Redirect your 404 pages to a page or a custom URL. Turn them into 301 (page moved), 302 or 307 codes so that search engines aren't so offended by missing pages.

Does the job, and it's an important job.

• See also 404 to 301 Log Manager, a payware addon to extend functionality.

• I do believe that using CloudFlare will hijack your 404 page though. =(
