Vimeo's mantra is quality over quantity. Because Vimeo has stricter guidelines for acceptable videos, its processing load is far lighter than YouTube's. And that means it can focus more on maximizing the quality of each video using better encoding techniques. Other benefits:

• Replace video but keep URL: This is one of Vimeo's best features. You can replace any of your existing videos with a new upload without losing its URL, thus keeping all of the likes, comments, stats, and not breaking any embeds that may exist on third-party sites.
• Password protection: You can set a password on any video so that only those with the password can view it. YouTube doesn't have this feature, only allowing videos to be Public, Private, or Unlisted.
• Domain-restricted embeds: Vimeo lets you set which domains are allowed to embed your videos, and you can do this on a per-video basis. This way, you can hide your videos on the Vimeo site itself and only make them viewable on your site.
• Web player branding: Vimeo lets you alter the appearance of its HTML5 web player by inserting your own logo and branding, which is great when embedding videos on your site, whereas embedded YouTube videos always look the same and end with that unsightly suggestions page.
• Advanced analytics: Depending on your subscription level, you can get various levels of analytics, starting with a traffic dashboard and custom reports, going all the way to engagement graphs and Google Analytics integration.
• Plus, Pro, Business, Premium plans: Unlike YouTube, Vimeo is funded by its community rather than advertisers. You CAN use Vimeo for free, but free accounts are limited to 500MB of uploads per week. Vimeo Plus costs $7/month, Pro costs $20/month, Business is $50/month, and the top-tier Vimeo Premium is $75/month.
