical-seo-agency

What to expect from a technical SEO agency.

Technical work is easy to over-sell. These are the standards worth asking for.

  • Evidence-based recommendations

    Advice grounded in your site's actual condition, not generic checklists.

  • Clear prioritisation

    The issues that matter first, rather than every possible warning.

  • Attention to risk and business impact

    Care that fixes don't harm important pages, and focus on what affects your goals.

  • Explanations for everyone

    Practical detail for developers, and plain language for non-technical stakeholders.

  • Validation after implementation

    Checks that changes work as intended and caused no side effects.

  • Transparent reporting, realistic expectations

    Honest talk about what technical SEO can and can't do on its own.

/technical-seo-faqs

Technical SEO questions, answered plainly.

Not every warning is a ranking factor, and fixes don't promise immediate gains.

Technical SEO is the work of making sure search engines can discover, crawl, render and index your pages efficiently. It covers site structure, crawl access, indexing signals, page performance, structured data and other behind-the-scenes factors.

Typically a technical audit, crawling and indexing review, XML sitemap and robots.txt checks, canonicalisation and duplicate content, architecture and internal linking, performance and Core Web Vitals, JavaScript rendering, structured data, mobile usability, migration support, and ongoing monitoring. The exact scope depends on your site and goals.

It is a structured review of your website's technical setup to identify issues that may affect crawling, indexing, structure, performance and how search engines understand your content. A good audit prioritises findings by impact and explains what to fix first, instead of listing every warning.

Crawling is when a search engine accesses a page. Indexing is when it processes the page and stores it so it can be shown in results. A page can be crawled but not indexed, and a page that is blocked from crawling can sometimes still appear in an index without its content being read.

There are several possible reasons: a noindex directive, canonical tags pointing elsewhere, blocked access, weak internal links, duplicate or low-value content, rendering problems, or simply that the page is new. Checking the page in Google Search Console and reviewing the technical setup helps narrow it down.

Robots.txt tells crawlers which URLs they may or may not request, so it controls crawling. A noindex directive tells search engines not to include a page in their index, so it controls indexing. A noindex tag can only be seen if the page is crawlable, so the two need to be used carefully together.

Core Web Vitals are a set of measurements of real-world user experience: loading performance, responsiveness to interaction and visual stability. They are one of many signals, and improving them mainly benefits visitors. They don't guarantee higher rankings.

Page experience, including speed, can be one of many factors, and slow pages can frustrate visitors and reduce conversions. Speed alone rarely overcomes weak relevance or content, so we treat it as one part of a wider picture.

Sometimes, when technical issues are what is holding a site back. But technical SEO alone won't solve every organic search problem. Content relevance, authority and competition also matter, so we assess the cause before recommending fixes.

It depends on how often your site changes. Many sites benefit from a thorough audit at the start and periodic checks afterwards, with more frequent monitoring for large, fast-changing or ecommerce sites, and before and after redesigns or migrations.

Often some development access is needed to implement fixes, depending on your platform. We can provide clear recommendations for your developers and, where the agreed scope and access allow, implement changes ourselves. Not every issue can be fixed without access to the site's code or settings.

Typically a URL inventory, redirect mapping, canonical and sitemap updates, pre-launch testing and post-launch monitoring for lost URLs, errors and indexing changes. Planning before the move is the most important part, because it helps existing pages and signals carry across.
