• Keywords are possible the most important part of SEO. Choose words (or a grouping of words) that best describes what you're selling, like "new motorcycle for sale, Yamaha motorcycle for sale, selling brand-new motorcycle, motorcycle for sale in Denver, Colorado."
• Look for similar items (or services, I don't know what it is you're offering) for sale elsewhere on the internet and see what people have used for them.
• NOTE: Please do not intentionally choose unrelated categories for your video - these are checked on video upload and will be changed by administration if necessary. Anyone caught abusing the ability to change categories after upload in an effort to get more views will not be tolerated and could be considered misleading, violation could get you banned from Post It Online
