Technical SEO services that solve the problems holding your website back
Most websites don’t struggle because they simply lack content. They struggle because search engines can’t efficiently discover or essentially ‘understand’ the pages that matter most.
Technical SEO focuses on the infrastructure behind your website. It’s not glamorous, but the process of identifying and resolving the issues that prevent search engines from crawling, rendering and indexing your content effectively, is what improves the overall experience (and conversion rate) for your users.
Our technical SEO consultants combine specialist auditing tools with years of hands-on experience to identify opportunities that deliver actionable improvements. From Core Web Vitals and internal linking to structured data, JavaScript rendering and website migrations, we provide practical and prioritised recommendations that support the overall website objective.
Whether you need a one-off technical SEO audit or ongoing consultancy as part of a wider SEO strategy, our team works alongside yours to ensure every technical improvement contributes towards the wider business goals.

Technical SEO problems we solve
Technical SEO issues aren’t always obvious. Your website might look and function perfectly from a user’s perspective while search engines struggle to crawl, understand or prioritise your content effectively. Technical barriers can quietly limit performance long before they become visible in reporting.
Organic traffic has plateaued
Sometimes rankings don’t decline – they simply stop improving.
As websites grow, technical debt accumulates. Duplicate pages, inefficient internal linking, outdated redirects and increasingly complex site structures can make it harder for search engines to understand which pages deserve the most visibility.
A technical SEO audit helps uncover these hidden barriers, allowing us to prioritise improvements that support sustainable organic growth.
Important pages aren't being indexed
Creating valuable content is only worthwhile if search engines can discover and index it.
We investigate why important pages may be excluded from Google’s index, whether that’s caused by crawl directives, duplicate content, poor internal linking, rendering issues or technical configuration errors.
Our goal is to ensure your most valuable pages are visible, accessible and eligible to rank.
Your website is slow
Website performance influences far more than user experience.
Slow-loading pages can increase bounce rates, reduce conversions and make it harder for search engines to efficiently crawl your website.
We assess performance across desktop and mobile devices, identifying opportunities to improve Core Web Vitals, reduce unnecessary page weight and deliver faster, more reliable experiences for your users.
Rankings dropped after a website migration
Website migrations are one of the highest-risk moments for organic visibility.
Changes to URLs, navigation, content or platform architecture can unintentionally remove years of accumulated SEO value if they’re not carefully managed.
Whether you’re moving to a new CMS, redesigning your website or consolidating multiple domains, we provide technical SEO support before, during and after launch to help preserve rankings and minimise disruption.
Our Technical SEO Process
Every website presents a different set of technical challenges. That’s why we don’t rely on generic checklists or automated reports alone. Our technical SEO consultants combine specialist tools with hands-on analysis to understand how your website performs today, what’s limiting its visibility and which improvements will have the greatest commercial impact.
Whether we’re supporting a one-off technical SEO audit or acting as an extension of your internal marketing team, our process is designed to deliver clear priorities, practical recommendations and measurable improvements.
-
1. Discovery & Understanding
Every project begins by understanding your business, your website and your objectives.
We take time to understand how your website has evolved, the technologies it relies on and the challenges you’re currently facing. Whether you’ve experienced a drop in rankings, are preparing for a website migration or simply want to build stronger technical foundations, understanding the wider context allows us to focus our efforts where they’ll have the greatest impact.
This stage often includes reviewing your existing SEO strategy, analytics, Search Console data and previous technical work to build a complete picture of your website’s current performance.
-
2. Comprehensive Technical Audit
Once we understand your objectives, we carry out a detailed technical audit of your website.
Using a combination of industry-leading auditing tools and manual analysis, we assess the factors that influence how search engines crawl, render and index your content. Rather than generating hundreds of disconnected recommendations, we focus on identifying the issues that genuinely affect search visibility and user experience.
Every finding is categorised by priority, allowing your team to quickly understand what should be addressed immediately, what can be planned for future development and which areas are already performing well.
-
3. Prioritisation & Technical Roadmap
Not every technical issue deserves immediate attention.
Some recommendations can deliver significant improvements with minimal development effort, while others require careful planning alongside wider business objectives. We work with your stakeholders to create a prioritised roadmap that balances SEO opportunity against available resources.
This ensures development time is invested where it delivers the greatest return, rather than simply working through a lengthy list of recommendations in order.
-
4. Implementation Support
Making recommendations is only part of the process.
Whether your website is managed by an internal development team or an external agency, we provide clear implementation guidance that removes ambiguity and speeds up delivery.
Where required, we work directly alongside developers to explain technical recommendations, validate completed work and ensure changes have been implemented correctly. This collaborative approach helps avoid common implementation mistakes that can undermine otherwise well-planned SEO improvements.
-
5. Validation & Quality Assurance
Technical SEO doesn’t end when changes go live.
Every implementation is reviewed to confirm it behaves exactly as expected. We validate crawlability, indexing, redirects, structured data, internal linking and performance improvements to ensure recommendations have delivered the intended outcome.
Where additional refinements are required, we’ll identify them early before they have an opportunity to affect search performance.
-
6. Ongoing Monitoring & Continuous Improvement
Search engines evolve, websites change and new technical challenges emerge over time.
That’s why technical SEO should be viewed as an ongoing process rather than a one-off exercise. We continuously monitor your website’s technical health, identify new opportunities and adapt our recommendations as Google’s algorithms, user behaviour and your own website continue to evolve.
By continually improving your website’s technical foundations, we help create a platform capable of supporting sustainable organic growth for years to come.
Why businesses choose First Internet for technical SEO
Technical SEO isn’t about generating long lists of recommendations. It’s about understanding which issues genuinely matter, how they affect your business and what should be prioritised first.
Our consultants combine technical expertise with commercial thinking, helping businesses focus on improvements that support measurable growth rather than chasing low-impact optimisation tasks.
Whether we’re supporting an in-house marketing team, collaborating directly with developers or delivering ongoing consultancy as part of a wider SEO strategy, our approach remains the same: identify the barriers, explain the opportunity and implement practical solutions that make a measurable difference.
Questions about technical SEO?
-
What is technical SEO?
Technical SEO is the process of improving the underlying structure of a website so search engines can crawl, understand and index its content more effectively. It covers areas such as website architecture, page speed, structured data, internal linking, Core Web Vitals, XML sitemaps, redirects and much more. A technically sound website creates a stronger foundation for every other aspect of SEO.
-
Why is technical SEO important?
Even the best content struggles to perform if search engines can’t efficiently discover or understand it.
Technical SEO removes barriers that limit organic visibility, helping search engines prioritise your most valuable pages while improving user experience, website performance and long-term search visibility.
-
How long should a tech SEO audit take?
In the agency world, a good technical audit should take 1 to 2 days. This comprises of a thorough, multi-point checklist of checks that run through all the most important aspects of website health. Our comprehensive technical SEO audit is constantly reviewed to ensure we’re checking against the latest developments in the world of SEO.
-
What is the difference between technical and ‘normal’ SEO?
You can think of technical SEO as the roots of a tree – the vibrant colours and size of the tree itself will capture most attention, but the roots are what allows the tree to grow. Tech SEO is less glamorous, simply because it’s not as visible. It comprises of a lot of background activity that props a website up, whilst other parts of SEO take care of copywriting, headlines, targeting and overall user experience.
-
Can technical SEO improve rankings?
Technical SEO doesn’t guarantee higher rankings on its own, but it provides the foundation that allows other SEO activity to perform more effectively.
Removing technical barriers makes it easier for search engines to crawl and understand your website, helping your content compete more effectively within search results.
-
Do you offer technical SEO as a standalone service?
Absolutely. Many businesses choose a standalone technical SEO audit to benchmark their website before deciding on their next steps. Others retain our consultants on an ongoing basis to support website development, monitor technical health and provide specialist guidance as their website evolves.
-
Do you work alongside in-house development teams?
Yes. Many of our clients already have internal developers or external web development partners.
We provide clear technical recommendations, collaborate throughout implementation and validate completed work to ensure changes have been applied correctly.
-
What Technical SEO issues are the most important?
Various technical issues can present themselves at different levels of severity, based on the status of your website. But most commonly, issues with broken links or hidden pages are ultimately going to have the biggest impact for most situations. Pages that can’t be accessed properly are never going to rank, which is not the situation you want to be in! Other problems such as slow page speed and non-sensical site structure will also be damaging to your SEO progress and overall visibility.
