Optimizing subsequent page load times is crucial for a seamless user experience. To achieve this, developers can employ client-side optimization strategies that improve website navigation. One effective technique is loading assets on hover, ensuring they are available when the user navigates to the next page. Additionally, caching these assets for as long as possible can significantly reduce re-downloads.

Other approaches include utilizing various caching strategies and implementing back-forward cache for a smooth navigation experience. The key is to keep logic simple and avoid complex JavaScript or unnecessary re-renders. It's also essential to profile website performance before and after optimization to ensure improvements, not degradations.
