Hi guys, I am making a mini authority site for google on a keyword that is very easy with 5400 search global and 3600 local monthly. I plan on monetizing through adsense. The top site ranking number one is just pr1 and not much backlinks. Very beatable, on page is decently optimized. Like I said , not unbeatable. Anyway, I did further research and found out that all the related keywords for the site have very low searches per month. My question is do I go ahead and still write those articles just to make my site look like an authority for the keyword or does the traffic from the other articles matter also? Thanks.
