Search expertise from the technology partner trusted by UK businesses.
Why partner with us

With Zenzero, your technical SEO is handled by a team that already manages the infrastructure websites run on.

Many technical SEO problems sit below the content: slow server response times, redirect chains left behind by a migration, pages blocked from crawling, or a CMS setting that tells Google to ignore a whole section of your site.

A typical SEO agency can find these issues but often must pass them to a developer or hosting provider to fix. Zenzero has supported the IT infrastructure of UK businesses for more than 20 years, so we can diagnose and fix problems at the server, hosting and CMS level as well as on the page.

Changes are tested and deployed under the same change control we use for our managed IT clients, so work to improve your search performance never puts your live website at risk.

Partnership

How can Zenzero help?

When your website is a key source of leads, you need to know it is working as hard as it can. We deliver thorough Technical SEO services that combine crawl data, Google Search Console performance data, and competitor analysis to show exactly where your site stands and why.

We prioritise technical SEO improvements based on their impact, giving your internal team, your developers or our own specialists clear actions to improve crawlability, indexation and site performance.

What's Included

What does our Technical SEO include?

Crawlability and indexation

If Google cannot find your pages, they do not exist. We assess how efficiently search engines can access and index your most important pages, identifying issues such as blocked content, crawl errors, incorrect redirects and unnecessary pages competing for attention.

CMS Configuration

Your content management system can influence how search engines access and interpret your website. We review its SEO configuration, including URL settings, metadata controls, canonical tags, redirects, sitemaps and indexing rules, to ensure it supports your search strategy.

Site architecture and internal linking

We review your website architecture and internal links to help users and search engines navigate your content, understand the relationship between pages and recognise which pages are most important.

Page Speed Optimisation

Page speed affects both search performance and user experience. We assess your Core Web Vitals, including Largest Contentful Paint, Interaction to Next Paint and Cumulative Layout Shift, to understand how quickly and smoothly your pages perform. We then identify and address issues such as oversized images, inefficient code, slow server response times, render-blocking resources and incorrect lazy loading.

Mobile Optimisation

As Google primarily uses the mobile version of your website for indexing and ranking, a poor mobile experience can limit your search performance. We test your site across different screen sizes and address issues with layouts, tap targets, font sizes and responsive design to create a smoother mobile experience.

Log File Analysis

Log file analysis shows how search engine crawlers interact with your website. We use this data to identify crawl inefficiencies, overlooked pages, wasted crawl activity and technical barriers that may be preventing important content from being discovered or revisited.

JavaScript Rendering and Headless SEO

JavaScript-heavy and headless websites can create additional challenges for crawling, rendering and indexation. We assess how search engines access and process your content, then guide rendering methods, metadata and technical configuration to help important pages remain discoverable.

Schema Markup and Structured Data

We implement and validate relevant schema markup to help search engines interpret your content more accurately. This can improve how your pages are presented in search results and support enhanced features such as ratings, breadcrumbs and business information.

Site security

Your website is a business asset, and it needs the same protection as the rest of your systems. We use the same expertise we apply to helping organisations secure and recover their most valuable data, and turn it to your website. Alongside checks on SSL, HTTPS and mixed content, we find vulnerable plugins and themes, exposed login pages, missing security headers and loose admin access, then close those gaps before they put your site or its rankings at risk.

Site Migration Audits

Website migrations can put existing rankings and traffic at risk if they are not carefully managed. We review your site before, during and after migration, covering redirects, URL changes, crawling, indexation and content mapping to help identify issues that could affect organic performance.

A prioritised action plan

Every finding is ranked by its likely impact and the effort needed to fix it. You get a clear plan that your developers, your content team or our specialists can act on straight away, with the highest value fixes first.

Still have Qs?

Questions we
often get asked:

How do I know if Technical SEO is affecting my rankings?

Common signs include declining organic traffic, pages not appearing in search results, slow page performance, indexing issues, or rankings that fail to improve despite ongoing content creation. There could also be more subtle hints such as

Is Technical SEO a one-off project?

Technical SEO is most effective when reviewed regularly. Website updates, platform changes, migrations, and new functionality can all introduce issues that affect performance over time.

Do I need to rebuild my website for Technical SEO?

In most cases, no. Technical SEO issues can usually be resolved within your existing website or platform. If we identify a limitation that genuinely requires a rebuild, we’ll explain why and recommend the best way forward, but this is rarely necessary.

Can you work with my existing developer?

Absolutely. We regularly collaborate with in-house developers and third-party agencies, providing clear, developer-ready specifications for each recommended fix. We can also work with our own specialists if you need support implementing the changes.

Can technical changes damage my website?

Done carelessly, yes. A wrong redirect or robots setting can remove pages from Google within days. That is why we test changes before deployment and follow a documented change process, the same care we use for the IT systems we manage for clients.
