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.
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
Crawling: can pages be accessed efficiently?
Crawlers have limited time for each site. Wasted effort on low-value URLs, or blocked access to important ones, can hold a site back.
common problems
- Incorrect robots directives
- Duplicate or low-value URLs
- Parameters that multiply crawlable URLs
Rendering: is content visible as intended?
When content or links depend on JavaScript, search engines may need an extra step to see them. Problems here can leave key content unseen.
common problems
- JavaScript rendering and crawling challenges
- Links that aren't real, crawlable links
- Content that appears only after interaction
Indexing: are the right pages included?
Indexing decisions depend on directives, canonical signals and content quality. Mistakes can keep important pages out, or let unwanted ones in.
common problems
- Important pages not being indexed
- Incorrect canonical tags
- Duplicate or low-value URLs competing with each other
Performance: is the experience good?
Slow, unstable or awkward pages frustrate visitors. Performance is one of several signals, and mainly matters because it affects real people.
common problems
- Slow pages and poor user experience
- Layout shifts and delayed interaction
- Mobile usability issues
Change: what happens when the site changes?
Redesigns, platform moves and URL changes are high-risk moments. Without a plan, old URLs can be lost and visibility can drop.
common problems
- Website migrations that lose URLs or traffic
- Missing or incorrect redirects
- Canonical and sitemap signals left outdated

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.
noindexImportant pages marked noindex
The page asks to be left out of the index, often left over from development.
canonical → wrong URLCanonical tags pointing elsewhere
Signals can consolidate toward the wrong page, or confuse which version to show.
301 → 301 → 200Redirect chains or loops
Extra hops waste crawling and slow visitors; loops can make pages unreachable.
404 from internal linkBroken internal links
Visitors and crawlers hit dead ends, and link paths to other pages are cut.
0 internal linksOrphan pages
Pages with few or no internal links are hard to discover and signal little importance.
sitemap ≠ live URLsInaccurate 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 JSJavaScript-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 · CLSPoor Core Web Vitals measurements
Slow loading, delayed responses or layout shifts can frustrate real visitors.
hreflang mismatchIncorrect hreflang on international sites
Wrong or non-reciprocal annotations can send people to the wrong language or region.
markup ≠ pageBroken 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 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.

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.
