Identify the best keywords
To get your video content found, use the right keywords in your title, description, and tags.
The first place to look for the right keywords is YouTube’s autocomplete feature – start typing your seed keyword into the search bar and see how YouTube interprets it by showing autocomplete suggestions:If you have a bunch of keywords, you can automate the process with the help of a specialized keyword research tool. The free version of Rank Tracker (disclosure, I am the creator) allows you to use nine keyword research methods, which are likely to result in thousands of prospective keywords. Don’t worry; you can narrow the selection with the use of custom filters — aim for the highest search volume and the lowest competition.
For something lighter and more convenient, look into Keywords Everywhere. The browser extension allows research of keywords on the go. It greatly augments the autocomplete features of YouTube and Google with valuable metrics.Tags for YouTube is another browser extension that shows the tags for each opened YouTube video. It provides a nice overview of any video ranking for your topic.
RapidTags generate multiple tags related to your topic. Put in the URL or topic of your video and see what tags come up. One downside, though, its free version is limited.
