How does the Google search engine work?

The Google search engine works in three steps: crawling, indexing and ranking. Google visits pages with crawlers, stores understandable pages in a gigantic index, and determines per query which of them form the best answer. You see that order back in the SERP, the search results page.

How does Google find pages?

Google discovers new and changed pages via links and sitemaps. Crawlers follow those links, read the content and pass pages on to the index. Only what has been correctly crawled and indexed can appear in the results at all.

That is why a crawlable, fast site is so important: if Google cannot reach or read a page, it simply does not exist for the search engine, however good your content is.

How does Google determine the order?

For every query Google weighs hundreds of signals to place the best results at the top. The common thread is that Google tries to match the search intent: does someone want information, to compare or to buy. Broadly, the system looks at:

• Relevance: how well the page answers precisely this question.
• Authority: trust that shows, among other things, from references by other sites.
• User experience: speed, mobile-friendliness and usability.
• Context: location, language and earlier signals around the searcher.

Anyone who understands these signals can steer on them in a targeted way. That is exactly what SEO does.

Why is this important for your SEO?

Understanding how Google works makes SEO concrete instead of mysterious. You then know that a page can only rank once it is found, understood and judged relevant. Every optimization falls under one of those steps.

At Customer Impact we translate that into choices that really deliver traffic and enquiries. We do not optimize for the search engine as a goal in itself, but because a higher position in B2B leads to more conversations with the right decision-makers. Increasingly, alongside the classic SERP, an AI answer also plays a role, so we keep both channels in view.
