Search Engine Optimization is the practice of improving a website so it ranks higher in Google and other search engines. This includes writing clear page titles and descriptions, using proper heading structure, improving page speed, and building content that matches what people are searching for. Good SEO drives free, compounding traffic over time.
The concrete version: a physiotherapist in Rotterdam wants to show up when someone searches "physio Rotterdam knee pain." SEO is everything that makes that happen — a page that actually addresses knee pain, a title that says so plainly, a site that loads fast on a phone, and other reputable sites linking to it. Rankings are earned across all of those at once; there is no single switch to flip.
Why it matters for your project: SEO is dramatically cheaper to build in than to bolt on. Clean page structure, fast load times, sensible URLs, and structured data are decisions made during development — retrofitting them later means paying twice. The honest expectations: results take months, not weeks, and no one can guarantee a ranking. But unlike paid ads, which stop the moment you stop paying, search traffic compounds. A page that ranks keeps sending customers for years.
Technically, SEO ties into how your site is built. Pre-rendered pages (SSG or SSR) give Google complete content to index, and page speed — measured by metrics like LCP — feeds directly into rankings. Fast, well-structured, genuinely useful: that is the whole recipe, and two-thirds of it is engineering.
