Which topics work best in attracting visitors on hubpages?
In my opinion, recipes, tips on writing, kids, pets, and anything to do with the internet seem to get the most traffic. For me, I read topics that deal more with the essence of being a good person, how to handle life situations, recipes, pets, and occasionally political topics.
I believe you should certainly write about things you know and things that can benefit someone. For anything else you have an interest in, but not too much knowledge about, put out a request on that topic. Depending on what you're asking, requests also seem to generate quite a bit of traffic.
Some of the things I've written that I thought should get a good response, didn't, yet others I didn't feel so great about seem to have gotten a better response than anticipated.
Just keep writing and you'll find your niche. Good luck!
