Here are some best practices for crafting video metadata! If it’s not tagged, it doesn’t ship. Period. You must minimally have a title, a brief description and at least 3-5 keywords before posting your videos to sites like YouTube:

• Stop, Think, Tag: Your video is just a part of the process of driving attention and engagement online. If you don’t properly describe your video, search engines (Google and YouTube!) won’t know to tell people it’s there.
• Maximize: Put as much information into your descriptions as possible. As search engines are able to consume and reference more information, the description of the video becomes more and more important. Transcripts, links to associated and relative content all help get the video ranked higher in search results.
• Always use “video” as a tag. Seriously. It helps.
• Use links in descriptions – back to your website. This is very beneficial for search engine ranking. Place these links at the top of the description to ensure that it can be seen by your audience.
• In the title, be logical, not creative: People don’t search for flowery language, they think more literally. Spicing up your title with alliteration or something smart can make it harder for your audience to find you.
• Example: You name your cooking video “Succulent Scrumptious Steak” after reviewing some information from google you find out that “juicy steak” and “great steak” is searched much more frequently.
