Technical SEO: Fix, Rank & Get Found in AI Search

Technical SEO is the work that helps Google, Bing and AI tools find, read and trust your website. If your site is slow, badly structured or blocked from search engines, great content and a good reputation will not save it. You simply will not show up.

I have audited hundreds of UK websites, and the pattern in Liverpool is always the same. A plumber in Wavertree, a law firm in the Commercial District or a restaurant on Bold Street has a site that looks great. But behind the scenes there are broken redirects, pages Google never indexed, and a mobile speed score that sends customers straight to a competitor.

This guide walks you through technical SEO from the basics to advanced checks, in plain English. You can use it as a checklist for your own site, as a brief for your developer, or as a way to judge whether your SEO agency is doing the right work.

What technical SEO actually means

Think of your website as a shop on Church Street. Content is what is on the shelves. Links and reviews are your reputation around town. Technical SEO is the building itself: the front door, the signs, the lighting and the aisles. If the door is locked, nobody comes in, no matter how good the products are.

In practical terms, technical SEO makes sure that:

• Search engine crawlers such as Googlebot and Bingbot can reach your pages
• Google can index the right pages and ignore the wrong ones
• Your pages load fast and work well on mobile phones
• Search engines and AI tools understand what your business is, where it is and what it offers

Why it matters more in Liverpool right now

Liverpool has a busy and growing digital economy, with investment around the Knowledge Quarter, Liverpool Waters and the Baltic Triangle. That means more local businesses are fighting for the same searches, such as “accountant Liverpool” or “emergency electrician near me”.

When two businesses have similar reviews and content, the one with the cleaner, faster, better structured website usually wins. Technical SEO is often the tie breaker in a competitive local market.

Search is also changing. People now ask ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot for recommendations. These tools can only mention businesses whose websites they can read clearly. A technically sound site is now the entry ticket to both Google and AI search.

Level 1: The basics every website must get right

Start here. If these basics are broken, nothing else in this guide will help much.

Step 1: Set up your tools and take a baseline

Before fixing anything, get access to the free tools that show you what search engines see:

• Google Search Console: shows which pages are indexed, what errors Google finds, and which searches bring people to your site
• Bing Webmaster Tools: Bing also powers Microsoft Copilot and feeds some AI tools, so it matters more than most people think
• Google Analytics 4: tracks visitors and enquiries
• Google Business Profile: essential for Google Maps and the local map pack
• A crawler such as Screaming Frog (free up to 500 URLs) or Sitebulb, which scans your site the way Googlebot does

Write down your starting numbers: indexed pages, organic visitors, monthly enquiries and where you rank for your main “service + Liverpool” searches. You cannot prove progress without a baseline.

Step 2: Check that search engines can crawl your site

Crawling is how Googlebot discovers your pages by following links. Check these things:

• robots.txt: visit yourdomain.co.uk/robots.txt. Make sure it does not block important folders, CSS or JavaScript files. One wrong line (Disallow: /) can hide your whole website.
• Status codes: your crawler will list pages returning 404 (not found), 500 (server error) or redirect chains. Fix broken internal links and point old URLs to the right new page with a 301 redirect.
• Crawl depth: important pages should be no more than three clicks from the homepage.
• Orphan pages: pages with no internal links pointing to them are hard for Google to find. Link to them or remove them.

Step 3: Make sure the right pages are indexed

Being crawled does not mean being indexed. Open the Pages report in Google Search Console and look for:

• “Crawled, currently not indexed”: Google saw the page but decided it was not worth keeping. Usually a sign of thin or duplicate content.
• “Discovered, currently not indexed”: Google knows the page exists but has not visited it. Often a sign of weak internal links or a slow server.
• Noindex tags: check that no important page has a noindex tag. This often gets left on after a new site launch from a staging site.
• Canonical tags: each page should point its canonical tag to itself, unless it is a true duplicate. Canonicals should never point to a redirected or broken page.
• Duplicate versions: your site should load on only one version, for example https://www.yourdomain.co.uk. The http, non-www and trailing slash versions should all redirect to it.

Step 4: Clean up your XML sitemap

Your XML sitemap is a list of pages you want Google to index. Submit it in both Google Search Console and Bing Webmaster Tools. It should only include pages that load correctly (status 200), are indexable and are the canonical version. On bigger sites, split it by type: pages, blog posts, services, locations and products.

Step 5: Secure your site with HTTPS

Every page should load on HTTPS with a valid SSL certificate. Check for “mixed content”, where a secure page loads images or scripts over plain http. Browsers show warnings for this, and customers leave. Turn on HSTS so browsers always use the secure version.

Level 2: Site structure and on-page technical SEO

Once Google can reach and index your site, the next job is to make it easy to understand. A clear structure tells search engines which pages matter most.

Site architecture and URLs

Organise your site like a family tree. The homepage sits at the top, main service categories sit below it, and individual services and locations sit below those. For example:

• yourdomain.co.uk/services/
• yourdomain.co.uk/services/boiler-repair/
• yourdomain.co.uk/services/boiler-repair/liverpool/

Keep URLs short, lowercase and separated by hyphens. Use UK spelling such as “optimisation”, “colour” and “centre”, because that is what people in Liverpool type into Google. Add breadcrumbs so both visitors and search engines can see where each page sits.

For online shops, control filter and sorting URLs (such as ?colour=red&size=10). Left alone, they can create thousands of near identical pages that waste Google’s time.

On-page technical elements

• Title tags: unique on every page, around 50 to 60 characters, with the main keyword near the start. Add “Liverpool” where the page targets local searches.
• Meta descriptions: a short, honest summary that makes people want to click. Google may rewrite it, but a good one still helps.
• Headings: one H1 per page, then H2s and H3s in a logical order. Headings help Google and AI tools pick out the key points.
• Images: descriptive file names (boiler-repair-liverpool.webp, not IMG_2231.jpg), useful alt text, and modern formats like WebP or AVIF.
• Thin and duplicate content: pages with only a few lines of text, or many pages saying the same thing, drag the whole site down.

Internal linking

Internal links pass authority from one page to another and show Google what matters. Link from your homepage and popular blog posts to your key service pages. Use descriptive anchor text such as “commercial cleaning in Liverpool” rather than “click here”, but vary it so it reads naturally.

A simple hub and spoke model works well for local businesses: a main Liverpool page links out to each service and area page, and each of those links back to the hub.

Mobile first indexing

Google now looks at the mobile version of your website first. Most local searches in Liverpool happen on a phone, often on the go. Check that:

• The mobile site has the same content, links and structured data as the desktop site
• Buttons are easy to tap and text is readable without zooming
• Your phone number is a click to call link
• Pop-ups and cookie banners do not cover the main content

Level 3: Page speed, Core Web Vitals and JavaScript

Speed is where many Liverpool websites lose customers without knowing it. If a page takes more than a few seconds to load on a phone, people go back to Google and pick the next result.

Core Web Vitals explained simply

Core Web Vitals are three measurements Google uses to judge real user experience:

Metric	What it measures	Good score
Largest Contentful Paint (LCP)	How fast the main content appears	2.5 seconds or less
Interaction to Next Paint (INP)	How quickly the page reacts when someone taps or clicks	200 milliseconds or less
Cumulative Layout Shift (CLS)	How much the page jumps around while loading	0.1 or less

Check them in PageSpeed Insights and the Core Web Vitals report in Google Search Console. Trust the “field data” from real users (the Chrome UX Report) over lab scores from Lighthouse.

How to make your site faster

• Hosting: use a UK based server or a CDN (content delivery network) with servers in London or Manchester, so pages reach Merseyside users quickly
• Images: compress them, use WebP or AVIF, and lazy load images further down the page. Do not lazy load the main hero image.
• Fonts: limit the number of font styles and preload the main one
• Third party scripts: chat widgets, booking tools, review badges and tracking pixels often slow local business sites the most. Remove what you do not use.
• Caching: turn on browser and server caching
• Test like a customer: test on a mid range Android phone over 4G, not just on office broadband

JavaScript SEO

Many modern sites are built with JavaScript frameworks such as React, Next.js or Vue, or with builders like Wix and Shopify. Google can read JavaScript, but it takes more effort and sometimes fails. AI crawlers such as GPTBot often do not run JavaScript at all.

• Use the URL Inspection tool in Google Search Console and click “View crawled page” to see what Google actually sees
• Where possible, use server side rendering (SSR) or static generation so the main content is in the HTML from the start
• Make sure links are real links (an a tag with an href), not buttons that only work with JavaScript
• Do not hide important content behind tabs, clicks or infinite scroll that bots cannot trigger

If your content only appears after JavaScript runs, you may be invisible to many AI tools, even if Google ranks you.

Level 4: Local technical SEO for Liverpool businesses

This is where most generic guides stop and where Liverpool businesses can pull ahead. Local technical SEO connects your website to Google Maps, the local map pack and “near me” searches.

Build location pages the right way

Create one strong main Liverpool page first. Only add area pages, such as Liverpool City Centre, Wavertree, Allerton, Crosby, Bootle, Birkenhead, St Helens or Knowsley, if you genuinely serve those areas and can say something unique about each one.

Avoid “doorway pages”. These are dozens of pages where only the town name changes. Google treats them as spam. Each area page should include real local proof: jobs you completed there, photos, customer reviews from that area, local landmarks and travel times.

Buyer behaviour also changes across the city region. A creative agency in the Baltic Triangle searches differently from a tradesperson in Huyton or a dental practice on the Wirral. Mention postcodes naturally where relevant, for example L1 to L38 for Liverpool, CH for Wirral and WA for St Helens and Warrington.

Local Business schema and NAP consistency

Add LocalBusiness structured data (schema.org, written in JSON-LD) to your homepage or contact page. Use the most specific type you can, such as Plumber, Dentist, LegalService or Restaurant. Include:

• Business name, full address and postcode
• UK phone number in international format (for example +44 151 …)
• Opening hours, geo coordinates and the areas you serve
• Links to your Google Business Profile, Facebook, LinkedIn and other profiles using the sameAs property

Your NAP (name, address, phone number) must match exactly everywhere: your website, Google Business Profile, Bing Places, Apple Business Connect, Yell, Thomson Local and industry directories. Small differences, such as “St” versus “Street”, can weaken local trust signals.

Inconsistent or incorrect business details can also lead to problems with your listing. If that has already happened, read our guide on how to fix a suspended Google Business Profile.

On your contact page, embed a Google Map and make sure the website link in your Google Business Profile points to the right page.

UK rules that affect SEO

• UK GDPR and PECR cookie consent: cookie banners often cause layout shift and block content on mobile. Set them up so they load fast and do not cover the page. Use Google Consent Mode v2 so you do not lose most of your analytics data.
• Accessibility: the Equality Act 2010 and WCAG 2.2 guidelines overlap heavily with SEO. Alt text, clear headings, good colour contrast and keyboard navigation help both users and rankings.
• Local details: show prices in pounds (£), be clear about VAT, and use UK date formats.

UK geo-targeting signals

• A .co.uk or .uk domain sends a clear UK signal. A .com domain works too, as long as content, address and phone number are clearly UK based.
• Set the language to English (UK) in your HTML (lang=”en-GB”).
• Only use hreflang tags if you have separate versions for other countries, such as Ireland or the US. Check that each version links back correctly.

Level 5: Advanced technical SEO

These checks matter most for larger sites, e-commerce stores, property portals and businesses that want to lead their market, including in AI search.

Structured data beyond local

Schema markup helps Google understand your content and can earn rich results such as star ratings, breadcrumbs and event listings. Useful types include Organization, WebSite, BreadcrumbList, Service, Product and Offer, Article, FAQPage, Event and Person. Event schema is especially useful for Liverpool’s busy hospitality, music and football match day scene.

Add author details with Person schema and link them to real profiles. This supports E-E-A-T (experience, expertise, authoritativeness and trustworthiness), which Google uses to judge quality. Test everything with the Rich Results Test and watch the Enhancements reports in Search Console. Never mark up reviews you wrote about your own business.

Log file analysis and crawl budget

Server log files show exactly which pages Googlebot and Bingbot visit and how often. For sites with thousands of URLs, this reveals wasted crawl budget on old URLs, filter pages and redirects. Use a tool such as the Screaming Frog Log File Analyser to check that new Liverpool pages are being crawled quickly.

Website migrations

A redesign, domain change or move to a new CMS is the most common way local businesses lose rankings overnight. Before launch, map every old URL to its new URL with a 301 redirect, crawl both versions and compare. Keep your staging site password protected and set to noindex. After launch, watch Search Console daily for at least four weeks.

Edge SEO

When your CMS or developer is slow to make changes, a CDN such as Cloudflare can apply redirects, headers and schema at the “edge” before pages reach the user. This is a fast way to fix technical issues on large or locked down sites.

Technical SEO for AI search and LLMs

Large language models (LLMs) such as ChatGPT, Google Gemini, Claude, Perplexity and Microsoft Copilot now answer many questions people used to type into Google. Google AI Overviews and AI Mode show AI written summaries at the top of results. To be mentioned or cited, your site needs to be easy for these systems to access and understand.

• Let the right bots in: check robots.txt for AI crawlers such as GPTBot and OAI-SearchBot (OpenAI), PerplexityBot, ClaudeBot and Google-Extended. Blocking or allowing them is a business decision, but block them by accident and you disappear from AI answers.
• Serve content in plain HTML: many AI crawlers do not run JavaScript. Key facts about your services, prices and locations should be in the page’s HTML.
• Consider an llms.txt file: a simple text file at yourdomain.co.uk/llms.txt that points AI tools to your most important pages. It is a new, optional idea and not a ranking factor, but it is cheap to add.
• Strengthen your entity: search engines and LLMs think in “entities”, meaning clearly defined things such as your business, your founder, your services and Liverpool itself. Use consistent names everywhere, Organization and LocalBusiness schema, sameAs links and, where you qualify, a Wikidata entry. This helps you appear in Google’s Knowledge Graph.
• Earn local mentions: AI tools trust businesses that others talk about. Coverage in the Liverpool Echo, Liverpool Business News, Downtown in Business or trade bodies builds that trust.
• Write answer ready content: clear headings, short direct answers and FAQ sections make it easy for AI tools to quote you.
• Track AI visibility: check whether ChatGPT, Perplexity and AI Overviews mention your business for your main searches, and look for AI referral traffic in Google Analytics 4.

Monitoring and reporting

Technical SEO is not a one off job. Run an automated crawl every week, set alerts for robots.txt changes, new noindex tags and server errors, and review Core Web Vitals monthly. Use a local rank tracker with a grid view, such as Local Falcon or BrightLocal, because map pack rankings can change from one Liverpool street to the next.

Your technical SEO priority checklist

You do not need to fix everything at once. Sort issues by impact, effort and how many pages they affect.

Priority	When to fix	Examples
Critical	This week	Site blocked in robots.txt, noindex on key pages, broken HTTPS, money pages returning errors
High	This month	Core Web Vitals failures, wrong canonicals, duplicate location pages, missing LocalBusiness schema, NAP mismatches
Medium	Next 1 to 2 months	Internal linking, image optimisation, redirect chains, sitemap clean up
Strategic	This quarter	Log file analysis, edge SEO, AI crawler access, entity building, llms.txt

Quick self check:

• Google Search Console and Bing Webmaster Tools are set up
• robots.txt does not block important pages
• All key pages are indexed
• Only one HTTPS version of the site loads
• XML sitemap is clean and submitted
• Mobile pages pass Core Web Vitals
• Main content is visible without JavaScript
• LocalBusiness schema and matching NAP are in place
• Location pages are unique and useful
• AI crawlers are allowed or blocked on purpose, not by accident
