Tags are keywords, hashtags are keywords with the # sign in front and they essentially do the same thing. We want to make sure our posts are put in front of those who are on that relevant topic.

So if my post is about helping by providing post promotion to 900+ followers for free, I want my post to show up in front of those who are looking for:

1. Free
2. Promotion
3. Resteem

Since this is a community, I want to look for existing tags where I can find my audience such as: free, freesteem, resteem, promo-steem

Now I'd like to add my own unique tag so people can easily find all my posts on free promotion: free-promote, promote-free, steem-free, happy-free-promo, etc.

This can be a little confusing, so tell me if something doesn't make sense.
