THE HIDDEN COST OF POOR TECHNICAL SEO

If your website isn’t technically sound, it doesn’t matter how good your content is when it comes to search engine visibility. When pages are slow, crawlers get blocked or indexation is messy, search engines struggle to understand and prioritise your site, which in turns leads to poor visibility, wasted content and a frustrating experience for users – how many times have you left a website because it wouldn’t load!?

Our technical SEO consultants have seen firsthand how a website’s technical elements can limit growth. Common problems like duplicate content, misconfigured tags, slow load times and weak site structure don’t just impact search rankings, they affect how users interact with your site and whether they convert. Over time, this erodes trust, stalls online visibility and damages your ability to scale.

That’s why technical SEO work isn’t just a background task, it’s a core growth lever that is just one part of a wider SEO wider strategy. By auditing and optimising every technical issue, our technical SEO team make your website faster, easier to crawl and ready to scale. The result? A site that ranks better, converts more consistently and delivers long-term results you can build on.

BUILD YOUR SEARCH STRATEGY ON SOLID TECHNICAL FOUNDATIONS

Technical SEO essentially forms the foundation of your website’s organic search performance. We often explain it to clients like this… if your house has poor foundations, it starts to fall down, and the same applies to your website. Without solid technical structure, search engine spiders struggle to crawl, access and interpret your site, no matter how good your content is. Elements like crawl depth, URL structure, internal linking, mobile responsiveness and page speed are all critical to how your site is understood and ranked.

At boxChilli, we take a forensic, tool-led approach to technical SEO. Using tools like Screaming Frog, Lighthouse Metrics and Google Search Console, we audit site architecture, uncover crawl inefficiencies and review internal linking. We also assess sitemap.xml and robots.txt configurations, evaluate JavaScript rendering, and validate structured data, hreflang, canonical tags and other on-site signals. And as search evolves, we also run LLM-focused audits to ensure your site is structured in a way that supports vector-based understanding, helping your content surface in both traditional and AI-driven search results.

Technical SEO isn’t a standalone service, it’s embedded into every SEO strategy we deliver. Our technical SEO specialists work closely with development, content and strategy teams to ensure your website performs at every level. From the first audit to ongoing optimisation, we integrate technical SEO audits into your broader search roadmap to improve visibility, user experience and long-term performance.

  • URL Mapping & Redirects

    We review and restructure your URLs, fix redirect chains and implement clean redirect strategies. This helps maintain link equity, improve navigation and ensure users and search engines reach the correct response code.

  • Schema Markup & Structured Data

Q. What is the difference between technical SEO and on-page SEO?

A.

Technical SEO focuses on how search engines access, crawl and index your website, covering elements like site speed, structured data, sitemaps and server configurations. On-page SEO, on the other hand, is about what appears on the page itself – content, keyword use, headings, internal links and meta data. Both are essential, but technical SEO is the foundation that allows everything else to perform.

Q. Is technical SEO hard?

A.

It can be, particularly on larger or more complex websites, but that’s exactly where a technical SEO consultancy like boxChilli comes in. From working with code and server configurations to understanding how search engines crawl, index and interpret websites, technical SEO requires a specific skill set. Our team simplifies the process, using the right tools and experience to uncover high-impact issues and resolve them in a way that drives lasting results.

Q. Why is technical SEO important?

A.

Without solid technical SEO, even your best content can go unnoticed. You need to ensure search engines have access to crawl and understand your site efficiently, but things like slow load speeds, broken links, messy architecture or indexing issues can get in the way. These problems don’t just hurt visibility, they frustrate users and weaken conversions.

Q. How do technical SEO issues come about?

A.

Most technical issues happen over time – through site updates, plugin conflicts, poor migrations or just a lack of regular maintenance and support. They can also stem from deeper structural problems like bloated code, inconsistent templates or JavaScript rendering errors. Left unresolved, these errors quietly stack up, making it harder to comply with search engine guidelines, ultimately limiting your ability to attract organic traffic.

Q. Do you offer technical SEO as a standalone service?

A.

We do, but more often, it forms part of a wider SEO strategy. Technical SEO is foundational, and when paired with smart content, UX and search-first strategy, that’s when you see real momentum. If you’re just looking to solve specific issues or need support for one-off technical SEO recommendations, we can tailor a package that suits.

Q. What makes your technical SEO process different?

A.

We take a consultative, experience-led approach that goes far beyond templates or tick-box audits. From deep-dive enterprise audits to advanced JavaScript rendering analysis, we uncover and resolve the real issues limiting website performance. Instead of handing over a list of generic recommendations, we take ownership of the fixes ourselves or work directly with your developers to implement them. Every action is prioritised based on commercial impact, ensuring time and resources go where they matter most.

Q. Can you work alongside our developers or in-house SEO team?

A.

Absolutely. We see technical SEO as a collaborative process, not a siloed task. Whether you’re part of an in-house team looking for specialist input or developers needing clear, actionable guidance, we work alongside you to get things done properly. From adapting to your existing tools and workflows to providing annotated task briefs and joining implementation calls, we make sure every fix is accurate, seamless and aligned with your wider goals.

Q. Would you help with technical SEO after a redesign or migration?

A.

Yes, and we strongly recommend it. Site launches, redesigns and platform migrations are common flashpoints for traffic loss, indexation problems and broken user journeys. We support pre- and post-launch technical audits, map redirects, ensure crawlability, preserve rankings and address anything that could impact performance. We’re often brought in specifically for these projects because we know how to keep things running smoothly.

Q. How do you approach technical SEO as part of a wider strategy?

A.

Before we optimise content or build links, we make sure your site’s technical foundation is solid. That’s why our process begins with an in-depth audit of your site’s infrastructure, from crawl paths to code quality. We use that insight to shape a roadmap of technical priorities that support your wider SEO strategy, ensuring every fix pushes you closer to long-term growth.

Q. How do you prioritise technical fixes?

A.

Not every technical issue needs fixing right away. We score each issue based on impact, urgency and effort, then work through them in a way that delivers the biggest gains, fastest. Our technical SEO consultants explain what matters most and why, whether that’s improving crawlability, eliminating duplicate content or speeding up load times. Our goal is to focus on what drives performance and gets your site moving in the right direction.

Q. Will I understand what you’re doing?

A.

We believe you should always understand what’s being done and why. We break down technical issues in a way that’s easy to understand, using plain English, real-world examples and clear actions. Instead of overwhelming you with raw audits or jargon, we take the time to explain what needs fixing, why it matters, and how each change supports your website’s online success.

Q. How do you future proof technical SEO for algorithm changes?

A.

We focus on building technically clean, scalable WordPress websites that align with search engine guidelines and not chasing loopholes or trends. From structured data to crawl efficiency, our fixes are rooted in long-term best practices. We also stay ahead of emerging technologies, including how AI and LLMs process websites, so your technical foundations stay strong even as search engine algorithms evolve.
