What technical SEO services UK clients need

Technical SEO is the part of SEO your customers never see. It makes sure Google can reach every important page, load it quickly and understand what it is about. Our technical SEO services UK work focuses on the problems that actually hold small sites back, not on chasing a perfect score in a tool.

The 7 things we fix most often

  1. Pages missing from Google. Blocked by settings, left out of the sitemap, or marked “noindex” by mistake.
  2. Slow mobile loading. Large images, too many plugins, no caching.
  3. Duplicate pages. The same content at several addresses, splitting your rankings.
  4. Broken links and redirect chains. Dead ends for visitors and for Google.
  5. Messy site structure. Important pages buried four clicks deep.
  6. Missing structured data. Schema that tells Google your business type, services and FAQs.
  7. Demo pages and junk URLs. Leftovers from themes that dilute your site.

Between them, these seven account for most of the technical SEO services UK small businesses need.

More detail

Speed and Core Web Vitals

Google measures how fast and stable your pages feel on a phone. These measures are called Core Web Vitals. Google explains them on web.dev. On WordPress sites the fixes are usually caching, image compression and removing heavy plugins. If speed is your main problem, see our WordPress speed optimisation service.

Speed is one of the most visible results of technical SEO services UK clients notice.

Crawlability and indexation

Search engines use crawlers (Googlebot for Google) to discover pages by following links and reading sitemaps. Indexation is whether a page is then stored and eligible to appear in results. We use Google Search Console’s page indexing and URL Inspection reports to see exactly which pages are in, which are out and why.

XML sitemaps and robots.txt

Your XML sitemap should list only the pages you want found. Your robots.txt file should block only what genuinely should not be crawled. On WordPress, Rank Math or a similar plugin manages both, but they still need checking after updates.

Canonical tags and duplicate content

A canonical tag tells Google which version of a page is the main one. We fix duplicates caused by tracking parameters, “www” and non-“www” versions, trailing slashes, and tag or category archives.

Redirects and site migrations

When pages move, 301 redirects pass visitors and most of the ranking value to the new address. We clean up redirect chains and loops, and plan redirect maps before redesigns so rankings are protected.

Site architecture and internal linking

Important pages should be no more than a few clicks from the homepage and linked from related pages with descriptive anchor text. We build simple, logical structures: service hubs, supporting guides and clear navigation.

Rendering and JavaScript

Some content only appears after JavaScript runs. Google can render it, but not always quickly or completely. We check that your key content and links are visible to Google without relying on scripts.

Structured data and entities

Schema markup from schema.org describes your business, services, reviews policy and FAQs in a format machines understand. It helps Google connect your website to your business as an entity, and supports rich results where eligible.

Mobile-first indexing

Google mainly uses the mobile version of your site for indexing and ranking. Content, links and structured data must be the same on mobile as on desktop.

HTTPS and security

Every page should load over HTTPS with a valid SSL certificate and no mixed content. Hacked or spammy pages are found and removed.

International and local foundations

For UK businesses we set the page language to British English (en-GB) and, where needed, hreflang tags. For local firms we add LocalBusiness schema and make sure contact details match the Google Business Profile.

Metric What it measures Good score
Largest Contentful Paint (LCP) How quickly the main content appears. 2.5 seconds or less
Interaction to Next Paint (INP) How quickly the page responds to taps and clicks. 200 ms or less
Cumulative Layout Shift (CLS) How much the page shifts while loading. 0.1 or less

Thresholds from Google’s Web Vitals guidance. We check real-user data in Search Console first, because lab scores in PageSpeed Insights can differ from what visitors experience. Speed problems on WordPress are fixed through our WordPress speed optimisation service.

  1. Baseline. Crawl the site, export Search Console data and record current indexing and speed.
  2. Diagnose. Find the cause of each problem, not just the symptom. A missing page is often a redirect rule, a plugin setting or a template issue.
  3. Fix. Make the change on a staging copy where possible, then on the live site.
  4. Validate. Re-crawl, request indexing in Search Console and confirm the fix worked.

The validate step matters: a fix is not finished until Google has re-crawled the page and the report shows it.

Redesigns are where most small businesses lose rankings. Before any move, our technical SEO services UK clients get:

  • a full list of current URLs and which ones bring traffic and links;
  • a redirect map from every old address to the best new one;
  • checks on the new site before launch: titles, canonicals, noindex tags left on by mistake, and sitemap;
  • monitoring for four to six weeks after launch, so problems are caught early.

Migration planning is included in our technical SEO services UK work whenever a redesign is on the way.

Google’s AI Overviews and assistants such as ChatGPT rely on the same foundations: pages that can be crawled, clear structure, fast loading and accurate structured data. Technical SEO does not guarantee inclusion in AI answers, but a site that search engines struggle to read is unlikely to be used.

Technical work is included in both of our SEO packages. In the first month we fix the urgent issues. After that we check the site every month, because new pages, plugin updates and theme changes break things more often than people expect.

Just want to know what is wrong first? Our fixed-price SEO audit covers all of the above and gives you a written fix list for £199.

  • A list of what we fixed, with before and after where it helps.
  • Any new problems found and when they will be fixed.
  • Pages added to or dropped from Google’s index.
  • Mobile speed scores for your key pages.

Clear reporting is the part of technical SEO services UK businesses tell us they missed most with previous providers.

Ask for a sample report before choosing technical SEO services UK providers.

Some questions come up on almost every call:

  • “Why is my page not on Google?” Usually a setting, a missing sitemap entry or thin content. We check Google Search Console to see exactly why.
  • “Do I need schema?” It helps Google understand your business and can make FAQs and other details eligible for richer results.
  • “Will moving host or rebuilding hurt my rankings?” Not if redirects are handled properly. We map old addresses to new ones before anything moves.

Our technical SEO services UK work is done on WordPress sites every week, so we know where the common problems hide, from plugin conflicts to theme settings that quietly block pages.

Frequently asked questions

What is technical SEO?

It is the work that makes sure search engines can find, load and understand your website: indexing, speed, structure, redirects and structured data.

Usually yes, but less of it. Small sites often have a handful of serious issues that are quick to fix.

The first clean-up is. After that, a monthly check catches new problems caused by updates and new content.

Our main focus is WordPress. Ask us about other platforms and we will tell you honestly if we are the right fit.

Technical work is included in our SEO packages from £449 a month. A one-off check is part of our £199 SEO audit.

Some fixes, such as unblocking pages, can show within days of Google re-crawling. Most improvements show over several weeks.

The first clean-up is a one-off. After that, monthly checks catch new problems caused by updates, new pages and plugin changes.

Only with your permission, and on a staging copy first where possible. Every change is listed in your report.
