Search engines are there to help the million surfers for any terms that they are . Tags assist in Google search algorithms and and surfers - with out them your pages will be hard to find. Tags are as important as catchy title. It surprised me to see and to learn that hubpages.com has now phased out tags on every hub a hubber would submit for publication.
HubPages explains, "Tags and used to be very important on HubPages, but due to abuse by spammers, we developed an automated system that develops tags for Hubs automatically which will ultimately save you time and leave Hubbers less dumbfounded when trying to determine which tags are or are not appropriate."
