I have heard that creation is one factor that will help increase traffic and ranking of your website. What do you think about this matter?
Are you referring to hubpages.com? If so it is a good place to get some traffic. I have a few hubs out there and get a couple clicks every week. Their links however are nofollow.
If you're referring to hubpages.com then yes - it's quite a good source for traffic, however, you need to put some effort into building your hubpage, always keeping in mind that it's the traffic (actual visitors) that you want, not Google rankings, i.e. the hubpage should be as carefully prepared as your website.
Hubpages.com is more less equal to answering Yahoo with your URL in the resource box. Both of them will attract few useful traffic although they are no-follow links.
Hub pages are a good way of creating an authority backlink and gain some traffic in the process. If your hub page quality score is improved then the links become dofollow which means links gain link juice and passes page rank.
Yes hubpage is good to convert quality traffic on your site, There are few rule you need to keep in your mind while you want to do hubpage and it's better if you atlest do it freequently update yoru hubpage
