Search engine optimization is the set of techniques that let your site appear in search results without paying for each click. To get there, you need to understand one simple thing: before ranking your site, Google must first find it, read it and understand it. Three steps, in that order, and each one can block your visibility.

The figures explain why this matters. According to a Backlinko study covering millions of search results, the first organic result captures on average 27.6% of clicks, and the top three positions concentrate roughly 75% of clicks. The first result is ten times more likely to be clicked than the one in tenth position.

For a Belgian SME or self-employed person, the stakes are concrete: being on page two amounts to being invisible. The good news is that the rules of the game are public. Google documents its own workings, and the logic is anything but magic.

How Google works, in three steps

According to Google's official documentation on how search works, everything rests on three successive phases: crawling, indexing and ranking.

Crawling: Google discovers your pages

Google sends out robots, called *crawlers*, that travel the web from link to link. When a robot reaches your site, it follows the internal links to discover your pages. If a page is not linked to any other, the robot may never see it. That is the first reason a well-structured site, with clear links between pages, ranks better.

Indexing: Google reads and files your pages

Once a page is discovered, Google analyzes its content (text, titles, images, structure) and files it in its index, an immense database. A page that is not indexed simply cannot appear in the results. That is why readable content, organized with hierarchical titles and clear words, is easier to index than a wall of text or a page made solely of images.

Ranking: Google decides the order

When a user types a query, Google queries its index and ranks the relevant pages. Hundreds of signals come into play, but three families dominate: the relevance of the content to the search, the technical quality (speed, mobile compatibility) and the authority of the site (notably links from other sites to yours).

The three levers that truly make the difference

There is no need to target the hundreds of signals at once. For an SME, three levers cover most of the work.

Content. Each page must clearly answer a question your customers ask. A plumber in Wavre has every interest in having a page that answers "water heater repair Wavre", rather than a vague homepage that talks about everything. That is the basis of the long tail: targeting specific queries where competition is weaker.

The technical side. A slow site or one poorly adapted to mobile is penalized. In Belgium, half of web traffic comes from smartphones: a page that displays poorly on a phone loses visitors and positions. Display speed has become a ranking criterion in its own right.

Authority. When other credible sites link to yours, Google sees it as a sign of trust. For a Belgian SME, this often goes through serious directories, the local press, partners or suppliers.

Why SEO matters particularly in Belgium

The Belgian market has its specifics. According to the FPS Economy (Statbel survey on the use of ICT, 2023 data), small Belgian companies are more numerous than in France in having a site with advanced features: 70.5% versus 49.2%. Online presence is therefore already widespread, which means competition for top positions is real.

Another specific: the country is multilingual. A company targeting Flanders and Wallonia must think of its search engine optimization in both languages, otherwise it misses half its market. And search is evolving: Google began rolling out its artificial-intelligence-generated summaries (AI Overviews) in 2024, which makes producing clear and structured content even more important, since only such content is picked up in those answers. This is a topic we developed in our article on the evolution of SEO in 2025.

Frequently asked questions

How long before you see SEO results?

Search engine optimization is groundwork. The first effects generally appear after a few months, the time it takes Google to crawl, index and evaluate your site. It is slower than advertising, but the effect lasts over time without paying for each click.

Can I do SEO myself?

The basics (clear content, structured titles, a fast site on mobile) are within reach of a motivated business owner. The more advanced technical aspects and the keyword strategy often benefit from being supported, especially in a competitive market.

Do you need to create a lot of pages?

Quantity is not everything. A few pages that truly answer your customers' precise questions are better than a multitude of empty pages. Each page must have a reason to exist and target a clear search intent.

Does search engine optimization replace advertising?

No, the two are complementary. Advertising gives immediate results but stops as soon as the budget stops. SEO takes longer to get going, but builds a lasting asset. Many SMEs combine both according to their priorities.

Priority action plan

1. Check that Google finds your pages: make sure every important page is accessible from your menu or your internal links.

2. Clarify the content: one page = one precise customer question, with an explicit title and logical subtitles.

3. Take care of mobile and speed: test how your site displays on a smartphone and fix the slow pages.

4. Target the local long tail: aim for precise queries tied to your trade and your region rather than generic words.

5. Build your authority: register in serious directories and forge links with credible sites in your sector.

Search engine optimization is no secret formula: it is the consequence of a site that Google can easily crawl, read and understand. By tackling these foundations in the right order, a Belgian SME gives itself the means to lastingly occupy the positions that capture the bulk of clicks.
