I advertise my hubs on a variety of areas: Facebook Pages and group, Pinterest, and Google +1 groups. I also have a website where I syndicate my hub's titles and summaries. One click, and the reader is brought into my HubPages. By advertising on my website, I am able to tag each hub with my own words and phrases. Hopefully, this brings more traffic. I have never had one of my hubs unfeatured, but I've only been writing for HubPages for two months.
