I can only imagine if I built a list with these articles how many new contacts/ customers I could have had access to for free.
I'm even ranking for a two word keyword for the number one spot in Google with a whopping 8,817 views!
From the looks of things bookmarking & submitting the feed as well as submitting your article to directories works well, if you don't submit to much to soon.
I used some automation software to help with the process from incansoft( no affiliation.)
Having your keyword in the title and introduction and in the author bio hyper linked can help your ranking, as well as the niche you pick.
I highly recommend adding article marketing to your arsenal if you have the time.
