I have found many of the below links useful for generating traffic of increasing back links to my sites. I now get more hits off Google instead of Hubpages. I love the traffic from Hubpages, but traffic from outside is more productive if you look to generate AdSense revenues. When I add my URLs to Google and Yahoo, my bases are covered for the major search engines. Remember Google has search engines for different nations and it has filtered through to these. As you know, your Hubs can be shared through StumbleUpon.com and Digg.com with the toolbar at the bottom of your page.
