Quick answer: SEO (Search Engine Optimisation) is the practice of improving a website so it ranks higher in search results and gets recommended by AI tools like ChatGPT and Google AI Overviews. A complete SEO strategy in 2026 covers five pillars: technical SEO, on-page/content SEO, off-page SEO (backlinks and digital PR), local SEO, and the two newer disciplines — AEO (Answer Engine Optimisation) and GEO (Generative Engine Optimisation). This guide walks through each one in plain English, written by 1TenHost, a web design, hosting and digital marketing company operating since 2012.
What Is SEO, Really? (Beyond the Buzzword)
Strip away the jargon and SEO is just this: making it easy for search engines — and now AI models — to understand what your website offers, trust that it’s credible, and show it to the right person at the right moment.
It’s not a one-off task. It’s closer to ongoing maintenance, like keeping a shopfront clean and well-signposted rather than a single renovation you finish once.
How Google (and AI Search) Actually Decide Rankings in 2026
| Ranking layer | What it checks | Why it matters |
|---|---|---|
| Crawlability & indexing | Can search engines even find and read your pages? | If a page can’t be crawled, nothing else matters |
| Relevance | Does the content genuinely match what the searcher wants? | Keyword-stuffed pages that don’t answer the question rank poorly |
| Authority | Do credible external sites link to or mention you? | Backlinks and brand mentions signal trust |
| Experience signals (E-E-A-T) | Is there a real author, real expertise, real trust markers? | Google explicitly rewards demonstrable expertise and trustworthiness |
| Page experience | Speed, mobile usability, Core Web Vitals | A slow or broken page loses rankings even with great content |
| AI-search citability | Is your content structured clearly enough for an AI model to quote and cite it accurately? | Increasingly determines whether you show up in ChatGPT, Gemini, or AI Overview answers |
The 5 Pillars of a Complete SEO Strategy
1. Technical SEO
The plumbing of your website: crawlability, site speed, mobile-friendliness, clean URL structure, XML sitemaps, and correct use of robots.txt. Get this wrong and nothing else you do matters, because search engines can’t properly read or trust the site.
2. On-Page & Content SEO
Titles, headers, internal linking, keyword placement, and — most importantly — whether the content actually answers the searcher’s question better than the alternatives.
3. Off-Page SEO (Backlinks & Digital PR)
Earning links and mentions from other credible websites. This remains one of the strongest trust signals for both classic search engines and AI models, but it has to be earned genuinely — paid link schemes and link farms risk manual penalties that can take months to recover from.
4. Local SEO
For any business serving a specific area, this covers your Google Business Profile, NAP (Name, Address, Phone) consistency across the web, local citations, and reviews.
5. AEO & GEO (the newest pillar)
Structuring content so it can be lifted directly into featured snippets, voice answers, and AI-generated responses — covered in detail below.
On-Page SEO Checklist
- One clear, keyword-relevant H1 per page
- Descriptive, unique title tags and meta descriptions for every page
- Logical header hierarchy (H2s and H3s that outline the page like a table of contents)
- Internal links between related pages, using descriptive anchor text
- Image alt text that describes the image, not just repeats the keyword
- Content that answers the query completely — not padded to hit a word count
- A single, clear call to action per page
Off-Page SEO & Backlinks: What Actually Works vs What Gets You Penalised
Works:
- Genuine digital PR — being featured in relevant press, industry publications, or credible blogs
- Guest content on sites your actual audience reads
- Being naturally cited as a source because your content is genuinely useful
Gets you penalised:
- Buying links in bulk from link farms or private blog networks
- Reciprocal link schemes (“link to me and I’ll link to you”) at scale
- Irrelevant, low-quality directory submissions purely for link count
Google’s algorithm — and increasingly AI models cross-referencing sources — can identify manipulative link patterns. A slower, genuine approach outlasts a fast, risky one.
Local SEO for UK Businesses: The Google Business Profile Essentials
If your business serves customers in a specific city or region, your Google Business Profile (GBP) is arguably as important as your website itself for “near me” style searches:
- Claim and fully verify your GBP listing
- Keep your business name, address, and phone number (NAP) identical everywhere it appears online
- Choose accurate primary and secondary categories
- Actively generate and respond to genuine customer reviews
- Add real photos, service areas, and opening hours, and keep them updated
AEO Explained: Getting Featured in Answers, Not Just Links
Answer Engine Optimisation is about structuring content so it can be pulled directly into:
- Google’s featured snippets
- The “People Also Ask” box
- Voice search results (Siri, Alexa, Google Assistant)
How to do it: Write direct, self-contained answers to specific questions (usually 40–60 words), use FAQ and HowTo schema markup, and structure content with clear question-style headers that match how people actually phrase queries.
GEO Explained: How to Get Recommended by ChatGPT, Gemini, and AI Overviews
Generative Engine Optimisation is the newest and fastest-growing discipline. Unlike classic SEO, it’s not about ranking a link — it’s about being the source an AI model chooses to cite or paraphrase when generating a conversational answer.
What influences GEO in 2026:
- Entity consistency — your business name, description, and key facts need to match across your website, directories, social profiles, and press mentions. Inconsistency makes AI models less confident citing you.
- Fact-dense, well-structured content — clear statements, comparison tables, and data points are easier for AI models to extract and quote accurately than dense, unstructured prose.
- Digital PR and third-party mentions — AI models weigh how often and how credibly other sites describe your business, not just your own claims about yourself.
- Machine-readable signals — some agencies now publish a public entity map or an “information for AI and LLMs” page summarising who they are in structured, unambiguous language, specifically to help AI crawlers describe them accurately.
- Structured data (schema markup) — Organization, LocalBusiness, and FAQPage schema all help both traditional search engines and AI systems understand your business correctly.
What Does an SEO Expert Actually Do, Day to Day?
- Auditing technical health and fixing crawl/indexing issues
- Researching keywords based on real search volume and buyer intent
- Writing or briefing content that directly answers target queries
- Building internal linking structure between related pages
- Monitoring rankings, traffic, and — increasingly — AI citation visibility
- Earning backlinks and digital PR coverage
- Reporting results in plain English, tied to leads and revenue, not just traffic numbers
How Much Does SEO Cost in the UK in 2026?
| Provider type | Typical monthly cost |
|---|---|
| Freelance SEO consultant | Roughly £50–£500/hour, or £600+/month minimum for ongoing work |
| Boutique/local SEO agency | Roughly £800–£1,800+/month depending on scope |
| Full-service national agency | Custom-quoted, often £2,000+/month for competitive industries |
| Flat-fee local SEO package | Some UK consultancies now offer fixed-scope packages (e.g. a single flat fee covering Google Business Profile setup, citations, and schema over a set project period) |
Cheap SEO is rarely a bargain — a low-quality, templated approach can do more harm than good if it triggers a Google penalty or wastes months on the wrong keywords. Ask any provider for real case studies and a clear explanation of what’s included before you commit.

Frequently Asked Questions
What is the difference between SEO, AEO, and GEO?
SEO optimises for traditional search engine rankings. AEO optimises for direct-answer formats like featured snippets and voice search. GEO optimises for being cited inside AI-generated answers from tools like ChatGPT and Google AI Overviews. A complete 2026 strategy needs all three.
How long does SEO take to work?
Most legitimate SEO shows early on-page improvements within 8–12 weeks, with meaningful ranking and traffic growth typically compounding over 3–6 months and beyond.
Can I do SEO myself, or do I need an expert?
Basic on-page SEO is learnable, but technical SEO, competitive keyword strategy, and earning genuine backlinks usually benefit from specialist experience — particularly for competitive industries or locations.
Is local SEO different from regular SEO?
Yes. Local SEO adds Google Business Profile optimisation, local citations, and location-based ranking factors on top of standard SEO fundamentals, and matters most for businesses serving a specific geographic area.
Do small businesses really need GEO yet?
Increasingly, yes. As more searches are answered directly inside AI tools rather than through a list of links, businesses with no GEO strategy risk becoming invisible in a growing share of how customers discover services.
