Yes and no. You can lower your data transfer usage by making your web site as efficient as possible. This may mean removing downloadable files — such as Flash presentations, mp3s, videos, and streaming audio — or optimizing your images, which can make your page sizes smaller. But if your site is popular, and too many people are connecting to your site at the same time, you might still exceed your limits.

You can also upgrade to Yahoo! Web Hosting which offers unlimited disk space and data transfer. Learn more about upgrading. This ensures that you won't have to worry about your site's availability, even if you have a spike in traffic. Learn more.
