Have you ever checked the tags a YouTube video by viewing the page source and searching for the keywords line, only to be frustrated because not all of the tags are shown? Normally, when there are lots of tags, only about the first five or so can be seen in the page source (depending on the length of the tags), with the last one being partially displayed and followed by an ellipsis, indicating that there are other tags but they're hidden. For instance, out of curiosity, I was wondering what tags were being used in https://www.youtube.com/watch?v=BwfUj84Qc-Y about (ironically) using tags effectively, and here's what I saw in the page source at the end of the keywords line: There are probably many ways to see the other tags but just minutes ago, I discovered a very useful tool called BetterWayToWeb (http://www.betterwaytoweb.com/tag-generator-for-youtube) that shows all of the tags (albeit, in reverse order). As explained at the site, the tool can also be used to generate popular YouTube tags for specified keywords. A simple but powerful tool, in my opinion.
