Technical SEO Agency Services
We're Koozai, a multi-award winning technical SEO agency that diagnoses and fixes the issues holding your website back from ranking. We've been delivering technical SEO for businesses across the UK since 2006.
What technical SEO actually fixes
Most websites have a gap between the rankings they currently hold and the rankings their content deserves. In the majority of cases, that gap exists not because the content is poor, but because technical barriers are preventing search engines from fully crawling, understanding, and indexing it.
Technical SEO removes those barriers.
The most common issues we find when auditing new clients’ websites are crawl inefficiency (search engines spending budget on the wrong pages), indexation problems (important pages not appearing in search results despite existing), Core Web Vitals failures (pages loading too slowly or generating poor user experience scores), structural issues (poor internal linking, duplicate content, or URL problems), and missing or incorrect structured data (schema markup that could unlock rich results but hasn’t been implemented or is implemented incorrectly).
Any one of these issues can meaningfully suppress rankings. Several working together create a ceiling that no amount of content or link building will break through, because the foundation isn’t solid enough to build on.
Technical SEO is that foundation.
Why choose Koozai as your technical SEO agency?
- We have been doing technical SEO since 2006. That is nearly two decades of algorithm changes, platform updates, Core Web Vitals introductions, JavaScript rendering challenges, and migration projects, across hundreds of websites in dozens of sectors. Our team has encountered and solved the full range of technical SEO problems, including the complex, unusual ones that generic auditing tools don’t flag.
- Our technical SEO team works alongside our broader SEO and content team. Technical SEO in isolation only goes so far. The most effective technical work is informed by keyword data, content strategy, and an understanding of how technical improvements will translate into ranking and traffic outcomes. Our integrated team means technical recommendations are always made in the context of your wider SEO goals.
- We use a proprietary migration framework, the SAFE SEO Migration Method™. Website migrations are one of the highest-risk activities in SEO. Executed poorly, they can destroy years of accumulated rankings in days. Our structured SAFE SEO Migration Method™ reduces migration risk, protects existing rankings, and monitors post-launch performance systematically. This is not a generic checklist, it is a proven methodology developed and refined across dozens of successful migrations.
- We work across sectors and website types. Our technical SEO experience covers ecommerce platforms (Shopify, Magento, WooCommerce), enterprise CMS environments (WordPress, Drupal), JavaScript-heavy frameworks, and bespoke builds. We adapt our approach to the specific technical environment of your website rather than applying a one-size-fits-all methodology.
- Our work is documented and results are attributed. We track technical improvements against ranking and traffic outcomes, not just against a checklist of fixes made. You will always be able to see what changed and what it produced.

Our technical SEO services
At Koozai, our team of technical SEO consultants provides several technical SEO services. These include:
Technical SEO audit
A technical SEO audit is a systematic health check of every element of your website’s technical infrastructure. Identifying the issues preventing your site from performing to its potential and providing prioritised, actionable recommendations to fix them.
Our audits cover crawlability and crawl budget, indexation and noindex management, site architecture and internal linking, page speed and Core Web Vitals, mobile usability, duplicate content and canonicalisation, URL structure and redirect chains, structured data and schema markup, hreflang for international sites, and log file analysis.
Every finding is documented with its likely impact on rankings and a clear prioritised, recommendation for resolution.
Crawlability and indexation
Search engines cannot rank pages they cannot find and index. Crawlability issues: blocked resources, crawl traps, poor internal link equity distribution, or inefficient sitemaps all mean search engines spend their crawl budget on the wrong pages, leaving important content undiscovered. Indexation problems; pages erroneously excluded via noindex, canonical conflicts, or duplicate content mean pages that should appear in search results simply do not. Both categories of issue are common and frequently go undetected without specialist analysis.
We audit crawl behaviour using log file analysis alongside standard crawler tools, giving us insight into what search engines are actually doing on your site, not just what they should theoretically be able to do. We then implement crawl optimisation recommendations and monitor crawl behaviour post-implementation to verify improvement.
Core Web Vitals and page speed Core Web Vitals
Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP) are Google’s user experience metrics and a confirmed ranking signal. Sites that fail Core Web Vitals assessments are at a structural disadvantage in competitive searches. Page speed has been a ranking signal for longer, and is also directly related to conversion rate. A page that loads in under 2 seconds converts at a meaningfully higher rate than one that loads in 5 seconds. The SEO and commercial cases for speed optimisation are aligned. We identify the specific causes of Core Web Vitals failures; whether render-blocking resources, unoptimised images, third-party scripts, or server response time issues, and work with your development team to implement fixes. We measure progress using Google’s field data (Chrome User Experience Report) rather than just lab scores, because field data is what Google uses for ranking decisions.
Structured data and schema markup
Structured data is code added to your pages that helps search engines understand your content more precisely, enabling rich results in SERPs (star ratings, FAQ dropdowns, product information, event listings, and more) and increasingly feeding into AI-generated search responses.
Many websites either have no structured data implemented, have it implemented incorrectly, or are missing schema types that would meaningfully improve their SERP visibility. We audit existing schema, identify missing opportunities, and implement or advise on implementation of the correct schema types for your content; including FAQPage, Product, LocalBusiness, Article, HowTo, and Review schema.
Site architecture and internal linking
How your website is structured, the hierarchy of pages, the depth at which important pages sit, and how link equity flows through internal links, has a significant effect on which pages rank and how competitively they do so.
Common structural issues include important commercial pages buried too deep in the site hierarchy (too many clicks from the homepage), internal link equity concentrated on low-value pages, orphaned pages with no internal links pointing to them, and navigational structures that make it difficult for search engines to understand topical relationships between pages.
We audit your site architecture against your keyword priorities and produce recommendations for restructuring, improved internal linking, and hub-and-spoke content architecture where appropriate.
Technical SEO for website migrations
Website migrations, be that moving to a new domain, replatforming, restructuring URLs, or redesigning the site, are one of the most technically complex and high-risk activities in SEO. Executed without specialist oversight, they frequently result in significant, sometimes permanent, ranking losses.
Our SAFE SEO Migration Method™ is a structured framework that covers pre-migration planning and URL mapping, redirect strategy and implementation, technical configuration of the new environment, Search Console and analytics setup, post-launch monitoring, and rapid response protocols for ranking issues that emerge after go-live.
If you are planning a website migration, even in the early stages, involve us before any decisions are finalised. The most expensive migration problems are the ones that were designed in before the SEO team was consulted. Find out more about our Website Migration SEO service.
Google penalty recovery
If your website has experienced a sudden, unexplained drop in organic rankings or traffic, the cause may be an algorithmic penalty (a ranking adjustment triggered by Google’s core or spam algorithm updates) or a manual action (a penalty applied by a Google reviewer to a specific page or the whole site).
Our team diagnoses the cause of ranking drops, distinguishing between algorithm updates, technical regressions, link profile issues, and manual actions, and builds a recovery strategy appropriate to the specific cause. We have recovered websites from core algorithm penalties, manual actions for unnatural links, and technical issues mistaken for penalties.
On-site technical SEO optimisation
Beyond audit and diagnosis, we implement technical SEO improvements directly, working alongside your development team or handling implementation ourselves where appropriate. This includes:
- Title tag and meta description optimisation across priority pages
- Canonical tag implementation and management
- Hreflang setup and maintenance for international sites
- XML sitemap creation, optimisation, and submission
- Robots.txt configuration
- Redirect mapping and implementation
- Structured data implementation and testing
- Image optimisation for performance and search visibility
- Log file analysis and crawl budget optimisation
Our technical SEO process
1. Discovery and scoping We begin by understanding your website’s history, current performance, technology stack, and the specific concerns or goals that prompted you to seek technical SEO help. This shapes the scope and depth of the initial audit.
2. Technical audit We conduct a comprehensive technical audit using a combination of crawling tools, log file analysis, Google Search Console data, and manual review. The audit is structured around impact: we prioritise findings by their likely effect on rankings and traffic, so the most important fixes are actioned first.
3. Findings presentation We can present audit findings in two formats: a detailed technical document for developers, and/or a clear executive summary for stakeholders. Every finding includes the issue, its likely impact, and a specific recommendation for resolution.
4. Implementation We work with your development team to implement recommendations, or handle implementation ourselves for clients without in-house development resource. We provide precise technical specifications, not vague guidance, so implementations are done correctly first time.
5. Verification and monitoring After implementation, we verify that fixes have been applied correctly and monitor their effect on crawl behaviour, indexation, Core Web Vitals scores, rankings, and traffic.
6. Ongoing technical health monitoring Websites change constantly; new pages are added, templates are modified, third-party scripts are introduced. We provide ongoing technical monitoring to catch and address new issues before they affect rankings.

FAQs
What is Technical SEO?
Technical SEO is all about improving the technical aspects of your website and its content to help it rank more competitively in search engines such as Google. Common technical SEO objectives include actions to make your website faster and easier for search engines to find, render, crawl, understand and index. Content and backlinks will propel your website further in search engines, while technical SEO ensures that the fundamentals on your website are on point. If your website has errors at the most basic level then you will struggle to rank in search engines.
How Critical is Technical SEO When it Comes to Search Marketing?
Technical SEO is one of the most pivotal components of search marketing. It's the mechanism through which search engines like Google access your web pages, analyse content, and determine your placement within search engine results pages (SERPs).
Technical SEO is instrumental in optimising the factors that hold the utmost significance to search engines, thereby maximising your online presence.
What Should I Consider When Selecting a Technical SEO Agency?
When seeking assistance for technical SEO issues, it's essential to engage with a Google Partner agency. This certification ensures adherence to the highest standards of best practices and a profound understanding of the technical prerequisites necessary for achieving optimal Google rankings. Request examples from the agency to showcase how they've assisted other businesses in overcoming technical challenges, providing insights into how they can enhance your online visibility.
What's the Most Important Thing When it Comes to Effective Technical SEO?
Consistency is key. Being on top of potential technical SEO issues is vital. Technology has simplified this process, enabling regular audits to prevent issues from escalating but quality audits still require the human element, to interpret the data and how it impacts your specific business/website. The most effective technical SEO strategies prioritise prevention by addressing minor issues as they arise, and avoiding crisis management when major problems occur.
Do I Need to Conduct a Technical SEO Audit?
Regular technical SEO audits are crucial for maintaining search rankings and preventing potential issues that might impact online visibility. It's advisable to perform multiple audits annually, with quarterly checks being a general guideline. If you've not had one for a while then speak to us about doing an initial SEO audit.
A digital marketing audit with us will identify any issues in your website’s SEO performance and provide you with clear and actionable guidance on what you can do to improve your results. It will also highlight new growth opportunities and how to improve your leads, engagement, user experience, and conversions from search engines.
