What is SEO, in plain terms?
Search engine optimization is the practice of making a website more likely to appear in search results for the queries its customers actually type, and more likely to be chosen once it appears. It has three parts that have to work together: technical foundations that let a search engine crawl and understand the site, content that answers what people are looking for, and references from elsewhere on the web that signal the site can be trusted.
The common misconception is that SEO is a set of tricks applied to a finished website. In practice most of the leverage sits in decisions made before and during a build — page structure, heading hierarchy, how content renders, what each URL is allowed to say it is about — which is why retrofitting SEO onto a site that was built without it is slower and more expensive than getting it right the first time.
How long does SEO take to work?
Technical fixes can show movement within weeks, particularly where the problem was that search engines could not crawl or understand pages at all. Content and authority take longer, and three to six months is a realistic horizon before organic traffic trends are clearly attributable to the work rather than to normal variance.
Anyone promising first-page positions in thirty days is describing paid advertising, or a query nobody searches for. The honest shape of an SEO programme is a slow start, then compounding: early months produce little visible change while foundations and content are established, and later months produce disproportionate growth because each new asset benefits from the authority the previous ones accumulated.
What are the three pillars of SEO?
Technical SEO is whether search engines can find, render and understand your pages. Content SEO is whether those pages answer what people are searching for better than the alternatives. Authority is whether other sites and sources point to you as a credible answer. Weakness in any one limits the other two.
The dependency runs in a specific order, which is why the sequence matters. Content cannot rank on pages that cannot be crawled. Authority cannot help pages that do not target a real query. And neither compensates for a site that is slow enough that visitors leave before reading it — which is why speed sits inside the technical pillar rather than being treated as a separate concern.
The three pillars and what each covers
- Technical — crawlability, indexing, site architecture, page speed, structured data, canonical tags, redirects
- Content — query research, page structure, heading hierarchy, depth, internal linking, freshness
- Authority — earned links, brand mentions, citations in the sources that answer engines trust
Why is technical SEO usually the first priority?
Because content and authority are wasted on pages that search engines cannot properly access. The problems we find most often are not exotic: pages blocked by a stray robots rule, duplicate content competing with itself because canonical tags are missing, content that only appears after a script runs and is therefore invisible to a crawler, and a site architecture so deep that important pages are five clicks from the home page.
Technical work is also the cheapest to fix and the easiest to verify, which makes it a sensible place to start for a reason beyond its importance. It produces concrete before-and-after evidence within weeks, so you can confirm the diagnosis was right before committing budget to the slower content and authority work.
How do you decide what content to write?
Start from the queries your buyers type when they are close to a decision, then work outwards. The pages that produce enquiries are usually not the pages with the highest search volume. A phrase with a few hundred monthly searches and obvious commercial intent will out-earn one with tens of thousands of searches from people who are not buying anything.
Group queries by the job behind them rather than by keyword string. One good page answering a complete question consistently outperforms five thin pages each covering a fragment, because the search engine has to choose one page per query and thin pages compete with each other for the same slot. Before writing anything, check whether an existing page should simply be improved instead of a new one created — that decision prevents most self-inflicted cannibalisation.
What is AEO and how does it differ from SEO?
Answer engine optimization targets being the answer that gets extracted and read aloud, rather than one of ten links competing for a click. It matters because a growing share of searches now end without a visit to any website: the result page shows the answer directly, or an assistant states it in a sentence.
The tactics overlap with SEO but the emphasis shifts. AEO rewards pages that answer a question in the first sentence under a heading phrased the way a person would ask it, that define their terms explicitly, that use question-and-answer structure with real questions, and that state facts in self-contained sentences which remain correct when lifted out of context. Vague introductions, throat-clearing and pronoun-heavy prose are invisible to an answer engine even when the underlying content is good.
SEO, AEO and GEO compared
Three related disciplines with different surfaces and different definitions of success. A page built only for one of them underperforms on the others.
| Discipline | Optimises for | Primary surface | Success signal |
|---|---|---|---|
| DisciplineSEO | Optimises forRanking in a list of links | Primary surfaceSearch results pages | Success signalPosition, clicks, organic enquiries |

| DisciplineGEO | Optimises forBeing cited by a generative model | Primary surfaceAI assistants and AI-generated overviews | Success signalYour brand named in a generated answer |
What is GEO and why does it matter now?
Generative engine optimization is the work of being cited when an AI system answers a question in your category. The mechanism is different from ranking: a generative model does not return a list of pages, it synthesises an answer from sources it considers reliable and names some of them. Being one of those named sources is the new visibility, and it is not automatically inherited from ranking well.
What appears to earn citations is fairly consistent. Pages that state facts plainly and specifically, with numbers and named entities, are easier to quote than pages that hedge. Pages with clear definitions and structured comparisons get lifted more readily than narrative prose. Consistency of your entity across the web — the same description of what you do, in the same terms, on your own site and in directories and profiles — helps a model resolve you as a distinct thing rather than a name it half-recognises. And because models weigh sources they treat as authoritative, the authority work that SEO already required is now doing double duty.
The practical implication is that the content on this page is written the way it is on purpose. Short declarative facts, explicit definitions, a comparison table, and a named glossary are all more extractable than the same information delivered as flowing prose.
How do you measure SEO without fooling yourself?
Track qualified organic sessions and the enquiries they produce, not raw traffic. Organic traffic can rise comfortably while enquiries fall, if the growth is in informational queries from people who will never buy — and that pattern is common enough that traffic alone is a poor success metric.
Set the baseline before you start, because almost every SEO report looks impressive against no baseline. Record current positions for the target queries, current organic entry pages, and current enquiry volume from organic. Then report the same three numbers monthly with the same definitions, so that a change means something. Be explicit about the things that move rankings for reasons outside your control — competitor activity, algorithm updates, seasonality, and the fact that search results now absorb clicks that used to reach websites.
