Optimize video for google search because search engines can’t (yet) “see” the words coming out of your mouth. So, how do you do this?
Pair you video with a text-based interpretation of the content within your video. Craft this text so it’s “search engine friendly” like any blogger is supposed to do when working with SEO. Now, you’ll get ranked high for your video and humans will click on the link and watch the show. The search engine will skip the show and read the text.
Don’t annotate! Nobody wants to read your script and it won’t be optimized for search engines well; use your own words that are carefully crafted.
