A custom 404 page can help keep visitors on the site instead of leaving when a page is missing. Instead of showing a plain error, it can suggest related products or categories that match what the person may be looking for. This makes the experience feel smoother and more useful. It also reduces bounce rate, which can help search ranking over time. The suggestions should be simple and clear, not too many options. Do you think showing product suggestions on error pages feels helpful or distracting?
