SEO Basics: How Search Works and What to Do First, Explained for Beginners

This guide covers SEO basics for beginners, in the order you will need them. No jargon without an explanation, no tricks: just what search engines do, what they expect from your site and which first actions make the most difference. For a short definition, see our glossary entry on SEO.

What is SEO and why does it matter?

SEO is the set of practices that helps a website appear higher in the unpaid results of search engines such as Google and Bing. Those organic results are where people look for answers, products and providers, and every click on them is free.

SEO matters because it builds a lasting source of visitors. An ad stops sending traffic the day you stop paying; a page that ranks keeps working for months or years. It also brings visitors at the moment they express a need, which makes them more likely to read, sign up or buy.

How do search engines work?

Google discovers pages by crawling, stores and analyses them in its index, then selects and orders the best ones for each search. Google describes these three stages in its guide on how Search works:

A page that is never crawled or indexed cannot rank, whatever its quality. Our glossary entry on crawling and indexing details both steps.

How do you choose the right keywords?

Choose the words your customers actually type, then match each important query to one page that answers its intent. A keyword is a search query; what matters is the need behind it, called search intent.

• Start from your customers: list their questions, problems and the words they use.
• Check the results: search each query on Google and look at what ranks (guides, product pages, comparisons, local results). That shows the format Google expects.
• Prefer specific queries at first: "how to repot an orchid" is easier to win than "orchids", and the visitor's need is clearer.
• One topic, one page: avoid several pages competing for the same query.
• Use free sources: Google autocomplete, "People also ask", Search Console queries and Google Keyword Planner.

What is on-page SEO?

On-page SEO is everything you optimise inside a page: the content, the title, the headings, the URL, images and internal links. It is where beginners get the fastest results, because every element is under your control.

1. Title tag: unique, descriptive, with the main keyword near the start; it is the clickable line in results.
2. Meta description: a short summary that encourages the click (Google may rewrite it).
3. One H1 and clear subheadings: they structure the page for readers and engines.
4. Content that answers: lead with the answer, then detail, examples and data; Google's guidance asks for helpful, reliable, people-first content.
5. Readable URL: short words separated by hyphens.
6. Images: descriptive file names and alt text.
7. Internal links: link related pages with descriptive anchors so visitors and Googlebot find them.

What is technical SEO?

Technical SEO ensures search engines can access, render and index your site, and that visitors get a fast, stable experience. Beginners do not need to master every detail, but a few checks prevent most problems:

• HTTPS: a secure site is the norm.
• Mobile friendly: Google uses mobile-first indexing, so the mobile version of a page is the one it evaluates.
• Speed and stability: Core Web Vitals measure loading (LCP), responsiveness (INP) and visual stability (CLS).
• robots.txt and noindex: make sure you are not blocking pages you want in results.
• XML sitemap: list your important URLs and submit the file in Search Console.
• No broken pages: fix 404 errors on linked pages and use 301 redirects when a URL changes.

Why do backlinks matter?

Backlinks, links from other sites to yours, help Google discover pages and judge how much the web trusts them. A few relevant links from respected sites in your field count far more than many links from unrelated ones.

The safe way to get them is to publish things worth citing (original data, useful guides, tools) and make them known. Buying links or trading them in bulk breaks Google's spam policies. Our guide on how to get backlinks lists the methods that work.

How do you measure SEO results?

Measure impressions, clicks, positions and conversions over months, using Google Search Console and your analytics tool. Search Console is free and shows which queries display your pages, how often people click and which pages have indexing problems.

SEO is slow by nature. Our page on how long SEO takes explains what to expect month by month.

How does SEO connect with the AIs?

ChatGPT, Gemini, Perplexity, Claude and Google's AI Overviews often build their answers from pages that search engines have indexed and rank well, so SEO is the foundation of AI visibility. Optimising to be quoted in those answers is called GEO (generative engine optimisation).

The same basics apply, with extra weight on a few habits: answer the question in the first sentences of each section, keep passages self-contained, cite sources and figures, and make sure your brand is described consistently across the web. A page that is clear for a beginner is usually clear for an AI too.

Conclusion

SEO basics come down to being crawlable, answering real searches better than others, earning trust from other sites and measuring patiently. Set up Search Console, fix technical blockers, map one keyword to one page, write content that leads with the answer and link your pages together.
