Hi epichey, tags are words that you will use in your article. For instance you would use marbles as a tag if you were writing an article on how to play a game of marbles. also it is good to put tag words in the 1st sentence or two of your text, I think it helps search engines find you better. Keeping with the topic of ;marbles; you may use words like game, playing, kid's games, competitions..I try to use 6 - 10 tags, you can add or remove tags anytime during edit. After you enter a tag hit enter and a new box will open so you can enter a new one and so on. When you are done adding tags simply hit continue. I trust this helps. Welcome to Hubpages.
