A URL (Uniform Resource Locator) is the address that tells a browser exactly where a page or file lives on the internet. When you type topdevs.nl/contact or click a link, the URL is what your browser uses to find and load the right content.
Think of it like a postal address. The protocol (https) is the kind of delivery, the domain name is the city and street, and the path after the slash is the house number that points to one exact page. Change a single character and you end up somewhere else, or nowhere at all.
Every link you see on a website is really a URL behind the scenes. A well chosen one is short, human readable, and describes the page. Compare topdevs.nl/services/web-design with topdevs.nl/?p=4821. The first tells a visitor what to expect and is easier for search engines to rank. The way these addresses are organised across a site is its URL structure, and getting it right early saves a lot of pain later.
One detail that trips people up: a URL can keep working even after the page it points to moves. When you rename or relocate a page, a redirect quietly forwards the old address to the new one, so old links and bookmarks do not break. Skip that step and visitors hit a dead 404 instead.
URLs are also case and slash sensitive in ways that surprise people. On many servers /Contact and /contact can be treated as two different pages, and a trailing slash can do the same. Picking one form and sticking to it keeps search engines from seeing duplicate pages and splitting your ranking signals.
At TopDevs we plan clean, stable URLs before a site goes live, so your pages keep their rankings and links never break when the site grows.
