I seen this hubber with about 600 something hubs. On all his hubs he did not have any pictures,videos or anything. He also had a low following considering he had all those hubs,however he has over 1,000,000 views. It seems he constantly writes hubs and not much else. I can not say the hubs are bad, but there not "content is king" exactly. They are at least 500 word though. Do you think a person like this does well with google adsense? He did have really good feedback though strange his following was not as high.
