Well first of all if you want to be part of hubpages just to earn income, it will be obvious and your hubs will most likely not be high quality.Remember to drive massive traffic requires lots of published hubs, but a good quality hub takes a little bit time to write and put together.Therefore you can only write couple hubs a day.Unless you are a typing and publishing robot =).But having 1 good articles instead of 10 poor articles will be much better.Good articles contain more and clear information.Viewers then find that information and see your ads on different topics related to that information.Click Click!They click on your ads to view that information which is being advertised.
But keep these key elements in mind;
-High Quality - Rich Content
-Niche or non-Niche = doesn't really make a difference you can be all over the place
-Find traffic sources
-Search on popular keywords and search terms and write articles based on that
and you should be fine.But keep in mind if you are looking for a get rich quick...You will not find it here, nobody can.But with time and effort you will see results sooner or later.I have seen results on my second day on Hubpages =) not that great of an income but hey its a start!
Wish you luck and the best =) Sincerely Kiwiwi
