What Is SEO? A Plain-English Guide for UK Businesses
SEO (search engine optimisation) is the process of improving a website so it appears higher in Google’s unpaid search results for the searches your customers make. In the UK, where Google handles the vast majority of searches, SEO covers technical health, helpful content, local listings such as Google Business Profile, and links from other trusted websites.

How SEO works
Google uses automated crawlers to discover pages, stores them in its index and then ranks them for each search based on hundreds of signals. Google groups the most important ones into relevance (does the page match the search?), quality (is it helpful, expert and trustworthy?), usability (is it fast and easy to use?) and context (where is the searcher and what do they want?).
SEO is the work of making sure your site performs well on all of those – without paying Google for the position. Paid results (Google Ads) are separate and stop when you stop paying.
The four main types of SEO
| Type | What it covers |
|---|---|
| Technical SEO | Crawling, indexing, speed, mobile usability, structured data |
| On-page / content SEO | Pages that answer what people search for, with clear titles and headings |
| Local SEO | Google Business Profile, map pack, reviews, citations for local searches |
| Off-page SEO | Links and mentions from other trusted websites |
Read more on each: technical SEO, content SEO, local SEO and link building.
SEO in the UK: what is different?
- Local intent: many UK searches include a town or “near me”, so local SEO matters for most service businesses.
- UK English: spelling and terms (optimisation, solicitor, postcode) affect relevance.
- Google.co.uk dominance: Google is by far the most used search engine in the UK, so most SEO work focuses on it.
- Regulated sectors: UK legal and financial firms must also meet SRA or FCA rules in their content.
SEO and AI search
Google AI Overviews and chatbots like ChatGPT now answer many questions directly, but they draw on pages that rank and are clearly structured. Modern SEO therefore also aims to make your business the source those AI tools cite – often called GEO or AI search optimisation. See AI search optimisation.
Getting started with SEO

- Claim and complete your Google Business Profile
