You know, to get appear on Google’s search result generally you put Title, Description & Meta tags on your website relevant to your content; similarly to get appear on YouTube’s search result you can add some meta tags while uploading it on YouTube. Currently YouTube has hidden meta tags appearance on video page, because most of people copy the tags and use them in their own video. Also the tag appearance was not more use full for the viewers. But that does not mean you should avoid putting tags on your video. It helps for video discovery and search of your content.
If YouTube has hidden the tag of all video, then how to see it? Here is a tip;
Lets say you watched the following video on YouTube and now you want to see the tags used in this video. If you are using Chrome browser, just do mouse right click and go to view source option.
Then on view source page, press Ctrl+F button and search ‘Keywords’. You will see the lists of meta tags used on this video.
This video has following tags: <meta name=”keywords” content=”flipkart, bansal, sachin bansal, binny bansal, unpluggd, unpluggd 7, 2013, interview, candid, entrepreneur, startup, ecommerce, amazon india, flyte…”>
Idea is not to copy the tags of your competitor, but if you have lists of tag of your competitor’s video then you can use more tags which are being search on YouTube by using adword tool.
Don’t forget that meta tags are the only ranking factors of your video to get discovered organically. Always use the tags while uploading your content on YouTube.
