A delay means the impression that the site froze or is not working, and the user leaves. --- ### 2. **Speed = retention** If a site takes longer than 2-3 seconds to load, retention drops sharply: - higher bounce rate - lower page depth - lower engagement --- ### 3. **Performance and responsiveness** A large initial load means: - heavy JS and CSS - a long blocking main thread - a long TTI (Time to Interactive) The result: even after the interface appears, nothing "clicks" and everything freezes. --- ### 4. **SEO (search results)** Google directly factors in loading metrics (LCP, TTI, CLS). A slow initial load means lower ranking and less traffic. --- ### 5. **Mobile users** On 3G/4G, a heavy initial load becomes a disaster. Resources load slowly, JavaScript runs with lag. The user simply closes the tab. --- **Conclusion:** Initial load is the "entry threshold." If it's heavy, nothing that follows matters. The goal is to render and activate the main content as fast as possible and with as little weight as possible.For the reviewerNote to the moderator (optional)Visible only to the moderator.
