Optimizing Video-Sharing Sites for SEO
Because search engines can’t directly parse the contents of multimedia, you must take advantage of all opportunities to use your relevant search terms in every video title, description, and ALT tag or any other option you find.
You can often use existing keyword research, meta tags from your website or blog, or optimized text that you’ve already created. For more information on indexing multimedia, see Google.com/Webmasters.
Take advantage of context and form fields, included on video-sharing sites, to make your videos easier to find. Here’s a list:
Title and title meta tag: Try to attract viewers by including relevant search terms in your title and meta tags.
Category or directory: Select or name a category that draws your target audience. It never hurts if the label is a keyword.
Filename: A name such as video12 doesn’t help with SEO as much as tabby-cats-sing-jingle-bells does.
Tag: Use relevant keywords, just as you would with other social media.
ALT tag: Use this type of tag for a short description with a search term — for example, guided meditation mandala.
Long description meta tag: Try to incorporate four to six search terms, just as you would with the page description meta tag on your website.
Content: Surround embedded multimedia elements on any web or social media page with keyword-rich, descriptive content.
Transcription: Transcribe and post a short excerpt from a keyword-loaded portion of your video.
Anchor text: Use keywords in the text link that opens your multimedia file.
RSS and XML: Expand your reach with media RSS and site maps.
