Hi welcome to hub family. Regarding the traffic to hubs.You need to post good content. The way u mentioned is good and one more is you can look at some hubs like fiercy, shinujohn2008, shalini many more are there who gets traffic more than 200 per day. Just try to follow them and add as fans.Thats it.
yep--comment on others hubs and reply to comments on yours-that puts your name in hubtivity which gets you noticed by other hubbers. Hang around in the forums too and when you feel comfortable, participate.
For starters write about your personal experiences and about stuff you know, about humorous incidents, about interesting journeys you've made, about things you like to do, and so on ... got it? Good luck2U!
