One page, one job
A landing page is a page built for a single purpose: to convert a specific visitor into a specific next step. That's the entire difference between a landing page and a normal web page. Your homepage tries to serve everyone — new visitors, existing customers, job seekers, the curious. A landing page serves exactly one type of person arriving with exactly one intent.
Because it has one job, it strips away everything that doesn't serve that job. Often that means removing the navigation menu, the footer full of links, and every path that would let the visitor wander off. What's left is a focused sequence: here's the offer, here's why to trust it, here's the one thing to do next. Focus is the whole point.
