What is SEO? A beginner’s guide to search engine optimisation

When you need information, a product or a service, you most likely start with a search engine – and so do your customers and students. The site that appears in the first results gets a golden chance to be seen and visited, without paying for each click. The organised work that improves your site’s chances of appearing in the natural (unpaid) results is called search engine optimisation, or SEO. Many people think SEO is a set of secret tricks for fooling Google; the truth is the opposite. Successful SEO means making your site the best possible answer to what your audience is looking for, and making that clear to search engines. In this guide we explain the parts of SEO, compare them, and set out a practical plan for getting started.

SEO and paid ads: what is the difference?

A Google results page has two kinds of result: ads, marked “Ad” or “Sponsored”, whose owners pay to appear or for each click; and organic results, which Google orders by its judgement of each page’s relevance and quality and which cannot be bought. Ads give you quick visibility for as long as you pay, and stop when the payments stop. SEO is a slower investment at first, but its results build up and last. Most successful projects combine the two wisely, but understanding SEO is essential either way, because the quality of your page even affects how efficient your ads are.

The four pillars of SEO

1. Technical SEO

This is the foundation everything rests on. If Google cannot crawl and index your pages, the best article in the world will not help you. Technical SEO covers the robots.txt file, the sitemap, site speed, mobile-friendliness, HTTPS, avoiding duplicate pages, and handling deleted pages and redirects correctly. We explained crawling and indexing in how Google Search works, and we go deeper into speed and user experience in technical SEO and Core Web Vitals.

2. Content

Content is the reason a searcher is on your site at all. The question to ask before writing any page is: what is the person actually looking for, and is my page the best answer to it? Google’s guidance recommends helpful, reliable content written for people first, reflecting experience, expertise, authoritativeness and trustworthiness – a set of criteria known as E-E-A-T. On an educational site, for example, an article by a teacher who has actually taught, sharing examples from their own class, is very different from a generic article of borrowed ideas. The starting point for knowing what people search for is keyword research.

3. On-page SEO

This is about how the content itself is presented:

• The title tag: the title shown in search results and the browser tab. Make it clear, specific and include the main topic.
• The meta description: the short text under the title in results. It does not directly affect ranking, but it affects whether the searcher decides to click.
• Headings: one main H1 heading, then organised H2 and H3 headings that help readers and search engines understand the structure.
• Images: sensibly sized, with alternative (alt) text describing their content – which also matters for accessibility for blind users.
• Internal links: links with descriptive text between your related pages.
• The URL: short, readable and descriptive of the page.

4. Reputation and links

When trusted sites point to your page with a link, it is a sign your content is worth something. But quality matters more than quantity here: one link from a well-known educational site in your field is worth more than hundreds from random sites. Google explicitly warns against buying links or exchanging them heavily to manipulate rankings. The sustainable approach is to create content worth pointing to – a thorough guide, a useful free tool, a real case study – and then let people know about it.

The following video from Search Engine Land explains the idea of SEO concisely:

Local SEO: if people visit you in person

If your business has a physical location – a learning centre, a clinic or a shop – there is an important extra side called local SEO. When someone searches for “coding courses for kids” near them, Google often shows a map and nearby businesses. To appear there, create a free Google Business Profile and fill in your name, address, phone number and opening hours accurately, making sure they match your website exactly. Encourage your real customers to leave reviews, and reply to them respectfully, whether positive or negative. And never write fake reviews for yourself: it breaks Google’s policies and destroys the trust you are trying to build.

Practices that harm your site

• Keyword stuffing: repeating a search phrase unnaturally makes the text poor for readers, and Google treats it as a bad practice.
• Copied content: copying articles from other sites adds no value and may also expose you to legal problems.
• Producing many thin pages: hundreds of short, similar pages designed only to catch search phrases.
• Hiding text from readers while showing it to search engines: outright deception that can lead to a penalty.
• Promises of “page one in a week”: nobody can guarantee a particular ranking in Google, and Google itself warns about such promises.

A four-week plan to get started

1. Week one – the technical foundation: set up Search Console, submit your sitemap, and make sure your important pages are indexed.
2. Week two – understanding your audience: list the questions your customers or students ask, and research the keywords related to them.
3. Week three – improving what exists: review the titles and descriptions of your ten most important pages, and add internal links between them.
4. Week four – new content: write one excellent page answering the most important question on your list, then measure its performance over the following weeks, as we explain in measuring digital marketing.

How long does SEO take to work?

There is no fixed time; it depends on the site’s age, the strength of competition in your field, the quality of what you offer and how steadily you work. Google’s guidance notes that the effect of changes can take anywhere from weeks to months to show. So treat SEO as an ongoing habit, not a project that ends in a week.
