Video SEO (vSEO)
Definition - What does Video SEO (vSEO) mean?
Techopedia explains Video SEO (vSEO)
Since actual video data cannot usually be seen by Web crawlers, which are usually built to find text, the conventional SEO process used for video SEO is to use tags and metadata to lead the crawlers to the video. However, some crawlers specifically made for videos can look at video data to know the content to some extent, but this is not reliable and not applicable to most types of videos. To date, the most reliable way to promote videos in searches is for the website to have a video sitemap, which is a basically a gallery of videos being hosted on the site itself. This is because Google usually only accords rich snippets to sites with large video catalogs such as YouTube, Daily Motion and Vimeo, so having a video sitemap tells the search engine that the website also has a large video catalog.
