SEO for beginners: how you actually get found on Google

How does SEO work? How Google crawls, indexes and ranks a website

How does Google discover a page? (crawlers and links)

Google uses bots (programs called crawlers) that follow links from one page to another across the entire web, a bit like following a thread. Without a link pointing to a page, or a sitemap flagging it, that page is very likely to stay invisible — no matter what its content is.

What is indexing, and why might a page not be indexed?

Once a page is found, Google analyses it and decides whether to add it (or not) to its index — an immense database of pages it can serve in response to a search. A page can be discovered without being indexed, if Google judges its content duplicated, too low in quality, or technically inaccessible.

How does Google decide which page to show first? (ranking)

Rankings rely on hundreds of combined signals: how relevant the content is to the query, the site's technical quality, user experience, and perceived authority (through links and mentions). None of these signals is enough on its own — a fast site with off-topic content won't rank, any more than relevant content on a site that takes 10 seconds to load.

How do Google's AI Overviews change SEO in 2026?

Google now shows AI Overviews and an AI mode in its results (Google Search Central documentation), and a large share of searches already end without a single click: 58.5% of US Google searches in 2024 (SparkToro and Datos). Understanding SEO in 2026 therefore means understanding two things in parallel: how to appear in classic links, and how to be cited in a generated answer.

Where to start with SEO as a beginner: the 3 basics

Three basics are enough to get going: a site Google can technically crawl (no accidental blocking), content that clearly answers a question people genuinely ask, and a few quality external links pointing to that content. Everything else (tools, audits, advanced strategies) refines these three basics — it doesn't replace them.

Understanding crawling, indexing and ranking: Google's official guide

Google itself details the crawling / indexing / ranking triad in its guide How Google Search works, which remains the best entry point I know for anyone discovering the topic. A bot discovers a new page mainly by following an existing link or by reading an XML sitemap; you can also flag it manually in Search Console.

What stops a page from being found on Google?

Noindex, robots.txt, orphan pages: the most frequent blockers

On the audits I run, the most frequent blocker is almost never a content problem but an access problem: a noindex tag forgotten after a migration, an overly restrictive robots.txt, or an orphan page with no internal link pointing to it. That last case is common: for Google as for a visitor, a page that nothing links to from the rest of the site simply doesn't exist.

Which reflex to adopt as soon as you publish a page? (an internal link)

Before wondering why a page doesn't rank, the first check should always be: can Google even reach it? An internal link from an already indexed page, added as soon as the page is published, solves a large share of the discovery problems I see with beginners.

Does ranking well on Google mean being visible? Organic position vs AI citation

Ranking well on Google and being visible at all are no longer quite the same thing since AI Overviews arrived en masse. A page can hold the top organic position without ever being seen if the user finds their answer directly in the summary generated above the classic results. Understanding this nuance concretely changes how content is written today: it's no longer enough to aim only for the click, you also have to aim for the citation, by answering the question clearly and directly from the first lines, rather than making readers wait until the end of the article to hold their attention longer.
