Just churn out great hubs-with a topic people will be interested in,give an excellent title,write with passion in English that is grammatically correct and with no spelling errors, and add relevant tags,use a good photo and hit publish.
Repeat this for every hub you publish,and do not forget to reply to comments on your hubs. Also, take time to read other hubs of interest to you and also on topics similar to yours and leave some comments.
Participate in the forums , the hubmob,and the contests for more exposure. Do not forget to facebook and tweet every published hub.
Aha,in due course, you will see yourself being followed. Which will be growing as you publish more hubs of interest.
You can also invite people to follow you. When you follow other hubbers, some may reciprocate as well
