The backend is like your website’s engine. Users might never see it, but just like a car won’t move without an engine, a site won’t work without a backend. It handles all the behind-the-scenes stuff—like data processing, saving info, and talking to databases. So, when someone visits your site and searches for something, it’s the backend making sure that works fast and smoothly. From keeping things secure to speeding up load times, the backend’s got it all covered. If you want a site that’s quick, safe, and trustworthy, you’ve gotta give the backend some serious love. That way, your site won’t just impress users—it’ll also climb higher in Google rankings.
