SEARCHSEO
Search engine optimisation (SEO) is the discipline of making a business findable, understandable and trusted by the systems people use to search, from classic results pages to AI-generated answers. It combines technical foundations, content that genuinely answers buyers' questions and a reputation others vouch for, and it compounds over time rather than stopping when spend stops.
How we
see it
Most SEO advice is written as if search were a puzzle to be solved: find the right keywords, the right tags, the right number of links, and the rankings will follow. Our view is different. Search engines and AI assistants are trying, imperfectly but relentlessly, to find the most useful and trustworthy answer to a question. The durable way to win is to become that answer for the questions your buyers actually ask, and to remove every technical reason a machine might have for overlooking you. Tactics that try to look useful without being useful tend to work briefly and fail at the worst moment.
That makes SEO less a marketing channel than an operating discipline. It touches engineering, because templates and rendering decide what search engines can read. It touches product and sales, because the best content comes from the people who know customers' questions and objections. It touches leadership, because the returns compound slowly and are easily cancelled by anyone judging SEO on a paid-media timetable. The businesses that do well treat search as a long-term asset with an owner, a plan and honest measurement, not as a monthly retainer for a black box. The deciding factor is rarely a clever tactic; it is whether someone inside the business has the authority to get templates fixed, experts interviewed and weak pages retired.
This library is organised to reflect that. Start with the foundations: what SEO is, how intent shapes every page and how to read demand through keyword research. Then go deeper into the technical, on-page and authority work, the specialist contexts of local, ecommerce, B2B and international search, and the newer disciplines of generative and answer engine optimisation, which we treat as extensions of good SEO rather than replacements. Every guide is written to be useful on its own and to say something a smart reader could disagree with. None of them contains invented statistics; where numbers appear, they are platform definitions or clearly labelled illustrations. Where platforms change often, we describe the principle and point you to current documentation. Each article ends with takeaways and frequently asked questions, and links to related guides across the library, so you can follow a subject as far as your situation requires and stop when you have what you need.

FourConvictions
- 01
Intent before keywords
Every page should do one job that searchers need done, in the format the results reveal. Keywords follow from that, not the other way round.
- 02
Foundations cap everything
A page that cannot be crawled, rendered or indexed cannot rank, however good it is. Fix the base of the stack before polishing the top.
- 03
Earn, never engineer
Links, reviews and mentions that are bought or manufactured breach guidelines and erode trust. Create things worth citing and tell the people who would care.
- 04
Measure outcomes, report honestly
Judge SEO on non-brand business outcomes, track leading indicators while results build, and state the limits of attribution plainly.

- Explainer8 minWhat Is SEOEarning the click you never paid forSEO (search engine optimisation) is the practice of making a website easy for search engines to crawl, understand and trust, so that its pages appear when people search for what the business offers. It combines technical foundations, useful content and external credibility, and it compounds over time rather than stopping when spend stops.2 diagrams2 tools
- Guide9 minTechnical SEORemoving the reasons not to rankTechnical SEO is the work of making a website easy for search engines to discover, crawl, render and index, and of removing ambiguity about which URL is the real version of each page. It does not make content better; it makes sure good content is seen. Prioritise by how many important pages an issue affects.2 diagrams2 tools
- Guide9 minOn-Page SEOBuilding the page that deserves to winOn-page SEO is the optimisation of an individual page's content and markup so that search engines understand what it is about and judge it the most useful result for a specific query. It covers intent match, titles, headings, copy, media, internal links and evidence of expertise. Intent match matters most; tags matter least.2 diagrams2 tools
- Guide9 minLink BuildingEarning references worth havingLink building is the work of getting other websites to link to yours. Search engines treat relevant links from trusted sites as evidence that a page is worth showing. The durable approach is earning links by creating things others want to cite, not buying or swapping them, which breaches search engine guidelines and carries real risk.2 diagrams3 tools
- How-to9 minKeyword ResearchReading demand, not listsKeyword research is the process of finding the words and questions people use when searching for what a business offers, then judging which are worth targeting. Good research reads intent, value and feasibility, not just search volume, and ends in a page plan: which page will answer which group of queries, in what order.2 diagrams2 tools
- Explainer9 minSearch IntentThe question behind the querySearch intent is the goal behind a search: what the person actually wants to achieve when they type or speak a query. Search engines rank pages that satisfy that goal, so matching intent is the first condition of ranking. Intent is best read from the live results page, which shows what the engine believes satisfies the query.3 diagrams2 tools
- Guide9 minLocal SEOWinning the search on your streetLocal SEO is the work of making a business visible when people search for products or services near them, in map results and local listings as well as ordinary web results. Google says local results weigh relevance, distance and prominence. You control relevance and prominence through an accurate Business Profile, reviews, local pages and consistent citations.2 diagrams2 tools
- Guide9 minEcommerce SEOCategories first, products secondEcommerce SEO is the practice of making an online store's categories, products and supporting content visible in search. For most stores the biggest gains come from category pages, which match broad commercial queries, and from controlling faceted navigation so filters do not create endless duplicate URLs. Product pages win long-tail and branded product searches.2 diagrams3 tools
- Guide9 minB2B SEOLow volume, high stakes, long memoryB2B SEO is search optimisation for businesses that sell to other businesses, where search volumes are small, deals are large and several people influence each purchase. It focuses on problem-led and comparison queries, content for each stakeholder in the buying group, and measurement in qualified pipeline and revenue rather than traffic.2 diagrams3 tools
- Guide9 minInternational SEOOne brand, many markets, no confusionInternational SEO is the work of helping search engines show the right version of a website to people in each country and language. It involves choosing a URL structure for each market, signalling language and regional alternates with hreflang, and localising content genuinely rather than translating it. Most failures come from duplicate markets and broken hreflang.2 diagrams2 tools
- Checklist10 minSEO Audit ChecklistFinding what actually holds you backAn SEO audit is a structured review of a website to find the issues that most limit its search visibility and the opportunities most likely to grow it. A useful audit is prioritised, not exhaustive: it checks measurement, indexing, technical health, content and intent, internal links and authority, then ranks fixes by business impact and effort.2 diagrams3 tools
- Explainer9 minCore Web VitalsSpeed as users feel itCore Web Vitals are Google's metrics for real-user page experience: Largest Contentful Paint (loading), Interaction to Next Paint (responsiveness) and Cumulative Layout Shift (visual stability). A page passes when at least 75 per cent of real visits meet the 'good' threshold for each. They are a modest ranking consideration and a significant conversion one.2 diagrams2 tools
- How-to9 minSchema MarkupTelling machines what you meanSchema markup is structured data, usually written in JSON-LD using the schema.org vocabulary, that describes a page's content to machines: this is a product with this price, this is an organisation with this address. It can make pages eligible for rich results and helps search and AI systems understand entities. It never replaces visible content.2 diagrams3 tools
- How-to9 minInternal LinkingSpending the authority you already haveAn internal linking strategy is a deliberate plan for how pages on a site link to each other, so that search engines can discover every important page, understand how topics relate and pass authority to the pages that matter most. It is the cheapest SEO lever most sites have, because it uses authority they already own.2 diagrams2 tools
- How-to9 minContent PruningLess, but better, on purposeContent pruning is the deliberate review of a website's existing pages to improve, merge, redirect or remove those that no longer serve readers or the business. Done carefully, it concentrates quality and authority on fewer, stronger pages and reduces cannibalisation. Done carelessly, it deletes pages that were quietly earning links, visits or conversions.2 diagrams2 tools
- Framework9 minTopic ClustersOwning a subject, not a keywordA topic cluster is a group of pages that together cover a subject comprehensively: one pillar page giving a broad overview, linked to cluster pages that each answer a specific sub-question in depth, all linking back. Clusters make topical expertise visible to search engines and readers, and pool authority across related pages.3 diagrams2 tools
- Comparison9 minSEO vs PPCRenting attention or building itSEO earns unpaid visibility in search results through technical, content and authority work; PPC (pay-per-click) buys visibility through ads charged per click. PPC is fast, controllable and stops when spending stops. SEO is slower, harder to control and compounds over time. Most businesses with search demand benefit from both, used for different jobs.2 diagrams2 tools
- Guide10 minGenerative Engine OptimisationBeing the source AI repeatsGenerative engine optimisation (GEO) is the practice of making a brand and its content more likely to be accurately described and cited by AI systems that generate answers, such as AI search summaries and chat assistants. It builds on SEO fundamentals and adds emphasis on clear, specific, quotable content, consistent entity information and reputation across credible sources.2 diagrams2 tools
- Guide9 minAnswer Engine OptimisationBuilt to be quotedAnswer engine optimisation (AEO) is the craft of structuring content so that search features, voice assistants and AI answer systems can extract a clear, accurate answer from it and attribute it to you. It relies on question-led structure, direct answers in the first sentences of sections, self-contained passages and supporting depth for readers who click through.2 diagrams2 tools
- Checklist10 minSite Migration SEOMoving house without losing the postA website migration is any significant change to a site's domain, URLs, platform, structure or design that can affect how search engines crawl, index and rank it. Migration SEO protects existing visibility through a full URL inventory, one-to-one redirect mapping, pre-launch testing on staging, careful launch checks and close monitoring for several weeks afterwards.2 diagrams3 tools
- Explainer9 minE-E-A-TShowing why you should be believedE-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness, a framework in Google's Search Quality Rater Guidelines for judging content quality. Trust is the most important element. E-E-A-T is not a single ranking factor or score; it describes qualities Google's systems aim to reward, which sites demonstrate through real expertise, transparency and reputation.2 diagrams3 tools
- Framework9 minSEO KPIsReporting what leaders can act onSEO KPIs are the measures that show whether search optimisation creates business value. A useful framework has three tiers: business outcomes such as revenue and qualified leads from non-brand organic search; leading indicators such as visibility for priority topics; and health metrics such as indexing. Report each tier to the audience that can act on it.2 diagrams2 tools
- Guide10 minProgrammatic SEOScale only what deserves to existProgrammatic SEO is the practice of generating many search-targeted pages from a template and a structured dataset, such as one page per city, product combination or integration. It works when each page answers a real, distinct query with genuinely useful data. Without unique value per page, it becomes scaled content abuse, which search engine policies explicitly target.2 diagrams2 tools
- How-to10 minChoosing an SEO AgencyHiring for judgement, not promisesTo choose an SEO agency, first define the business problem and what success means, then judge agencies on the quality of their diagnosis, the people who will do the work, how they measure outcomes and how transparent they are about methods. Reject guaranteed rankings and secret techniques. The best signal is how well they understand your situation before you hire them.2 diagrams3 tools
SearchQuestions
- What is SEO in simple terms?
- SEO is the work of helping a website's pages appear when people search for what the business offers. It involves making the site easy for search engines to read, publishing pages that answer people's questions better than alternatives, and earning credibility from other websites. Done well, it produces visits without paying per click.
- How long does SEO take to show results?
- It depends on the site's starting point, the competitiveness of the market and the amount of work done. Technical fixes and improvements to pages already ranking can show effects within weeks to a few months. Broader authority and business results usually take two to three quarters or longer.
- Is SEO still worth it with AI search?
- Yes. AI answer features and assistants draw on content they can crawl, understand and trust, which is what SEO builds. Some simple queries now produce fewer clicks, so measurement must include visibility in answers, but the case for being the clearest, most credible source has grown stronger.
- Should I do SEO in-house or hire an agency?
- Many businesses combine both: an internal owner who understands the business, with specialist help for audits, technical work, migrations or content at scale. The right balance depends on your size, the complexity of your site and how much expertise you can hire and retain internally.
