This is a common question. If you have Hubs of actual interest to people, sprinkled with appropriate keywords (keyphrases) and appropriate Tags, you will eventually get search engine traffic.
My visitors are about 1/3 from HubPages and 2/3 from search engines. If I worked at it, my goal would be massive traffic, so the Hub traffic would be somewhat greater, and the search engine traffic would be much, much greater. That would mean an ideal 95%+ from the search engines and 5% or less from HubPages, even though the absolute number from HubPages would be greater than now.
You can help the HubPages community highlight top quality content by ranking this answer up or down.
