Technical SEO

Fix what's holding your site back

Most websites have technical issues that quietly prevent Google from crawling, indexing and ranking their pages properly. These problems don't show up on the surface, but they cost you rankings every single day.

Technical SEO is the process of finding and fixing those issues. It's the foundation that content, links and local signals all depend on. Without it, the rest of your SEO investment works harder than it needs to.

Get a technical SEO audit
Crawlability and indexing If Google can't crawl your pages, they can't rank. We audit your crawl budget, robots.txt, sitemaps and index coverage to make sure every important page gets found.
Core Web Vitals and page speed Google uses real-world speed data as a ranking factor. We identify what's slowing your pages down and fix it, covering everything from image optimisation to render-blocking scripts.
Site structure and architecture A well-structured site helps Google understand your content hierarchy and passes authority to the pages that matter most. We audit and improve your internal linking and URL structure.
HTTPS, security and mobile Security signals, mobile usability and structured data all feed into how Google assesses your site's quality. We check and fix issues across all three.
What's included

What our technical SEO service covers

A thorough technical audit and fix programme covering every element that affects how Google crawls, understands and ranks your site.

Crawl audit We crawl your site the way Google does, identifying orphaned pages, crawl traps, redirect chains and blocked resources that waste crawl budget and hide content.
Index coverage review We check Google Search Console for indexing errors, noindex tags applied in error, and pages that should be ranking but aren't appearing in the index at all.
Core Web Vitals and page speed LCP, INP and CLS measured at field level. We identify the specific elements causing failures and provide concrete fixes, not just a list of scores.
Site architecture and internal linking We audit your URL structure, site depth, internal link distribution and anchor text to ensure PageRank flows to your most important pages.
Redirect audit Redirect chains, loops, and 404s found and fixed. Every unnecessary redirect costs link equity and slows your pages down.
Duplicate content and canonicalisation We identify duplicate and near-duplicate content, incorrect canonical tags, and parameter issues that split ranking signals across multiple URLs.
Schema markup and structured data We audit your existing structured data for errors and implement the schema types that improve your appearance in search results and AI-generated answers.
Mobile usability and HTTPS Mobile-first indexing means your mobile experience is what Google judges. We check usability, viewport configuration, security and mixed content issues.
How it works

From audit to implementation

01

Full technical audit

We run a comprehensive crawl of your site alongside a Google Search Console review, covering crawlability, indexing, speed, structure, schema and security. Every issue is documented with its impact and priority.

02

Prioritised action plan

Not all technical issues are equal. We prioritise fixes by ranking impact and effort, so you know exactly what to tackle first for the fastest gains, and what can wait.

03

Implementation

We fix the issues directly or work alongside your development team with clear, precise instructions. Nothing gets lost in translation between audit and action.

04

Verification and monitoring

Once fixes are in place we verify they've been implemented correctly, check for any new issues introduced, and monitor the impact on rankings and crawl performance over time.

Why it matters

Why technical SEO is the foundation of everything

You can have great content and strong links, but if your technical foundations are broken, none of it works as well as it should. Technical SEO is not optional. It is what makes everything else possible.

Google can only rank what it can find

If pages are blocked, buried too deep in your site or not being crawled, they simply won't appear in search results. Technical SEO makes sure every page worth ranking is discoverable.

Speed is a ranking factor

Google uses Core Web Vitals as part of its ranking algorithm. These are real-world speed metrics. A slow site loses rankings to faster competitors, even if the content is better.

Duplicate content splits your signals

When Google finds multiple versions of the same page, it splits its assessment of authority across them. Canonical tags and proper URL management ensure your signals concentrate on the right pages.

AI search demands clean structure

Generative AI tools rely on structured data and clean site architecture to understand and cite your content. Strong technical foundations directly improve your visibility in AI-generated answers.

Healthy vs broken

What a technically healthy site looks like

Most sites fall somewhere between these two states. The further you sit towards the left column, the more rankings and traffic you are leaving on the table.

Technically broken site
Pages blocked from crawling Important pages blocked in robots.txt or marked noindex by mistake, invisible to Google.
Slow page load times Pages taking 4 seconds or more to load, failing Core Web Vitals and losing rankings to faster competitors.
Duplicate content Multiple URLs serving the same content, splitting ranking signals and confusing Google about which page to rank.
Broken internal links and 404s Dead links wasting crawl budget and creating a poor experience for both users and search engines.
No structured data Google has no machine-readable context about the business, its services or its location.
Poor mobile usability Text too small to read, buttons too close together, content overflowing the viewport on mobile devices.
Technically healthy site
Clean crawl coverage Every important page is crawlable and indexed. Crawl budget is used efficiently with no wasted requests on low-value URLs.
Passing Core Web Vitals Pages load fast in real-world conditions, LCP, INP and CLS all in the green at field data level.
Canonical tags correctly applied One authoritative URL for each piece of content, all link equity consolidated where it needs to be.
Clean internal link structure No broken links, no redirect chains, PageRank flowing efficiently to the most important pages on the site.
Schema markup implemented Structured data giving Google and AI search tools clear, accurate context about the business and its content.
Mobile-first and secure Fully responsive, passing mobile usability checks, served over HTTPS with no mixed content warnings.
Ongoing monitoring

Technical SEO is not a one-time job

A technical audit fixes the issues that exist today. But websites are not static. Every time someone publishes a new page, updates a plugin, changes a URL or deploys a site update, new technical issues can be introduced.

Algorithm updates shift what Google prioritises. New pages create new opportunities for crawl errors. A site that passed its Core Web Vitals check six months ago can quietly start failing after a theme update or a new third-party script is added.

Without ongoing monitoring, problems go unnoticed until they show up as a drop in rankings. By that point, the damage has already been done for weeks or months.

Talk to us about ongoing monitoring
Algorithm updates change the rules Google updates its algorithm hundreds of times per year. What qualified as a technically sound site last year may not meet the same standards today.
Site changes introduce new issues Plugin updates, theme changes, new pages and content migrations all create opportunities for technical problems to appear. Most go unnoticed without active monitoring.
Core Web Vitals drift over time Speed and usability scores degrade as sites grow. New images, scripts and third-party tools add weight. Without regular checks, performance quietly falls below passing thresholds.
We catch problems before they cost rankings Our ongoing technical monitoring identifies new issues as they appear, so they get fixed quickly rather than quietly dragging your visibility down for weeks.
Who it's for

Technical SEO is for any business that depends on organic search

If customers find you through Google, the technical health of your site directly affects how many of them see you. These are the situations where we most commonly see technical SEO making a significant difference.

E-commerce sites

Large product catalogues create crawl budget issues, duplicate content from filters and pagination problems that can invisibly suppress hundreds of product pages from ranking.

Local businesses

Technical issues like missing LocalBusiness schema, slow mobile pages or incorrect canonicalisation directly affect how prominently local businesses appear in map pack and local results.

Professional services

Solicitors, accountants and consultants competing in high-value searches cannot afford to lose ground to competitors because of technical issues that could be fixed in a week.

Content-heavy sites

Blogs, news sites and resource hubs with hundreds of pages are particularly vulnerable to indexing issues, thin content problems and internal link structures that bury their best work.

B2B companies

When organic search is a primary lead generation channel, technical problems that suppress visibility have a direct impact on pipeline. The cost of inaction is measurable.

Sites that have seen a rankings drop

A sudden or gradual decline in organic traffic is often technical in origin. A proper audit identifies whether a crawl issue, an indexing problem or a speed regression is responsible.

Signs your site needs a technical SEO audit

Traffic has dropped without an obvious content or link-related reason

Pages are not in Google's index despite being published and linked to

Your site loads slowly on mobile or fails PageSpeed Insights checks

Google Search Console is showing crawl errors or coverage issues

You have recently migrated your site or changed your URL structure

You have never had a professional technical SEO review done on your site

FAQs

Technical SEO questions, answered

What is technical SEO?
Technical SEO refers to the process of optimising the infrastructure of your website so search engines can crawl, index and rank your pages effectively. It covers areas like site speed, crawlability, indexing, site architecture, structured data, mobile usability and security.
How do I know if my site has technical SEO issues?
Common signs include pages that aren't ranking despite good content, sudden drops in organic traffic, slow page load times, crawl errors in Google Search Console, or thin indexing coverage. A professional technical audit is the most reliable way to identify exactly what's happening.
How long does a technical SEO audit take?
For most small to medium-sized sites, a thorough technical audit takes between one and two weeks. Larger or more complex sites with many pages, subdomains or JavaScript-heavy builds take longer. We agree the timeline and scope with you before starting.
Do you implement the fixes or just provide recommendations?
Both. We can implement fixes directly on your site, or we can work alongside your development team by providing clear, detailed implementation instructions. We are flexible depending on your setup and preferences.
Will fixing technical SEO issues improve my rankings?
In most cases, yes, particularly if there are crawling or indexing issues preventing pages from ranking at all. The impact and timeline depend on the severity of the issues found and how competitive your target keywords are. We give you an honest assessment of expected impact before any work begins.
How is technical SEO different from on-page SEO?
On-page SEO focuses on the content of individual pages: titles, headings, copy and keywords. Technical SEO focuses on the infrastructure of the site, covering how it's built, how fast it loads, how search engines navigate it and how well-structured the data is. Both are necessary for strong rankings.
