Most businesses don't decide to rebuild their website — they just keep adding to it until it's held together with plugins and hope. If your site takes more than three seconds to load, doesn't truly work on mobile, needs a developer for every change, looks dated next to competitors, or brings in no leads, it's time to rebuild rather than patch.
Speed and mobile come first
Google's research shows bounce rates spike past the 3-second mark, and most visitors are on a phone. A modern rebuild fixes both permanently instead of shaving milliseconds off a broken foundation.
