I studied up in the faq about tags...finally, and I applied the technique of, "what would you type in search engine if you were researching topic of your hub and use as your tag PHRASE. As beginner hubbers, I think we have so many tools to use on Hubpages, but it takes time to learn how to use them all to your best advantage. So when we first see tags, we think of single words. Please, if you want to increase your traffic, read thoroughly the faq and other hubbers inputs. I started rewriting my tags just a few days ago and already by traffic is moving more! Thanks Hubbers and Hubpages!
