What SEO is, and what it is not
Google defines search engine optimisation (SEO) as techniques aimed at improving a website's visibility in Google Search results. Keep two words in mind: visibility and improving. SEO makes your pages easier for search engines to find and understand, and more useful to the people searching. It does not give you any control over Google.
SEO can:
- Help Google discover, process and understand your pages.
- Match your content to the words real customers type.
- Make your listing clearer and more attractive in the results.
- Make your pages eligible for search features and for links in AI answers.
SEO cannot:
- Guarantee any position. Google says plainly: "No one can guarantee a #1 ranking on Google."
- Buy a better position in the free results. Google states that it "doesn't accept payment to crawl a site more frequently, or rank it higher."
- Guarantee inclusion at all. Google does not promise to crawl, index or show a page, even when that page follows Google Search Essentials.
What this means in practice: if an agency promises "page one in 30 days", says it has a special relationship with Google, or offers "priority submission", treat that as a red flag. Google itself warns against these claims. An honest SEO promises work, a method and measurement, never a ranking.
The two halves of a results page: paid and organic
Every Google results page mixes two kinds of listing:
- Paid results (ads). Advertisers bid to appear for a query. Since October 2025 Google groups text ads under one "Sponsored results" label that stays visible as you scroll, and users can click "Hide sponsored results" to collapse them. Shopping ads carry the Sponsored label too. Ads are bought through Google Ads, which is a separate system from organic ranking.
- Organic results. These are the unpaid listings Google chooses for the query. SEO works only on this half.
One misunderstanding is very common, so be clear on it: spending money on ads does not raise your organic rankings. The two are separate.
The anatomy of an organic result
Google's own name for a standard listing is a text result. Its parts are:
- Title link: the clickable headline.
- Snippet: the short description underneath.
- Attribution: the site name and domain, often with a favicon (the small site icon).
- Breadcrumb: where the page sits within the site.
- Byline date: an estimated publication or update date, when Google shows one.
- Sitelinks: extra links to the same site, usually on brand searches.
- Rich attributes: extras such as review stars, which usually come from structured data.
Search features beyond the plain links
Many results pages also include search features, for example:
- Rich results: listings with graphical or interactive extras, usually powered by structured data.
- Image results and video results.
- People also ask: a group of related questions, each of which expands to show an answer and a source.
- Related searches: queries Google generates automatically, usually near the bottom of the page.
The layout changes with device, location, language and the intent behind the query. Two people searching the same words can see different pages.
AI Overviews and AI Mode
- An AI Overview is an AI-generated summary at the top of some results pages. It helps people "get to the gist" of a topic and includes links to the sources it draws on.
- AI Mode is a separate, conversational search experience for questions that need more reasoning, exploration or comparison.
Both use a technique Google calls query fan-out: they run several related searches across subtopics to build an answer, which means they can link to a wider range of sites than a standard results page. Google says there are no additional requirements and no special optimisations for appearing in either one. A page has to be indexed and eligible to appear in Search with a snippet. Ordinary SEO fundamentals are what qualify you.
Task 1: Label a live results page
DO this now, and allow about 10 minutes:
- Open a private or incognito browser window, so that your search history has less effect on the results.
- Search for something a customer would type to find a business like yours, such as "emergency plumber Leeds" or "best trail running shoes for wide feet".
- Take a full-page screenshot.
- Mark up the screenshot with these labels: Sponsored, AI Overview (if there is one), Organic result, and each search feature you can name (People also ask, images, videos, rich results, related searches).
- On one organic result, label the title link, snippet, attribution and favicon.
- Note where your own site appears, if it appears at all. Count the organic positions only.
- If there is an AI Overview, write down which sites it links to.
Task 2: Record three baseline queries
You cannot measure progress without a starting point. DO this:
- Write down three queries a real customer might use to find your site. Think about the customer's problem, not your internal product names.
- One problem query, for example "why is my boiler losing pressure".
- One comparison query, for example "combi vs system boiler".
- One ready-to-buy query, for example "boiler service near me".
- Search each query in a private window and record the date, your device, any organic position you hold, whether ads appear, whether an AI Overview appears, and whether it cites you.
- Save the record in a spreadsheet. You will come back to these queries as the course goes on.
Key takeaways
- SEO improves visibility in search. It cannot guarantee rankings, and anyone who promises a #1 position is not being honest.
- Google does not accept payment to rank pages higher. Ads are a separate paid product, labelled "Sponsored".
- A results page combines ads, organic text results, search features and sometimes an AI Overview.
- AI Overviews and AI Mode have no special requirements. An indexed page that is eligible for a snippet can be shown.
- Your three baseline queries and the screenshot you labelled are your starting record.
