Search Engine Optimization
Search Engine Optimization, or SEO for short, covers all the measures used to make a website appear higher up in the results lists of search services like Google. Because the top results get the most visitors, SEO is an important economic factor for many companies.
Anyone searching for something on the internet types a few words into a search box and gets a long list of results. Most people only click on the first three or four results. Search Engine Optimization, usually abbreviated as SEO, means: designing a website so that it lands as high up as possible in this list. You don’t pay directly for this; instead, you change your own site and its content. This is what distinguishes SEO from advertisements, which appear above the list and cost money per click. The German term translates literally as “Suchmaschinenoptimierung,” and both terms mean the same thing.
Why first place is worth so much money
Search engines are the most important source of customers for many companies. An online shop for running shoes depends on appearing early in searches for “buy running shoes.” Studies repeatedly show a similar picture: the first result often gets more clicks than positions two through five combined. Almost nobody lands on page two of the results anymore.
That’s why an entire industry has grown up around SEO. There are agencies, analysis tools, and specialists who make their living from it alone. A better position in the results list brings visitors without having to pay for every click. It’s different with ads: as soon as the advertising budget runs out, visibility disappears immediately.
Conversely, SEO is risky because the rules aren’t made by the company itself. Google changes its ranking system several times a year. Some websites lose half their visitors overnight as a result. Anyone who depends solely on search engines therefore faces a concentration risk.
What search engines evaluate on a page
A search engine sends programs through the internet that read and store page after page. These programs are called crawlers. What’s collected forms a huge directory, the index. When a search query is made, the internet itself isn’t searched—only this directory. A ranking calculation then decides which result appears at the top.
Hundreds of signals feed into this calculation. The words in the text matter: anyone writing about bicycle repair should also use those words. It also matters how many other websites link to the page. A link counts as a recommendation, and recommendations from reputable sites count for more. Technical factors also play a role, such as how fast the page loads and whether it’s easy to read on a phone.
A common misconception is that SEO consists of repeating a search term as often as possible. That worked twenty years ago and is now recognized and penalized as manipulation. Modern search engines use AI models that capture meaning instead of just counting words. They understand that “bike fixes tire” and “bicycle repair” can mean the same thing. Good content for people is therefore also the best strategy for machines.
SEO in news, products, and the age of chatbots
You encounter SEO constantly in everyday life without noticing it. Recipe pages with long backstories before the actual recipe are a result of SEO thinking. So are headlines like “The 10 Best Headphones 2025,” which are precisely tailored to typical search queries. Comparison portals and guide articles from large shops are also usually built for search engines.
In business news, SEO often comes up in connection with chatbots. When answers come directly from an AI system, nobody clicks through to the source website anymore. Publishers and shops therefore fear declining visitor numbers. A new term has emerged for this: Generative Engine Optimization, meaning optimization aimed at appearing in AI answers at all.
At the same time, AI today generates masses of text written solely for search engines. Google is responding with rules against content that offers no real value. This makes SEO a race: one side optimizes, the other adjusts its ranking system. This is relevant for investors, because advertising and media companies depend heavily on this balance.
