I have been writing on HubPages since 2006 and in that time I have accumulated a total of 4,281 followers. This is good because many of those who become followers tend to both visit my other Hubs as well as check out new Hubs when I publish them.
This helps to improve the traffic to my Hubs.
I also have 242 people who have joined HubPages as a result of clicking on a links to my Hubs which I have posted on my blog or other site. Included in the link is a code known as a "Referral Tracker" which gives me credit whenever a person uses that link to visit HubPages and sign up. By signing up after clicking on a link I have posted, I am given credit for recruiting them and receive 10% of the income from the add impressions from Hubs they publish (this 10% comes from the 40% of impression income HubPages receives from clicks so the new Hubber still receives their full 60% of impression income).
While the income I earn from from these Hubbers is not broken out separately on reports, it does add to my overall income from HubPages each month.
To learn how to use and potentially earn some income from the use of Referral Trackers check out the instructions in the HubPage Learning Center here: https://hubpageshelp.com/money/Learning-Center-ref...
