In this chapter, we have discussed how we can check 404 errors in our website, why it is important to eliminate 404 errors, and how we can do so. Not only 404 errors, but we also learned and understood 300, 400, and 500 error messages as well. Then, we have discussed CDN networks and the benefits of using a CDN network. Also, you need to manage third-party plugins in your website properly in order to get an optimized website.

After this, we have discussed screen rotation and how we can use it to optimize our website. Finally, we went through Adobe Flash and recommended not use it.
